It certainly gives you some. ;-) Thanks for clarifying what I meant Peter :-) Though when I think about it, my VFR training required a diversion to another airport. My IFR training did not require it. Wonder why that is? Both scenarios play out the same, finding the airport and navigating to it..... Maybe something to consider for future IFR students? Allen |

More IFR with VFR GPS questions

How did you intend to do that if you were unable to accept a reroute to something other than a standard VOR or intersection? Precisely my point Steve. ??? Even though I filed direct, off airwaves, ATC recognized my limitation that I could only accept a standard VOR or intersection. Surely you could accept an airway? What else would you expect ATC use for a reroute, other than VORs, intersections and airways? It was NOT assumed by ATC that I had GPS capability even though I filed direct. I think it likely that ATC did assume you had GPS capability precisely because you filed direct. They have to assume that you have the capability to fly what you filed and at this time it is GPS that is most likely to give you that capability. Had they given me a GPS intersection rather then a VOR or VOR associated intersection, I would have said unable, alerting them to the fact I am slant Alpha. That was the point I was trying to bring across in my original post. What is a "GPS intersection"? YRK vortac is 148 miles southwest of 2G2. Do you believe there's something wrong with being routed over a VOR that far away? Considering there are quite a few VORs closer then YRK, I was not looking that far down the road in establishing where I am to where I am going. I was looking within 45 to 60 miles, not so far down the road. I am situationally aware of what my next VOR will be when I fly IFR, as I have them printed as well having the en route maps open. I also change my NAV 1 and NAV 2 as I progress in my flight path to assist in my situation awareness. The problem I had as slight as it was, was finding the frequency to the VOR. Wasn't in the list of nrst on my Garmin 296, and being in IMC, it's not exactly conducive of finding a navaid on the paper maps especially 90 odd miles away. I wasn't given a vector, just direct York, direct Bowling green, so I did not know what direction to look on the en route maps. Had center given me a vector, I at least would have known which direction to look. I would have expected a closer VOR, not one 90 miles away to go direct to. As you can see, not that big a deal, but for a person like me, learning the ropes of IFR, when I am by myself, I don't have CRM available. Small things do make a big difference. Did you examine your chosen route at all when you were planning your trip? Almost halfway between 2G2 and BWG lie a couple of MOAs, your filed route goes through them. Just a few miles south of the MOAs is York VOR. Your reroute was probably necessary because the MOAs were in use. |

More IFR with VFR GPS questions
"S Herman" wrote in message ... First off I am an instrument student, not yet rated. I have a lot more marine navigation experience than aviation IFR experience, but let me throw this out. It seems possible to me to fly direct between most any 2 points, off airways, without vectors, using 2 VOR's and a sectional chart. Just plot a series of radial intersections at appropriate distances from each other to ensure remaining close (for gov'ment work) to the desired direct track. Is this illegal? No. Or is it just that you won't get a clearance using this method? You can get a clearance using that method. ATC cannot know what you're using for navigation unless you tell them and there's no reason for them to ask. I am assuming that the direct course & altitude would be within reception range of the (2) needed stations. Then what's the point of plotting a series of radial intersections at appropriate distances from each other to ensure remaining close to the desired track? The desired track would be the two radials that define a direct course between the two VORs. This would require a bit of OBS twisting for sure. It would require you to select the outbound radial from the first VOR and the inbound radial from the second VOR. You would use your VFR GPS to reassure yourself that you are on that desired track. If anyone asks, your primary means of navigating were by use of VOR's. If you have a VFR GPS why bother with a course between two VORs? |

"Jose" wrote in message m... I don't know if it is legal or not (that would be up to the FAA, after the accident), but it would be impractical. I have almost never flown an IFR clearance that I have carefully plotted at home. The clearance I get is different, and there are numerous reroutes enroute. Imagine being in bumpy air in the soup, and given "direct WAYNS". You are somewhere between two VORs flying an airway. Ok, with an intersection you can figure out pretty much where you are, now try plotting it on your lap on a sectional, crossing from front to back, going over three creases, bumping along in the clouds. Betcha can't even draw a straight line, let alone calculate points along it. If you filed via airways and with an equipment suffix that does not indicate any RNAV capability you should not be told to proceed direct to an intersection. If you are just respond "Unable." |

What else would you expect ATC use for a reroute, other than VORs, intersections and airways? Obviously airways start and terminate from an intersection or VOR. I would have assumed you would have understood what I meant. But then assume does have another defintion I guess. If I have to fly to a VOR via a certain radial, to pick up an airway, no big deal. Point I am trying to drive home is that ATC did recognize I was slant Alpha. I think it likely that ATC did assume you had GPS capability precisely because you filed direct. They have to assume that you have the capability to fly what you filed and at this time it is GPS that is most likely to give you that capability. I'd think you were incorrect on this. They sent me to a VOR. Doesn't the flight strip show what I filed?

That was the point I was trying to bring across in my original post. What is a "GPS intersection"? Since I don't have an IFR GPS (yet), maybe I worded it rather poorly, but are there not other routes that GPS may offer then standard NAV routes?

Just a few miles south of the MOAs is York VOR. Your reroute was probably necessary because the MOAs were in use. Please re-read what I wrote above. As I originally posted, the MOA's were hot, and the re-route was due to the MOAs. I would have expected a clearance to a VOR closer to where I was and then if needed run the airways until I am cleared the VORs. Don't get me wrong, the clearance I received was much simpler then it could have been, which I am gratefully thankful for, being a single pilot in IMC. I just would have expected a clearance to a fix within a range that at least I could have picked up on the nrst function of my GPS, not some 90 miles away. Allen |

"A Lieberman" wrote in message ... Obviously airways start and terminate from an intersection or VOR. I would have assumed you would have understood what I meant. But then assume does have another defintion I guess. I've learned it's best not to assume anything here. If I have to fly to a VOR via a certain radial, to pick up an airway, no big deal. Point I am trying to drive home is that ATC did recognize I was slant Alpha. Of course they did, it's right on the strip. But they also recognized you had RNAV capability based of your filed route. I'd think you were incorrect on this. Why? They sent me to a VOR. They sent you direct to a VOR that was out of range. Doesn't that suggest to you that they assumed you had RNAV capability? Were you originally cleared as filed or via radar vectors? How could they clear you as filed without assuming you had RNAV capability? Is there another fix that would have provided sufficient avoidance of the MOAs with less deviation than YRK VORTAC? Doesn't the flight strip show what I filed? Yes, it wouldn't be very useful if it didn't. Since I don't have an IFR GPS (yet), maybe I worded it rather poorly, but are there not other routes that GPS may offer then standard NAV routes? An intersection is a point defined by any combination of courses, radials, or bearings of two or more navigational aids. I believe you're thinking of waypoints. Please re-read what I wrote above. As I originally posted, the MOA's were hot, and the re-route was due to the MOAs. I would have expected a clearance to a VOR closer to where I was and then if needed run the airways until I am cleared the VORs. A re-read confirms you didn't mention the MOAs. If you knew the MOAs were hot why did you file a route through them? I just would have expected a clearance to a fix within a range that at least I could have picked up on the nrst function of my GPS, not some 90 miles away. Well, there's no reason to expect that. |
