Density Altitude - A number of factors (altitude/pressure, temperature and humidity) influence air density. A higher altitude, low pressure area, higher temperature and high humidity all have one result: they lower the density of the air. And as a result of that: a reduction in aircraft and engine performance.

Air density is affected by the air pressure, temperature and humidity. The density of the air is reduced by decreased air pressure, increased temperatures and increased moisture. A reduction in air density reduces engine horsepower, reduces aerodynamic lift and reduces drag.

Relative humidity and altimeter setting data in the USA is available from the National Weather Service (NWS) and the Federal Aviation Administration (FAA).
