5.2. ADVISORY VNAV OPERATION
The KLN 94’s advisory vertical navigation (VNAV) feature allows you to
program a descent or ascent path, and then provides you with an advisory
altitude to fly that will provide guidance along the vertical path. For exam-
ple, you can program the VNAV to provide descent guidance so that you
arrive at your active waypoint or a waypoint in the active flight plan at an
altitude that you specify. The KLN 94 will alert you of when to start the
descent, and display the advisory altitudes to fly throughout the descent.
Vertical navigation is always set up on the ALT 2 page but may then be
viewed on the NAV 1, NAV 4 (map), or ALT 2 pages.
5.2.1. VNAV FOR DIRECT TO OPERATION
The Altitude 2 (ALT 2) page is used to program the KLN 94 for vertical
navigation. To get to the ALT 2 page from any non-altitude page, press
the
A
button twice. The following example will be used to illustrate how
to use the VNAV feature. You are using the KLN 94 to fly direct to your
destination airport, Dubuque Municipal airport (KDBQ) located in
Dubuque, Iowa. You are presently about 65 nautical miles west of
Dubuque, flying at 7500 feet MSL
(figure 5-5). You desire to use the
VNAV to provide vertical guidance to
Dubuque’s traffic pattern altitude of
1900 feet MSL.
To use VNAV on a Direct To:
1. Select the ALT 2 page by press-
ing the
A
button twice (figure
5-6). The aircraft’s actual alti-
tude (7500 feet) is displayed on
the left side of line 2. If the dis-
played altitude is incorrect it is
probably because you have not recently updated the KLN 94’s altime-
ter baro setting on the ALT 1 page.
