<<Why trust a newly fitted and unfamiliar piece of equipment in abysmal weather?>>
There's not that much to the kit – ask those who have used it – and it is intrinsically accurate. And the weather again – why not run your eyes over the earlier posts on weather (I even put up some photos to explain).
<<Why approach the coast at high speed in an aircraft that can hover? >>
Ask those who fly them what is a fast approach and why, etc …..
Ah! the comfort zone that is the airworthiness waffle – if a car runs off a cliff because a deviation sign sent them down the wrong track, would it matter if the car had an MOT? Perhaps a parallel debate would run on whether it would have stopped in time if the brakes were checked but surely the big question should be why it took the wrong track in the first place.
