- Position of the waypoint. Geographical position based on WGS 84.
- Curve radius. Radius of the curve along which the ship is to sail at the waypoint
- Sailing Mode. This specifies whether a track section longer than 20 NM from this waypoint to the
next one is to be displayed as a rhumb line (Sailing Mode = RHUMB LINE) or as a great circle
(Sailing Mode = GREAT CIRCLE)

- Track Control Mode. (TO WAYPOINT or TO TRACK). In the system configuration involved here,
this parameter is not important.
General Editor Characteristics
The position of the waypoints can be defined graphically or by alphanumeric input (both when a new
waypoint is being inserted and when the waypoint position is being changed).
When a new waypoint is being inserted, the curve radius, Sailing Mode and waypoint name are taken
over from the preceding waypoint and are also entered for the inserted waypoint.
Selecting the editing function is done by clicking on the
editing function button by means of the MORE key and
then clicking on the desired function by means of the DO
key.
The editing function is activated by clicking on the
editing function button. This is also in the active state
immediately after an editing function has been selected.
The fact that the editing function is active is indicated by
the fact that the editing function button is flashing.
The active editing function is deactivated by clicking on
the (flashing) editing function button or by clicking into the
PPI by means of the MORE key.
Every entry of waypoint parameters in the EDIT
TRACK menu must be completed by pressing the APPLY
button.
For graphic editing, at least the display of the legs and of the waypoint symbols must be in the
switched-on state - see page 38.
Entering of Waypoint Data
The sequence in which editing is performed is partly a matter of personal preference and partly
dependent on the circumstances. For example, all waypoints can first be inserted graphically; then, in the
second step, the position is set alphanumerically to the precise value if necessary. (This procedure is
described in the following.)
WARNING:
Naturally, the inserting and moving of the waypoints can also be
performed generally by means of alphanumerical inputs. If a track lying
outside the radar range is to be edited while the ship is sailing, the
graphical methods are usually not appropriate.
1)
Great circle approximation: If the Sailing Mode GREAT CIRCLE has been entered at a waypoint on the Pre-planned Track and the
distance from the next waypoint is larger than 20 NM, this track section is automatically approximated to a great circle. For this purpose,
the program divides this track section into subsections, each having a length of 10 NM, and places the ends of these subsections on the
great circle.
