A | 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. | ||
It ''is'' possible to calculate the distance towards a NDB station. For that a pilot flies on a 90 degree angle opposite the station (one wing-tip pointing towards the station). The pilot measures the time it takes to fly a number of degrees on the compass. From the time it takes, the number of degrees and the ground speed the pilot can calculate the distance towards the station. | It ''is'' possible to calculate the distance towards a NDB station.
