A Smooth Skin Can Save Serious Money

Non-Stick Vehicles
A good way to save money

Every woman knows that unblemished skin is essential to looking good.

In modern vehicle aerodynamics, not only does a smooth skin look good, but it can also save large amounts of money for the owner or operator.

The aviation industry has been aware of the importance of a smooth finish for many years, and has developed many ways of reducing skin friction. Flush rivets and streamlined fairings go a long way to increasing achievable airspeed and reducing drag (and therefore fuel burn).

The latest generation of transport aircraft now increasingly use composite materials such as carbon fibre to construct airframe components. Such materials offer two main advantages – a high strength to weight ratio, combined with the ability to be joined using high technology adhesives rather than rivets.

However, an aircraft in line service becomes dirty over time, and the dirt particles accumulate to cause a breakdown in the airflow over the wing surface, thus increasing drag. Paint finishes also start to blemish and break down, causing further erosion of the erstwhile smooth finish.

This is where the relatively new science of Nanotechnology offers significant improvements to aerodynamic performance.

Nanotechnology is defined as “The manipulation of matter at an atomic or molecular level.” The standard unit of measurement is the nanometre, which is defined as being one billionth of a metre. To put this into context, an atom of Helium measures about 0.1 nanometres!

Developments in this field have enabled the production of commercially available coatings designed to bond to a vehicle structure, forming a perfectly smooth coating which prevents the accumulation of dirt and debris and helps to shed water, and protect paintwork.

The process for applying the nano-emulsion is simple.

Firstly, the airframe is thoroughly cleaned, and then treated with an acidic solution which has the effect of positively polarising the surface. This enables the nano-emulsion to completely bond with the structure.

The final stage is applying the coating itself. Once cured, the coating is fully bonded to the surface.

The fully cured coating is extremely thin – 100 times thinner than a human hair, and the total weight of the treatment adds just four ounces (113g) to the weight of the aircraft.

It is estimated that a treated aircraft will return a fuel saving of somewhere between 1% and 2%!

A number of airlines have been quick to evaluate these products. In 2011, EasyJet, grasped the opportunity to run trials, and had eight of their aircraft treated with the nano coating.

A carrier such as EasyJet’s fuel bill will represent about 40% of its total costs, and be in the region of £750,000,000 ($1,185,000,000) per year. A 1.5% saving on this figure is a massive £11.25 Million per year. As fuel prices only ever go up, these figures are just a start.

There are also additional hidden savings, as treated aircraft will need washing and repainting less frequently.

Another significant saving may be made on the amount of green taxes incurred by the operator. In Europe, these taxes are quite high, and a drop in fuel burn results in a proportional reduction in greenhouse gases.

Recently, British Airways announced that they are conducting a trial on a Boeing B777-200, and is hoping to see cost saving in excess of £100,000 in the year long evaluation.

This technology is not just limited to aircraft operators. The coating is equally effective in a marine environment, and coating ship hulls will improve hydrodynamic qualities.

Road vehicles can also benefit from improvements to their aerodynamics and haulage operators with a large fleet may well be able to enjoy cost savings as well.

So our womenfolk were right all along. Smooth is essential!

Night Departure

Tail lights vanishing into a darkening sky,

A symbol of your leaving,

An intermittent spark of fading cherry red,

Dwarfed, and made miniscule by the vastness of night,

The lonely silver disc of the moon, bathes the landscape with surreal intensity,

In it’s unfeeling spotlight, for an unknown reason, I feel desolate,

You, speeding across the roof of the world, chasing the eastern mystic dawn,

I gaze at the last seductive blink of light, yet distance and darkness conspire,

The universe wins, and defeated, I stand alone,

I trudge to the car park, wearing shoes of lead,

Having nowhere to go, yet no reason to stay,

Out! Out! onto the highway, My reality here,

Yet My spirit soars east, chasing, never catching,

Radio taunts, me, romantic songs,

I turn south, and briefly look up,

I see another, red, winking, vanishing into a darkening sky

A Summer Fly-in at a Country Airfield

The sky was an azure bowl, and the scent of new-mown grass lay heavy in the mid-morning sunshine. The playful breeze toyed with the surrounding tents, causing them to billow and sway, like an insane troupe of Turkish Belly Dancers.

I wandered along, past ranks of parked aircraft, each one trembling slightly at each soft breath of wind. To the other side of the runway stood a mediaeval cluster of tents, gazebos and stalls, each accumulating untidy gaggles of pilots and aviation enthusiasts.

The subdued hubbub of conversation was suddenly overwhelmed with the electronic hiss of the public address system. The disembodied voice of the commentator rolled across the airfield, bouncing back from the surrounding hills, the echoes garbled and distorted.

The announcement was garbled, but I caught a few words and realised that a lost boy was being held at the First Aid tent. I wondered idly where his parents were. At the Burger Van? The Mobile Bar?  Or were they queuing to use the lavatories?

The murmuring was quiet at first – almost beneath the threshold of hearing, but it gradually became persistent, growing in volume and engorging with tone. Suddenly the day was split apart with the thunderous yet melodious note of three vintage aeroplanes flying in perfect formation – appearing low over the trees at the Eastern end of the airfield.

The staccato high-pitched whine of motor-driven cameras was just audible above the palpable growl of the engines. Every spectator looked skyward, envying the superb airmanship shown by the pilots.

The flight swooped majestically around the airfield, the sun glinting on the polished cowlings, refracting off wings as they looped and rolled above the South Downs. They were gone as suddenly as they arrived, and peace reigned once more.

As I continued my ramble towards the end of the runway, I heard the much softer note of another aircraft engine. I spotted a single light in the sky, which grew steadily until it metamorphosed into a small aircraft.

With its engine at idle, the aeroplane passed me, sighing softly as it touched down on the bumpy grass, its nose nodding up and down, affirming a good landing. As I watched, it slowed to walking pace, and taxied sedately towards the low Nissan Hut housing Air-Traffic Control.

A sallow youth wearing a very grubby High Visibility Tabard, stood glumly at the head of a vacant parking slot, and  began to unenthusiastically wave his arms at the pilot, marshalling him into the vacant position.

