To activate a waypoint in OBS mode without changing the
selected course:
1. Press
D
(figure 4-125). The
rules described in section 3.8,
"Direct To Operation", dictate
which waypoint identifier will be ini-
tially displayed on the Direct To
page.
2. Press
D
a second time. The
annunciation DIRECT TO changes
to ACTIVATE
(figure 4-126).
Repeated presses of D cause
the annunciation to alternate
between DIRECT TO and ACTI-
VATE. Make sure ACTIVATE is
displayed.
3. If the desired waypoint is not the
one that was suggested by the
KLN 89(B), enter the desired iden-
tifier. Press
F
.
4. Press
F
to approve the waypoint page and activate the waypoint
(figure 4-127). The selected course does not change, therefore this
method does not center the D-Bar like a Direct To operation does.
4.7.8. CHANGING THE CDI SCALE FACTOR
The CDI scale factor can be changed by using the NAV 1 page. In nor-
mal 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 ± 1 NM and the needle was deflected full scale to
the right, the aircraft would be 1 NM left of course. The default CDI
scale factor is ± 5 NM.
To change the CDI scale factor:
1. Select the NAV 1 page.
2. Turn on the cursor ( B ). It will
appear over the second line of the
NAV 1 page, which usually dis-
plays the course deviation indicator
(figure 4-128). This is a cyclic field,
as indicated by the carat (>) pre-
ceding it.
