Ground operations in icing conditions (OAT Below -7)
Max Engine Capability is 120 minutes
Engine run 20 TPR(42% N1) for 30 sec at interval not greater than 60 minutes.
Takeoff must be commenced within the 2nd 60 minute interval .
Taxi - in time must be counted as part of the 1st 60 minute interval when engine was not de-iced prior to engine starting.
Ground operations in Icing conditions when OAT is 3 degree or below
Engine static run 50% N1 before commencing take off roll
In -flight moderate to severe icing
Fan ice shedding procedure
Quickly reduce thrust to idle for 5 seconds then restore the required thrust.
If vibration persists, advance thrust lever to Max Climb N1 for at least 2
seconds, then resume normal thrust management..
