Aviation is fixated, quite correctly, on in-flight safety. From the humblest sailplane or microlight to the mightiest 747, safety procedures have to be completed, to ensure that aircraft don’t drop out of the skies like confetti.
Before any aircraft takes flight, it’s crew must conduct a thorough inspection to make sure that it is in a fit state to fly. Cabin attendants will check every door and overhead locker, and ensure that all of their required safety equipment is in place.
Their pilot colleagues will also be checking all flight systems thoroughly. There are two elements to this – the internal cockpit checks, and what is known in the trade, as the “walk-around” or the exterior preflight inspection.
Each item to be inspected is laid out in the Flight Crew Operating Manual, or FCOM, and follows a carefully planned and logical sequence so that no item is left unchecked.
As an instructor, strict adherence to procedures is part of my everyday working life.
Here is my lighthearted look at the external walk-around procedure for the Boeing B747-400.
I think it’s a little better than writing about the procedure I follow on my own, much smaller aeroplane.
Whilst our Jumbo’s on the ground,
Before each flight, we must walk round,
And carefully check so many things,
Are engines fixed, likewise the wings,
Are panels shut, are windows clean,
Do nav lights work, do lenses gleam,
And as a safety-conscious fellow,
Be sure to wear your vest of yellow,
To help you check before night flight,
Be sure to use your bright flashlight,
Do just what the FCOM says,
Check the tyres, and gear door bays,
Check the cowls, and drain mast pipes,
Inspect the engine pylon stripes,
Look at the fin, and check the slats,
The lightning wicks, and Fowler flaps,
For safety’s sake – what could be worse?
Than looking forwards whilst in reverse!
Check the brakes and steering too,
The vacuum outlet for the loo,
The outflow valve, the pitot head,
Oh boy – you should have stayed in bed,
Cos whilst you check in pouring rain,
The captains in the warm – AGAIN!
