5-7 Navigation

OBS MODE

“PUSH OBS” is the label underneath the knob and is active when

you can put the system in To/From course setting mode for a

waypoint. There is no need for “suspend” functionality in the IFD

paradigm – the IFD will continue sequencing to the next waypoint

and exit OBS mode at that time.

NOTE

GPS and OBS

If GPS or OBS are not the active Nav state

(annunciated in green), then pushing the Nav

Source knob will have no effect. When one of them

is the active Nav state, pushing the Nav Source

knob will toggle between the two states.

NOTE

OBS Can Not Be Activated Inside the FAF

OBS is prevented from being selected on a

published approach when inside the Final Approach

Fix (FAF).

NOTE

OBS Behavior in Dual IFD Operations

For those installations that include dual IFDs t hat

are separately wired to two different nav indicators,

the #2 IFD will automatically switch into OBS mode

when #1 IFD Nav Source has been put into OBS

and the #2 nav indicator will flag invalid. This is

because the FMS stays sync’d between the two

IFDs. The #2 IFD will display the selected course

as set by the #1 nav indicator on the map page.
