Icing Definition
On the Ground and Takeoff
Icing conditions exist when the OAT is 10 Degrees C or below AND visible moisture in any form is present (rain, snow, sleet, ice, clouds, or fog with visibility of 1 mile or less)
Icing conditions also exist when the OAT is 10 Degrees C or below when operation on ramps, taxiways, or runways where surface snow, slush, ice, or standing water may be ingested by the engines, or freeze on engines, nacelles, or engine sensor probes
Icing Caution on the Ground
Do not rely on visual icing condtions or ice detector actuation to turn on the Anti-Icing System. Use the temperature and visible moisture criteria. Delaying the use of the Anti-Icing System until ice build-up is visible from the cockpit may result in ice ingetstion and possible engine damage or flameout.
Icing Definition
In Flight
Icing conditions may exist whenever the TAT is 10 Degrees C or below AND visibile moisture in any form is present (rain, snow, sleet, ice, clouds, or fog with visibility of 1 mile or less)
Icing Caution in Flight
Notwithstanding ice detector monitoring, the crew remains responsible for monitoring potential icing conditions and for manual activiation of the Ice Protection System if icing conditions are present and the Ice Detection System is not activating the Ice Protection System
