OBS
When active, this function allows you to set the desired course To/From a waypoint
using the provided controls or with an external OBS selector on HSI or CDI.

Tapping the key again resumes automatic sequencing of waypoints (normal mode).
SUSPEND/UNSUSPEND
The Omni Bearing Selector (OBS) allows you to select
between manual or automatic sequencing of waypoints.
1. Tap OBS.

CDI indicates the OBS heading.
The mode displays on the
annunciator bar.

that do not support OBS.
This key displays for legs that
auto suspend (e.g., leg holds,
missed approaches).
