Barometric Altimetry

Barometric Altimetry

 

one of the methods of altimetry, based on the relation of air pressure to altitude above sea level, which was established in 1647 by B. Pascal. The pressure is measured with barometers, and corrections that take into account temperature, humidity, and other factors are introduced.

The issue is whether abnormally cold temperatures introduce altitude errors in a barometric altimetry system and if those errors exceed obstacle clearance requirements used on terminal procedure segment altitudes.
anticipated errors in a barometric altimetry system could exceed the Required Obstacle Clearance.
