A320 FCOM SUPPLEMENTARY PROCEDURES - ADVERSE WEATHER - COLD WEATHER:
EXTERIOR EXPECTION
[...]
SURFACES....CHECKED FREE OF FROST, ICE AND SNOW
All surfaces of the aircraft (critical surfaces : leading edges and upper surfaces of wings, vertical and horizontal stabilizers, all control surfaces, slats and flaps) must be clear of snow, frost and ice for takeoff.
Thin hoarfrost is acceptable on the upper surface of the fuselage.
Note: Thin hoarfrost is typically a white crystalline deposit which usually develops uniformly on exposed surfaces on cold and cloudless nights; it is so thin that a person can distinguish surface features (lines or markings) beneath it. |