More incoherence from the Tannoy indicated something would soon be happening. Looking up, I faintly recognised the profile of an aeroplane, obviously at high altitude – a ghostly insect crawling across the window of the sky.

Suddenly, the blue fabric of the sky was cross-stitched with a web of pristine white trails, each creating patterns of gently expanding white.

Blossoming into multi-coloured parachutes, each action-man figure oscillated like a small pendulum, expanding as they approached the white cross laid on the grass.

With a graceful pull on their control lines, each man arrested his descent, landing as softly as thistledown. An appreciative crowd clapped, as the team collected their deflated chutes.

Shadows were lengthening as I drove out of the car park. A Spitfire suddenly howled overhead, just in front of my car, its wheels already tucking up into its belly, its sides bronzed and gilded by the setting sun. Disappearing into the heat shimmer, it left only the echoes of its engine to testify to its existence.

Have a Safe(r) Flight!

So, you are going on holiday. Fabulous! You have packed your clothes for your two weeks away, you’ve bought your travel insurance, reserved a rental car, and still have a sore arm from getting the necessary inoculations and vaccinations.

But how much thought have you given to your personal safety on board the aeroplane?

If you answered “none” to this question, then you are part of the huge majority of air travellers who arrive at the airport blissfully ignorant of the potential risks attached to their chosen mode of travel.

Air travel is an extremely safe and efficient way of getting to distant places. Statistics seem to support this, including the oft-quoted “You are safer flying than you are driving in a car to the airport”  Whilst this may have a degree of accuracy, the fact still remains that aircraft accidents do still happen, some of which are serious. With a little care and forethought, you can reduce your exposure to these possible risks, by taking some simple steps yourself.

So, back to my question. How much thought have you given to your personal safety on board the aeroplane?  Or, to put it another way, when do you start thinking about your on-board safety?  A week before travelling? The day before? When you are sitting in your seat, waiting to take off?

Modern airliners are generally very reliable, but there are phases of flight that are more dangerous than others. Interestingly, more aircraft accidents occur during take off and landing than at any other time of flight. This is particularly true in some of the less developed countries around the globe, where flight safety is degraded as a result of under-investment.

In the highly unlikely event that the aircraft should suffer a serious in-flight problem, an emergency landing may be needed, and it may be necessary to “abandon ship” down the escape slides. There may be limited time for the cabin crew to prepare you for doing this, so you need to think a little about the slides.

The slides are made of a very tough neoprene, and are inflated automatically should a door be opened once the aircraft has left the gate. Naturally, you will have been requested to watch the safety demonstration, and refer to the safety card, but the vast majority of you will have been far too busy reading the newspaper, and listening to your iPods to have done so!

The reason that I mention this here, is that despite the instructions to remove high heeled shoes, and to leave bags behind during a slide evacuation, some individuals still place more value on their laptop computer and their bottle of duty free than on their own lives, or those of fellow passengers!

Amazingly, during a fairly recent evacuation of a Boeing 777 in Houston, passengers were observed jumping down the escape slides carrying their wheelie bags, bottles, and other bits of variegated hand baggage. Selfish and stupid in equal measures!

You may then have to walk across broken glass and damaged suitcases once you get off the slide.

For that reason, you should consider what you would wear on the flight. Stout, flat-soled yet comfortable footwear such as Deck Shoes, Moccasins, Training Shoes, and Flat soled business shoes are a must. I recommend that you resist the temptation to remove these shoes and put on the in-flight socks until the take off and climb is completed and the aeroplane is safely in the cruise.

Approaches and landings carry a higher statistical risk of emergencies, so you should put your “sensible” shoes back on at the top of the descent. This is normally indicated when you hear the engine note diminish as the power is reduced, about 30 minutes before arrival time. You may also hear a passenger announcement from the pilots at this point.

I also recommend that you invest in a simple body belt, so that you can carry your passport and travel documents easily. Its more practical than carrying them in a shirt or blouse pocket, and it may save you being delayed if you do have to evacuate the aeroplane.

Those passengers who have footwear and a passport may be swiftly re-booked onto another flight. Those who don’t will probably have to wait for some time in the airport until their passports and belongings have been collected by airport staff.

Your last consideration before leaving home for the airport should be the rest of your clothing, and the material from which it is made. I recommend that you wear clothes produced from natural products, such as cotton.

These materials may burn in the event of fire, but they will offer you more protection from flames than man-made fibres such as Nylon, which is highly flammable.

Now, lets consider your flight. You have boarded the aeroplane, and have been welcomed aboard by a smiling Flight Attendant. Soft background music will be playing, and you will shuffle to your allocated seat. This is easy in a well-lit cabin.

Now imagine the same cabin, darkened, filled with smoke and full of passengers. Your ability to see will be severely limited. Therefore, you should count the number of seatbacks that you pass on your way to your seat. This will enable you to locate the exits in poor lighting conditions should you need to escape from the aeroplane in an emergency.

Once at your designated seat, you should stow your carry-on baggage in the overhead lockers.  Nothing could possibly go wrong with this.  Or could it?

This is an area for concern. The overhead lockers are not designed to carry very heavy items, yet passengers are often observed struggling to lift huge sports bags and holdalls, boxes, and even very heavy cases into the overhead locker above your seat.

In the event of a forced landing, these lockers may deform, resulting in the doors springing open, thus allowing the contents to fall on the passenger below – in this case you!

If you feel unhappy about the load in the overhead stowage, talk to a crewmember and ask, or even insist that the bag is removed from the overhead, placed in another locker, or put in the aircraft hold.

Now, before you sit down, you should use the opportunity to have a quick check of the area around your seat. Find the lifejacket stowage, and check that there is a lifejacket in it!

It may surprise you, but it is a sad fact that every summer, I witness passengers walking off aeroplanes with life jackets stuffed in their hand baggage. Not only is this a criminal act, it is also a very selfish one, bearing in mind that the jacket is safety equipment, and could potentially mean the difference between survival and death.

It is a legal requirement that a life jacket is available for each seat, and the aircraft will not depart until you have one – even if the only water you will fly over is the Manchester Ship Canal!

