There's a lot to know about using an ADF (automatic direction finder) to track an NDB (non-directional beacon) ground station, so we've adapted diagrams from our Flight Training book into this poster. It covers the details of the ADF instrument, ADF readings based on position, determining magnetic bearing to station using both fixed and moveable card ADFs, and intercepting & tracking a bearing to or from an NDB ground station.

Why not use one of our museum-quality posters, made on thick and durable matte paper, to add some inspiration to your room, flight school or office?
