Hi RR_NDB

Yes. I don't think the problem of confusion can be overstated, here. There were two pilots on board this aircraft who, for 30 seconds, at least, had an extremely compromised situational...

Out here in the west we call that "side-saddle". Only in this case, the cowboy is heading sideways.

RR_NDB

i am trying to be objective, and generous. The SideStick is evocative of "A breed apart", and with "One Type Rating" family style, it certainly fits the bill. I am sad to say it is this...

Howdy.

I considered between, on the outer frame of the console R/L. That makes for a busy console, but also makes it easy to obtain the controls of the side that is working, if one is inop, also...

I learned from an old Navy pilot. His brand of heresy never left me. An aircraft in flight is not lifted by the upper surface, it is pushed, from beneath. The upper surface is not relevant to flight,...
