10.15.4 The performance of Sense and Avoid systems may be categorised using the following criteria and the ability to:
1. Accept externally defined fixed exclusion zones (e.g. based on geographical data);
2. Accept externally directed control (third party) (e.g. VTS);
3. Accept dynamic data on both fixed and moving obstacles via automatic electronic sensors (such as AIS, Radar
with automatic target tracking (ATT);
4. Take control of the MASS heading;
5. Take control of the MASS propulsion;
6. Interpret Situational Awareness sensor data automatically to provide the following information regarding any
other object within range:
a. its position;
b. whether it is a vessel according to COLREGs;
c. if so, the aspect of the vessel in terms of its heading;
d. its course and speed, either absolute or relative to the MASS;
e. its classification according to COLREG (not under command, restricted in her ability to manoeuvre, sailing,
fishing, constrained by her draft);
7. Calculate and apply manoeuvring commands where practicable in such a manner as to comply with an
appropriate interpretation of COLREGs where applicable;
8. Calculate and apply manoeuvring commands in such a manner as to avoid collisions under all circumstances
in which it is practicably feasible to do so.
10.15.5 A classification matrix may be used to summarise the performance level of a Collision Avoidance System. The
CA Category required for the MASS should be determined by the vessel category, Level of Control and operating
area. An illustrative matrix is given at Table 10-2.
