TM 1-1510-224-10 g. Landing.  Extreme care must be exercised when landing  on  ice  or  slippery  runways.    Excessive  use  of either  brakes  or  power  may  result  in  an  uncontrollable skid.  Ice accumulation on the aircraft will result in higher stalling   airspeeds   due   to   the   change   in   aerodynamic characteristics  and  increased  weight  of  the  aircraft  due to ice buildup.  Approach and landing airspeeds must be increased accordingly. 8-52.  SEVERE ICING. a. The     following     weather     conditions     may     be conducive to severe in-flight icing: (1) Visible   rain   at   temperatures   below   zero degrees Celsius ambient air temperature. (2) Droplets  that  splash  or  splatter  on  impact at temperatures below zero degrees Celsius ambient air temperature. b. The   following   procedures   for   exiting   a   severe icing environment are applicable to all flight phases from takeoff to landing. (1) Monitor     the     ambient     air     temperature. While severe icing may form at temperatures as cold as –18 degrees Celsius, increased vigilance is warranted at temperatures    around    freezing    with    visible    moisture present. (2) Upon  observing  the  visual  cues  specified in     the     limitations     section     of     this     manual     for     the identification     of     severe     icing     conditions     (reference paragraph 5-34), accomplish the following: (a) Immediately request priority handling  from  air  traffic  control  to  facilitate  a  route  or  an altitude   change   to   exit   the   severe   icing   conditions   in order   to   avoid   extended   exposure   to   flight   conditions more  severe  than  those  for  which  the  aircraft  has  been certificated. (b) Avoid abrupt and excessive maneuvering that may exacerbate control difficulties. (c) Do not engage the autopilot. (d) If  the  autopilot  is  engaged,  hold  the control wheel firmly and disengage the autopilot. (e) If     an     unusual     roll     response or uncommanded roll control movement is observed reduce the angle-of-attack. (f) Do not extend flaps during extended operation   in   icing   conditions.      Operations   with   flaps extended  can  result  in  a  reduced  angle-of-attack,  with the possibility of ice forming on the upper surface further aft on the wing than normal, possibly aft of the protected area. (g) If   the   flaps   are   extended,   do   not retract them until the airframe is clear of ice. (h) Report  these  weather  conditions  to air traffic control. Section VI.  CREW DUTIES. *8-53.  DEPARTURE BRIEFING. NOTE The   aircraft   incorporates   advanced technologies   in   regard   to   ASE/ACS and  EFIS  systems.    Aviators  should conduct thorough crew briefings prior   to   departures   and   arrivals   to ensure    that    systems    are    set    and understood. The   following   is   a   guide   that   should   be   used   as applicable  in  accomplishing  the  required  crew  briefing prior   to   takeoff;   however,   if   the   crew   has   operated together  previously  (thru-flight)  and  the  pilot  is  certain that  the  copilot  understands  all  items  of  the  briefing,  the pilot  may  omit  the  briefing  by  stating  "standard  briefing" when   the   briefing   is   called   for   during   the   BEFORE TAKEOFF CHECK. 1.
