ATC Weather Exam Questions And Answers
|Latest 2025 | Guaranteed Pass.
Atmospheric Pressure - Answer✔The force exerted by the atmosphere at a given point.
(At sea level) Surface temperature? - Answer✔15 Degrees C/59 Degrees F
(At sea level) Surface pressure? - Answer✔29.92 inches of mercury
Weight of atmosphere at sea level... - Answer✔14.7 pounds per square inch
Pressure decreases roughly how much of mercury for each 1,000 feet increase in altitude? -
Answer✔One inch
Aneroid Barometer - Answer✔Less accurate than the mercurial barometer.
Altimeter Settings Indicator (ASI) - Answer✔Primary means of obtaining altimeter settings at
terminal facilities, DASI is Digital.
Station Pressure - Answer✔Pressure measured at airport.
AGL - Answer✔Above ground level
MSL - Answer✔Mean sea level
True Altitude - Answer✔an actual or exact altitude above mean sea level.
Indicated Altitude - Answer✔an altitude above mean sea level indicated on the altimeter.
Aircraft flies from a high pressure area to a low pressure area, the aircraft is _____ than the
altimeter indicates. - Answer✔Lower.
Aircraft flies from a low pressure area to a high pressure area, the aircraft is _____ than the
altimeter indicates. - Answer✔Higher.
Define Lapse Rate. - Answer✔When temperature decreases with an increase in altitude.
Standard Lapse Rate - Answer✔2 Degrees C/3.3 Degrees F per 1,000 feet
Aircraft flying from warm to cold air, the aircraft will be _____ than the altimeter indicates. -

Aircraft flying from cold to warm air, the aircraft will be _____ than the altimeter indicates. -
Answer✔Higher; "Low to high, eyes to the sky."
Pressure Altitude - Answer✔The altitude in the standard atmosphere where the current
pressure surrounding the aircraft is found.
FAA regulations require aircraft to fly at pressure altitudes at high levels. What is the example
given to us? - Answer✔Above 18,000 feet, automatically input 29.92.
Density Altitude - Answer✔The altitude in the standard atmosphere where density of the air
surrounding the aircraft is found.
What determines air density? - Answer✔Pressure, temperature, and humidity.
What happens in high density altitude and how does it effect an aircraft? - Answer✔Hot day, air
becomes "thinner" and "lighter." Reduces aircraft performance by reducing power, thrust, and
lift and lengthens takeoff and landing role. Reduces the rate of climb.
What does low density do? - Answer✔Increases aircraft performance.
Convective Current - Answer✔Caused by two surfaces heated unequally cause the uneven
heating of the air above.
Wind - Answer✔The horizontal airflow in a convective current
Advection - Answer✔Horizontal movement of wind.
Air flows from areas of _____ pressure to ares of _____ pressure. - Answer✔Higher; lower.
Atmospheric circulation is... - Answer✔a convective current occurring on a large scale.
Jet stream - Answer✔A narrow band of strong winds moving through the upper atmosphere.
The jet stream is _____ in altitude in the winter. - Answer✔Lower.
The jet stream is _____ in altitude in the summer. - Answer✔Higher.
The jet stream creates high-level wind shear/... - Answer✔Clear Air Turbulence (CAT).
Isobars - Answer✔Lines drawn on weather maps to connect points of equal pressure, used to
plot and identify organized pressure points at sea level.
Low Pressure Areas on Isobars - Answer✔Wind flow around the system is counterclockwise
(cyclonic).
Unfavorable Flying Conditions - Answer✔Strong, Gusty winds, Turbulence, Low clouds, and
Restricted visibility due to precipitation (STLR).
High Pressure Areas on Isobars - Answer✔Wind flow is clockwise (anticyclonic).
