Well I was sitting here, pretty much ignoring most of what you said...then my cat hopped up onto the keyboard...I got to thinking...
If all there is to a take off judgement is to pull the levers before V1, push them forward after V1,...can a cat be taught that?
I mean cat's have terrific reflexes, are very fast...and if all they have to do is watch the airspeed indicator for V1...maybe we could put a little mouse on the levers to keep her interested...corporate will love the low costs, they never get sick and they work for kibble.
