EXAM 2 ASA QUESTIONS WITH
CORRECT ANSWERS
An air mass is a body of air that... - Correct Answers -Covers an extensive area and has
fairly uniform properties of temperature and moisture
The general characteristics of unstable air are... - Correct Answers -Good visibility,
showery precipitation, and cumuliform-type clouds
Some of the characteristics you would expect to see with an unstable air mass are... -
Correct Answers -Turbulence and good surface visibility
Which are the characteristics of an unstable cold air mass moving over a warm surface?
- Correct Answers -Cumuliform clouds, turbulence, and good visibility
Which is a characteristic of stable air? - Correct Answers -Stratiform clouds
Which are the characteristics of stable air? - Correct Answers -Poor visibility, steady
precipitation, and stratus-type clouds
Which is a characteristic of low-level wind shear as it relates to frontal activity? - Correct
Answers -With a warm front, the most critical period is before the front passes the
airport
Hazardous wind shear is commonly encountered near the ground... - Correct Answers -
During periods of strong temperature inversion and strong thunderstorm
Where can wind shear associated with a thunderstorm be found? Choose the most
complete answer - Correct Answers -On all side of the thunderstorm cell and directly
under the cell
Steady precipitation, in contrast to showers, preceding a front is an indication of... -
Correct Answers -Stratiform clouds with little or no turbulence
Frontal waves normally form on... - Correct Answers -Slow moving cold fronts or
stationary fronts
Which weather phenomenon is always associated with the passage of a frontal system?
- Correct Answers -A wind change
, If you fly into severe turbulence, which flight condition should you attempt to maintain? -
Correct 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... - Correct 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.... - Correct Answers -Light turbulence
What are the requirements for the formation of a thunderstorm? - Correct Answers -
Sufficient moisture, an unstable lapse rate, and a lifting action
Which weather phenomenon signals the beginning of the mature stage of a
thunderstorm? - Correct Answers -The start of rain at the surface
During the life cycle of a thunderstorm, which stage is characterized predominately by
downdrafts? - Correct Answers -Dissipating
What is an indication that downdrafts have developed and the thunderstorm cell has
entered the mature stage? - Correct Answers -Precipitation begins to fall from the cloud
base
Where do squall lines most often develop? - Correct Answers -Ahead of a cold front
If squalls are reported at your destination, what wind conditions should you anticipate? -
Correct 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? - Correct Answers -Squall line
What is indicated by the term "embedded thunderstorms"? - Correct Answers -
Thunderstorms are obscured by massive cloud layers and cannot be seen
Which weather phenomenon is always associated with a thunderstorm? - Correct
Answers -Lightning
Which procedure is recommended if a pilot should unintentionally penetrate embedded
thunderstorm activity? - Correct Answers -Set power for recommended turbulence
penetration airspeed and attempt to maintain a level flight attitude
What is the expected duration of an individual microburst? - Correct Answers -Seldom
longer than 15 minutes from the time the burst strikes the ground until dissipation
