COLD WEATHER OPERATIONS

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. The use of
additives such as isopropyl alcohol or Diethylene Glycol Monomethyl
Ether (DIEGME) may also be desirable. Refer to Section 8, Fuel
Additives, for more information on the proper use of fuel additives.
Cold weather often causes conditions that require special care during
airplane operations. Even small accumulations of frost, ice, or snow
must be removed, particularly from wing, tail and all control
surfaces to assure satisfactory flight performance and handling.
Also, control surfaces must be free of any internal accumulations of ice
or snow.
If snow or slush covers the takeoff surface, allowance must be made for
takeoff distances which will be increasingly extended as the snow or
slush depth increases. The depth and consistency of this cover can, in
fact, prevent takeoff in many instances.
The Garmin G300 Instrumentation Liquid Crystal Displays (LCD) may
acquire a frosted or cloudy appearance at extremely cold temperatures.
The displays may also be very slow to update information when cold
soaked. Proper flight display clarity and flight data update rates may
require extended warm-up.
The Garmin G300 EIS engine information is recommended for engine
start due to possibility of engine damage resulting from inability to
monitor engine upon start.
Takeoff is not recommended until displays are clearly legible and
information updates (as indicated by heading change during taxi, RPM
changes with throttle, etc) are shown in real-time without hesitation.
The Garmin G300 display warm-up is best accomplished by placing the
airplane in a warm hangar and leaving the cabin doors open. If a
hangar is not available, attach External Power (if installed) and set the
MASTER Switch (BAT) and AVN MASTER Switch to the ON position.
Allow display units to warm internally until legible and display controls
(softkeys and knob) function normally when operated.
