Exam 2 ASA Questions8
An air mass is a body of air that... - ANSWERS-Covers an extensive area and has fairly uniform
properties of temperature and moisture
The general characteristics of unstable air are... - ANSWERS-Good visibility, showery
precipitation, and cumuliform-type clouds
Some of the characteristics you would expect to see with an unstable air mass are... - ANSWERS-
Turbulence and good surface visibility
Which are the characteristics of an unstable cold air mass moving over a warm surface? -
ANSWERS-Cumuliform clouds, turbulence, and good visibility
Which is a characteristic of stable air? - ANSWERS-Stratiform clouds
Which are the characteristics of stable air? - ANSWERS-Poor visibility, steady precipitation, and
stratus-type clouds
Steady precipitation, in contrast to showers, preceding a front is an indication of... - ANSWERS-
Stratiform clouds with little or no turbulence
Frontal waves normally form on... - ANSWERS-Slow moving cold fronts or stationary fronts
Which weather phenomenon is always associated with the passage of a frontal system? -
ANSWERS-A wind change
, If you fly into severe turbulence, which flight condition should you attempt to maintain? -
ANSWERS-Level flight attitude
If severe turbulence is encountered during your IFR flight, the airplane should be slowed to the
design maneuvering speed because the... - ANSWERS-Amount of excess load that can be
imposed on the wing will be decreased
A pilot reporting turbulence that momentarily causes slight, erratic changes in altitude and/or
attitude should report it as a.... - ANSWERS-Light turbulence
What are the requirements for the formation of a thunderstorm? - ANSWERS-Sufficient
moisture, an unstable lapse rate, and a lifting action
Which weather phenomenon signals the beginning of the mature stage of a thunderstorm? -
ANSWERS-The start of rain at the surface
During the life cycle of a thunderstorm, which stage is characterized predominately by
downdrafts? - ANSWERS-Dissipating
What is an indication that downdrafts have developed and the thunderstorm cell has entered
the mature stage? - ANSWERS-Precipitation begins to fall from the cloud base
Where do squall lines most often develop? - ANSWERS-Ahead of a cold front
If squalls are reported at your destination, what wind conditions should you anticipate? -
ANSWERS-Sudden increases in wind speed of at least 16 knots, rising to 22 knots or more,
lasting for at least one minute
Which thunderstorm generally produce the most severe conditions, such as heavy hail and
destructive winds? - ANSWERS-Squall line
