How to Use RT3

This program includes various land masses for studying chart navigation with radar. It also includes moving targets for additional practice. The program has two primary screen views, the Chart view and the Radar View, which are illustrated below.

RT3 Chart View with Scan on

When you first start Radar Trainer 3 it is running in the Chart View on a default chart with default traffic. It will always start in exactly the same manner and mode. There are 3 vessels set, a "center vessel," whose radar you are observing, and 2 active targets. The targets show up as red dots on the chart leaving gray trails behind them. In the small radar screen, the plot option is turned on which leave purple trails on the radar screen. The simulator is running with a time factor of 3, which means the action is evolving 3 times faster than it normally would for the speeds assigned to yourself and the targets. You can vary the time factor from real time (factor 1) up to a factor of 10.

If you care to see on the chart the region you are viewing on the radar, press the Scan button which will show as a green sweep on the chart precisely what the radar sweep is interacting with. The controls on the bottom left are used to drive the center vessel, the pan and center buttons on the bottom right are used to move about the chart window. Traffic is set on the chart window by drag and drop from the Set Vessels window (not shown).

RT3 Radar View

In Radar View the radar screen fills your computer screen. This is the view that must be used for the practice exercises in navigation and piloting. For each land region simulated, there are pdf versions of the charts that can be printed and used for reference as you navigate with the radar.

The full Radar Trainer 3 package contains many resources. The best bet is to skim through the introductory parts of the Help and Tutorial. This will acquaint you with the simulator and the various resources. There are organized Lesson Plans, as well as a set of Practice Exercises with answers. If you cared to, you could go straight to the exercises to work with them and from there learn what areas might need some review and then turn to those specific sections of the Tutorial.
