PRIMARY FLIGHT DISPLAY
Navigation Source
NOTE: OBS is only available with the active flight
plan leg, when navigating under GPS.
The HSI can display two sources of navigation, GPS
or NAV (VOR, localizer, and glideslope). In GPS mode,
the flight plan legs are sequenced automatically. Enabling
OBS mode suspends auto sequencing of waypoints, but
retains the current "active-to" waypoint as the navigation
reference, even after the waypoint is passed. When OBS
is disabled, the GPS returns to normal operation, with
automatic sequencing of waypoints. OBS mode also
allows the pilot to set the desired course TO/FROM a
waypoint.
Color indicates the current navigation source: magenta
(GPS ) or green (VOR and LOC). As the user crosses the
MAP, "SUSP" appears on the HSI in place of OBS and the
OBS softkey now reads "SUSP", indicating that automatic
sequencing of approach waypoints is suspended at the
MAP. The following yellow annunciations may appear on
the HSI:
• INTEG – RAIM not available
• WARN – GPS detects position error
To change between navigation sources:
1. Press the CDI softkey to change from GPS to
VOR1 or LOC1. This places the cyan tuning box
over the NAV1 standby frequency in the upper
left corner of the PFD.
Press the CDI softkey again to change from
2.
VOR1 or LOC1 to VOR2 or LOC2. This places
the cyan tuning box over the NAV2 standby
frequency.
Press the CDI softkey a third time to return to
3.
GPS.
