Title: Interpret altimeter readings and settings.
Course: Aircraft Pilot Training I (20053-I) > Section: Interpreting Flight Instruments

Interpretation should include the following concepts:

- There are two means by which the altimeter pointers can be moved. The first is a change in air pressure; the other is an adjustment to the barometric scale.
- When the aircraft climbs or descends, changing pressure within the altimeter case expands or contracts the aneroid barometer. This movement is transmitted through mechanical linkage to rotate the pointers.
