BOTTOM ROW KEYS
The CDI button is used to toggle which navigation source
(GPS or VLOC) drives the external HSI or CDI.
The OBS button is used to select either manual or automatic
sequencing of waypoints. Pressing the OBS button selects
OBS mode which retains the current ‘active to” waypoint as
the navigation reference even after passing the waypoint.
In other words, it prevents sequencing to the next waypoint.
Pressing the OBS button again returns the unit to normal
operation with automatic waypoint sequencing. When OBS
mode is selected, the pilot may set the desired course to or
from a waypoint by using the “Select OBS Course” pop-up
window or an external OBS selector on the HSI or CDI.
The MSG button is used to view system messages and
pilot alerts such as warnings, and requirements.
The FPL button allows the pilot to create, edit, activate,
invert fl ight plans as well as access approaches, departures
and arrivals. The closest point to a fl ight plan feature is
also available by pushing the FPL button.
