Basic GPS Operation
Chapter 3
If you get off course and wish to recenter the left/right deviation bar
(D-Bar) to proceed to the same waypoint, use the following
procedure.
To recenter the D-Bar by going direct to the active waypoint:
1. Select a non-waypoint page (NAV, FPL, CAL, SET, or OTH) on
the screen.
2. Press
D
. The Direct To page is displayed on the left, contain-
ing the active waypoint identifier.
3. Press
F
.
‡NOTE: If the KLN 89B is in the approach mode and this method is
used to center the D-bar when the missed approach point is the
active waypoint, then the approach mode will be cancelled and the
KLN89B will revert to the approach arm mode.
3.9.2. CANCELLING A DIRECT TO
The primary reason for wanting to cancel Direct To operation is to
return to flight plan operation which is described later in
section 4.2.4
“Combining Direct To and Flight Plan Operation”.
To cancel Direct To operation:
1. Press
D
.
2. Press
E
to blank out the way-
point identifier field (figure 3-109).
3. Press
F
.
3.9.3. WAYPOINT ALERTING FOR DIRECT TO OPERATION
Approximately 36 seconds prior to reaching a Direct To waypoint, the
arrow preceding the waypoint identifier on the waypoint page for the
active waypoint will begin flashing. This arrow will also be flashing on
any NAV or FPL page displaying the active waypoint identifier. This
is called “waypoint alerting”. If an external waypoint alert (WPT)
annunciator is mounted in the aircraft, this annunciator will begin
flashing at the same time.
