FTT 111 9352 UPDATED ACTUAL CERTIFICATION
EVALUATION EXAMS 2026 QUESTIONS WITH
PRACTICE SOLUTION GRADED A+
◉ Inversion (Atmospheric Stability). Answer: -Usually temperature
decreases with altitude
-Inversion occurs when temperature of air rises with altitude
-Temperature of air increases with altitude to a certain point; (Top of
Inversion acts as a Lid)
-If Relative Humidity is high it can create clouds, fog, haze, or smoke
resulting in diminished visibility
◉ Unstable Air. Answer: Often results in:
-Cumuliform clouds
-Rough air (turbulence)
-Showery precipitation
-Good visibility
,◉ Atmosphere Pressure (Barometric Pressure). Answer: -Stations
use 1" Hg (hectographs) for every 1000 ft of elevation above sea
level
-Measured in "Hg or Mb (millibars)
-Sea Level Pressure = 29.92" Hg/ standard 59'F or 1,013 mb
-1"Hg = 34 mb
-Typical Mb pressure is 950.0 - 1,040 mb
-All weather stations use Sea Level Pressure to provide reports
◉ Stable Air. Answer: -Strati form Clouds and Fog
-Continuous precipitation
-Smooth air
-Fir to Poor Visibility in haze and smoke
, ◉ Effects of Pressure on Density. Answer: -Pressure Up = Density Up
-Pressure Down = Density Down
-IF TEMPERATURE REMAINS THE SAME
◉ Relative Humidity. Answer: -Amount of Water Vapor contained in
the Atmosphere
-Expressed as a % of maximum amount of water vapor air can hold
-Varies with Temperature = Warm air holds more water vs. Cold air
holds less water
-Dry Air = 0% Humidity
-Wet Air = 100% Humidity (cannot hold any more water)
◉ Factors Affected by Performance. Answer: -Take off distance
-Landing distance
-Rate of climb
-Ceiling
