m... It might be interesting sometime on a VFR day to fly this with the localizer on its last dot (just barely not pegged) and also on the last dot of the glideslope, just to see how much room that really leaves you. Maybe I'll try it in Flight Simulator tonight just for kicks. I tried it on FS2004. At full deflection, you certainly come close to a smokestack, but you don't hit it. (Of course, the FS2004 scenery shouldn't be trusted for real-world purposes, though it looks correct here.) --Gary |

m... I wonder how many of those CFIT accidents where the aircraft was inexplicably off the FAC are actually a result of this. I also don't think it's such a big deal anymore, because nobody I know flies IFR without GPS, be it IFR certified or not. I do. There's no GPS in most of the IFR planes I rent (but they do have VFR LORAN). --Gary |

Hm, the VOR could even be off by 6 degrees (for an in-air check) and still be legal. In that case, even one dot of deflection could be lethal on that approach. Quite true. The scary part is I almost killed myself and a student that way. We had a lesson one morning, I called for a briefing, and there were two airports reporting IFR conditions. LVJ was the closer one, so we went there (I'm a big believer in training in actual whenever possible, even if it adds time to the lesson - owners tend to be OK with that since they're just paying for gas) and the only approaches were VOR and GPS. The plane had no GPS, but the VOR was fine. We got about 30 minutes of actual on the way out, but then the weather started breaking up. Still, by the time we broke out we were being vectored to the FAC so I had the student put the hood on and continue. He was doing a fairly credible job of it (the air was bumpy) meaning he was well within PTS standards at all times. And so I sat there and watched as he performed an approach that should have been fine - and I saw us head for a tower. Had we been in IMC, there is an excellent chance I would not be here. After this, we performed a VOR check in the air on this VOR. The VOR showed 5 degrees off. In other words, it was legal. We later checked it in the air on another VOR. On that one, it showed 2 degrees off. Michael |
