Instructions
Answer the following questions to test your understanding of aviation altimeters, orientation, and temperature differences with altitude. Show your work where required.
1
An aviation altimeter measures altitude based on atmospheric pressure. What is the primary function of an altimeter?
2
Explain how an altimeter uses changes in atmospheric pressure to determine altitude. Use the relationship between pressure and altitude.
3
Air temperature decreases by approximately 6.5°C per 1,000 meters of altitude gain. If the temperature at sea level is 20°C, what would be the temperature at 2,000 meters?
4
In aviation, orientation is critical. What is the primary factor used to determine an aircraft's orientation relative to the ground?
5
At higher altitudes, air becomes thinner, and temperature decreases. How do these factors affect the performance of an aircraft's altimeter and overall flight performance?
6
Aircraft altitude and temperature changes are closely related. Calculate the temperature change if altitude increases by 1,500 meters, given the rate of 6.5°C per 1,000 meters. Show your calculation.
