What effect does high density altitude have on the efficiency of a UA properller?

Properller efficiency is decreased.

Which combination of atmospheric conditions wil reduce aircraft takeoff and climb performance?

High temperature, high relative humidit, and high density altitude.

Which factor would tend to increase the density altitude at a given airport?

An increase in ambient temperature.

How would high density altitude affect the performance of a small UAS?

Decrease performance.

What effect, if Andy. does high humidity have o aircraft performance?

It decreases performance.

Every physical process of weather is accompanied by, or is the result of, a

Heat Exchange.

What effect does high density altitude, as compared to low density altitude, have on properller efficiency and why?

Efficiency is reduced because the propeller exerts less force at high density altitude than at low density altitudes.
