Aviation Weather (PPL questions)
with Correct Answers
Thunderstorms which generally produce the most intense hazard to aircraft are? -
ANSWER✔✔-Squall line thunderstorms
What are the processes by which moisture is added to unsaturated air? - ANSWER✔✔-
Evaporation and sublimation
Why is frost considered hazardous to flight? - ANSWER✔✔-Frost spoils the smooth
flow of air over the wings, and therefore decreases the lift capability of an aircraft
Clouds, fog, or dew will always form when - ANSWER✔✔-Water vapor condenses
Clouds are divided into four families according to their - ANSWER✔✔-Height range
Crests of standing mountain waves may be marked by stationary, lens-shaped clouds
known as? - ANSWER✔✔-standing lenticular clouds
which conditions result in the formation of frost? - ANSWER✔✔-the temperature of the
collecting surface is at or below the dewpoint of the adjacent air and the dewpoint is
below freezing

, the temperature of the collecting surface is at or below the dewpoint of the adjacent air
and the dewpoint is below freezing - ANSWER✔✔-stratiform clouds
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 - ANSWER✔✔-25 knots
When may hazardous wind shear be expected? - ANSWER✔✔-in areas of low-level
temperature inversion, frontal zones, and clear air turbulence
low-level turbulence can occur and icing can become hazardous in which type of fog? -
ANSWER✔✔-steam fog
steady precipitation preceding a front is an indication of? - ANSWER✔✔-stratiform
clouds with little or no turbulence
where does wind shear occur? - ANSWER✔✔-at all altitudes, in all directions
what situation is most conducive to the formation of radiation fog? - ANSWER✔✔-
warm, moist air over low, flatland areas on clear, clam nights
how does frost affect the lifting surfaces of an airplane on takeoff? - ANSWER✔✔-frost
will disrupt the smooth flow of air over the wing, adversely affecting its lifting
capability
convective circulation patters associated with sea breezes are caused by - ANSWER✔✔-
cool, dense air moving inland over the water
