Elements and Performance Criteria
- Set up radar and other electronic navigational instruments
- Radar is initialised and used in accordance with established procedures and manufacturer's instructions to assist in the safe navigation of the vessel
- Operational performance and accuracy of the radar is confirmed and appropriate action taken where performance is out of limits
- False echoes are detected and discounted
- Use radar and other electronic navigational instruments
- Radar and GPS/DGPS is operated in accordance with manufacturer's instructions to produce data on the position of other vessels and fixed objects
- Data produced by the radar and GPS/DGPS is interpreted and used to assist navigational command decisions, taking into account known limitations and errors associated with the equipment
- A radar plot is constructed on a radar plotting sheet using systematic radar observations
- Data on the radar plotting sheet is interpreted and analysed to anticipate potential collisions
- Information obtained through the analysis of the radar plots is used to make informed command decisions on action needed to avoid collision
