During rotation continue to apply control wheel in the displaced position to keep the wings level during liftoff.
- this is the 737 guide - and it also warns of potential problems around Vmcg.
Better to use what you
need and have
possible yaw problems at low VRs (OEI) than to roll a wing in to the ground and have a
definite problem.
In line with the other thread running on this, I use what I need. I object to seeing a 'fixed' aileron put on in a crosswind before brake release, which seems to be taught in some places.
