I will also move the plane to a random area and try to work out where I am using VORs,
Nice idea.
or navigate using VORs/NDBs great to be able to pause and consider why the needle is doing what it is doing.
What I found very helpful in learning how VORs/NDBs and the like worked, is putting the game in "slew" mode, which effectively pauses the game and "hovers" the aircraft. Very useful for positioning the aircraft exactly where you want it, rotate it, and see what happens to the needles (or not).
