Visually check airplane for general condition during walk-around
inspection. In cold weather, remove even small accumulation of frost, ice
or snow from wing, tail and control surfaces. Also, make sure that control
surfaces contain no internal accumulation of ice or debris. Prior to flight,
check that pitot heater (if installed) is warm to touch within 30 seconds
with battery and pitot heat switches on. If a night flight is planned, check
operation of all lights, and make sure a flashlight is available.
