Question 1: What is the relationship between temperature and air density?
Answer:
As temperature increases the air density decreases.
Question 2: What is the relationship between humidity and air density?
Answer:
As humidity increases the air density decreases.Question 3: Which combination of atmospheric conditions will reduce aircraft takeoff and climb performance?
Answer:
High temperature, high relative humidity, and high density altitude.
Question 4: When operating at a high density altitude, rate of climb
Answer:
decreases.
Question 5: What effect does high density altitude have on the efficiency of a UA propeller?
Answer:
Propeller efficiency is decreased.Question 6: If the outside air temperature (OAT) at a given altitude is lower than standard, the density altitude is
Answer:
lower than pressure altitude.Question 7: If the outside air temperature (OAT) at a given altitude is warmer than standard, the density altitude is
Answer:
higher than pressure altitude.Question 8: Which factor would tend to increase the density altitude at a given airport?
Answer:
An increase in ambient temperature.Question 9: A proposed flight requires operating out of an area where the elevation is 5,500 feet and the temperature is 80 degrees F. What is the effect of these conditions on payload capacity?
