How does density relate to altitude

WebNov 30, 2024 · Density altitude in feet = pressure altitude in feet + (120 x (OAT - ISA temperature)) Pressure altitude is determined by setting the altimeter to 29.92 and reading the altitude indicated on the altimeter. OAT stands for outside air temperature (in degrees Celsius). ISA stands for standard temperature (in degrees Celsius). WebNov 30, 2024 · The altimeter measures static air pressure, which is the pressure of the atmosphere. It is different from a barometer, which only indicates atmospheric pressure, whereas an altimeter translates atmospheric pressure into altitude. This is important for pilots to know so they have an accurate concept of how high the aircraft is.
