/.The general characteristics of unstable air are... - Answer-Good visibility, showery
precipitation, and cumuliform-type clouds
/.Some of the characteristics you would expect to see with an unstable air mass are... -
Answer-Turbulence and good surface visibility
/.Which are the characteristics of an unstable cold air mass moving over a warm
surface? - Answer-Cumuliform clouds, turbulence, and good visibility
/.Which is a characteristic of stable air? - Answer-Stratiform clouds
/.Which are the characteristics of stable air? - Answer-Poor visibility, steady
precipitation, and stratus-type clouds
/.Steady precipitation, in contrast to showers, preceding a front is an indication of... -
Answer-Stratiform clouds with little or no turbulence
/.Frontal waves normally form on... - Answer-Slow moving cold fronts or stationary
fronts
/.Which weather phenomenon is always associated with the passage of a frontal
system? - Answer-A wind change
/.If you fly into severe turbulence, which flight condition should you attempt to maintain?
- Answer-Level flight attitude
/.If severe turbulence is encountered during your IFR flight, the airplane should be
slowed to the design maneuvering speed because the... - Answer-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.... - Answer-Light turbulence
/.What are the requirements for the formation of a thunderstorm? - Answer-Sufficient
moisture, an unstable lapse rate, and a lifting action
, /.Which weather phenomenon signals the beginning of the mature stage of a
thunderstorm? - Answer-The start of rain at the surface
/.During the life cycle of a thunderstorm, which stage is characterized predominately by
downdrafts? - Answer-Dissipating
/.What is an indication that downdrafts have developed and the thunderstorm cell has
entered the mature stage? - Answer-Precipitation begins to fall from the cloud base
/.Where do squall lines most often develop? - Answer-Ahead of a cold front

- Answer-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? - Answer-Squall line

are obscured by massive cloud layers and cannot be seen
/.Which weather phenomenon is always associated with a thunderstorm? - Answer-
Lightning
/.Which procedure is recommended if a pilot should unintentionally penetrate embedded
thunderstorm activity? - Answer-Set power for recommended turbulence penetration
airspeed and attempt to maintain a level flight attitude
/.What is the expected duration of an individual microburst? - Answer-Seldom longer
than 15 minutes from the time the burst strikes the ground until dissipation
