Détermine la distance à un NDB ou VOR à partir d'une solution définie par deux QDRs
Determines the distance to a NDB or VOR from a fix defined by two QDRs (or two radials) from two stations (NDB/NDB or NDB/VOR or VOR/VOR).
Enter the two QDRs which define the fix and also the magnetic bearing and the distance between the two stations.
