Aviation Weather Exam 1 Questions And
Answers Latest Update | Solved
78% CORRECT ANSWERS What percentage of atmosphere is Nitrogen?
Advection CORRECT ANSWERS Transferring energy from Canada to the US is called -
Nitrogen CORRECT ANSWERS Of all the gasses in the atmosphere, which does not
play a vital role in weather?
Carbon Dioxide CORRECT ANSWERS Which gas absorbs terrestrial radiation?
Pressure, Temperature, Density CORRECT ANSWERS The atmosphere is always
constant. (R) What are the three things that do change to maintain the always equal 'R'
variable?
Density CORRECT ANSWERS Amount of air molecules in a given area?
Approx. 160,000 feet CORRECT ANSWERS How high up does the atmosphere
extend?
18,000 feet CORRECT ANSWERS 1/2 of the atmosphere exists under what altitude?
Troposphere CORRECT ANSWERS Which layer of the Earth's atmosphere does most
weather occur?
Stratosphere and Thermosphere CORRECT ANSWERS Which two layers of the Earth's
atmosphere does the temperature get warmer, the higher you go?
Electromagnetic Radiation CORRECT ANSWERS What is sent towards us from the
sun?
Radiation CORRECT ANSWERS Transfer of energy from the sun would be what
process?
Ozone CORRECT ANSWERS What element in the atmosphere is fairly constant for
time of year or latitude, and helps determine how much radiation we get?
Lower solar elevation angle CORRECT ANSWERS Why in the northern parts of the
world does it stay colder longer and have greater variations in temperature?
False - equinox CORRECT ANSWERS True or False - Noon on the first day of spring
and fall is the vernal and autumnal solstice?
, 30% CORRECT ANSWERS What percentage of incoming solar radiation is sent back
into space?
66.5% CORRECT ANSWERS Above or below what latitude does the sun not rise one
day a year?
14.7 lbs CORRECT ANSWERS If you measure the pressure of a one inch, square
scale at sea level, what would that scale read?
Indicated - Directly what the gauge reads on the faceplate.
Pressure - Gauge difference set to 29.92 inHg
True - Altitude measured in MSL
Density - Pressure altitude corrected for nonstandard temperatures CORRECT
ANSWERS What are the following altitudes: Indicated Altitude, Pressure Altitude, True
Altitude, and Density Altitude?
Altimeter settings are corrected to sea level at standard temperature. CORRECT
ANSWERS Why would an altimeter setting of 29.92 in New Orleans, LA be the same
value as the same altimeter setting in Denver, CO?
Density Altitude CORRECT ANSWERS An airport is at 1150' MSL, and it is 85 degrees
F. Airplanes will perform less efficiently. What is the difference between actual runway
elevation and corrected pressure?
Outlook. 6 hours before a flight. CORRECT ANSWERS What is the first weather
briefing to get done before a flight? When can you get one?
Land cools down creating high pressure at night, and lower pressure over the sea. The
air moves out over the low pressure of water. The opposite occurs in the daytime as the
land heats up due to the suns radiation being reflected. CORRECT ANSWERS What
causes air to move from the land out to the ocean?
Hourly, with SPECI's as they are needed. CORRECT ANSWERS How often does a
METAR come out?
Visibility is less than 3 SM, wind shift at least 60 degrees in 15 minutes, or other severe
weather advisories CORRECT ANSWERS What are some reasons for a SPECI report?
The most intense; the sleet CORRECT ANSWERS If there was moderate sleet and light
freezing rain, which would show up in a METAR?
Vertical Visibility at 100'; indefinite ceiling CORRECT ANSWERS On a METAR, what
would VV001 mean?
Abbreviated Briefing CORRECT ANSWERS After an Outlook and Standard weather
briefing, what would you need next?