Most reputable European, North and South American and Australasian airline’s aircraft engineers will always check that every seat has a life jacket before the aircraft operates its first flight of the day. However, you may be flying on the third, sixth, or even the twelfth sector, so its always possible that someone has stolen the jacket as a souvenir since the engineering safety check.

Furthermore, you may be flying to a remote region on a carrier operated by a small and under-developed country. There is no guarantee that these checks have been performed, so you should take a peek to make sure that you have a lifejacket.

Once the aircraft is safely away from the gate, and starts taxying to the runway, the safety demonstration commences. This will consist of either a pre-recorded film, or a demonstration given by the cabin attendants.

I strongly urge you to watch the film or demonstration. You may be a regular traveller on a Boeing 737, or an Airbus, but each airline will have a different seating layout, different emergency lighting systems, and different types of safety equipment, so assuming that you don’t need to watch the demonstration is dangerous complacency.

Numerous safety items are covered on the safety demonstration; how to fasten and release your safety belt, how to use the drop down oxygen masks, and how to fit and secure a life jacket. You will also be advised to read the safety card, which will either be contained in the seatback pocket, or in some cases, riveted to the seatback in front of you.

The reason that you are instructed to read the safety card, is that it will contain information that the safety demonstration doesn’t cover. This will include how to open the doors and emergency escape hatches, and how to adopt the correct “brace” position in the event of making an emergency landing.

Pulling this card out to read it as the aircraft is skidding to a stop in a field is a little late in the day – so please read the information on the card whilst you are taxying out.

You may feel justified in ignoring the safety demonstration for numerous reasons. I was recently presenting a safety course and I asked a frequent flyer why she chose to ignore the demonstration. Her response was a common one: “It’s a bit patronising – any fool knows how to fasten a safety belt” Her frequent flyer colleagues all nodded their agreement.

Most passengers will be highly familiar with the operation of a seat belt, as they use one every day whilst driving the car. Think about where the belt release is. Its down by your hip.

Now, where is the belt fastener on an aeroplane? Its in the middle of your stomach.

Bodies have been recovered from wrecked aircraft, bearing trauma wounds to the hips, where the victim’s hands have been scrabbling to find the belt buckle that was in fact sitting in the middle of their stomach.

Some of these individuals survived the crash, only to be suffocated in smoke because they were unable to undo their seatbelts. Reviewing the operation of the seatbelt in the safety demonstration is done to remind passengers that the belt is different to the ones that they may be more familiar with.

You will also be shown how to put on and use the cabin emergency oxygen system.

Aircraft are pressurised to give a comfortable environment similar to normal air pressure at about 8,000 feet.

Very occasionally a fault may cause a drop in cabin pressure, and the air may become too thin to breathe comfortably. Therefore, oxygen masks will automatically drop from cubbyholes overhead each passenger seat. It is important that you put the mask on quickly, as it is possible to lose consciousness for a brief period if you don’t.

Many aircraft use chemical oxygen generators to produce oxygen, as it saves the requirement to carry large metal tanks. When activated, these generators combine two chemicals to produce oxygen, which is then delivered by a plastic tube to the mask. A by-product of this reaction is heat.

The generators are located in compartments built into the overhead lockers. Over time, they will be covered in a layer of dust. This dust heats up, and creates the smell of burning. This may create panic, as some passengers will assume that the aircraft is on fire.

So, what may happen in reality?

You may feel a slight popping in your ears and the cabin may start to become quite chilly. This is to be expected if the cabin altitude is rising. At some point the safety systems will detect the falling pressure, and the oxygen masks will automatically drop out of their stowages under the overhead lockers.

You may hear a pre-recorded passenger announcement that reminds you to put your mask on, and informs you that an emergency descent has been started.

If you have paid attention to the safety demonstration, you will have already grabbed the nearest mask, and will have put it on. The air flows as soon as the rubber tube is pulled.

Don’t worry about pulling the mask out of its connection to the air supply – the rubber tube is very strong and secured very tightly, and you do need to pull the mask firmly in order to start the oxygen flow.

Whilst this is going on, the Pilots will be doing their emergency drills. They will have donned their masks, and will have immediately put the aircraft into a fairly steep descent to get the aircraft quickly to an altitude where the air is breathable.

Modern aircraft wings are designed to create as much lift as possible, but lift is now the last thing that is needed. The pilot will have extended the speed brakes, which are large hydraulically operated panels located on the top surface of the wing.

Once these are lifted up into the airflow, they interfere with the lift, and the rate of descent is now much faster. They also cause some turbulence and noise, and this may add to the sense of alarm in the cabin.

However, you must remember, that the apparent feelings of being in extreme danger are deceptive, and whilst this is an emergency situation, you will be quite safe. Aircraft depressurisation is practiced by the crews regularly in the flight simulators, and is relatively easy to handle and resolve.

The last item that is normally demonstrated is the use of the lifejacket. Lifejackets are generally similar in operation regardless of manufacturer or airline. They will be simply placed over the head, and either tied around the waist with canvas cords, or secured with nylon webbing and plastic snap fasteners.

They are inflated by pulling a toggle on the front of the jacket, which discharges a CO2 cylinder into the jacket.

Although lifejackets are designed to have no “inside” or “outside” they are best worn with the CO2 cylinder outside, as the metal cartridge becomes very cold after discharging the gas, and may cause burns if left touching the skin. It is imperative that jackets are not inflated inside the aircraft cabin, as they will either get ripped, or will cause obstructions in a densely packed cabin.

Should you forget this, and fire your jacket early, you may deflate it easily by unclipping the inflation tube (the one that is normally used for topping up the jacket by mouth) and pushing your finger into the tube end. Inside is a Schrader valve similar to that used on a car tyre. Simply press the stud in the middle and compress the jacket to deflate it. Once outside the aircraft cabin, two or three deep breaths should re-inflate the jacket to the point where it will support you in the water.

If you are instructed to put on your lifejackets, then there will be an element of panic throughout the cabin. I strongly suggest that after you have donned your jacket and tied or buckled it up, you briefly release your seat belt and stand up!

It will be too late to discover that you have tied the jacket (and yourself) to either the seat frame, or your fellow passengers once the aircraft has ditched. Doing this ensures that the jacket is secured, and that you can still exit the aircraft when required to!

