Before Taxi
Flaps ............................................................ .................Check F/O
Move the flaps from Flaps up to Flaps 40 back to Flaps up (i.e., full
travel) to ensure freedom of movement.
If taxi route is through ice, snow, slush or standing water in low
temperatures or if precipitation is falling with temperatures below
freezing, taxi out with the flaps up. Taxiing with the flaps extended
subjects the flaps and flap drives to contamination. Leading edge devices
are also susceptible to slush accumulations.
Call “FLAPS ___” as needed. C
