3.9 THE NAVIGATION PAGES
As you would expect, the NAV (navigation) pages contain
information relating specifically to the KLN 900’s naviga-
tion capabilities. The KLN 900 has five NAV pages.
Unlike any other pages, these pages may be selected
and viewed on both the left and right sides of the screen.
The procedure for selecting specific pages, including the
NAV pages, was described in section 3.4.1, “Page
Selection.” This section will cover all NAV pages except
for the NAV 4 page (Vertical Navigation) which is
explained in section 5.2.
3.9.1 The Navigation 1 Page (NAV 1)
A NAV 1 page is shown in figure 3-97. A NAV 1 page
displays the following information:
• The active navigation leg. For Direct To operation this
consists of the Direct To symbol,
H
, followed by the
active Direct To waypoint identifier (figure 3-97). For
the leg of a flight plan this consists of the “from” way-
point identifier and the active “to” waypoint identifier
(figure 3-98). An arrow (
>
) precedes the active way-
point identifier.
• A course deviation indicator (CDI) that displays left
and right deviation from the desired track. The devia-
tion bar operates like a navigation deviation needle on
a conventional CDI or HSI. An on-course indication is
displayed when the deviation bar is centered on the
triangle in the middle of the CDI. In both modes each
dot represents one nautical mile deviation from the
desired track. Therefore, the CDI shows course devi-
ation five nautical miles left and right of course. For
example, a deviation bar positioned two dots to the
right of the center triangle indicates that the aircraft is
two nautical miles to the left of course (figure 3-99).
The center triangle also serves as the CDI’s
TO/FROM indicator and operates in the same manner
as a conventional CDI TO/FROM indicator; an “up” tri-
angle indicates “to” the active waypoint while a “down”
triangle (figure 3-100) indicates “from” the active way-
point. The word “FLAG” is displayed over the CDI
when the KLN 900 is not usable for navigation (figure
3-101).
NOTE: It is possible to change the CDI scale factor to be
0.2 nm per dot or 0.06 nm per dot. See section 5.9.8.
• Distance (DIS) to the active waypoint.
• Groundspeed (GS)
• Estimated time enroute (ETE) to the active waypoint.
• Bearing (BRG) to the active waypoint.
