I say again, " 'bus linedogs", how much more are you learning about your vunderplane from these pages than what you've managed to extract from the official OM/FCOMs?
Somewhere in the murky depths of my memory I recall the great surprise in the 'bus world, following the VA A340 tailscrape accident at Gatwick, that the 'frame would behave differently above 50' radio height than below it.
If memory serves me right, that quirk was unknown to the early 'bus drivers until after that accident, but I wait to be corrected?
