5.3.1. SELECTING THE LEG MODE OR THE OBS MODE
To change navigation modes:
1. From any page (except a message page), turn on the cursor
(
B ).
2. Turn the right inner knob counter
clockwise until the cursor is over
the navigation mode. In this
case, the current mode is Leg
(figure 5-39).
3. Press E . The mode will toggle
between Leg and OBS. In the
case of OBS mode, the selected
course angle will be displayed
(figure 5-40).
4. If you desire to change the
selected course while in OBS
mode, turn the right inner knob
while the cursor is over the mode
annunciation (figure 5-41).
5. Turn off the cursor ( B ).
5.3.2. THE EN ROUTE-LEG MODE
The following are the characteristics of the En route-Leg Mode:
1. The 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 KLX 135. If the CDI or HSI has five dots left and right of the
center position, then each dot represents one nautical mile of
deviation.
2. Navigation is provided along the great circle path between two
waypoints. As you probably know, great circle navigation is the
shortest distance between two points located on the earth's
surface. In the case of Direct To operation, the "from" waypoint
is not displayed but it is the point where Direct To operation was
initiated. The course to fly while in this mode is referred to as the
desired track (Dtk). The desired track is displayed on the NAV 4
page. To fly a great circle course between two points, the
desired track may be constantly changing. A good way to
