due Westerly, and finally Southwesterly by the time
you reach Manila. Of course, your trips with the KLN
90B will be substantially shorter and the desired track
will probably change only a few degrees.
3. Automatic waypoint sequencing is provided during
flight plan operation. As you reach a waypoint in your
flight plan, the next leg of the flight plan automatically
becomes active. There are some situations during
approach operations in which automatic sequencing is
automatically disabled, see chapter 6.
4. Turn anticipation may be utilized in flight plan opera-
tion as described in section 4.2.2.
5. The Minimum Enroute Safe Altitude (ESA) displayed
on the NAV 3 page is the highest MSA sector altitude
from the present position to the destination waypoint
along the active flight plan or Direct To route
(whichever is in use). See section 3.9.4.
5.9.3 The OBS Mode
The following are characteristics of the OBS mode. Item
1 is the same as for 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 90B. If
the CDI or HSI has five dots left and right of the center
position, then each dot represents one nautical mile of
deviation.
NOTE: In some installations where the KLN 90B is inter-
faced to certain models of EFIS equipment, the scale fac-
tor will be plus or minus 7.5 nautical miles, full scale.
Refer to the Flight Manual Supplement for the aircraft or
the Pilot’s Guide for the EFIS equipment for details.
2. The course is defined by the active waypoint and the
selected magnetic course. A course “to” or “from” the
active waypoint may be selected.
3. The course selection is normally made by changing
the selected course displayed on an external indica-
tor such as an HSI, CDI or EFIS. When this is done,
the pilot must verify that the proper course has been
selected by confirming the digital selected course
readout displayed on the KLN 90B. In the OBS mode
the selected course is always displayed as part of
the mode annunciation at the bottom center of the
screen on all pages but the Super NAV 5 page. On
the Super NAV 5 page, the mode/annunciation is
displayed on the left side of the screen. In many
installations, two or more navigation sources can
displayed on one indicator. In these situations there
is a switch in the panel which will determine what
navigation source is displayed. For the KLN 90B to
properly read the external indicator the KLN 90B
