Types of Altitude To fundamentally understand density altitude, you need to understand the five types of altitude used in aviation: Indicated altitude: the altitude read on the altimeter (regardless of altimeter setting) Pressure Altitude: the indicated altitude of the altimeter when it is set to 29.92

Indicated altitude shows the altimeter reading, while true altitude refers to height above MSL. Absolute altitude measures height above ground, which is critical during approaches and landings. Pressure and density altitudes impact performance, while flight levels separate at high altitudes.
