That was just to provide an example of the type of ruthless, arrogant disregard for the rule of law members of the RNC have publicly displayed in the past. It's happening right under our noses now. Do you think there is the slightest possibility, that the "Decider" used the dirty trick of taking our nation into an unwinnable war in Iraq under false pretences just so he might be reelected? Why do you think Carl Rove left office? Gonzales, De Lay, Rumsfeld, Libby, ...; these people perpetrate the same old RNC dirty Nixon tricks today. Or haven't you noticed. |

wrote in : "Larry Dighera" wrote in message Are you aware that the FAA's intent is to decommission most of their radar once ADS-B is operational? ADS-B relies upon aircraft equipped GPS receivers; radar relies on the physical reflection of radio waves bouncing off of tangible objects. Which would you prefer to bet your life on? I'm not passing judgement on the ADS-B question, but relying on radar around the DC area can get you in trouble (if not killed). Radar plots can be as much as a mile off actual location, so I'm not convinced it's a superior alternative to satellite tech (like GPS) despite the occasional solar interference. Upon what do you base that allegation? Radar has been good enough to provide ATC positional information for decades. What has caused it to suddenly become anathema? When (not if) satellite communications go down, and the only means ATC possesses to update aircraft positions on their scopes goes with it, what will you say then? Reliance upon less robust technology as the basis of "upgrading" ATC only benefits those corporations that are in the business of fielding that technology. Try to look beyond the double-speak the Bush regime is vomiting, and think for yourself. The American people will be left holding the bag, something like draining our nation's treasure through the non-competitive contracts gifted to Halliburton and Blackwater. |

Yea, you are right. Thank you for admitting that you are completely unable to provide evidence of _ANY_ benefits to light GA operators who will be funding the lion's share of this proposed ADS-B "airspace modernization" boondoggle. Lets not modernize our airspace. Regardless of how much rhetoric is spewed about how NextGen ATC modernization will reduce airline delays, or provide better safety, the fact remains, that there is a _finite_ amount of airspace, so the system is inherently limited. No modernization scheme can change that fact. NextGen may enable reducing aircraft separation to some extent, but it is inevitable that a limit will be reached if airline traffic continues to burgeon. If you take a look at the NPRM and the FAA material on Next Gen you will see that it benefits GA much more than the airlines. I've looked at it, and I don't see what you are referring to. Perhaps you'll be good enough to provide an example or two. I dont know who you fly for, but the airlines already have many of the Next Gen procedures are in place. Can you be a little more specific? To what "procedures" are you referring? I dont mean to be sarcastic Larry, but when you fly an RNAV or RNP procedure do you long for the good old days of vectors and holding patterns ? ![]() FB Do you believe that ADS-B and NextGen are necessary for those procedures? I can recall using RNAV in the late '60s; it is not new. RNP is a result of more accurate technology. It is funded by those who use it, not those who don't. Incremental modernization like that is welcome. But to scrap the world's best ATC system in favor of large-corporation driven pie-in-the-sky marketing promises is foolish in my opinion. |

Any aircraft [owners] that choose to install ADS-B-in will benefit from all the other aircraft having installed ADS-B-out. Only in areas where air-to-air threats exist and see-and-avoid wouldn't work. Plus the cost to implement ADS-B In to include a suitable screen will be very expensive IF the FAA projected cost of over $17,000 just for ADS-B Out is even close to correct. You will never have the case where all GA aircraft have ADS-B Out installed. I have yet to see a credible argment for mandating ADS-B Out for GA aircraft. It is just emotional "we will all be safer" type comments that are not justified. Ron Lee |

The NPRM doesn't benefit those to whom it dictates the expenditure of larges sums of cash; it's for others. |

Upon what do you base that allegation? Radar has been good enough to provide ATC positional information for decades. What has caused it to suddenly become anathema? It's a repeat of what local controllers have told us in briefings and discussions about the DC ADIZ. This is the basis for the advice to keep your assigned transponder code for at least 3-5 miles when exiting the ADIZ (since squawking VFR inside the ADIZ is an automatic violation). We have been told there have been instances where pilots using GPS to identify the ADIZ boundary and squawking VFR (even after being instructed by ATC) were violated after "other sources" identified them as being inside the ADIZ. When (not if) satellite communications go down, and the only means ATC possesses to update aircraft positions on their scopes goes with it, what will you say then? Don't misinterpret my point. I'm merely pointing out that radar is not infallible and not necessarily more robust. Try to look beyond the double-speak the Bush regime is vomiting, and think for yourself. Ah, yes. The inevitable argument of many leftists. Just because I disagree with one minor point, I'm automatically in lockstep with your hated enemy, the Bush administration. Grow up, Larry. ...something like draining our nation's treasure through the non-competitive contracts gifted to Halliburton and Blackwater. More regurgitated left-wing propaganda.

Exactly my point. The NPRM doesn't benefit those to whom it dictates the expenditure of larges sums of cash; it's for others. That's approximately correct. Since "others" can include those dictated to spend that cash, it's not completely correct. But where's the surprise supposed to be? I rarely need the ATC service required by the airlines; my taxes pay for it anyway. Even at the airports I use, think of the waste of my tax money spent on all that extra runway I don't use (unless I desire several t-n-gs w/o bothering with the traffic pattern {8^). There are plenty of other examples, both government and corporate. In fact, though, I'm not sure you're right at all. If ATC costs drop as a result of this, then I get to see some savings in my taxes. Admittedly, the political classes will likely find a new way to spend my money, but they'd probably do that anyway (so I'm benefiting by having less taken from me {8^). Then there's the potential gain in safety in certain places. For example, there've been a couple of mid-air collisions at my "home" airport over the not-too-distant years. Most of the traffic pattern is shadowed from local RADAR by geography. But if the tower received an ADS-B-out generated "RADAR" display, controllers might be in a better position to warn even those non-ADS-B-in aircraft of collision threats. - Andrew |
