Here is a very cool navigation simulator, provided by
Luiz at www.luizmonteiro.com,
that shows how the dials and needles on the navigation instruments
move as an aircraft flies around...
essential knowledge for navigating at night or in cloud.
This simulator uses the Flash plugin... if the simulator is not displayed below try reloading the page.
(* the videos require the Quicktime plugin... if you don't already have this it is available from here)
Click the dot in the TOP RIGHT of the sim to see the keys that control the plane...
