Chilling Result Of Cold Temperatures On Baro Altimeters

Barometric altimeters on modern aircraft with digital Air Data Computers are very accurate most of the time and we rely on these altimeters in every aspect of today’s air travel. We diligently set the local altimeter settings prior to each takeoff and each approach but we do not routinely make any corrections for non-standard temperatures. This FSF document explains the chilling result of cold temperatures on barometric altimeters.
