When I was conducting Ground Cats, all that mattered was that they were practical and that the poor victim left having learned something.
And yes, I know I used to waffle on but I hated the bŁoody things and it was a way of killing time!
But I was a bit surprised how little some pilots knew about FMS switchery in the Vickers FunBus.....or how to do JetPlan corrections methodically.