Aircraft typically have an approach and landing speed of anything from 150 knots (130 mph) to about 120 knots (105 mph) but in an abnormal or emergency situation this could be higher. As you will appreciate, under the rapid deceleration of an emergency landing, anything not secured in the cabin will become a projectile, and will travel through the cabin at very high speed. This will include unsecured items of hand baggage, food carts, and other pieces of aircraft equipment.

Aircraft structures are designed to withstand loads of up to nine times normal gravity, but under a crash landing scenario, these limits may be exceeded, and the cabin may start to deform during the deceleration.

The safety card will contain details of the correct brace position to be adopted should a forced landing need to be made. The brace position is designed to minimise the whiplash effects of rapid deceleration, and to protect the head from injury.

Some authorities suggest that bending forwards, and clasping your arms under your thighs will offer the best chances for survival. I personally prefer the brace position used by British Airways. This brace position is adopted by leaning as far forward as possible, and placing your hands over your head.

You should then place your feet flat on the floor, and move them backwards until they touch the baggage restraint bar under your seat. This will guarantee that your feet are behind the line of your knees, thereby ensuring that your legs won’t swing forwards under deceleration loads, and smash your shins into the seat structure in front of you.

I also suggest that although it is a natural tendency to interlace your fingers when you place your hands over your head, that you don’t do it!

If you are right handed, place your right hand on your head first, and then protect that hand by placing your left hand over the top of it. This will make certain that even if the baggage lockers above your head collapse onto your hands, you will not have all your fingers broken and will still be able to unfasten your seat belt, and still have the use of your good hand.

Taking your dream holiday trip of seeing Orang-Utans in the wilds of Borneo or Indonesia, may well involve a considerable amount of flying with air carriers of dubious or unknown quality. You wouldn’t travel without insurance or vaccinations – so surely investing fifteen minutes to watch and understand a safety demonstration is time well spent!

Now, its time to take a reality check.

According to the UK Civil Aviation Authority, during the period from 1992 – 2001, UK airlines carried 802 million passengers with no fatalities!  Quite an impressive record in fact.

The biggest UK Airline operates 285,000 flights per year. Over the last five years, they have only had to evacuate an aircraft on two occasions. These evacuations were only conducted as a safety precaution, rather than as the result of a cabin fire. This means that statistically speaking, you stand a one in 712,500 chance of having to evacuate an aircraft.

To put that further into perspective, The UK’s Health and Safety Executive estimate that the chances of you dying as a result of an aircraft crash are one in 125,000,000 passenger journeys. In fact, they calculate that you stand a one in 16,800 chance of being killed in a road traffic accident.

So, you are relatively safe in the air – but how safe are you once you check into your hotel? Do you know the risks? Have you thought about your welfare? This will be covered in a later posting.

 

Fast Food, Aeroplanes and Problems with Bicycles

As those who occasionally read my postings will know, my normal writing haunt is a local branch of Costa coffee, sipping at a medium skinny wet latte with an extra shot. 
Just so that I don’t come across as boring and predictable, I am sitting on my friend’s terrace in Coto De Caza, a small community of houses nestled around a golf course and country club, tucked away in the foothills of the California Hills, not far from Rancho Santa Margarita. 
Instead of my normal coffee, I am drinking a chilled bottle of Betty IPA, made by the Hangar 24 micro brewery based at Redlands, CA. This has proved to be a very good choice. America now has a thriving micro brewery sector, all producing some excellent ales. This one caught my eye for no other reason than it was packaged in a box with a picture of a B-17 bomber nose section, complete with a nose-art pin up girl. The aircrcraft was called Betty, so being a total aviation person (Anorak) I just had to buy it.  
Unusually for Southern California, it is, what we Brits call “pissing down” and the temperature is so cold that I am almost considering changing from my shorts and tee shirt into trousers and fleece. 
I have been up to LA today, and spent some relaxing time visiting Hollywood Boulevard and Sunset Boulevard. Having checked the hand and footprints outside the Chinese Theatre, I am surprised to see that I have bigger hands and feet than Tom Cruise, and the same sizes as Arnold Schwarzenegger. I guess that working out doesn’t make your feet bigger, just your chest and shoulders. 
On the other hand, Vin Diesel makes me look like a dwarf, and Clint Eastwood is only marginally bigger than I am. This made my day (Punk) and I felt lucky all the way back down to Sunset, looking for a certain burger joint in which to have lunch. 
Now, whilst I am not a regular user of fast food outlets, I still use them from time to time.  It’s odd that in the UK we have a very limited selection. We have franchised MacDonalds in virtually every town and city and a home grown chain called Burger King, and that’s about it if you want a burger. I have to say it – MacDonalds in the UK (rather than in the USA) compares unfavourably. 
Mind you, it’s not all bad news for MacDonalds. I was on a business trip a while ago, to Bandar Seri Begawan in Brunei, where I enjoyed a very nice halal chicken burger at the MacDonalds outlet. On another trip to the Far East, I watched an elephant and rider use the Maccy D’s drive-through in Bangkok with no problem, despite the fact that a few years ago, I was banned from riding my humble bicycle through the MacDonalds drive through in Staines-upon-Thames on the grounds that I would “hold up traffic”. 
Always up for intellectual debate, I took issue with the rude attitude of the guardian of the “Drive-Thru” The spotty faced manager was quite explicit and refused to accept my argument that as all vehicles passed through the drive-through at less than walking pace, I was hardly holding up traffic. I also explained to the simpleton that a bicycle was in fact a vehicle and that I had to obey the road traffic act like all other road users. He countered this by saying that it was for my own protection as I may have an accident. 
Really?  
Oh, I guess I could drop my chips, or maybe spill my drink. I couldn’t conceive of any circumstances in an almost stationary drive-through, in which I would be placing myself in a hazardous situation. I stood more risk of getting a serious dose of e-coli from the lad with an obvious sebaceous gland problem than I was of facing imminent death or injury from vehicles.  
By now, I really was holding the traffic up, so I did eventually get served, and wishing him a cheery “Have a nice day” I went on my way. 
I noticed that a few days later there was a sign banning bicycles from using the drive through. This is the mentality of immature management and justification of stopping a safe activity on the grounds of health and safety.  
Anyway, grumpy old git rant over, and getting back to the plot…

