ISA + 20oC
During operation with ice vanes extended, torque will decrease approximately 14 percentage points
(E.G., 64%-14 percentage points=50%). If desired, original power may be reset, provided TGT time is
not exceeded. If original power is reset, fuel flow will increase approximately 35 LBS/HR/ENG and true
airspeed will be unchanged. If original power is not or cannot be reset, fuel flow will decrease
approximately 8% and true airspeed will be reduced approximately 30 knots.
