Also called Pressure Altitude. Barometric Altitude is the altitude
which corresponds to a given value of atmospheric pressure according to
the ICAO standard atmosphere. It is the indicated altitude of a pressure
altimeter at an altimeter setting of 29.92 inches of mercury (1013.2
mb); therefore it is the indicated altitude above the 1013.2 mb
constant-pressure surface. RT