The very best burgers on the planet are served at any branch of “In’n’ Out Burgers”. This is a very small chain of burger shops, indigenous to only Southern California. I discovered this best kept secret a few years ago, when visiting the same friends for a vacation.
I had taken a day out to do some light aircraft flying out of Santa Ana (Orange County) International Airport, also known as John Wayne International. I had rented an Evektor Sport Star light aeroplane from Sunrise Aviation, and had spent a happy few hours cruising up and down the west coast, from John Wayne to San Diego, and then back as far up the coast as Santa Barbara, flying overhead Los Angeles International. America is a fabulous place for a private pilot to fly. Try overflying London Heathrow at 4000 feet, and you’ll probably get shot down!  My routing then swung inland, to potter along past the Hollywood sign, and thence back to land at John Wayne. 

Above: The Evektor SportStar after my West Coast flight.

I landed, settled my account and as I was now officially ravenous, I jumped in my hire car, and headed onto the highway. I found In’n’Out by accident, but with some help from the counter staff I ordered a Double Double (Double burger, double cheese, double onions ) and I was recommended to have it “Animal” style. This involved having a special sauce and relish applied. I also ordered fries and a coke. 

I have to say, the place was heaving. I got issued ticket number 61. After a ten minute wait, they were calling tickets 43 and 44. I kicked back and filled in my log book, carefully adding the hours and minutes. 
At last, my number was called, and I was passed a neat red tray, measuring about 18 inches by 12 inches, upon which were a cardboard tray of fries, and a nicely wrapped burger. The flavours in the burger were excellent, and the burgers themselves were made of proper minced beef, rather than the compressed and reconstituted meat that fills so many other burger buns.  

The fries were crisp, and the whole meal was not only good value, but stuck in my memory as being of very good quality. 
I wasn’t disappointed today either. The In’n’Out on Sunset was overwhelmed with customers, and it was only 11:50. I had to wait again, but the wait was worth it as the quality was still very good. And the cost was just under seven bucks. 
And so,I’m sitting here, in the gathering gloom, typing this blog, prior to making a report on trip advisor. 
Thanks to the very hard working youngsters on duty today… you Rock!

The Guardian of the Skies

The Guardian of the Skies

The Pilot has a trusty friend, who’s heard, but never seen,

Who issues forth instructions, in a never ending stream,

The calming voice, in times of stress, our anchor to the ground,

The measured tones, in hours of need, a truly welcome sound
When we’re “uncertain of position” or have a crisis in the air,

It’s good to know you have a friend, who’s always waiting there,

When fuel is low, and met is poor, you’re losing V.M.C.,

That’s when you’ll really value, the folk in A.T.C.,
It’s easy for us pilots, to infringe somebodies zone,

A moments inattention in the hurry to get home,

Then we get admonished by the ATCO, we’ve unhinged,

Who curtly, politely, tells us, his airspace we’ve infringed
When things are getting busy, near an airports cluttered skies,

Our invisible supporter, lends another pair of eyes,

On flying a tricky clearance, your jangled nerves she’ll settle,

As she vectors you quite safely, amongst the heavy metal
Next time you go aloft, spare a moment for the chap,

Who commands the little lines of blue, upon your half mil map,

Don’t gripe about the airspace, that in the UKs rife,

Or curse the ATCOs down below, one day they’ll save your life 

Electric Taxi – A New Brand New Era in Green Aviation Practice

.Ask anyone in the street about pollution and noise, and most folk will immediately talk about the road transport industry, or, if like me, they live near a major airport, then they would probably refer to the airlines.

Over the last fifty years, air travel has opened up a whole new dimension to travellers. Whether travelling on business, or taking the family away, air travel enables people to reach some of the remotest parts of our planet.

During the early and mid parts of the 20th century, air travel was expensive, and only those travellers with access to a large amount of disposable wealth could afford to fly. 

This was in part caused by the relative lack of supporting infrastructure, but the size of aircraft was also a limiting factor.

The biggest direct operating cost for any airline is that of fuel, and the current smaller aeroplanes were unable to offer the economies of scale necessary to place flying within the reach of the average man. 

To put this into perspective, in the early 1960s, the workhorse of the sky was the Boeing B707, which had a seating capacity of about 140. 

On the 22nd January 1970 Pan Am introduced the very first Boeing 747-100 into service. This aeroplane changed the face of aviation forever.  With its massive seating capacity, of more than double that of the 707, the costs for air travel fell dramatically, and even the poorest backpacker could save enough money to make a transatlantic or transpacific flight.

Over the years, developments of the 747 have continued, and as an example, a British Airways 747-400 will carry 345 passengers over vast distances.

But there are always other factors.  The 1973 oil crisis made fuel costs escalate rapidly, and a number of airlines went out of business. Those that survived recognised the need for newer far more fuel efficient aircraft.

Aircraft manufacturers rose to the challenge, and many new aeroplane were developed, constructed from much lighter materials, including polymers and carbon fibre materials. 

Engine manufacturers have developed cleaner, quieter and far more fuel efficient engines, and new software driven control systems enable aircraft to fly far higher, out of the worst of the weather, and at altitudes where engines are even more frugal.

Sadly, this is still not enough.  The global energy crisis continues, and international concern with  climate change is driving fuel costs upwards.

Airlines are looking to save costs wherever they can.  Most airlines will defer operating the Auxiliary Power Unit (APU) until shortly before boarding, and some airlines have established a policy that requires aircraft to be taxied with one engine shut down.

The economics of this are sound, and saving may be made.

According to Airbus Industrie an Airbus A320 fitted with CFM56 engines will burn 250kg of fuel conducting a twenty minute average taxi time. A single engine taxi of the same duration will burn a reduced amount of 190kg.

Using IATA fuel data, jet fuel (Jet A-1) costs £0.3613 per kilo so a single engine taxi will cost the operator £68.65.  Two engines £72.26. This is doubled effectively, as the aircraft also has to taxi in after landing, which again, will take an average of twenty minutes.

