4.3.1. Tim's Air Navigation Simulator
This is a Java applet that simulates the operation of ADF and VOR
instruments. A canvas shows the position of a hypothetical aircraft and
two ground based navigational aids, (which can be dragged to arbitrary
positions with the mouse). The instrument display shows what the pilot
would see in the corresponding situation. The applet code is available
for download if you want to install it on your own machine.
