The level of technical knowledge hereabouts never ceases to amaze me, quite astounding.
I agree. On my last aircraft programme (rotary) there were many complex design issues and unique design features, but by far the most impressive feat was Westland working out the load shedding convention in case of single or double generator failure. (Tough **** if all 3 went, but as all Mull of Kintyre watchers know helicopters can glide at will to any landing point
). Mind bogglingly complex on an electrical system that was within 0.04kVA of max. They'd nothing to play with, complicated by (as beagle mentions) the usual requirement for a "get you home" mode. The Chief Designer's reply was typically robust. "Get you home?". You'll get a ###### parachute and be happy".
