The air in the earth’s atmosphere is composed mostly of?
nitrogen and oxygen
Standard pressure lapse rate is
1 "Hg per 1,000 feet
High altitude, high temperature, and high moisture content in the atmosphere reduces what?
Aircraft Performance
Amelia Earhart
American aviator, one of the world’s most celebrated, who was the first woman to fly solo across the Atlantic Ocean.
From 1984–1992 I played this charterer on a hit tv show.
Tony Micelli
High density altitude accounts for what percentage of all U.S. aviation weather-related accidents.
7.3%
What is the pressure altitude for the following conditions?
Altimeter: 29.15
Field elevation: 2,597ft
29.92 – 29.15 x 1,000 + 2,597 = ?
3,367 ft
Standard temperature is 15 degrees C but only at sea level. It decreases about 2 degrees C (or 3.5 degrees F) per 1,000 feet of altitude above sea level. The standard temperature at 7,000 feet msl, therefore, is only 1 degree C (or 34 degrees F). The density altitude at an airport 7000 feet above sea level, with a temperature of 18 degrees Celsius and a pressure altitude of 7000 (assuming standard pressure) what is the density altitude?
18 – 1 = 17
17 x 120 = 2040
2040 + 7000 = ?
9040 ft
Orville Wright

Angela Bower
These values are standard pressure, there are three of them.
29.92 inches of mercury (“Hg)
1,013.2 hectopascal (hPa)
14.7 psi
If you're planning on using a performance chart, you need to know two things.
Outside Air Temperature and altitude
The three H's of aircraft performance are?
Hot, High, and Humid
Wilbur Wright
From 1984–1992 I played this charterer on a hit tv show.
Mona Robinson
This region of air pressure is high, so air molecules don’t have as much freedom to move about. Carrying a lot of energy, they collide with each other more frequently, which causes the temperature of the system to increase.
Low Altitude Region
When you set your altimeter to 29.92, you're flying at
standard pressure altitude
High-density altitude corresponds to reduced air density and thus to reduced aircraft performance. There are three important factors that contribute to high-density altitude, what are they?
1.Altitude
2.Temperature
3.Humidity
Sally Ride
was the first American woman in space.
From 1984–1992 I played this charterer on a hit tv show.
Johnathan Bower
What does this diagram explain?
Temperature effects on pressure
If we carry a barometer with us, we can measure a decrease in pressure as the weight of the air above us decreases. This describes what?
Pressure Changes with Altitude
An increase in density altitude results in an decreased what?
rate of climb
Chuck Yeager
U.S. Air Force Captain Chuck Yeager became the first person to fly faster than the speed of sound.
From 1984–1992 I played this charterer on a hit tv show.
