stage 3 study Flashcards
What are characteristics of a moist, unstable air mass?
Cumuliform clouds and showery precipitation.
What would decrease the stability of an air mass?
Warming from below.
Which inflight advisory would contain information on severe icing not associated with thunderstorms?
SIGMET.
Which conditions result in the formation of frost?
The temperature of the collecting surface is at or below the dew point of the adjacent air and the dew point is below freezing.
If the temperature/dew point spread is small and decreasing, and the temperature is 62°F, what type weather is most likely to develop?
Fog or low clouds.
Steady precipitation preceding a front is an indication of
stratiform clouds with little or no turbulence.
What feature is associated with a temperature inversion?
A stable layer of air.
What is the approximate base of the cumulus clouds if the surface air temperature at 1,000 feet MSL is 70°F and the dew point is 48°F?
6,000 feet MSL.
Clouds, fog, or dew will always form when
water vapor condenses.
What clouds have the greatest turbulence?
Cumulonimbus.
When the course deviation indicator (CDI) needle is centered during an omnireceiver check using a VOR test signal (VOT), the omnibearing selector (OBS) and the TO/FROM indicator should read
0° FROM or 180° TO, regardless of the pilot’s position from the VOT.
