He said the US was the only country NOT using GPS and was totally outdated. So how, then, do the flights get to where they're going? GPS was used to guide the bombs to pre-determined fixed locations, which is a bit different than how it would work with aircraft. To use GPS for tracking an aircraft, the GPS device would be on the aircraft being tracked and it would have to broadcast this location information to the trackers. True, but GPS is GPS. They all use the same satellites. |

Some have advocated that. Most folks don't agree that's the solution. Virtually everyone involved in the system agree that the primary problem is ATC's in ability to manage the available resource. Hire more controllers. |

By flying different paths than now. Without moving runways, that's going to be difficult. Funny, GPS can place a smart bomb right on a target it tracks, but it can't track aircraft. GPS is a receiver-only system. It provides guidance to the aircraft in which it is installed. It provides nothing to anyone else, by design. I have news for you. I was on an international flight a while back and was talking to the relief pilot. He said the US was the only country NOT using GPS and was totally outdated. So how, then, do the flights get to where they're going? What your pilot doesn't know is that the FMS in every aircraft (almost) uses GPS as one of its navigation sources. The FMS uses GPS, VORs, ILS, ADF, and potentially whatever else is on the aircraft for navigation. So the U.S. is making heavy use of GPS. Still, this has nothing to do with _tracking_ aircraft by GPS, which is not possible. Ah, so you reduce shedules making them less convenient for the public, force aircraft to buy and sell aircraft they don't want, etc. etc. Brilliant. As fuel dwindles and CO2 increases, it will certainly seem so, although I rather consider it self-evident. |

Completely silly, of course. It's called redunancy. Redundancy won't help in a deliberate attempt. Check the web. Where you'll find out that 4 engined planes aren't anywhere near as efficient as two engined. Have much less fuel efficient engines,, etc. They don't have to have four engines to be big, and they are certainly not 100 times less efficient. Uuh. that was about 40 years ago ace when it was true. So things change. |

Snip Yeah, get rid of all the women and blacks. And take the stupid bigots with them at the same time. I did not say get rid of all the women and blacks. [...] The failure to see that the promotion of minorities and women into some key safety positions within the FAA was a mistake. Perhaps you can explain the difference between these remarks, and how they are not bigotted? Neil |

: "Allen" wrote AVIATION FUEL General Aviation Fuel Aviation gasoline: $0.193/gallon Tax Jet fuel: $0.218/gallon Commercial Fuel Tax $0.043/gallon Wow! I didn't know that the airlines paid almost no tax on fuel. Do the corporate jets get the same tax break, or do they pay the higher rate of .s28 per gallon? From your post, I take that they do not. How about the new light jet businesses that do the taxi type charters? The airlines really have balls complaining about others not paying their fair share, when they pay squat on fuel, and little on per seat taxes. Typical of their powerful lobby. It still ****es me off, though. Only the airlines pay no tax for fuel. All part 91 GA operations, which includes corporate jets pay. -- Marty Shapiro Silicon Rallye Inc.

Well a Citation CJ3 burns about 111 GPH at a tax rate of $0.219 that works out to about $24.31 per hour. While not not outrageous it isn't free. Do the airlines also pay this fuel tax? No they pay fuel tax at a MUCH lower level. |
