Ship parameters:
Ship max. speed:
Maximum speed the ship can perform.
Ship max. height:
Max. height of ship for generating alarms for objects which are hanging above sea level.
Ship draught:
Max. draught of ship for generating alarms for objects which are below sea level.
Gyro error correction:
Used to select method of gyro error correction.
Gyro spd/lat error:
Used to select speeds/latitude correction method of gyro error correction.
Max gyro error correction:
This is the limit for the maximum correction allowed. Typical value 3 degrees.
Manual gyro correction:
Used to adjust gyro correction manually.
Route parameters:
Max Rate of Turn:
Indicates the maximum rate of turn of the ship.
Turn end tolerance:
This defines the window for the detection of the end of turn. Typical values are between 2 to 4 degrees.
WP approach alarm time:
Used to set the alarm time before approaching the wheel over point.
WP prewarn alarm time:
Used to set the alarm time well before approaching the wheel over point.
Route start limit angle:
Used to set the maximum approach angle against planned course in order to accept start of automatic Route Steering.
Default line radius:
Used to define the default value of radius between waypoints during automatic Route Steering.
Drift compensation:
Enables/disables the drift compensation during automatic Route Steering.
Gyro error compensation:
Enables/disables the gyro error compensation of set course during automatic Route Steering.
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).
In order to get edit Forwarding distances parameters, proceed as follow:
1. From Control Panel press INITIAL SETTING
2. From menu select Navigation parameters
