The OBS Key was pressed, disabling auto sequencing of waypoints (in a flight plan or
instrument procedure). The OBS Key should be pressed again to enable auto sequencing,
because 1) no destination waypoint has been selected or 2) the GPS receiver cannot currently
determine its position.
The aircraft is inbound and within 3 nm of the FAF; and the active approach is not a GPS-
approved approach. Verify that the VLOC receiver is tuned to the proper frequency and press
the CDI Key to display 'VLOC' (directly above the CDI Key).
The course select for the external CDI (or HSI) should be set to the specified course. The
message only occurs when the current selected course is greater than 10° different from the
desired track.
This message appears approximately one minute prior to a turn in one of the following three
conditions: 1) the turn requires a bank angle in excess of 25° in order to stay on course, 2)
the turn requires a course change greater than 175°, or 3) during a DME arc approach the
turn anticipation distance exceeds 90 seconds.
All user waypoints, flight plans, and system settings have been lost due to a memory battery
failure or system reset.
See Section 11.3 for complete list of TERRAIN related Alerts and Annunciations.
