ONE ENGINE INOPERATIVE
MAXIMUM CRUISE POWER
1900 RPM
ISA + 20 °C
NOTES: DURING OPERATION WITH ICE VANE EXTENDED, TORQUE WILL DECREASE. IF
ORIGINAL POWER IS NOT OR CANNOT BE RESET, TRUE AIRSPEED WILL DECREASE
APPROXIMATELY 20 KNOTS AND FUEL FLOW WILL DECREASE APPROXIMATELY 7%. IF
ORIGINAL POWER IS RESET, TRUE AIRSPEED WILL BE UNCHANGED AND FUEL FLOW
WILL INCREASE APPROXIMATELY 30 LB/HR/ENG.
IOAT, TORQUE, AND FUEL FLOW BASED ON 12,000 POUNDS.
TO OBTAIN FUEL FLOW PER ENGINE, DIVIDE THE TOTAL FUEL FLOW VALUE FOR THE
CORRESPONDING ALTITUDE BY TWO.
