in the 320 training(and later some Sim's)one can have the Sidestick fail on takeoff-not very amusing running off the end(stuff that nightmares are made of)...A good lesson in 'looking'during the take off roll-to the 'Iron cross'control displacement indicator,and having it displaced from the norm(on the horizon)..During the takeoff,should the indicator not be where directed,might be a good tome to stop-or hand over control.
I seem to remember the control indicators on the B727,and can't one displace the indic'on the TO/run(nose down elevator??)
Cheers
