Fuel consumption on take off will be significantly increased B. It will not affect performance C. It could seriously affect performance (all ice must be removed before flight) D. It could freeze the elevators, but take off would still be safe 6. From stratus, the most likely type of precipitation is: A. Heavy continuous rain B. Snow showers C. Drizzle D.

Inside the clouds D. In the top 1000`of the CU 8. Clear icing is most likely to occur: A. In ST at the freezing level B. In the clear air below fog C. In SC when it is very cold D. In CU with the temperature just below freezing 9. With a small increase in wind strength, radiation fog can deepen because A. Cold air near he ground will be mixed to a greater depth B. Extra moisture is brought in by the increasing wind C. There is always a drop in temperature when the wind speed increases D. It blows the fog towards colder ground 10. What is the most likely result in a moist airflow over a mountain range? A. A lower cloud base on the leeward slope B. A lower cloud base on the windward slope C. More cloud on the lee slope D. Cloud base same on both sides 11. Clear ice is most likely to be severe in which temperature range: A. +10oC to +5oC B. +5oC to 0o C C. 0o C to -15oC D. -15oC to -30oC 12.

Thunderstorms in a cold front are potentially more dangerous to aircraft than airmass thunderstorms because: A. They are slower moving and therefore hang around B. Usually there are numerous storms very close together along a frontal line C. There is little warning of their formation D. Because they are colder and thus have a greater vertical development 14.
