Aviation Weather Exam Solved
Questions With Revised Correct
Detailed Answers >> BRAND NEW
VERSION!!
How do you determine if you can fly locally? - Answer- Check METAR, TAF, Radar
Forecast, NOTAMs
How do you determine if you can fly cross country? - Answer- Review all the charts on
aviation weather and 1800WXBrief
What is IFR, MVFR, and VFR? - Answer- IFR weather means ceilings less than 1,000'
and visibility less than 3 statute miles. MVFR means ceilings between 1,000-3,000' and
visibility 3-5 statute miles. VFR means ceilings greater than 3,000' and visibility greater
than 5 miles.
What are the weather minimums for VFR pilots? What about IFR pilots? - Answer- If
you are a private pilot you have to follow the rules of VFR. If you are an instrument pilot,
you can take off even if the weather is 0' ceilings and 0' visibility.
What is an airmet? - Answer- Airmet Sierra - ifr and mountain obscuration
Airmet Tango - turbulence, wind shear
Airmet Zulu - icing
What is a sigmet? - Answer- severe icing
severe turbulence
volcanic ash or dust
What is a convective sigmet? - Answer- Convective SIGMET
-55 minutes past the hour and valid for 2 hours. -Line of thunderstorms
-Embedded thunderstorms
-Wide area of thunderstorms
-Severe thunderstorms characterized by wind in excess of 50 kias, hail 3/4" diameter or
greater, or tornadoes
How do you contact a flight service station? - Answer- Tune to 122.2 or tune to an RCO
and state who you are, where you are, 'receiving hampton vor' if that's what you are
doing, and what you want
Of the heat that reaches earth, how much gets reflected and how much gets absorbed?
- Answer- "Of the heat that reaches earth, 55% gets reflected and 45% gets absorbed"
, What is diurnal temperature variation? - Answer- Diurnal temperature variation is the
difference in temperature between day and night.
What is the affect of high temperature on air density? - Answer- High temperature
reduces air density and performance
What creates local wind? - Answer- Diurnal and topographical temperature variations
create local wind
What is an effect of diurnal cooling? - Answer- Diurnal cooling is conducive to fog
What type of dangerous precipitation can be caused by a temperature inversion? -
Answer- An inversion aloft can cause rain to turn into freezing rain
What problems can result from a ground based inversion? - Answer- A ground based
inversion favors poor visibility by trapping haze, fog, and smoke at low altitudes
Who invented the barometer? - Answer- Toricelli invented the barometer
What is 'hg'? - Answer- Hg is the abbreviation for millibars
What is pressure altitude? - Answer- Pressure altitude - set the altimeter to 29.92
What is corrected altitude? - Answer- Corrected altitude - indicated altitude corrected for
temperature
What is indicated altitude? - Answer- indicated altitude - the pressure seen on the
altimeter when set at the local altimeter setting
What is true altitude? - Answer- True altitude - height above sea level
What is absolute altitude? - Answer- Absolute altitude - height above the ground
What is density altitude? - Answer- Density altitude - pressure altitude corrected for non-
standard temperature (the density altitude in the standard atmosphere where the air
density is the same as where you are)
How does a pressure gradient relate to wind? - Answer- The greater the difference
between pressure gradients the stronger the wind
What is the affect of the Coriolis force in the northern hemisphere? - Answer- The
Coriolis force deflects air to the right in the northern hemisphere
What slows the wind? - Answer- Friction between the wind and the surface?
