The 7 Steps to Safe Winter Flying
If you've ever driven a car during a cold winter you know the
kind of maintenance required to keep it functioning through the
snow, ice, and extreme temperatures. Small plane pilots face
similar issues during the winter months, but unlike driving a
car, winter can be the best time of the year to fly. The cold
air is denser, the engine will cool better, taking off will be
easier, you will climb steeper, and you'll be able to cruise
faster.
These key steps will enable pilots to make the most of winter
flying:
1. Pre-heat the engine
You will need extra time to prepare the plane for takeoff in the
winter. To heat the engine, either install an electric heating
element on the bottom of the crankcase or use a propane space
heater with a duct to direct hot air under the cowling. The
first solution will take about two hours, the space heater
solution about 15 minutes. It is crucial that your oil be warm
and fluid to properly lubricate the engine, even in winter. If
you attempt to fly with thick, cold oil you could quickly
destroy the engine.
2. Protect the wings and windshields from frost with cloth
covers
The accumulation of ice and snow on the plane can lead to
disaster in flight. After takeoff, ice and snow can cause the
airfoil to change shape and increase roughness. To avoid this,
keep the wings and windshields covered when the plane is at rest
so that you can simply peel them away when you're ready to fly.
If you don't have covers be sure to get all the frost off with a
push broom before flying.
3. Fill tanks after each flight
Condensation of moisture in the fuel tanks can contaminate the
fuel at any time of year and in any climate. Always fill the
tanks after flight to prevent this.
4. Break up ice on the landing gear
Slush or water on the runway can turn to ice on the landing gear
and can cause it to freeze in the up position during the flight.
To avoid this, cycle the gear a few times on ascent to keep it
free of ice.
5. Get a carbon monoxide detector for your cabin
An exhaust leak in your heater could fill the cabin with carbon
monoxide. Equipping your cabin with a detector is an affordable,
easy way to ensure the safety of you and your passengers.
6. Descend at a lower rate
In the cold, a long descent could cause the engine to cool too
much to make a go around. Descending at a lower rate with more
power will prevent this.
7. Pack winter survival gear
Always be prepared for the worst. If you crash in winter you
will need winter gear, a sleeping bag, and something to make a
fire.
