Fixes provided in routing for IFR flight plans - VFR waypoints okay?
Although lat/long is technically acceptable, my experience is ATC
doesn't like them and dont know where they are. Also, they don't know how to call them out. ATC prefers VOR/DME, which you can use the GPS to find if you know how. But the best thing IS VOR's or airports. Although intersections SHOULD be ok, I've seen ATC not know where some are. The VFR waypoints are excluded, I guess they didn't want to go there. Best thing these days seems to be to file direct and take what you get UNLESS you fly it all the time and KNOW what ATC is going to give you, in which case, file THAT. It's a bit of a quagmire and I've filed one route, gotten my ground clearance for a second route and then once in the air, been told to fly a third. Which is why I just file direct (which is the fastest anyway). |

With intelligent preflight planning and intelligent use of RNAV, the odds of SAR finding a downed VFR aircraft aircraft are very good especially when the ELT doesn't work. If I put specific waypoints on my VFR flight plan and fly them, I'd expect that SAR would be able to go directly to the point where I went down, or nearly so. That's a lot easier and faster than searching thousands of square miles. -- Transpose mxsmanic and gmail to reach me by e-mail. |

SAR is not going to be able to go directly to the point where you went down. All they know is when where you started from, where you were going, and how you were planning to get there. When SAR is initiated 1/2 hour after you don't arrive, they have the entire route to search. But, at least they have a route to search. The closer to the center line of that planned route you are when you go down, the better the odds of them finding you. Lat/long fixes or formal NAVAID fixes, it doesn't really matter. -- ------------------------------- Travis Lake N3094P PWK |

They know all the position reports I made, too. So they should be able to extrapolate from my last position report and narrow things down considerably. The closer to the center line of that planned route you are when you go down, the better the odds of them finding you. Lat/long fixes or formal NAVAID fixes, it doesn't really matter. Which is where RNAV comes in handy. I would tend to favor RNAV for any long flight, even VFR. I can look out the window and see if the scenery matches what I expect based on the navigation. -- Transpose mxsmanic and gmail to reach me by e-mail. |

For VFR flight plans LAT/LON has a huge advantage over published fixes in many parts of the Western U.S., both to avoid restricted areas and remain in valleys (ala Eastern California, most of Nevada, and other states with similar topography. |

I sometimes fix up user waypoints for precisely this reason. When you can't fly at FL340, it's handy to be able to plan a route that avoids really high terrain, but the official waypoints are sometimes too thin on the ground to serve the purpose. -- Transpose mxsmanic and gmail to reach me by e-mail. |

SAR is not going to be able to go directly to the point where you went down. All they know is when where you started from, where you were going, and how you were planning to get there. When SAR is initiated 1/2 hour after you You are making an optimistic assumption that SAR is going to be initiated a 1/2 hour after you don't arrive. Real case in point. I arrived at Lee Gilmer Memorial (KGVL) NE of Atlanta around 11:00 PM. The phones weren't working. It was something line 2 or 3 hours later before I actually was able to contact FSS (I could have driven in and knocked on the door faster). to close my flight plan. I apologized for being late. The comment was something to the effect of "Late? Oh, yah, I guess you are a little on the late side". IOW in some cases SAR may not even be alerted unless some one calls and wonders where you are. don't arrive, they have the entire route to search. But, at least they have a route to search. The closer to the center line of that planned route you are when you go down, the better the odds of them finding you. Lat/long and those odds are pretty poor if most of the route is heavily wooded terrain. It's fairly well populated around here. A Bonanza went down headed for MtPleasant. It's less than 20 miles from Midland to Mt Pleasant. The pilot and copilot had walked out of the swamp and called well before the plane was found. OTOH it was snowing like made. They went directly over our house and went down about 6 miles west or here. fixes or formal NAVAID fixes, it doesn't really matter. With a flight plan AND flight following they are more likely to know where you might be as the loss of transponder signal normally gets their attention. Coming out of Kansas scooting under some really nasty stuff I had precipitation static build up to the point where I had to cycle the electrical system. As I recall they were calling me when the radios came back to life. However in *some* areas FSS is far more alert to over due aircraft than others. Due to Denver ATC rerouting me around some *areas* and threading our way between clouds containing tornados and giant hail I was a bit behind schedule arriving at Jefferson County, Jefco (BJC). I made certain to call as soon as we were on the ground. They were still upset as I was pushing the limits. I hate to burst that warm and fuzzy feeling bubble :-)) but SAR may not even be notified until the next day depending on conditions.

Roger Halstead (K8RI & ARRL life member) (N833R, S# CD-2 Worlds oldest Debonair) www.rogerhalstead.com The classic case for SAR not finding a downed aircraft is the Lear which crashed on an ILS approach to LEB (Lebanon, NH) on December 24, 1996. The wreckage wasn't found until November 11, 1999. --- Marty Shapiro Silicon Rallye Inc. (remove SPAMNOT to email me) |

When SAR is initiated 1/2 hour after you You are making an optimistic assumption that SAR is going to be initiated a 1/2 hour after you don't arrive. I understand. As usual, I over-generalized an important fact in my haste to make a different point. To summarize the points that I agree with in this thread: 1) Lat/Longs or other RNAV waypoints are fine for VFR fixes in a flight plan. Nobody is going to look at them until it's necessary anyway. 2) Lat/Longs or other RNAV waypoints will allow you to fly as directly to your destination as possible while avoiding obstacles/terain/airspace and still give ATC and SAR a clear definition of your flight path. 3) Position reports on a VFR flight plan increase the likelyhood of being found quickly by SAR Conclusion: None of the above is worth it to me. I sure as heck am not going to plot out lat/longs and program my GPS with them. Kind of takes the fun out of flying VFR, doesn't it? ------------------------------- Travis Lake N3094P PWK |

IOW in some cases SAR may not even be alerted unless some one calls and wonders where you are. No doubt about it. A prudent course of action is to have someone who gives a damn about you to make the wakeup call. But, once that is done, SAR will benefit greatly from a precise VFR track. |
