TM 1-1510-218-10 9-1 CHAPTER 9 EMERGENCY PROCEDURES Section I.  AIRCRAFT SYSTEMS 9-1.  AIRCRAFT SYSTEMS. This   section   describes   the   aircraft's   systems emergencies   that   may   reasonably   be   expected   to occur   and   presents   the   procedures   to   be   followed. Emergency   procedures   are   given   in   checklist   form when   applicable.      A   condensed   version   of   these procedures  is  in  the  Operator's  and  Crew  member's Checklist, TM 1-1510-218-CL.  Emergency operations of avionics equipment are covered when appropriate in Chapter  3,  Avionics,  and  are  repeated  in  this  section only as safety of flight is affected. 9-2.  IMMEDIATE ACTION EMERGENCY CHECKS. Immediate action emergency items are underlined  for  your  reference  and  shall  be  committed to memory.  During an emergency, the checklist will be called for to verify the memory steps performed and to assist     in     completing any     additional emergency procedures. NOTE The urgency of certain emergencies requires immediate action by the pilot.  The most    important    single    consideration    is aircraft control. All procedures are subordinate   to   this   requirement.      Reset MASTER  CAUTION  after  each  malfunction to allow systems to respond to subsequent malfunctions. 9-3.  DEFINITION OF LANDING TERMS. The term, “Land as soon as possible” is defined as  landing  at  the  nearest  suitable  landing  area  (e.g., open field) without delay.  The primary consideration is to ensure the survival of the occupants. The   term,   “Land   as   soon   as   practicable”   is defined as landing at the nearest suitable airfield.  The primary consideration is the urgency of the emergency. 9-4.  AFTER EMERGENCY ACTION. After   a   malfunction   has   occurred,   appropriate emergency actions have been taken, and the aircraft is on the ground, an entry shall be made in the remarks section     of     DA     Form     2408-13-1     describing     the malfunction. 9-5.  EMERGENCY EXITS AND EQUIPMENT. Emergency  exits  and  equipment  are  shown  in Figure 9-1. 9-6.  EMERGENCY ENTRANCE. Entry may be made through the cabin emergency   hatch.    The  hatch   may   be   released   by pulling on its flush-mounted, pull out handle, placarded EMERGENCY  EXIT  PULL  HANDLE  TO  RELEASE. The hatch is of the non-hinged plug type that removes completely   from   the   frame   when   the   latches   are released.    After  the  latches  are  released,  the  hatch may be pushed in to the aircraft. 9-7.  ENGINE MALFUNCTION. a.   Flight Characteristics Under Partial Power Conditions. There are no unusual flight characteristics  during  single-engine  operation  as  long as airspeed is maintained at or above minimum control speed (V_mc) and power-off stall speeds.  The capability of the aircraft to climb or maintain level flight depends on  configuration,  gross  weight,  altitude,  and  free  air temperature.  Performance and control will improve by feathering   the   propeller   of   the   inoperative   engine, retracting the landing gear and flaps, and establishing the appropriate single-engine best rate-of-climb speed (V₂/V_yse).      Minimum   control   speed   (V_mc)   with   flaps retracted is approximately 1 knot higher than with flaps at takeoff (40%) position.
