IFR with a VFR GPS

"Peter R." wrote in message ... Primary navigation (the VFR GPS) is no longer reliable, the aircraft is IMC, and the pilot is unaware that the unit is no longer reliable. Those are not properties of a problem? I don't think so. If the aircraft drifts off course the controller will nudge it back and the pilot will then be aware that the unit is no longer reliable. No problem. But chewing up TONS of radio time becomes a problem for all aircraft. On another thread, you argued that saying the extra zero for runway zero-nine takes up time. Now we're talking about taking up probably minutes of time. that I see as a problem especially if the controller then gives a clearance direct to a VOR/NDB that is not within range or is not in the database. That chews up serious amounts of more airtime. I've read many reports of controllers getting ****ed at pilots for not having waypoints in their certified GPS. I can only imagine what happens when pilot has nothing in their "database" other than a few points. For the pilot with the VFR GPS, your primary navigation becomes radar vectors. I'd rather know where I am at ALL time rather than depending on a controller. I know of one pilot getting RV in IMC, controller forgot about him and augered it in (CFIT). I can definitely see how a VFR GPS is useful when flying enroute and VMC with loads of VOR's for use as a backup (err, primary navigation). To do it, single pilot, in IMC, just has many single point failures or where you have backups but requires a lot of work to get positively established/stabilized again. Gerald Sylvester |

Peter,
Assuming the pilot is continually tuning his traditional navigation radios, then including those in his instrument scan. And what if he does not? Then he doesn't adhere to the rules. That's like asking: What if the pilots points the airplane at the ground? -- Thomas Borchert (EDDH) |

Peter,
I am going to maintain that premise because even more unthinkable, someone was actually killed flying a GPS approach with nothing but a VFR GPS. I So what does that show? People do stupid things in airplanes all the time. Are you suggesting flying should be prohibited because of that? -- Thomas Borchert (EDDH) |

I was merely identifying one risk of using a VFR GPS, not stating that everyone who flies with a VFR GPS does not use all available information. Isn't this also true if you fly airways but DON'T use a VFR GPS? JKG |

That is not RAIM which determines if you have a signal error. Just to clarify, are you saying that a *VFR* GPS's screen flashes when the GPS loses the required number of satellites for position calculation and that error is not a result of built-in RAIM? When my hand held Garmin loses enough sats for position calculation, I receive an alarm on the unit (both visual and audible). I believe that RAIM performs a checksum to verify the integrity of the data received from the sats. Hand held devices are indeed missing this functionality, but it makes no difference for enroute, in my opinion. JKG |

Pointing the aircraft at the ground is not analogous to using a VFR GPS to navigate. Besides, what rule is broken by pointing the aircraft at the ground? -- Peter ----== Posted via Newsfeeds.Com - Unlimited-Unrestricted-Secure Usenet News==---- http://www.newsfeeds.com The #1 Newsgroup Service in the World! 120,000+ Newsgroups ----= East and West-Coast Server Farms - Total Privacy via Encryption =---- |

Peter,
Besides, what rule is broken by pointing the aircraft at the ground? 91.3, of course ;-) -- Thomas Borchert (EDDH) |
