Q

During pre-flight of a snow covered aircraft the Probe/Window heat should not be selected because

A

Melted snow could re-freeze in front of the pitot tubes and disturb the airflow

1
Q

If taxyiing in CAVOK conditions with the temperature at -1°C degree and with taxiways contaminated with slush or snow

A

Engine anti-icing should be on

2
Q

If the night time visibility in snowfall is 1 statue mile and the Airport temperature is -3°C

A

The snowfall is intensity is moderate

3
Q

Approach speed increments should be applied

A

If there is evidence of ice accretion on de-iced parts (WING ANTI ICE inoperative) of the airframe

4
Q

Icing conditions are severe when there is approximately

A

5mm of ice on the airframe

5
Q

Type II fluid, 75/25 mix, OAT -3°C, light freezing rain. The holdover time is?

A

10-25 minutes, with no visual check required prior to take-off provided the holdover times have not been exceeded

6
Q

When enroute and icing conditions at destination are confirmed to require de/anti-icing and no de/anti-icing equipment is available:

A

A decision to divert or continue should be made after consultation with IOC

7
Q

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

A

Monitor retraction on the ECAM page

8
Q

Clean concept means

A

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

9
Q

During pre-flight of a snow covered aircraft the Probe/Window heat should not be selected on because

A

Melted snow could re-freeze in front of the pitot tubes and disturb the airflow

10
Q

For heavy precipitation use

A

No holdover times exist
