Title: Interpret information on a Horizontal Situation Indicator (HSI).
Course: Aircraft Pilot Training I (20053-I) > Section: Examining Aircraft Instruments, Components, Systems, and Performance

Interpretation should include the following:

- The heading indicator is located below the artificial horizon and is normally modeled after an HSI.
- As in the case of the attitude indicator, the heading indicator receives its information from the magnetometer, which feeds information to the attitude and heading reference system (AHRS) unit and then out to the primary flight display (PFD).
