Jeppesen Stage 2 Test
Frost will disrupt the smooth flow of air over the wing, adversely affecting its lifting
capability. - ANS-How will frost on the wings of an airplane affect takeoff performance?
heat exchange - ANS-Every physical process of weather is accompanied by, or is the
result of, a
an increase in temperature as altitude is increased - ANS-A temperature inversion
would most likely result in which weather condition?
terrestrial radiation on a clear, relatively still night - ANS-The most frequent type of
ground or surface-based temperature inversion is that which is produced by
smooth air, poor visibility, fog, haze, or low clouds - ANS-Which weather conditions
should be expected beneath a low-level temperature inversion layer when the relative
humidity is high?
The temperature to which air must be cooled to be saturated. - ANS-What is meant by
the term "dewpoint"
Air temperature - ANS-The amount of water vapor which air can hold depends on the
water vapor condenses - ANS-Clouds, fog or dew will always form when
Evaporation and sublimation - ANS-What are the processes by which moisture is added
to saturated air?
The temperature of the collecting surface is at or below the dewpoint of the adjacent air
and the dewpoint is below freezing - ANS-What conditions result in the formation of
frost?
unequal heating of the Earth's surface - ANS-What causes variations in altimeter
settings between weather reporting points?
friction between the wind and the surface - ANS-The wind at 5,000 feet AGL is
southwesterly while the surface wind is southerly. This difference in direction is primarily
due to
, cool, dense air moving inland from over the water. - ANS-Convective circulation patterns
associated with sea breezes are caused by
is a temperature inversion with freezing rain at a higher altitude - ANS-The presence of
ice pellets at the surface is evidence that there
actual lapse rate - ANS-What measurement can be used to determine the stability of the
atmosphere?
warming from below - ANS-What would decrease the stability of an air mass?
stratiform clouds - ANS-What is a characteristic of stable air?
produce stratus type clouds - ANS-Moist, stable air flowing upslope can be expected to
Clouds with considerable vertical development and associated turbulence. - ANS-If an
unstable air mass is forced upward, what type of clouds can be expected?
a stable layer of air - ANS-What feature is associated with temperature inversion?
6,000 feet MSL - ANS-What is the approximate base of the cumulus clouds if the
surface air temperature at 1,000 feet MSL is 70 degreesF and the dewpoint is
48degrees F?
10,000 feet AGL - ANS-At approximately what altitude above the surface would the pilot
expect the base of cumuliform clouds if the surface air temperature is 82 degrees F and
the dewpoint is 38 degrees F?
Cumuliform clouds and showery precipitation - ANS-What are the characteristics of a
moist, unstable air mass?
turbulence and good surface visibility - ANS-What are the characteristics of unstable
air?
smooth air - ANS-A stable air mass is most likely to have which characteristic?

height range - ANS-Clouds are divided into four families according to their