Throughout 2014 fuel prices fell by an average of 42.8%, so it is reasonable to assume that they could rise again by the same amount, giving taxi costs of between £98.03 and ££103.19. 

A very simple costing taking into account British Airways fleet of 105 Airbuses, assumes that each aircraft flies 5 sectors a day (5×2 taxies = 10 x 20 minutes x 105) that’s a massive 350 hours of taxiing. 

350 hours x 60 = 21,000 minutes @ 12.5kg/min = 262,500 kg = 262.50 tonnes!

Now the figures look very different. In the above example, fuel currently costs £361.25 per tonne.  

£94,828 to just taxi around the airfield. Remember this is just a single days operation for one short haul fleet. 

Operators will be very keen to both minimise taxi times, and to reduce costs as much as possible during taxiing.

Airbus have been working on a new self propelled taxying system for the Airbus A320 series, known as eTaxi.

This system utilises a powerful air cooled electric motor that drives the main landing gear wheels via a self contained gearbox.

Powered is provided by the APU generator. The eTaxi motor has sufficient power and torque to enable the aircraft to be reversed off the parking stand, and then taxied to the holding point for the departure runway. At this point, the engines may be started.

Naturally, current procedures and checklists would have to be amended and modified to reflect the use of eTaxi to ensure continuation of current ground movement safety.

The eTaxi system offers many benefits.  Airbus’s own studies have shown that even greater fuel savings may be made than by using single engine taxying. 

Using the AP/eTaxi and a single engine for taxying equates to a fuel burn of 140kg, and full electric taxying only 40kg for the same 20 minute taxy.  

 Using the same fleet data as before, the savings are considerable. 

350 hours x 60 = 21,000 minutes @ 2kg/min = kg = 42.00 tonnes!

With fuel in our example currently costing £361.25 per tonne, 42 tonnes costs £15,172.50, a massive daily saving of £79,655.50!

Naturally,  there is a weight penalty for the eTaxi equipment, consisting of motor, gearbox, wiring harness and software and control equipment, but Airbus Industrie quotes this as being about an extra 400kg, and over a 500nm sector, this would require an additional fuel burn of 16kg.

Overall the use of eTaxi with both engines shut down, and including a 5 minute engine warm up and a 3 minute engine cool down, will offer a trip fuel saving of about 3% on a typical A320 sector of 700nm. 

So, the airline accountants will be happy with the considerable direct financial savings.  However, there are many other associated benefits by using an eTaxi. 

During taxying operations, aircraft frequently have to stop, accelerate, turn and hold in position.  This places wear on the brakes, and incurs fuel penalties every time that the thrust levers are opened to recommence taxying.  

As eTaxi is a direct drive system, the normal wheel brakes become redundant, the braking being delivered through the gearbox itself.  

 Environmentally, eTaxi makes a lot of sense.  The use of clean electricity for ground movements will significantly reduce the amount of NOx (Nitrogen Oxides such as Nitric Oxide and Nitrogen Dioxide) and CO (Carbon Monoxide) found in the local atmosphere.  Noise levels will also be significantly reduced. 

An additional benefit is a reduced exposure to the risk of the engine ingesting foreign objects, and extending the time between mandated engine inspections and checks.  

Bearing in mind that the biggest cost for an airline is fuel. Last year British Airways spent £3.5 Billion pounds on fuel. Most large national carriers will be spending about the same.  The figures are almost too large to contemplate. 

It would appear then, that any additional costs in retrofitting such devices to an existing fleet will pay for itself many times over, and any airline that specifies new deliveries without this option are potentially wasting millions.

Stars In The Sky

Yesterday, I was sitting in Costa Coffee in Petersfield, trying to warm up and dry out.  The morning outside was, in pilot-speak “Claggy”, and the mist was draping itself seductively over the landscape.  I had just travelled the best part of 80 miles to get my scooter inspected prior to applying to get it onto the British vehicle register. 

The journey on the motorway was dull, boring, and miserable, and the continental trucks buffeted the bike around, competing with the blustery wind to make me work hard to keep the machine following a straight line.

So I decided to stop in Petersfield to get out of the fine misty rain, and glug back some Java.

I pulled out my trusty IPad, and started to write this article.  The subject matter has been playing on my mind for a good few months now, and having a few minutes spare, I will launch into it without further ado.

The catalyst for this sudden desire to get the article written was the news that Harrison Ford, a man for whom I have great admiration, had crash landed his vintage aeroplane whilst taking off from Santa Monica airport. 

Our Mister Ford is a keen pilot, and holds both single engine and twin engine licences, together with a helicopter licence.  He owns a number of aircraft, and is in love with flying to the extent that – in his words “I will fly up the coast for a cheeseburger”

As an aviation enthusiast (anorak) I love any films related to flight, flying, or aeroplanes.  My film collection is littered with films such as Top Gun (which must be the seminal aviation movie for the 80s) Air America, The Great Waldo Pepper, Those Magnificent Men in Their Flying Machines, and the Flight of the Phoenix.

I decided that it would be interesting to see how many other Hollywood stars who appeared in such movies actually had piloting experience.

There are one or two well known high profile pilots, such as John Travolta, who owns a number of aircraft, and has a home on an air park in Florida.  He also operates a Boeing 707 bearing Quantas livery, which he flies regularly.

His nearby neighbour in California, one Clint Eastwood has been a qualified helicopter pilot for over thirty years, as well as being a keen environmentalist. 

Fellow actor and song wright, Kris Kristoffersson was also a helicopter pilot, having been taught by the U.S. military, and serving in Germany.  Leaving the army in 1965, he became a commercial helicopter pilot, serving oil platforms in Southern Louisiana for three years before making it big in the music industry, and then more latterly, the movies 

The diminutive Tom Cruise, who played the lead role of Pete “Maverick” Mitchell in the film Top Gun is a pilot in real life as well.  Having qualified in Canada, he owns a P51 Mustang, and a Pitts   Special. Not content with just flying aircraft, he also likes to jump,out of them, and in a keen parachutist. This, in my opinion, makes him a certifiable lunatic – but, hey, each to his own. 

