Density Altitude

QuestionAnswer
What is the relationship between temperature and air density? As temperature increases the air density decreases.
What effect, if any, does high humidity have on aircraft performance? It decreases performance.
When operating at a high density altitude, rate of climb decreases.
What is the relationship between humidity and air density? As humidity increases the air density decreases.
If the outside air temperature (OAT) at a given altitude is lower than standard, the density altitude is lower than pressure altitude.
How would high density altitude affect the performance of a small unmanned aircraft? Decreased performance
As air temperature increases, density altitude will increase.
What effect does high density altitude have on the efficiency of a UA propeller? Propeller efficiency is decreased.
If the outside air temperature (OAT) at a given altitude is warmer than standard, the density altitude is higher than pressure altitude.
Air density is affected by air pressure, temperature, and humidity.
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? The payload capacity is reduced.
What is the relationship between air pressure and air density? As air pressure decreases the air density decreases.
Which factor would tend to increase the density altitude at a given airport? An increase in ambient temperature.
Which combination of atmospheric conditions will reduce aircraft takeoff and climb performance? High temperature, high relative humidity, and high density altitude.

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
