This software entitled as AirDensity 1.0, is a Palm-OS application and helps you calculate both Air Density and Density Altitude. It works as a flying air dens
ity calculator that can calculate air density and density altitude based on input of three variables: temperature in Fahrenheit, relative humidity as a % satura tion, and barometric pressure.
If you are a pilot, you can then use the density altitude calculation to determine the length of runway that you need for lift-of
f given the weight of your plane, fuel, passengers and cargo.
