Airfoil A/I for take off
HI! I would like to know about your companies SOP concerning the use of the airfoil anti-ice for take off, when icing is expected.
Do you switch it on before brake release for take off?
Do you switch it on once airbone above certain height?
First choice, your airplane is protected once airbone, but you might be severely reducing your RTOW ( runway,climb and obstacles).
Second criteria, if you switch it on above certain height you are still protecting your aircraft, but on the other hand your RTOW is not that penalized (just obstacles and maybe climb).
ANY IDEAS? THANKS A LOT