Morgan Freeman also flies, and holds a Private licence.  He too has experienced the thrill and freedom that flying offers.  As a younger man he was an aircraft engineer in the USAF, and had aspirations of being a fighter pilot. I think he made the right choice, because as a successful movie star he can afford to fly whatever he likes….

The late, great James Stewart was a full Colonel in the USAF, and flew many combat missions during the Second World War, and was a highly decorated pilot.  He also appeared in the famous film The Flight of the Phoenix, and appeared in the starring  role in the biopic of Charles Lindburgh. However, his wartime experiences affected him profoundly, and he was averse to appearing in war films. 

Now, let’s move on to Star Trek.  Stark Trek epitomises the pinnacle of what aviation could become;  flying in what is effectively four dimensions.  The cast of this show is positively filled with an abundance of pilots.

James Doohan, who played Chief Engineer “Scottie” flew during the Second World War as a liaison pilot, flying Taylorcraft Auster single engined aircraft, liaising with Canadian Artillery units. He was a natural and exuberant pilot, and was reprimanded for slaloming his aircraft between telegraph poles in around Salisbury Plain, when operating from RAF Andover. 

Creator and director of the Star Trek franchise, Gene Rodenberry was a bomber pilot during the Second World War, flying B17 Flying Fortresses in the Pacific theatre.  He flew 89 combat missions, and was awarded both the Distinguished Flying Medal, and the Air Medal. He retired from the USAF holding the rank of Captain.

Subsequently, he went on to work for Pan American, flying Lockheed Constellations.  Strangely, he left his aviation connections behind, and before creating the series, he enrolled as a police officer in the LAPD. 

Michael Dorn, (Lieutentant Worf) is an accomplished and experienced pilot too. – and has owned a number of classic American ex-military jets, including a T33 trainer, and F86 Sabre, and a Sabreliner.  He is also very privileged to have flown with both the Blue Angels and the Thunderbirds.

Kurt Russell, joins the ranks of celebrity aviators.  The star of films such as Backdraught, and Vanilla Sky, and long time partner to Goldie Hawn holds a private licence for both single and multi engine aeroplanes.  He is also heavily involved in the aviation charity Wings of Hope. 

Action man Steve McQueen was also a very keen aviator. Having had a very dismal and fractured childhood, Steve developed a love for motor racing, fast cars and motorcycles.  He owned a collection of both, and performed a lot of his own stunts.  He is particularly renowned for the motorcycle chase sequence in The Great Escape, and for the high speed car chase in the film Bullit.  

It must be a hand-eye coordination thing, because he also fell in love with aviation.  

Or it could possibly be because his natural father was a stunt pilot with a Barnstormer Flying Circus!

Steve owned and flew a 1945 Boeing Stearman biplane, a Piper J-3 Cub, and a very rare Pitcairn PA-8 which was used by the U.S. ace Eddie Rickenbacker when he flew for the U.S. postal service.

George Peppard of “The A Team” fame was a talented pilot, and flew most of the aerial sequences in the film “The Blue Max” in which he starred as a German Air Force pilot.   He also piloted his own Learjet, which he used for commuting.

Jack Pallance, was selected by the USAF for pilot training, but a serious aircraft crash, which severely burned his face prevented him from flying thereafter.  

It’s also important not to forget the ladies in aviation.

Angelina Jolie is a qualified private pilot and flies a Cirrus SR-22. The model Giesele Bundchen has gained her wings, as has the British TV personality Carol Vorderman.  

Hilary Swank who, coincidentally, played the part of Amelia Earhart has also got a licence.

It’s not just the movie and TV personalities that have been gripped by the thrill of flying. 

Country Singer Alan Jackson has a private licence for both single engine and twins, and ex Van Halen rocker Dave Lee Roth has a helicopter licence.

Gary Numan, the Techno-Pop icon of the 1970s and front man of Tubeway Army is passionate about flying.  He qualified as a pilot and operated a North American Harvard for 15 years on the UK Airshow circuit. 

Bruce Dickinson, lead singer of heavy rock group Iron Maiden is also a flier.  However, his enthusiasm took him one stage further than most of his contemporaries, who are, in the main, private pilots.  He decided that he would gain his commercial licence, and in fact flew for the now defunct UK based airline Astraeus, flying Boeing 757/767 types. He now owns an aviation company based at St Athan in Wales. 

Probably the most famous musician with a licence is John Denver.  During a musical career that spanned a couple of decades, he too fell in love with flying.  Taught to fly by his Father, a record breaking USAF officer (who flew a B-58 Hustler supersonic bomber) he also owned and operated many different aeroplanes, including a Learjet, a Christen Eagle aerobatic biplane, and a pair of Cessna 210 utility planes.  

Many of Johns songs were about aviation or space travel. 

Sadly, John died in an air crash, when flying  his recently acquired Rutan Long EZ which crashed on a Californian beach, killing him instantly.

So, next time you watch a film, and think that the actor or actress is a “Lovey” and a soft shrinking violet, you may be doing them a great dis-service. Not only may they be doing a good percentage of their own stunts, but they may be better qualified than you are!

 

  

No Flying Today – Ops Scrubbed

I wrote this after wasting a day at a little grass airfield in Southern England, waiting for the grey overcast, and the heavy rain and showers to blow through. – typical cold front weather. The airfield – Popham in Hampshire was, and still is the home of the Spitfire flying club, and on that morning it was pretty atmospheric, and I just got to thinking. This is the result.

For those unfamiliar with the UK flying licences, the reference in the poem to the IMC is the Instrument Meteorological Conditions Rating, held by pilots who are qualified to fly on instruments, in cloud.

No Flying Today – Ops Scrubbed

The weather at the airfield, was gloomy wet, and grey,
The rains lashed down, the clouds whipped past, a dreary, soggy day,
I mooched about the clubhouse, and heaved a mighty sigh,
And cursed the fickle gods above, who wouldn’t let me fly.

So I sat there glum, dejected, and sipped my tepid tea,
When a rheumy eyed old warbird, plonked down next to me,
And as he sat, I glanced around, and there I chanced to see,
Proud but faded, on his chest, a single DFC.

