How the Barometric Altimeter Works and Common Errors

Understand the aneroid capsule mechanism, non-standard temperature errors, and static port blockages.

The pressure altimeter is an absolute pressure gauge calibrated to translate static ambient air pressure into height above a selected datum.

Aneroid Capsule Operation

Sealed aneroid wafers expand as static pressure decreases with altitude and compress in denser air at lower levels, driving gears connected to the needle display.
