Forwarding distance
The forwarding distance is the distance the ship travels straight after the steering command is given to the autopilot.
This distance may vary with a different required radius of turn. The logic to verify the correct distance is to perform
a manoeuvre of 90 degrees (Port and Starboard), with a SMALL RADIUS (0.3 NM), and verify from the radar,
using curved EBL, if the turn goes ”long” or is too ”sharp”. The parameter should also be verified with different
radius. (Most important radius values are between 0.3 to 1.0 NM). You can define set of Forwarding Distances both
for "Go To Track" and "Go To WP" steering modes.
In order to get edit Forwarding distances parameters,
proceed as follows:
1. From Control Panel press INITIAL SETTING.
2. From menu select Navigation parameters.
3. From submenu select Forwarding distances.
4. Insert Authorizing key disk to floppy drive.
5. Select Enable changes to modify desired set of
Forwarding Distances.
Normally these parameters are entered during sea trial but can also be modified later on. See figures below:
