Having flown the 777-200 RR and GE engine variants (and also eventually the 777-300 GE) for around 17 years, I cannot say I ever noticed much of a difference in the elevator feel at rotation and lift-off. 🤷🏼♂️
That is interesting. I find it pretty differentiated, including both the force required during the initial rotation and the position of the yoke to get the aircraft to pitch up. The GE variants seem to need much less elevator and almost leave the ground of their own accord once the rotation is under way, save for the little hiatus (common to all) as the stab/elevator goes into ground effect. I do fly other aircraft with what would be regarded as very low stick force per g, so maybe I’m being overly sensitive? Does seem to be a common impression amongst those I operate with, though.
