Thanks for your answers. I am now told that Boeing state that “wing anti-icing should compliment ground de-icing”, which would suggest that it should be put on with the engine A/I after start. Either way, it is apparent that not all of us 737 operators are using the same procedure. I was just curious if there had been a recent change of policy that I was not aware of.
PS Does anyone know if the wing A/I logic (thrust lever position, squat switch, etc) is the same across all series?
