reconmended to carry out the following basic operations:
-Remove ice or snow deposits from the whole of the aircraft, particularly
at hinges and movement transmitting items (main rotor, rotor mast, tail
drive and tail rotor, flight controls, engine controls).
.
-When the aircraft has been subjected to very low temperatures, it is
recOlmlended that:
-.either reaular around runs be carried out every two hours for
temperatures of about -20.C or every hour for lower temperatures.
.or preheatina of the engine, transmission assemblies and cabin be
effected before take-off (although the helicopter is capable of
carrying out engine start up and rotor spinning at temperatures down
to -40'C) (See Daily operating checks in cold weather).
