Definition of Icing conditions
Icing conditions exist when the SAT on the ground and for take-off is 10°C or below, or SAT in flight is 5°C or below, and visible moisture in any form is present (such as clouds, fog with visibility of one mile or less, rain, snow, sleet, or ice crystals). Icing conditions also exist when the SAT on the ground and for take-off is 10°C or below when operating on ramps, taxiways or runways where surface snow, ice, standing water, or slush may be ingested by the engines or freeze on engines, nacelles or engine sensor probes.
Limitation for use of HF
With HF Comm installed, use of the HF transmitter is prohibited when the ADF is used as the prime means of navigation or for position confirmation.
