LEAVING THE AIRPLANE - SECURING FOR COLD SOAK OR AN
EXTENDED PERIOD
The procedures below should be performed in the event of extended
airplane exposure at low temperatures. In the event that the airplane is
off the maintenance base, the crew should ensure that all actions have
been accomplished.
Wheel Chocks........................................IN PLACE
Emergency/Parking Brakes ...................AS REQUIRED
For an icy ramp, leave Emergency/Parking Brakes applied.
Otherwise, Emergency/Parking Brakes must not be applied to
avoid freezing of the brakes.
Pitch Trim ..............................................FULL NOSE DOWN
As high precipitation may occur during overnights, it is
recommended that pitch trim be left at full nose down position.
Gust Lock...............................................LOCKED
Protective Covers...................................INSTALLED
Install protective covers at engines and APU inlets/outlets, pitot,
TAT probes, and wheels.
Water and Waste System ......................DRAINED
Drain water and waste from all water tanks, if cold soak
temperature is expected to be below 0°C (32°F).
Batteries.................................................REMOVED
As the batteries may not fully recharge under very low
temperatures, batteries should be removed whenever the
temperature forecast during the overnight is below -15°C (5°F).
Doors and Windows...............................CLOSED
All doors and windows must be closed to prevent snow and
humidity from entering into the airplane.
