The CDI Key is used to toggle which navigation source (GPS or VLOC) provides output to an external HSI or CDI.
The OBS Key is used to select manual or automatic sequencing of waypoints. Pressing the OBS Key selects OBS mode, which retains the current ‘active to’ waypoint as the navigation reference even after passing the waypoint (i.e., prevents sequencing to the next waypoint). Pressing the OBS Key again returns the unit to normal operation, with automatic sequencing of waypoints. When OBS mode is selected, the pilot may set the desired course to/ from a waypoint using the ‘Select OBS Course’ pop-up window, or an external OBS selector on the HSI or CDI.
The MSG Key is used to view system messages and to alert the pilot to important warnings and requirements.
The FPL Key allows the pilot to create, edit, activate, and invert flight plans, as well as access approaches, departures, and arrivals. A closest point to flight plan feature is also available from the FPL Key.
The PROC Key allows the pilot to select and remove approaches, departures, and arrivals from the flight plan. When using a flight plan, available procedures for the departure and/or arrival airport are offered automatically. Otherwise, the pilot may select the desired airport, then the desired procedure.
