Aviation Weather PPL questions and answers with 100% correct
solutions
1. Thunderstorms which generally Squall line thunderstorms
produce the most intense hazard
to aircraft are?
2. What are the processes by which moisture Evaporation and sublimation
is added to unsaturated air?
3. Why is frost considered Frost spoils the smooth flow of air over
hazardous to flight? the wings, and therefore decreases the
lift capa- bility of an aircraft
4. Clouds, fog, or dew will always form when Water vapor condenses
5. Clouds are divided into four families 10. When may hazardous
ac- cording to their wind shear be ex-
pected?
6. Crests of standing mountain waves
may be marked by stationary,
lens-shaped clouds known as?
7. which conditions result in the
formation of frost?
8. the temperature of the collecting
surface is at or below the dewpoint of
the adjacent air and the dewpoint is
below freezing
9. a pilot can expect a wind-shear
zone in a temperature inversion
whenever the
windspeed at 2,000-4,000 feet
above the surface is at least
