3.3. DISPLAY FORMAT

The KLN 94 uses a color LCD. In normal operation, the display screen is
divided into four segments (figure 3-24). When the map page (NAV 4)
page is displayed the page bar is
removed to maximize the height of
the map. Also, in some cases such
as the display of system messages
the segment dividers disappear and
you have a "full-screen" page.
Display Segment 1 (Navigation Data)
A typical display screen is shown in
figure 3-26. Display segment 1 is
the Navigation Data segment. On all
normal pages segment 1 consists of
four lines of data.
• The top line of segment 1
always displays distance to the active waypoint.
• The identifier of the active waypoint is usually displayed on the sec-
ond line.
NOTE: In cases when the active
waypoint identifier is displayed on a
segment 2 page, line 2 will display
the current groundspeed (figure 3-
27).
• The third line of segment 1 displays the desired track (DTK) when
the KLN 94 is in the LEG mode, its normal mode of operation. DTK
is the course to the active waypoint the aircraft should be flying.
The DTK value will flash if the course selected on the external CDI
or HSI differs from the desired track by more than 10 degrees.
When the KLN 94 is in OBS mode of operation the OBS course is
displayed on line 3. See section 5.5 for modes of operation.
• The aircraft's actual track (TK) over the ground is displayed on line
four. Displaying the DTK and TK together like this makes it easy to
determine the proper heading to fly in order to make the TK match
the DTK. As long as they match the aircraft will remain on course. If
the TK begins to differ from the DTK it won't be long until the devia-
tion needle on the CDI or HSI will start be move off center. See
Appendix A for a graphical description of navigation terminology
such as DTK and TK.
