Part III, "Radio Magnetic Indicator (RMI)."

The Radio Magnetic Indicator (RMI) is the primary navigational instrument in the aircraft. It

displays aircraft heading in addition to magnetic bearing information from radio stations through the

use of pointers referred to as the VOR and TACAN/GPS (depending on mode selected on GPS

NAV/GPS button) needles (Figure 46).

The IND350 is the secondary navigational instrument in the VOR/TACAN system and serves
