When I did a (refresher) conversion onto the B737-800, a very experienced pilot instructor from SAS was of the opinion that in limiting crosswinds FULL aileron should be applied during rotate to keep the wings level
I wonder if that very experienced pilot instructor from SAS had the fortitude to write to Boeing stating he had done measured tests during line flying and that full aileron was needed and that Boeing should henceforth accept his recommendations against the Boeing test pilots figures....
Very experienced pilots sometimes have a tendency to have their own personal gimmicks and swear by them.
