The multiplier for calculation of rudder angle to freeze when gyro failure alarm has occurred in
turning control is adjustable by the hexadecimal number.
The available setting range is from [0000] to [FFFF].
Default setting : [0064]
The properly(theoretical) rudder angle to freeze when gyro failure alarm has occurred in turning
control is calculated by following formula.
3 x V
Theoretical rudder angle in radius control=-----------------------------x k1
60 x
π x R x K
V=Ship’s speed(kt)
π=the circular constant
R=radius(nm)
K=ship’s rate constant
