What type of altitude is corrected for nonstandard temperature in its calculation?

Density altitude is the type of altitude that is corrected for nonstandard temperature in its calculation. This altitude is particularly significant in aviation as it reflects the pressure altitude adjusted for temperature deviations from standard conditions. The concept of density altitude helps pilots understand how aircraft performance is affected by altitude, temperature, and atmospheric pressure.

Density altitude is calculated by taking the pressure altitude and adjusting it for temperature variations. This means that if the air is warmer than the standard temperature, the density altitude will be higher, which can affect lift, engine performance, and overall aircraft performance. When conditions deviate from the standard atmosphere, knowing the density altitude allows pilots to make informed decisions about their aircraft’s performance capabilities.

The other types of altitude listed do not incorporate temperature adjustments in the same way. For instance, pressure altitude is simply the altitude corresponding to a given atmospheric pressure, and indicated altitude is what the altimeter reads without adjustments for temperature or pressure variations. Absolute altitude refers to the height above the terrain directly below an aircraft, independent of any atmospheric conditions. Thus, density altitude is the only type that specifically integrates temperature correction into its measurement, making it critical for operational safety and aircraft performance.
