Radio fix

As a radio site (english radio fix) the determined by radio navigation current location of an aircraft or ship is called.

The wireless location results from Richtungspeilungen at least two NDB beacons that are mathematically with each other and the surface cut. Graphically, one determines the location, by transferring the bearings of a radio position lines (English line of position, LOP) on the map. Where these lines intersect is your position at the time of the bearings.

In the radio navigation all bearings (English bearing) or the price will be above ground (English track) basically stated as ill -looking directions ( engl. magnetic bearing, MB / magnetic track, MT) specified. The radio navigation map contains ill -looking courses.

Exception: Only the entries of radio position lines (LOP ) in the normal air navigation or chart is done with right -oriented courses, as these cards are aligned with the geographical meridians. The correction angle is the magnetic variation ( declination ).

Correction in the graphic: Angle RB1 runs from the direction of flight (TH ) clockwise until LOP1 and is 310 °. Consequently, in the bill is next door TH RB1 to put = TB: 120 ° 310 ° = 430 ° and 430 ° - 360 ° = 70 °
