When operating the ICE PROTECTION in manual mode:
CAUTION
Do not rely on visual airframe icing cues to select engine anti-ice ON.
Use temperature and visual moisture criteria specified in this section.
Delaying the use of engine anti-ice until ice buildup is visible from the flightdeck may result in severe engine damage and/or flameout.

Definition of Icing Conditions
- OAT (on the ground and for takeoff) or TAT (inflight) is 10°C or below, and
- Visibile moisture in any form is present such as clouds, fog with visibility of one mile or less, rain, snow, sleet and ice crystals, or
- When operating on ramps, taxiways, or runways where surface snow, ice, standing water or slush may be ingested by engines and freeze on engines, nacelles, or engine sensor probes.
