winter operations Flashcards
During pre-flight of a snow covered aircraft the Probe/Window heat should not be selected because
Melted snow could re-freeze in front of the pitot tubes and disturb the airflow
If taxyiing in CAVOK conditions with the temperature at -1°C degree and with taxiways contaminated with slush or snow
Engine anti-icing should be on
If the night time visibility in snowfall is 1 statue mile and the Airport temperature is -3°C
The snowfall is intensity is moderate
Approach speed increments should be applied
If there is evidence of ice accretion on de-iced parts (WING ANTI ICE inoperative) of the airframe
Icing conditions are severe when there is approximately
5mm of ice on the airframe
Type II fluid, 75/25 mix, OAT -3°C, light freezing rain. The holdover time is?
10-25 minutes, with no visual check required prior to take-off provided the holdover times have not been exceeded
When enroute and icing conditions at destination are confirmed to require de/anti-icing and no de/anti-icing equipment is available:
A decision to divert or continue should be made after consultation with IOC
If taxyiing in icing conditions with precipitation on runways and taxiways contaminated with slush or snow, once the flap/slat mechanism is free of contamination, the flaps/slats may be retracted by using the relevant procedure before the electrical network is de-energized
Monitor retraction on the ECAM page
Clean concept means
Dragonair aircraft shall not take off when ice, snow, slush or frost is present on, or adhering to wings, control surfaces, engine inlets or other critical surfaces
During pre-flight of a snow covered aircraft the Probe/Window heat should not be selected on because
Melted snow could re-freeze in front of the pitot tubes and disturb the airflow
For heavy precipitation use
No holdover times exist
