The following symbols are used on the Nav 4 map page:
3.11.4.8. Selecting The Map Orientation
All KLN 94 installations are capable of three map orientations: actual track
up (TK↑), North up (N↑), and desired track up (DTK↑). In addition, if the
KLN 94 is interfaced with a compatible source of heading then a heading
up presentation (HDG↑) may also be selected.
In the actual track up orientation, viewing the map is like looking at a chart
that is turned so that the direction the aircraft is tracking over the ground is
pointing up. In a no-wind condition actual track is identical to the aircraft’s
heading. The aircraft must be moving at least two knots to calculate the
actual track. The map will be blank at any speed less than two knots.
When the North up orientation is selected, viewing the map is like looking
at a navigation chart with North at the top. The aircraft symbol rotates
based on the aircraft’s actual track (or heading if available). If the KLN 94
does not have a heading input and the aircraft is not moving the aircraft
symbol is replaced by a “+” symbol.
If desired track is selected, the map is like looking at a chart that is turned
so that the course line is always pointing up.
