Changing The Cdi Scale Factor - Honeywell BENDIX/KING KLN 94 Pilot's Manual

3. If the desired waypoint is not the one that was suggested by the
KLN 94, enter the desired identifier. Press F.
4. Press F to approve the way-
point page and activate the
waypoint (figure 5-49). The
selected course does not
change, therefore this method
does not center the D-Bar like a
Direct To operation does.

CHANGING THE CDI SCALE FACTOR

The CDI scale factor can be changed by using the NAV 1 page. In normal
operations it is possible to select a CDI scale factor which is plus or minus
5 NM, 1 NM or 0.3 NM full scale deflection. This means that if the scale
factor was ± 5 NM and the needle was deflected four dots to the right, the
aircraft would be 4 NM left of course. The default CDI scale factor is ± 5
NM. The default scale factor is automatically selected each time the
KLN 94 is turned on. Changing the scale factor on the NAV 1 page also
changes the scale factor on the remote CDI or HSI.
To change the CDI scale factor:
1. Select the NAV 1 page.
2. Turn on the cursor (B). It will appear over the CDI scale number
below the right side of the CDI.
3. Rotate the right inner knob to
select the desired CDI scale fac-
tor (figure 5-50). The valid
choices are 5.0 NM, 1.0 NM, and
0.3 NM or 9.3 km, 1.9 km, and
.56 km.
4. Turn off the B. The CDI scale factor change is complete.
NOTE: The KLN 94 will automatically select a scale factor as part of the
GPS approach process. When the KLN 94 selects a CDI scale factor it is
not possible to select a scale factor that is less sensitive than what the
KLN 94 has automatically chosen. For example, as you will see in the
next chapter, the approach-arm (or terminal) 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.
