Worksheet time: 13mins
Weather phenomena, such as clouds and precipitation, could be caused by which of these? (1.A.1)
Proximity to mountains
Proximity to oceans
Movement of an air mass
All of the above
The atmosphere is best described as __________ that surrounds the earth. (1.B.1)
a blanket of air and precipitation
an envelope of gases
a stream of clouds
a cushion of hot and cold air
Fog is formed when the air just above the ground cools to the dew point, causing the air to __. (1.B.3)
rise and then expand
become saturated with moisture
Become precipitous
condense and become a cloud
Which condition is most likely to cause turbulence during flight? (1.A.1)
Precipitation
Wind
Humidity
Clouds
As the continental polar air mass moves over warm water, __________. (1.B.4)
it could produce clouds and drizzle
it could become unstable and create rain showers
the air near the surface will become warmer and gain moisture
it tends to be very stable with fog or little precipitation
Jets typically fly at the top of the troposphere where the air is the coolest. Why do jets operate only in the troposphere, even though they are often capable of climbing higher? (1.B.1)
Jet engines run efficiently in the exact temperature at the top of the troposphere; navigation tools are inoperable above the troposphere.
The cool air at the top of the troposphere helps jet engines to run efficiently; operating above the troposphere could interfere with satellite data.
Jet engines run efficiently in the exact temperature at the top of the troposphere; cooler temperatures could cause engine failure.
The cool air at the top of the troposphere helps jet engines to run efficiently; the air is not cooler above the troposphere.
The intensities of turbulence are called light, moderate, severe, and __________. (1.B.5)
dense
extreme
heavy
dangerous
As an airplane starts entering a microburst, performance increases. (1.B.5)
True
False
What is the basic cause of all weather? (1.B.2)
Clouds and precipitation
Wind pushing against low pressure areas
Uneven heating of the earth's surface
Ocean and land interactions
Virga is rain that evaporates prior to reaching the ground and may precede__________. (1.B.3)
a warm air layer
sleet
snow
a microburst
Wind may have a variety of effects on an aircraft. Select all the ways wind may affect a flight. (1.A.1)
Wind may cause turbulence.
A tailwind may increase an aircraft’s speed across the ground.
A strong headwind can result in an aircraft using more fuel in flight compared to the same flight with no wind.
Wind changes affect the effectiveness of aircraft controls.
Towering cumulonimbus with strong weather is a likely indication of__________. (1.B.4)
a stationary front
an occluded front
a cold front
a warm front
What kind of information would you receive from a radar image? (2.A.1)
Wind speed and direction
Cloud cover
Precipitation intensity
Atmospheric pressure
A weather report predicts what the weather will be at a future point in time. (2.A.1)
True
False
Weather forecasts are often based on complex mathematical models. They may take hundreds of thousands of variables into account, sometimes causing forecasts to be__________. (2.A.1)
difficult to interpret
inaccurate
overly detailed
slow in response
