How to Calculate Density Altitude (Without a Math Degree)

Pilot Institute

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 Press ENTER. Press ENTER.

How to Read METAR and TAF Reports

Pilot Institute

Altimeter Pressure (A2990) The next part of the report indicates the local atmospheric pressure, measured in inches of mercury (inHg). Pilots use this value to adjust their altimeters, ensuring they display altitude as close to mean sea level (MSL) as possible. Its also possible to report negative temperatures with an M prefix.

Trial by Ice

Air Facts

Flying a single engine airplane, under IFR, in the clouds, in a non-radar environment and without an autopilot, adds a great deal to the pilots work load. With three airplanes, we departed Springfield for Fairfield, Iowa to compete in an NIFA competition against five other schools. This was the situation on Friday, December 1, 1972.

RNAV Approaches Simplified: A Guide for New Pilots

Pilot Institute

These would guide them when they couldn’t see anything outside their airplane. Theyre pretty much the same thing, but heres the difference: DH is measured above the ground (AGL). LPV is the most accurate RNAV approach and can get you as low as 200 feet above the ground (AGL), just like an ILS Category I approach.

The 6 Types of Altitude in Aviation (Airplane Pilots)

Pilot Institute

Indicated altitude shows the altimeter reading, while true altitude refers to height above MSL. Indicated Altitude Indicated altitude is the reading on the altimeter when the altimeter setting is set to the local barometric pressure. Radio or radar altimeters measure absolute altitude, usually up to 2,500 feet AGL.
