Let's say you lack RNAV, and your destination airport has an off-field VOR approach, no DME, and no other nearby navaid. How would you propose to use that airport as a holding fix if you're going to hold for an hour? I don't! As I wrote previously, the decision to hold or not is situation-dependent. The situation you describe would prompt me to squawk 7700/7600 and shoot the approach on arrival. So then, Weiss remains incapable of learning. |

news:00ePb.89430$Rc4.449664@attbi_s54... "Steven P. McNicoll" wrote... In most cases the clearance limit is the destination airport, how do you comply with FAR 91.185(c)(3)? Easy -- per 91.185(c)(3)(ii). Holding over the airport would be a Standard pattern per AIM 5-3-7.c. But if the clearance limit is the destination airport, then there won't be and EFC, and so 91.185c3ii does *not* say to hold over the airport. Suppose you lost comm shortly before getting to an IAF, and before being cleared for the approach. In that case, compliance with 91.185c3ii as written would require you fly from the IAF to the airport, then back to the IAF, then back to the airport to land. Is that what you would do? Since compliance would be nonsensical, it seems clear that 91.185c3 just wasn't intended to address the case where the clearance limit is the destination airport. --Gary |

Another thing we learned on that flight was that handhelds aren't worth crap inside the airplane. Hmmm, based on our testing I wouldn't say that. First, hearing anything over the cabin noise was very difficult (neither of us had adapters to plug our headsets into the handheld radios). Second, the little rubber ducky antennas don't work for ****, especially inside a metal airplane cabin. Ah. Well, yes, one definately needs the adaptor for the headset. Another thing which is helpful is an adaptor cable with suction cups, which allows one to place the antenna on the windshield. It might also help that our plane probably has less metal and more window in the upper half of the cockpit. With the above, what we discovered in an afternoon of testing is that it worked OK in areas where radio reception was strong, but not nearly the same range. No surprise there. What I think would make the most sense is a way to connect your handheld directly to the external antenna in the plane, and make sure you've got a way to plug your headsets directly into your handheld radio. Yes, that would definately make the most sense. It's also very useful to have the headset adaptor and anything else which needs setup, already set-up. If one needs the handheld the last thing one needs is to be fumbling about trying to set it up. Cheers, Sydney |

"PaulaJay1" wrote in message ... No, Steve, I don't think the controller should have to jump thru hoops several times a minute, either. The SYSTEM should allow you to disable MY 7600 after you have seen and heard it and let me continue the code and still be armed for another if it occurs (surely you don't get many overlaping emergencys). It just seems that to put in 7600 and then return to my original (requiring me to remember it) in 30 seconds is unnecessary load at a critical time. How would the system distinguish between your 7600 code and another 7600 code? |

"John R Weiss" wrote in message news:vHfPb.91560$5V2.229832@attbi_s53... I was under the impression you were an instrument-rated pilot as well as an ATC controller... I am. Direct, using the time/heading/distance from your preflight planning. Ah, via dead-reckoning. I see. Are you an instrument-rated pilot? Are you a pilot at all? [From the question, I assume MKE doesn't have a VOR at the field. I'm in Seattle, and don't have charts or other pubs for the MKE area, so I'll fast-forward you to WA.] Online versions are available, MKE is on the NACO IFR Area Chart Chicago/Milwaukee. If I was enroute to BFI (Boeing Field, WA, which does not have a co-located VOR), I would know to look up the nearby NAVAIDS in the Airport/Facility Directory, and find that BFI is at the SEA 341/5.7. I would plot the course and distance from my previous waypoint (e.g., TAGOR, on V 120, SEA 069/16) on a Sectional, and transfer it (approx 291/17) to my kneeboard Nav card. In the airplane, if I lost comm prior to TAGOR, all I have to do is fly direct from TAGOR to the SEA 341/5.7 (cross-checking with the PARKK NDB at the field, if I don't have DME -- I could do this as an NDB hold, too, but I am assuming that isn't an option at MKE), using the preplanned heading and time, adjusted for any wind corrections I'd been using enroute to TAGOR. Nope, not an option at MKE. Given that you can navigate enroute and hold using just dead-reckoning, why do you bother with navaids while enroute at all? |

"John Harper" wrote in message news:1074631707.427512@sj-nntpcache-3... This all strikes me as highly academic. The only likely reason for losing both comms is an electrical failure. In that case you're on the mag compass and dead reckoning, if you're in IMC. The only good reason for knowing the official lost comm procedure is to pass your instrument oral. Well, dual communications radios are not required for IFR operations, but you're essentially right. In a typical avionics package in any aircraft used regularly for IFR transportation there are at least two communications radios. If the installer did his job right they share no components and he provided auxiliary jacks in the event of an audio panel failure. Most pilots today seem to prefer wearing headsets, but if there's a problem with the headset the cabin speaker and hand microphone are there. The chances of losing both transmitters and both receivers simultaneously are extremely remote, unless the loss is due to a failure in the electrical system, which would leave the other installed avionics just as useless as the comm radios. |

"John R Weiss" wrote in message news:_biPb.92428$5V2.241427@attbi_s53... If you can navigate to a place once, you can do it again. If your navigational ability is so degraded that you cannot find your position via VOR/DME, VOR/VOR, VOR/NDB, or similar means, then you probably should declare an emergency and navigate any way you can to any place you can identify. Have you given up on dead-reckoning? |

"John R Weiss" wrote in message news:BskPb.93571$5V2.266461@attbi_s53... I don't! You did less than a day ago: Okay. I'm heading to Milwaukee from Grand Rapids. I've filed the preferential, GRR..MKG.V2.SUDDS..MKE, and have been cleared as filed. I'm flying a BE35/U; two nav/comms, GS receiver, ADF, and marker beacon receiver. At MINNY I discover I cannot transmit or receive on either comm radio. How do I hold over the airport? Per AIM 5-3-7.c: Over MKE Standard pattern (right turn, 1 or 1 1/2 minute legs) On the course from SUDDS to MKE At your cleared altitude Until the time calculated per 91.185(c)(3)(ii) |
