A [http://en.wikipedia.org/wiki/Non-directional_beacon Non-Directional Beacon ('''NDB''')] is the most basic type of radio beacon. The equipment on board of our aircraft will have to figure out where it is. Any (music) radio station is also a NDB. The typical frequencies of a NDB can be found on the [http://en.wikipedia.org/wiki/Medium_wave AM Medium band] (530 kHz to 1700 kHz) but during flight planning we shall discover NDB's outside this range. | A [http://en.wikipedia.org/wiki/Non-directional_beacon Non-Directional Beacon ('''NDB''')] is the most basic type of radio beacon.
