Collision Avoidance Criteria
Collision avoidance must be carried out in strict compliance with the
COLREG.
Relative velocity is fundamental to the activity of collision avoidance. The
system calculates relative velocity in both ground and sea stabilisation
modes and presents individual target CPA/TCPA data. This same data is
used when evaluating whether a target is infringing the operator selected
CPA/TCPA, bow crossing and target association limits. The VisionMaster
system is designed in such a way as to minimise errors in the collision
avoidance calculations which result from the sensors selected for
stabilisation. In practice, however, different sensors may contribute to the
possibility of errors in calculation and caution should be used when
interpreting the data, particularly when ground stabilisation is selected.
