AGI - Weather and Weather
Services Exam 2025 Questions and
Answers 100% Pass
In what part of the atmosphere does most weather occur? - ✔✔Troposhere.
Which is the primary driving force of weather on the earth? - ✔✔The sun.
What are the standard temperature and pressure values for mean sea level? - ✔✔59
degrees F and 1013.2 mb. (15 degrees C)
The average lapse rate in the troposphere is - ✔✔2.0 degrees C per 1,000 feet.
If the air temperature is +6 degrees C at an elevation of 700 feet and a standard
(average) temperature lapse rate exists, what will be the approximate freezing level? -
✔✔3,700 feet MSL.
If the air temperature is +12 degrees C at an elevation of 1,250 feet and a standard
(average) temperature lapse rate exists, what will be the approximate freezing level? -
✔✔7,250 feet MSL.
An increase in temperature with an increase in altitude - ✔✔is indication of an
inversion.
A surface inversion can - ✔✔produce poor visibility.

, The most frequent type of ground or surface based temperature inversion is that
produced by - ✔✔terrestrial radiation on a clear, relatively still night.
Which weather conditions should be expected beneath a low-level temperature
inversion layer when the relative humidity is high? - ✔✔Smooth air and poor visibility
due to fog, haze, or low clouds.
An altimeter indicates 1,850 feet MSL when set to 30.18. What is the approximate
pressure altitude? - ✔✔1,590 feet.
An aircraft is flying at a constant power setting and constant altitude. If the outside air
temperature (OAT) increases, true airspeed will - ✔✔increase and true altitude will
increase.
An aircraft is flying at a constant power setting and constant altitude. If the outside air
temperature (OAT) decreases, true airspeed will - ✔✔decrease and true altitude will
decrease.
As density altitude increases, which will occur if a constant indicated airspeed is
maintained in a no wind condition? - ✔✔True airspeed increases; groundspeed
increases.
Density altitude may be determined by correcting - ✔✔pressure altitude for
nonstandard temperature.
What causes wind? - ✔✔Pressure differences.
The windflow around a low pressure is - ✔✔cyclonic.
Winds at 5,000 feet AGL on a particular flight are southwesterly while most of the
surface winds are southerly. This difference in direction is primarily due to - ✔✔friction
between the wind and the surface.
