3.Press Eto approve the waypoint page displayed on
the right side. The right side will now display the NAV
1 page, and the left side will return to the page which
was displayed prior to pressing D(figure 3-96). If
the Direct To was started while the NAV 1 page was
shown on the left side then the left and right pages will
revert to the pages that were shown before the Direct
To was started. The selected waypoint is now the
active Direct To waypoint.
3.8.3 To Recenter The D-Bar
If you get off course and wish to recenter the left/right
deviation bar (D-Bar) to proceed to the same waypoint:
1.Select a non-waypoint page (NAV, D/T, REF,or CTR)
or the active waypoint page on the right side.
2.Press D. The Direct To page is displayed on the
left, containing the active waypoint identifier.
3.Press E.
NOTE: If the KLN 90B 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 unit will revert to the
approach arm mode.
3.8.4 To Proceed Direct To Another Waypoint
You may proceed Direct To another waypoint other than
the active one by using Direct To procedure 1 or 2 at any
time.
3.8.5 Cancelling Direct To Operation
The primary reason for wanting to cancel Direct To opera-
tion is to return to flight plan operation which is described
later in section 4.2 “OPERATING FROM THE ACTIVE
FLIGHT PLAN.” To cancel Direct To operation:
1.Press D
2.Press @
3.Press E
3.8.6 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
Navigation page or Distance/Time (D/T) page displaying
the active waypoint identifier. On the Super NAV 5 page,
the entire waypoint identifier will start to flash. This is
called “waypoint alerting”. If an external waypoint alert
annunciator is mounted in the aircraft, this annunciator
will begin flashing at the same time.
