Radar Navigation, Radar Plotting and Use of ARPA
The course aims to meet the mandatory minimum requirements for knowledge, understanding and proficiency in Table A-11/1 of STCW 1995. The aspects covered include the theory necessary to understand how radar information is obtained and displayed, the limitations and accuracy of that information, the formation and recognition of unwanted responses, the correct use of operational controls to obtain an optimal display and checks on performance of the set.
The course covers the recognition of critical targets, the measurement of bearings and distances, and the use of these for fixing the ship's position and maintaining a plot of the movement of other ships as an aid to collision avoidance. Exercises in the application of the International Regulations for Preventing Collisions at Sea (COLREG) make use of the resulting plots.
The course complies with the requirement based on the guidance on training in radar observation and plotting and in the operational use of ARPA in Section B-1/12 of the International Convention on Standards of Training, Certification and Watchkeeping for Seafarers, 1978, as amended in 1995 (STCW 1995). This model course aims to meet the minimum training standards in Table A-II/1 of STCW 1995. This guidance supersedes the recommendations annexed to Resolutions A.482 (XII) and A.483 (XII) adopted by IMO in 1981.
This course is open to candidates for certification as officers in charge of a navigational watch.
- Before entering the course, trainees should have completed a minimum period of six months at sea and preferably have gained some experience of bridge watchkeeping.
