F-Distance - Simrad Maris ECDIS900 Operator's Manual

F-Distance

M , NM
INIMUM RADIUS
It is the limit for maximum turning radius that used to check planned route against the ship
dynamics
F-D
ISTANCE
Press the F-Distance button to set or adjust distances to start turn for the ship. The Distance
to start turn table of distances dependent from the ship speed, which is used to calculate
WOL position. Parameter is very important to setup properly to reach precise steering.
A S
LARM ETTINGS
C
OURSE DIFFERENCE LIMIT FOR STARTING
It is the limit of difference between ship heading and active leg course which makes
impossible to activate TCS. Use the Back on track function to build temporary route, which
makes possible to join the planned route using TCS function.
L ,
OW SPEED LIMIT KN
The parameter is used to trigger alarm in case TCS is active and vessel speed is less then
specified threshold. Meaning that autopilot is not able to provide proper steering quality
under specified conditions.
H
EADING MONITORING THRESHOLD
The parameter is used to monitor two GYRO values. difference. Alarm is triggered in case
difference exceed the specified threshold.
P
OSITION MONITORING THRESHOLD
The parameter is used to monitor two GPS positions difference. Alarm is triggered in case
difference exceed the specified threshold.

CALCULATION WHILE TURNING
Select XTD from ROT curve when using (new) autopilot type which need XTD

calculation during turning not from turning curve.
Select XTD from straight line, using (old) autopilot type which need calculation from
