![]() "Steve House" wrote in message ... Student here, following debate with interest but I don't understand the issue at disagreement. Considering "bearing" as distinct from "relative bearing", is not the bearing the clockwise angular direction with respect to the meridian over its origin of a line drawn from one point to another? And since the 0 radial of the VOR station is aligned to the magnetic meridian, each VOR radial indicates directly the magnetic bearing from the VOR station to an object that lies somewhere along it. To get one's bearing from the VOR station, than, can you not just rotate the OBS until the needle is centred? If the "from" flag is up then the OBS ring reads out directly the magnetic bearing to the aircraft as viewed from the VOR station, and if the "to" flag is up, the OBS is showing the reciprocal. So don't you know you're somewhere along that line? Yes. That was my point exactly. Only, somewhere along that line could be anywhere within about a 200 square mile area when you factor in the inherent accuracy of the single VOR. Of course, neither indication gives the actual aircraft position without using some other additional means to establish distance from the station - DME, triangulation on another station, etc. Yes. That was my point exactly. |
