A

On the ground, do not rely on visual icing evidence or ice detector actuation to turn on the engine antiicing
system. Use the temperature and visual moisture criteria specified in this section. Delaying the use of the Antiicing system until ice build-up is visible from the flight deck may result in ice ingestion and possible engine damage or
flameout
