WebMar 21, 2024 · Air density is defined as mass divided by volume. It is related to air pressure and altitude and is a measure of how many gas molecules are present. Like air pressure, air density decreases the higher you go. Air at high altitudes with a low density and pressure is often described as rarified, meaning it contains less breathable gases. WebMay 23, 2024 · So, again, no. Density Altitude has nothing to do with your actual height above the ground. It DOES have a lot to do with your speed over the ground. On a cool day at sea level, if your rotation speed is 80, your ground speed will be 80. On a very hot day, at the same airport, your ground speed will be higher to achieve 80 IAS.
