Folks,
Either times have changed or we are talking about FCTM from Renton versus Payne Field.
I can't speak for the B737.
But I can for virtually all varients of B707/767/747, and in maximum crosswinds T/O you will need considerable into wind aileron to keep the wings level. You will need the "appropriate" rudder and aileron to just stay on the runway, you have to "fly" the aeroplane all the way. I am speaking from having had to use full control deflection to counter the actual (as opposed to reported) wind, on both takeoff and landing.
And, on takeoff, keep your fingers crossed that the "wrong" engine doesn't fail, because published Vmcg and the real thing are two different animals.
Tootle pip!!
