Direct To Operation - Honeywell KLN 900s Pilot's Manual

3.8 DIRECT TO OPERATION

The D button is used to initiate Direct-To operation
(navigation from your present position direct to your desti-
nation). When D is pressed, the Direct-To page is dis-
played on the left side with a flashing cursor over a way-
point identifier (figure 3-87). The waypoint identifier
which appears on the Direct To page is chosen by the
KLN 900 according to the following rules:
1. If the Flight Plan 0 page is displayed on the left side
and the cursor is over one of the waypoint identifiers
in Flight Plan 0 when D is pressed, then that way-
point identifier will appear on the Direct To page. (You
will appreciate this feature when you learn to use flight
plans in chapter 4).
2. If the KLN 900 is displaying the Super NAV 5 page
and the right inner knob is in the "out" position when
D is pressed, then the waypoint highlighted in the
lower right hand corner of the Super NAV 5 display
will be the default waypoint. (You will also find this fea-
ture useful when operating from the active flight plan
especially during approaches).
If neither of the two previous conditions are occurring,
then:
3. If there is any waypoint page (APT 1-8 page, VOR
page, NDB page, INT page, SUP page, or ACT page)
in view on the right side when D is pressed, then
the Direct To page will contain the identifier for the
waypoint page being viewed on the right side.
If none of the previous three conditions are occurring,
then:
4. When D is pressed, the waypoint identifier for the
current active waypoint will be displayed. However, if
the active waypoint is the Missed Approach Point and
the aircraft is on the "from" side, then the KLN 900 will
display the first waypoint of the missed approach
procedure on the Direct To page.
5. If there is no Direct To waypoint and there are no way-
points in Flight Plan 0 when D is pressed, then the
Direct To page will display blanks.
All right, rules are rules, you say. But how do I perform
Direct To navigation? Since you won't learn flight plan
operation until later, let's see how to apply rules 3 and 4
at this time to proceed Direct To our desired destination,
Oshkosh, Wisconsin. The identifier for Wittman field in
Oshkosh is KOSH.
