DESCRIPTION/FUNCTION
1
Enter TACAN identifier or waypoint.
2
Select MAN advance (if desired) to
prevent waypoint passage into history.
Enter the desired/published course in the
3
scratchpad.
4
Enter the course to/from the waypoint.
5
A FROM indicator is provided when the
station is passed. The waypoint does not
move into history.
6
Indicates type of course entry: Computed
(blank), Manual (man), or Direct-To
computed (dir).
(c) Modifying
When scrolling back into the history waypoints, the
waypoint immediately preceding the active waypoint is
the current FROM waypoint.
provides steering to intercept the course between the
FROM and TO waypoints. By entering a new FROM
waypoint, the FMS steers to intercept a new course
between the newly entered FROM and original TO
waypoints. Figure 3C-41 is an example of the effect of
modifying the FROM waypoint on guidance to the
active waypoint.
(6) Waypoint Steering Data. Once an active
flight plan is entered, the FMS-800 computes the
pilot's steering solution. The nomenclatures on the
CDU refer to the steering data that is entered into the
pilot's flight instruments.
