A condensed version of theseprocedures is in the Operator's and Crew member'sChecklist, TM 1-1510-218-CL. Emergency operationsof avionics equipment are covered when appropriate inChapter 3, Avionics, and are repeated in this sectiononly as safety of flight is affected.9-5.

ResetMASTER CAUTION after each malfunctionto allow systems to respond to subsequentmalfunctions.9-7. ENGINE MALFUNCTION.a. Flight Characteristics Under Partial PowerConditions. There are no unusual flightcharacteristics during single-engine operation as longas airspeed is maintained at or above minimum controlspeed (Vmc ) and power-off stall speeds. The capabilityof the aircraft to climb or maintain level flight dependson configuration, gross weight, altitude, and free airtemperature. Performance and control will improve byfeathering the propeller of the inoperative engine,retracting the landing gear and flaps, and establishingthe appropriate single-engine best rate-of-climb speed(V2/V yse). Minimum control speed (Vmc ) with flapsretracted is approximately 1 knot higher than with flapsat takeoff (40%) position.9-3. DEFINITION OF LANDING TERMS.The term, “Land as soon as possible” is definedas landing at the nearest suitable landing area (e.g.,open field) without delay.
