entation field (figure 3-111). Rotate the appropriate inner
knob to display N

for North up, DTK

for desired track

up (figure 3-112), TK

for actual track up (figure 3-113),

or HDG

for heading up (figure 3-114). The heading up

selection is not presented as a choice if heading is not
provided to the KLN 900. If the cursor is moved to the
map range scale using the outer knob or if the cursor is
turned off with the

button, then the DTK

, TK

, or

HDG

annunciation is replaced with the actual value.

The 123 ° displayed in the lower left corner of figure 3-
115 shows how the actual track angle is displayed when
the cursor is not over the map orientation field as it was in
figure 3-113.

If a heading input is available to the KLN 900 then head-
ing up is usually the best map orientation to select.
Otherwise, actual track up display is usually preferred for
use in flight. However, the track up display is only usable
when the aircraft is moving 2 knots or more so the North
up display may be a good choice while operating with
very slow ground speeds.

Notice that in both the North up format and the desired
track up format, the aircraft’s position is depicted by a dia-
mond. In the actual track up format and the heading up
format, the aircraft’s position is depicted by an aircraft
symbol.

The range scale is displayed in the lower right corner of
the NAV 5 page. The range scale indicates the distance
from the aircraft’s position (the diamond or aircraft sym-
bol) to the top of the screen. Range scale selections from
1 NM to 1000 NM or from 2 km to 1850 km may be made
by pressing the appropriate

and turning the appropri-

ate inner knob. For example, figure 3-116 illustrates the
results of changing the range scale of the map in figure 3-
110 from 40 nautical miles to 15 nautical miles.

When the NAV 5 page is displayed on the left side of the
screen and any selected waypoint page is displayed on
the right side, the location of the selected waypoint is indi-
cated by a “+” on the NAV 5 page (figure 3-117). Of
course, the display scale must be chosen which allows
the selected waypoint to be displayed.
