H 13.  Departure briefing – Complete. * 8-32.  LINE UP. O 1.  Transponder   /   TCAS   /   Wx   Radar   –   As required. 2.  LANDING,   TAXI,   RECOG,   and   STROBE lights – ON. 3.  Anti-ice/deice – As required. 4.  ENGINE ANTI-ICE – As required. 5.  AUTO IGNITION – ARM. 6.  CONDITION levers – HIGH IDLE. 7.  Power stabilized – 27% torque minimum. 8-33.  TAKEOFF. To   aid   in   planning   the   takeoff   and   to   obtain maximum  aircraft  performance,  make  full  use  of  the information   affecting   takeoff   shown   in   Chapter   7. The   data   shown   was   achieved   by   setting   brakes, setting takeoff power, and then releasing brakes.  The takeoff  will  be  accomplished  in  accordance  with  the appropriate Army Training Manual (ATM). 8-34.  AFTER TAKEOFF. During  takeoff  and  climb,  the  pilot  flying the aircraft should avoid adjusting controls located on the  aft  portion  of  the  extended pedestal    to    preclude    inducing    spatial disorientation. 1.  GEAR – UP. 2.  FLAPS (105 KIAS) – UP. 3.  Climb power – Set. 4.  LANDING/TAXI lights – OFF. 5.  Wings and nacelles – Check. 8-35.  CLIMB. a.    Cruise Climb.  Cruise climb is performed at a  speed  that  is  the  best  combination  of  climb,  fuel burn-off, and distance covered.  Set propellers at 1900 RPM and torque at maximum allowable (or maximum climb   ITT,   monitor   N₁).      Adhere   to   the   following airspeed schedule as closely as possible.
