4.7. NAVIGATION MODES
The KLN 89(B) allows you to choose how the course to the active
waypoint is defined. This is done by selecting between the two
course modes, LEG and OBS. The LEG mode means that the course
to the active waypoint is selected by the KLN 89(B), and is the default
mode when the KLN 89(B) starts up. The other course mode, OBS, is
the mode that allows you to select the course to or from the active
waypoint. In this mode, the KLN 89(B) operates very much like a
VOR receiver. This is the mode that you will use quite often if you
conduct any non-precision approaches using the KLN 89B.
‡The KLN 89B also has three modes
that are associated with approach
operations. These are Enroute,
Approach Arm and Approach Active.
These modes will be explained in
Chapter 5.
The course mode is annunciated on
the left side of the screen, line 3.
When in the Leg mode, it displays
Leg (figure 4-119), and when in the
OBS mode, it displays the selected
magnetic course (figure 4-120).
4.7.1. SELECTING THE LEG MODE OR THE OBS MODE
To change course modes:
1. Press the
H
button.
2. If the KLN 89(B) was previously in the Leg mode, it will now be in
the OBS mode, and vice versa.
4.7.2. THE LEG MODE
The following are the characteristics of the Leg Mode:
1. The default course deviation indicator (CDI) sensitivity is plus and
minus five nautical miles, full scale. This applies to the CDI on
the NAV 1 page as well as any external CDIs or HSIs interfaced
to the KLN 89(B). If the CDI or HSI has five dots left and right of
the center position, then each dot represents one nautical mile of
deviation.
