TM 1-1510-224-10 (4) Altitude alerter Check.  Set as required. (5) Transponder As required. 6. Lights As required. NOTE Landing    lights    may    be    used    for takeoff    to    assist    in    avoiding    bird strikes and to make the aircraft more visible  while  operating  in  congested areas. 8-25.  TAKEOFF. To   aid   in   planning   the   takeoff   and   to   obtain maximum   aircraft   performance,   make   full   use   of   the information which affects takeoff, as shown in Chapter 7. The  data  shown  is  achieved  by  setting  brakes,  setting static takeoff power, and then releasing brakes.  Normal takeoff  may  be  modified  by  starting  the  takeoff  roll  prior to attaining takeoff power.  This will result in a smoother takeoff, but will invalidate all subsequent field performance data. a. Normal   Takeoff.      After   the   Line   Up   check   is complete, smoothly apply power to the setting determined from the appropriate Static Takeoff Power at 1700    RPM    chart.        Release    brakes    and    maintain directional  control  with  nosewheel  steering  and  rudder, while   maintaining   wings   level   with   ailerons.      The   pilot should retain a light hold on the power levers through the takeoff   and   be   ready   to   initiate   abort   procedures   if required. The copilot should ensure that the AUTOFEATHER   advisory    lights    are    illuminated    and monitor  engine  torque  during  the  takeoff  roll.    As  the aircraft   accelerates,   engine   torque   will   increase,   but should not exceed engine limits (torque or TGT).  As the copilot  calls  VI,  the  pilot  will  remove  his  hand  from  the POWER levers.  The copilot will call rotate at V, and the pilot will commence a smooth, positive aircraft rotation to an   indicated   pitch   attitude   of   7°.      When   two   positive climb  indications  are  observed,  the  landing  gear  will  be retracted. b. Crosswind Takeoff.    Position  the  aileron  control into  the  wind  at  the  start  of  the  takeoff  roll  to  maintain  a wings level attitude.  Under strong crosswind conditions, leading with upwind power at the beginning of the takeoff roll  will  assist  in  maintaining  directional  control.    As  the nosewheel  comes  off  the  ground,  the  rudder  is  used  as necessary  to  prevent  turning  (crabbing)  into  the  wind. Rotate  in  a  positive  manner  to  keep  from  side-skipping as  weight  is  lifted  from  the  shock  struts.    To  prevent damage to the landing gear, in the event that the aircraft were  to  settle  back  onto  the  runway,  remain  in  slipping flight  until  well  clear  of  the  ground,  then  crab  into  the wind to continue a straight flight path. c. Minimum Run Takeoff.  Not applicable. d. Obstacle Clearance Climb.  Obtain performance data from Chapter 7 using field performance data. 8-26.  AFTER TAKEOFF. WARNING Immediately   after   takeoff,   the   pilot flying the aircraft should avoid adjusting  controls  located  on  the  aft portion  of  the  extended  pedestal  to preclude inducing spatial disorientation. With   both   engines   operating,   the   aircraft   will rapidly   accelerate   through   V2.      Allow   the   aircraft   to continue  accelerating  to  the  two  engine  climb  speed,  or the  cruise  climb  schedule,  as  applicable.    Retract  the flaps when safely airborne.  The procedural steps are as follows: 1. Gear UP. 2. Flaps UP. 3. LANDING LIGHTS switch OFF. CAUTION Turn  windshield  anti-ice  to  NORMAL when    passing    10,000    feet    AGL    or prior   to   entering   the   freezing   level (whichever   comes   first).      Leave   on until no longer required during descent for landing. High temperature     may     be     selected     as required   after   a   minimum   warm-up period of 15 minutes. 4. WINDSHIELD anti-ice As required. 8-27.  CLIMB. Cruise   climb   is   performed   at   a   speed   which provides a good rate-of-climb.  Propellers should be kept at   1700   RPM.      Lower   propeller   RPM   will   reduce   the amount of cabin noise, but will degrade the aircraft climb performance.    The  following  chart  may  be  used  as  an airspeed schedule. NOTE To increase visibility and safety when operating    in    high    traffic,    a    climb speed of 160 KIAS to 10,000 feet MSL may be used. SL to 10,000 FEET....................................135 KIAS 10,000 to 20,000 FEET.............................130 KIAS 20,000 to 25,000 FEET.............................125 KIAS 8-22
