Both the EADI and EHSI operate in what modes?

The EADI (Electronic Attitude Display Indicator) and EHSI (Electronic Horizontal Situation Indicator) are critical components in an aircraft's avionics suite, particularly in the T-6 aircraft. Both instruments provide essential flight data and situational awareness to pilots.

Operating in enroute and approach modes is significant because these modes encompass the majority of a flight's critical phases. The enroute mode is utilized when the aircraft is traveling at cruising altitude, away from takeoff and landing, providing information on the aircraft’s lateral and vertical position, course, and navigational data. On the other hand, the approach mode is specifically designed for when the aircraft is preparing to land, offering vital information such as glide slope status, lateral guidance, and distance to the runway.

This functionality is crucial for pilots to maintain proper orientation, situational awareness, and adherence to flight paths during these phases of flight. By focusing on enroute and approach, pilots can better understand and respond to the changing dynamics of flight as they navigate toward their destination.
