Cold Weather Operation
Special consideration should be given to the operation of the airplane fuel
system during the winter season or prior to any flight in cold temperatures.
Proper preflight draining of the fuel system is especially important and will
eliminate any free water accumulation.
Cold weather often causes conditions which require special care during
airplane operations. Even small accumulations of frost, ice or snow must be
removed from wings, tail and control surfaces (external and internal) to
assure satisfactory flight performance and handling.
Cold Weather Starting
Prior to starting on cold mornings, it is advisable to pull the propeller through
several times by hand to "break loose" or "limber the oil.
{ CAUTION }
Before Pulling Prop Through, Verify the Magneto Switch is OFF
