TM 55-1510-220-10 CHAPTER 9 EMERGENCY PROCEDURES Section I.  AIRCRAFT SYSTEMS 9-1.  AIRCRAFT SYSTEMS. This section describes the aircraft 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   Crewmember's   Checklist,   TM   55-1510- 220-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   LANDING   IMMEDIATELY   is   defined   as executing    a    landing    without    delay.        (The    primary consideration is to assure the survival of occupants.) The term   LAND   AS   SOON   AS   POSSIBLE   is   defined   as executing  a  landing  at  the  nearest  suitable  landing  area without     delay.          The     term     LAND     AS     SOON     AS PRACTICABLE  is  defined  as  executing  a  landing  to  the nearest suitable airfield. 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 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 nonhinged plug type which removes completely from the frame  when  the  latches  are  released.    After  the  latches are released, the hatch may be pushed in. 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 above power-off stall speed.  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 (Vyse).  Minimum control speed  (V mc )  with  flaps  retracted  is  approximately  1  knot higher than with flaps at takeoff (40%) position. 9-1
