RYA Radar
1 day: £145
| The RYA Radar Training course is a one day entry level course will enable you to operate Radar equipment on board a vessel. Cruising boats increasingly have radar on board which is no surprise as Radar is probably the most versatile of all electronic navigation aids, but the best results are only obtained when you know how to use all the functions correctly. It is not an all seeing eye, and can easily mislead those who do not understand its controls, allow for its limitations, or interpret its picture.
Suggested Previous Experience None. Course Content You will be coached over the full RYA course syllabus and will gain an understanding of radar wave propagation, a detailed knowledge of the appropriate equipment, its function and correct use of controls. Types of Radar display, safety precautions, Radar plotting and Radar as an aid to navigation . Target characteristics, size shape and material. Radar reflectors. |

Syllabus Switching on and setting up The main components of a radar set. How a radar set measures distance. How a radar set measures bearing. The limitations imposed by the power, antenna size and display size of a typical small craft radar. Switch on a typical small craft radar set; adjust its brilliance, contrast, gain, range and tuning. Understanding the picture How antenna size and frequency effect beam width. How pulse length and PRF are varied with range. The factors that determine the strength of echo returned by a target. The effect of beam width on discrimination. The effect of blind arcs, shadows sectors and radar horizon. Refining the picture The cause and cure for sea clutter. The cause and cure for rain clutter. The cause and cure for interference. The purpose of echo stretch. The dangers associated with clutter clearance tools. The difference between Head Up, Course Up and North Up mode. Radar reflectors How radar cross section is measured. Types of passive reflector in common use (octahedral, stacked array, lens). Types of active reflector in common use (RTE, Racon, SART). The limitations of passive radar reflectors. Understands Collision Avoidance The principles of relative motion. The existence of automatic radar plotting aids. The implications of IRPCS Rule Numbers 5,6,7 and 19 (look out, safe speed, risk of collision, restricted visibility). The practical limitations of small craft radar. Assessing the risk of collision with another vessel. Assessing the closest point of approach of another vessel and determining whether it will pass ahead or astern. Assessing the course and speed of another vessel. Fixing position by radar The principles of a three point fix. Selecting landmarks for a three point fix. How to take and plot a position fix using the EBL. Limitations of the EBL for position fixing. Plotting the vessel`s position on a chart by using the VRM. Pilotage by radar Eyeball pilotage by radar. The limitations of eyeball pilotage The principle of parallel indexing. Preparation and executing a simple pilotage plan using clearing ranges.
