High density altitude accounts for what percentage of all U.S. aviation weather-related accidents.
7.3%
200
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

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
400
When you set your altimeter to 29.92, you're flying at
standard pressure altitude
400
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

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
