TM 55-1510-219-10 8-45.  BEFORE LEAVING AIRCRAFT. 1. Wheels-Chocked. 2. Parking brake-As required. NOTE Brakes   should   be   released   after chocks are in place (ramp conditions permitting). 3. Flight controls-Locked. 4. Fuel pumps-Set. a. Standby pumps-OFF b. Aux transfer-AUTO c. Crossfeed-CLOSED 5. Emergency exit lock-As required. 6. Mode 4-As required. 7. Aft cabin light-OFF. 8. Door light-OFF. CAUTION If   strong   winds   are   anticipated while   the   aircraft   is   unattended, the propellers shall be secured to prevent    their    windmilling    with zero engine oil pressure. 9. Walk-around inspection-Complete. Conduct a thorough walk-around inspection,    checking    for    damage,    fluid leaks,   and   levels.      Check   that   covers, tiedowns,     restraints,     safety     pins     and chocks are installed as required. 10. Aircraft   forms-Complete.      In   addition   to established requirements for reporting any system   defects,   unusual   and   excessive operation such as hard landings, etc., the flight  crew  will  also  make  entries  on  DA Form  2408-13  to  indicate  when  limits  in the Operator's Manual have been exceeded. 11. Aircraft   secured-Check;   lock   cabin   door as required. NOTE A cold oil check is unreliable.  Oil should    be    checked    within    10 minutes    after    stopping    engine. Section III.  INSTRUMENT FLIGHT 8-46.  GENERAL. This aircraft is qualified for operation in instrument meteorological    conditions.        Flight    handling,    stability characteristics  and  range  are  approximately  the  same during instrument flight conditions as when under visual flight conditions. 8-47.  INSTRUMENT TAKEOFF. Complete the BEFORE TAKEOFF check. Engage   the   heading   (HDG)   mode   on   the   autopilot computer/control.    (DO  NOT  ENGAGE  AUTOPILOT.) Set   heading   marker   (HDG)   to   runway   heading   and adjust   pitch   bar.      Align   the   aircraft   with   the   runway centerline,   insuring   that   nosewheel   is   straight   before stopping    aircraft.        Hold    brakes    and    complete    the, LINEUP   check.      Insure   that   the   roll   steering   bar   is centered.      Power   application   and   copilot   duties   are identical to those prescribed for a "visual" takeoff.  After the brakes are released, initial directional control should be  accomplished  predominantly  with  the  aid  of  outside visual    references.        As    the    takeoff    progresses,    the crosscheck should transition from outside references to the  Flight  Director  and  airspeed  indicator.    The  rate  of transition is directly proportional to the rate at which the outside   references   deteriorate.      Approaching   rotation speed (V_r), the cross-check should be totally committed to the instruments so that erroneous sensory inputs can be ignored.  At rotation speed, establish takeoff attitude on  the  Flight  Director.    Maintain  this  pitch  attitude  and wings-level  attitude  until  the  aircraft  becomes  airborne. When  both  the  vertical  velocity  indicator  and  altimeter show positive climb indications, retract the landing gear. After   the   landing   gear   is   retracted,   adjust   the   pitch attitude as required to attain best rate-of-climb airspeed (V_y).    Use  PITCH-SYNC  as  required  to  reposition  the Flight  Director  pitch  steering  bar.    Retract  flaps  after obtaining  best  single-engine  rate-of-climb  speed  (V_yse), and    readjust    pitch    as    required.        Control    the    bank attitudes   to   maintain   the   desired   heading.      Support Flight  Director  indications  throughout  the  maneuver  by cross-checking    "raw    data"    information    displayed    on supporting instruments. 8-20