I turned away, and sipped my tea, which I add, was weak,
I made to go, and drained my cup, and then I heard him speak
“Don’t feel cheated old chap, this weather will soon pass by,
And if you fly this morning, then you will surely die”

“What makes you so sure?” I asked, “Why should it be me?”
“I have flown in cloud before, I have my IMC”
He chuckled quietly, and then, before he spoke,
He looked at me, and politely cleared his throat

Alone, inside the club house, with the rain still crashing down,
I noticed that my new companion’s face was creased up in a frown,
He grasped my arm, leaned forwards, and peered closely at my face,
His voice was low, insistent, then he rushed on a-pace

“It was on a ropy day like this, in the summer, of ’43,
When I scrambled in my Spitfire, to patrol the cold North Sea,
I was supposed to track a warship, the best the Hun had got,
Then pass my observations to the Navy, for them to make a plot.

Once airborne, I was soon enveloped in solid looking cloud,
Which as I discovered later was to be my burial shroud,
I stared upon my gauges, nailed airspeed and AI
And then I saw some green above, where I should have seen the sky

It took a few eternities, before it all sunk in,
I was fully inverted, sir, and also in a spin,
I pushed the stick, I kicked the bars, and pulled every stunt I knew,
But nothing could recover it, there was nothing I could do

The next thing I remember, is sitting on my arse,
watching as my kite burned out, scorching, black, the grass,
It was just then that I noticed, with a feeling of sick dread,
That the pilot was in the cockpit, and he was surely dead

So, old son, take note from me, advice that you should heed,
Don’t trust to luck, or the instincts of your breed,
Instruments, like people, sometimes fail, or lie,
and if you blindly follow them, then, like me, you’ll surely die.

So, One pilot to another, I say to you, old chap,
Don’t bugger about in clouds, watch the landscape, and your maps,
Only fly when birds do, don’t take needless chances,
don’t fly in bad weather, or in iffy circumstances

I considered all his comments, and thought perhaps he’s right,
I turned to thank him for his guidance, and he’d disappeared from sight,
I looked around, but he was gone, or was he there at all?
Then I saw his young and carefree face, staring from the photo on the wall

I read the caption, inscribed upon the frame, and this is what it said

Pilot Officer Jim Smithers, DFC
Killed in Action 1943, aged 19
And, I realised he Was Dead

Airport visit

This is another one from my back catalogue. I wrote this whilst working as a part time crew bus driver, when I was raising money to pay some big bills. The scene was London’s Gatwick Airport South Terminal. The Northern terminal wasn’t built at the time of writing.

I found it in a folder whilst unpacking some boxes that I took out of the loft.

So here it is…..

Airport Visit

Yellow sodium lights, string upon string, row upon row,
Casting a yellow aura onto the pregnant clouds,
Whilst the world slumbers, this is a land of insomnia,
Never sleeping, teeming with life

I pass through the doors, into this concrete and chrome citadel,
It’s artificial warmth engulfs me, bright neon and noise,
Smells of stale burgers and stale humanity, crowded yet empty,
A different world – an alien place

Wandering through this manmade canyon, yellow stalactites offering directions,
Avoiding the endless cleaners, driving their powered brooms, scarabs of the night,
Ever watchful, vigilant, evading mobile cages of luggage,
Destined for who knows where?

Dante’s hell here, tens of sentient corpses, in limbo,
Strewn like victims on stereotype couches – the un-dead,
Awaiting their flight into the future,
The cheerful obnoxiousness of a giant orange kiosk, serving processed juice.

Musical, the chimes demand attention, the disembodied voice,
Reaching into the furthest nooks and crannies – no escape,
Calling the faithful to the altar of travel,
A tired policeman, gun on hip, drinking plastic coffee from a cardboard cup

As I walk by a party of arrivals dribble from the customs hall, motley collection of searching faces,
Meeters and greeters surge forward clipboards held aloft like religious talismen,
Their overspill of emotion floods me, drowning me, relief, tears, tiredness all at once,
The elderly couple tightly embrace, oblivious to anyone but each other

Deeper I penetrate into this strange land, my eyes assaulted by TV screens that force feed data,
Boldly, I step onto the rubber walkway, driving me into the maw of the machine to be processed,
Journeys end! Departures, and I go to the check in desk,
The uniformed clone launches a computer designed smile at me, chants a litany of questions to appease the gods,

I’ve passed the test, and weigh my bags,watching, devoid of emotion, disengaged,
They lurch away, into a dark oblivion, nostalgia hits…will I ever see them again?
I stand and appraise my fellow travellers; the lady in the two piece, face taut, fearful,
The drunken louts in suits with Nikons round their necks

I see a weary figure, a foreign lady, pushing her cleaning cart like a mobile penance,
How many toilets has she cleaned today, how many will she clean tomorrow?
Will the pretty girl ever see the soldier she’s kissing goodbye again?
The future seems so uncertain, and I share their insecurity

I am alone. No one to wave farewell to, no one to miss, or send a card,
A piece of business flotsam, jostled by the tides of commerce,
Cast wherever the capricious winds of profit blow me,
Oh no – A loud stag party with braying laughs and cowboy hats,

Happy and sad, birth and death – it all happens here,
The total gamut of human emotions and life; deceit, betrayal, love and loyalty,
But emotions can’t be X Rayed, or found by customs – prohibited articles?
Just people, all suffering the common condition of confusion

At last we’re moving towards the rubicon,
Passport in sweaty hand, boarding pass clamped between gritted teeth,
Shuffling like convicts towards the scaffold,
A bored security guard barely glances at me or my papers as I pass through,

Out of the warm cloying fugg, and into the drizzle, the smell of kerosene in the air like mist,
The sleek belly of the aircraft, illuminated by intermittent flashes of Amber and red,
I’m dwarfed by its size, and the impatient whine of its power,
The raindrops hit me, disguising my tears, as I shuffle forwards to embark

The night is then ripped apart, as I stand at the hatch, mesmerised,
A cluster of lights race past me, rotating, clawing their way up the fabric of the night,
Suddenly absorbed by the clouds, with only the lonely baying of jets to testify to it’s existence.
I turn, and see yellow sodium lights, stirring upon string, row upon row
