11- At temperatures of between 0oC and -10oC clouds consist of:
- AEntirely water droplets.
- BEntirely ice crystals.
- CMostly water vapour.
- DMostly supercooled water droplets and a few ice crystals.
22- Turbulent clouds are most serious from the icing standpoint because:
- AStrong vertical currents mean that a predominance of large supercooled water droplets will be present.
- BStrong vertical currents mean that a predominance of small supercooled water droplets will be present.
- CTurbulent clouds produce hail which sticks to the aircraft.
- DTurbulent clouds indicate a low freezing level.
33- Hoar frost forms on an aircraft when:
- AThe aircraft suddenly enters a cloud at below freezing temperature.
- Bhe aircraft in sub zero clear air suddenly enters a colder region.
- CThe aircraft in sub zero clear air suddenly enters a warmer moist
region. - DThe aircraft suddenly enters a cloud which is at higher temperature than the surrounding air.
44- Stratus cloud of limited depth at a temperature of -5o C will most likely give:
- AModerate to heavy rime ice.
- BModerate to heavy glaze ice.
- CLight to moderate rime ice.
- DLight to moderate glaze ice.
55- Most cases of serious piston engine icing occur in cloud, fog, or precipitation with a temperature range between:
- A- 10ºC to +25ºC
- B-18ºC to +5ºC
- C-10ºC to 0ºC
- D-20ºC to +15ºC
66- Clear ice forms as a result of:
- ALarge supercooled water droplets spreading as they freeze.
- BIce pellets splattering on the aircraft.
- CSmall supercooled water droplets splashing over the aircraft.
- DWater vapur freezing to the aircraft.
77- Orographic uplift in stable conditions gives a strong vertical component to air movement thus supporting larger supercooled droplets in orographically formed cloud. Consideration should also be given to the fact that in this cloud:
- AThe 0ºC isotherm will be higher.
- BThe 0ºC isotherm will be lower.
- CThe lapse rate will be isothermal.
- DAn inversion can be anti-cyclonic.
88- Carburettor icing is unlikely:
- AIn cloud.
- BAt temperatures between -10oC and -30oC.
- CIn clear air.
- DWhen the RH is 60%.
99- Flying 50 nm ahead of a warm front out of cloud at 1000 ft in winter, with an ambient temperature of -8oC, there is a strong risk of:
- AHoar frost.
- BRime icing and carburettor icing.
- CStructure damage caused by hail.
- DClear ice in the form of rain ice.
1010- In AS cloud at FL 170 and a temperature of -20oC the airframe icing most likely to be experienced is:
- AModerate clear icing.
- BLight rime icing.
- CHoar frost.
- DSevere clear icing.
