If at Vr the stick is moved back a little bit- lets say a 1/4 of the normal required input - will the nose pitch up "a little bit" or does the stick have to go back to a certain point before the nose will even start to rise??
No difference to your Boeing / Cessna or whatever. Elevator deflection purely proportional to stick deflection at this stage. What actually happens depends on how the trim was set (loadsheet etc.). Each takeoff is as per my Boeing days - sometimes it leaps off, sometimes needs a bigger than normal tug etc. - each followed by some sarcy comment about the loadsheet / dispatcher etc. !
The PNF - does he/she have any indication of how much movement the PF has put into the stick??
Not once the TO roll starts - except from looking across!
