 Shergood helicopters are certified for use with Type 1 and Type 3 deicing fluids.  When using a Type 3 fluid, it is recommended that the pilot achieve a forward speed of at least 60 knots before leaving ground effect.

 ===== Deicing =====
-Deicing can be used to remove ice already present on an aircraft while it is on the ground.  This is accomplished through the use if deicing fluids.
+Ground deicing should be performed before flight to remove any ice adhering to aircraft surfaces and/or provide ice protection during ground operations.  This is normally performed through the use of deicing fluids applied to the aircraft.  Deicing fluids come in a variety of types as described in the table below.

 * Blocking engine air intakes and/or carburetors potentially resulting in loss of power
-Ice is most common when outside air temperature is between -10C and 0C, and visible moisture is present either through precipitation or high humidity.  Below -10C, any moisture present is generally already frozen and does not pose a danger in adhering to the aircraft.

-This section describes the weather as generated by the Shergood SL Weather simulator.  While intended to mimic many of the features of RL weather, it is a simplified model and does not include all the effects of RL weather.  The simulator is based on conditions at mid-latitudes in the Northern Hemisphere of RL Earth.  The results in Weather systems that generally move West to East, and winds that generally rotate counter-clockwise around low pressure systems.
