Entering/Changing of Waypoint Parameters
1. Activate the editing function SELECT.
2. In the PPI, click on the waypoint that is to be processed.
Alternatively (e.g. because the waypoint is not situated in the display range): Click into the field of
the waypoint number and enter the number of the waypoint that is to be processed.
3. Specifying the curve radius: Click on the radius field
and enter the value by means of the virtual keyboard.
This entry must be performed
- at the first waypoint
- at every waypoint at which the curve radius is to
change relative to the preceding waypoint.
☞ The entry of the radius is cancelled by input of the
value 0.
4. If desired, enter the name of the waypoint: Click on the
name field, and enter the name by means of the virtual
keyboard.
5. If the Sailing Mode is to change, make the appropriate
change.
6. For each waypoint, put the entries into effect by clicking
on the APPLY button.
The track is then computed anew. The curves are now
displayed. A curve radius that is entered also affects all of the
following waypoints up to a waypoint for which a different curve
radius has been entered.
If the waypoints have been positioned so unfavourably (short
distance between waypoints, acute angles) and/or the radii
have been chosen so large that the ship will probably not be
able to sail along the track, this situation is indicated by means
of a special display of the track:
- The tracklines (the straight lines up to the last waypoint
and up to the currently valid waypoint) are extended as far
as the waypoints.
- In the display, the circular arc defined by the radius is
moved along the trackline to the last waypoint until it fits
between the two tracklines.
- This movement takes place up to the last waypoint at the
most, but not further than up to a distance of 20 NM
between the beginning of the curve and the waypoint.

Behind the curve end of waypoint 7, this
curve does not fit into the angle formed by
waypoints 7, 8 and 9. Therefore, the
curve is shown displaced, and the display
of the Programmed Track is interrupted
by the display of the tracklines.
