A couple things:mgh, your diagram is incorrect because it is not possible for the nav indicator to show a "to" flag when tuned to 090 when the aircraft is anywhere east of the station, since tracking 090 would actually take you from the station.The aircraft is southwest of the VOR. Glenn, If you were to switch the OBS around to 270, the to/from flag would indeed switch over to "from", BUT the needle would also swing over to the right side of the display.I found a java VOR trainer using google. Everyone can try your theories out on this.http://www.visi.com/~mim/nav/Ok, now for something I noticed in CowlFlaps's original post but dismissed earlier as an error in terminology. It may be a simple question or a trick question depending on what he means when he says "radial."He says you have the 090 RADIAL tuned in and asks how can you intercept the 090 RADIAL. First of all, to use precise terminology, you do not tune in a radial on the OBS, you tune in a course. Technically it is kind of incorrect to say you have the 090 radial tuned in. You actually have the 090 course tuned in. Then, depending on what side of the station you are on, the CDI is telling you your deviation from the actual radial of the course tuned in ("from" flag) or it's reciprocal ("to" flag).The 090 radial only exists on the east side of the VOR. The term "radial" only refers to courses from the VOR, not to. However, people often make the mistake of saying that they are dialing in a "radial TO the station." I assumed that CowlFlaps made this common error, especially when he also put in parentheses "on the course index", and when he asks what direction you would turn "to intercept the radial" I assumed he actually just meant he wanted the needle centered. In this case, if you turned right to 360, the needle would eventually center, and you would be on the 270 radial.If, in fact, the question is "from the given information, how does one intercept the 090 radial?" then there are a few ways, all technically correct. You could turn left to 090, fly east until the to/from indicator flips to "from", then turn left to a northeasterly heading to intercept the 090 radial.You could also turn right to heading 360, intercept the 270 radial and track it inbound to the station, then once you pass it you will be on the 090 radial. You would leave the OBS on 090 the whole time, because to track a radial inbound to the station (270 in this case), you tune its reciprocal in the OBS.You could also turn right (or left, but right is a shorter turn) to some northeasterly heading and fly it until the needle centers. In this case, the needle may center before or after you pass the station, but in either case you will eventually be on the 090 radial.*takes a drink of water and caps the dry-erase marker*Ok, I think I have all the bases covered here. My question to Cowlflaps is, were you trying to trick us with that terminology, or did you really mean "course" every time you said "radial"?
