Hi fly.net, no that's not a joke.
At least on the classic.
I'll try again, when feasible, we have 30 airplanes, I'll try to make a sort of statistic... :confused:

I hope that the suggestion to regularly taxi commercial aircraft around at 35kts GS purely for the purposes of satisfying one's academic interest is only a joke! :bored:

Let's keep the interesting hypotheses on Tech Log or left to the Test Pilots, eh?

Re dead bands on the elevator in manual reversion. The FCTM states the ailerons also have a dead band. Quote:
"With both systems A and B inoperative, the ailerons and elevator are controlled manually. A noticeable dead band will be observed in both these controls".
