heat exchange. movement of air. pressure differential.

59°C and 1013.2 millibars. 59°F and 29.92 millibars. 15°C and 29.92″ Hg.

High temperature, high relative humidity, and high density altitude. Low temperature, low relative humidity, and low density altitude. High temperature, low relative humidity, and low density altitude.

It increases performance. It has no effect on performance. It decreases performance.

Efficiency is reduced because the propeller exerts less force at high density altitudes than at low density altitudes. Efficiency is reduced due to the increased force of the propeller in the thinner air. Efficiency is increased due to less friction ...

Propeller efficiency is decreased. Density altitude does not affect propeller efficiency. Propeller efficiency is increased.

Decreased performance. Increased performance. No change in performance.

The type of the sUAS operation. Current weather conditions. The number of available ground crew.

A decrease in relative humidity. An increase in barometric pressure. An increase in ambient temperature.
