3. Press the
E
button until this
line changes to the CDI scale
field (figure 4-129).
4. Rotate the right inner knob to
select the desired CDI scale factor
(figure 4-130). The valid choices
are 5.0 NM, 1.0 NM, and 0.3 NM
or 9.3 km, 1.9 km, and .56 km.
5. If desired, you may press E to
switch the display back to the
graphical CDI.
6. Turn off the
B
. The CDI scale
factor change is complete.
‡NOTE: The KLN 89B will automatically select a scale factor while in
one of the approach modes. When the KLN 89B selects a CDI scale
factor it is not possible to select a scale factor that is less sensitive
than what the KLN 89B has automatically chosen. For example, as
you will see in the next chapter, the approach-arm mode usually has
a scale factor of ± 1 NM. While in the approach-arm mode it is not
possible for you to select the ± 5 NM scale factor. This is to ensure
proper operation of the approach modes.
4.8. THE FUEL MANAGEMENT PAGES
Certain models of fuel management computers manufactured by
Shadin Company, ARNAV Systems, Inc., and Sheltech Ltd. May be
interfaced with the KLN 89(B). The primary benefit of having the KLN
89(B) interfaced with a “real time” fuel management computer is that
the system can continuously compute the amount of fuel required to
reach the destination and the amount of fuel that will be on board
upon reaching the destination. The concept is the following. The fuel
management computer continuously sends the rate of fuel flow and
the amount of fuel remaining to the KLN 89(B). The KLN 89(B) con-
tinuously calculates the aircraft’s distance, groundspeed, and
estimated time enroute (ETE) to the destination waypoint. The fuel
required to reach the destination waypoint is the ETE multiplied by
the current rate of fuel flow. The amount of fuel that will be remaining
at the destination is the amount of fuel presently remaining minus the
fuel required to reach the destination.
