What displays when the IRS alignment process is complete?

When the IRS alignment process is complete, the aircraft's heading will be accurately displayed on the Horizontal Situation Indicator (HSI) lubber line, and the actual latitude and longitude will be shown on the SET POS line of the Flight Management System (FMS) Control Display Unit (CDU). This functionality is crucial for navigation and helps ensure that the aircraft is accurately oriented and positioned, which enhances situational awareness for the pilots.

The completion of the IRS alignment indicates that the inertial reference system has calibrated the aircraft's position and heading correctly. This information is essential for various flight operations, including navigation and autopilot functionality, as it ensures the aircraft is operating with accurate data.

Other options may indicate alerts or incomplete states of IRS alignment, but they do not represent the fully functional state that is characterized by the correct display of heading and position data.
