TM 1-1510-225-10 8A-22 CAUTION Do  not  pull  out  of  the  resulting  dive  too abruptly.  This could cause excessive wing loads and possibly a secondary stall. 5.  Pull   out   of   dive   by   exerting   a   smooth, steady  back  pressure  on  control  wheel, avoiding an accelerated stall and excessive aircraft stresses. 8A-51.  DIVING. Maximum     airspeed     (red     line)     V_mo/M_mo     is 259 KIAS  or  0.52  Mach.      Flight   characteristics   are conventional  throughout  a  dive  maneuver.    However, caution should be used if rough air is encountered after maximum  allowable  dive  speed  has  been  reached. Dive recovery should be very gentle to avoid excessive aircraft stresses. 8A-52.  MANEUVERING FLIGHT. Maneuvering   speed   (V_a)   at   which   full   abrupt control  inputs  can  be  applied  without  exceeding  the design load factor of the aircraft is shown in Chapter 5. The data is based on 12,500 pounds and there are no restrictions  below  this  weight.    There  are  no  unusual characteristics during accelerated flight. 8A-53.  FLIGHT CONTROLS. The   aircraft   is   stable   under   all   normal   flight conditions.      Aileron,   elevator,   rudder,   and   trim   tab controls function effectively throughout all normal flight conditions.  Elevator control forces are relatively light in the   extreme   aft   Center   of   Gravity   (CG)   condition, progressing to moderately high with CG at the forward limit.  Extending and retracting the landing gear causes only   slight   changes   in   control   pressure.      Control pressures  resulting  from  changing  power  settings  or repositioning the flaps are not excessive in the landing configuration  at  the  most  forward  CG.   The  minimum speed  at  which  the  aircraft  can  be  fully  trimmed  is 92 KIAS   (gear   and   flaps   down,   propellers   at   high RPM).  Control forces produced by changes in speed, power  setting,  flap  position  and  landing  gear  position are  light  and  can  be  overcome  with  one  hand  on  the control  wheel.    Trim  tabs  permit  the  pilot  to  reduce control forces to zero.  During single-engine operation, the rudder boost system aids in relieving the relatively high    rudder    pressures    resulting    from    the    large asymmetry in power. 8A-54.  LEVEL FLIGHT CHARACTERISTICS. All flight characteristics are conventional throughout the level flight speed range. Section V.  ADVERSE ENVIRONMENTAL CONDITIONS 8A-55.  INTRODUCTION. The purpose of this section is to inform the pilot of   the   special   precautions   and   procedures   to   be followed  during  the  various  weather  conditions  that may be encountered in flight.  This section is primarily narrative;   only   those   checklists   that   cover   specific procedures  characteristic  of  weather  operations  are included.      The   checklist   in   Section   II   provides   for adverse environmental operations. 8A-56.  COLD WEATHER OPERATIONS. Operational    difficulties    may    be    encountered during extremely cold weather, unless proper steps are taken prior to or immediately after flight.  All personnel should understand and be fully aware of the necessary procedures and precautions involved. CAUTION For   ground   operations   conducive   to   ice accumulation   on   landing   gear   structure, use  undiluted  defrosting  fluid  on  brakes and  tires  to  reduce   the   tendency   of   ice accumulation    during    taxi,    takeoff,    and subsequent landing.
