Have any WAAS LPV approaches been established for runways that do not already
have an ILS in place? I'm presuming the limiting factor is LPV deployment is clearing the approach airspace, lighting, runway length rather than drawing the approach plate... Does the FAA publish its priorities or a schedule of new/improved approaches? -- Shiny new 430W |

![]() Have any WAAS LPV approaches been established for runways that do not already have an ILS in place? Yes. In my neck of the woods, TCY, C83 and HAF come to mind. Does the FAA publish its priorities or a schedule of new/improved approaches? I don't know. Shiny new 430W Enjoy! |

Since you want the info, and unless you want to hire at a
decent wage, you'll have to do a little research. Might I suggest, Google's site search feature... www.faa.gov www.firstgov.gov You can also check www.aopa.org www.nbaa.org and your Congressman's office gets paid to answer questions from constituents. BTW, the link I posted IS just what you wanted, you obviously didn't bother to look at it.

Does the FAA publish its priorities or a schedule of new/improved approaches? -- Shiny new 430W Most LPV IAPs that have been published to date are not to ILS runways. There are strict airspace issues, similar to an ILS. No course change at the FAF unlike other RNAV. Parallel taxiway. GQS (glideslope qualification surface) a very strict obstacle-free area inside DA to the runway. No lighting required for daytime. ALS are optional for reduction in visibility. Production plan for all IAPs: http://avnweb.jccbi.gov/schedule/production |

There are LPV approaches at airports that do not have an ILS. A local example for my area is at KAKH. John, thanks. Your links were quite useful. As it turns out there are (as of the August report) some 516 LPV approaches to runways without an ILS and 295 to airports with no ILS at all. I am pleasantly supprised that the WAAS approachs are moving along. Thanks again, Doug |

I am pleasantly supprised that the WAAS approachs are moving along. ISTR they had stepped up production in the last couple years, and are now cranking 'em (all types of WAAS approaches) out at a average rate of around 100 per cycle. Thanks again, Doug It's worth pointing out that AVN may update the site at some point to distinguish between the existing LPV (250ft. DH) and a newer type of procedure (LPV-200) which is on the horizon. Also, it's my understanding that, in some cases, there may be a mix of the two procedures at some airports (for example, LPV on one runway end, LPV-200 on another). Regards, Jon |

Around 9 new ground reference stations have gone on line and the WAAS system software has been upgraded. Now the 200 ft LPV coverage area covers most of the country. Indeed. And this is important as there's something on the order of a couple thousand TSO-ed receivers out there now, so the system is being used so much more than when it IOC in '03. The WRSes in Canada, Alaska, and Mexico[1] helped to improve the service volume, as did the code releases from Raytheon. Repositioning one of the GEOs and adding a 3rd also help with coverage as well, as the GEOs provide a (GPS-like) ranging source in addition to being their primary purpose of being an uplink for correction/integrity info. [1] The WRSes in Mexico aren't certified everywhere yet (e.g. not to be used up in Canada). Seehttp://www.nstb.tc.faa.gov/RT_VerticalProtectionLevel.htmfor near real-time coverage. Good linkage. The Tech Center (Atlantic City) is THE definitive source for, among other things, all things WAAS Signal-in-Space (SIS). They have been collecting SIS for at least a decade and know more about all . We use(d) them as the "Truth Source" for validating our SVM prediction model. Bill Wanner and his team are good people, all quite competent in the field. It's fun attending meetings there, as there's a fighter wing next door, and when they practice touch and go's on the TC's runways, the windows in the conference room warble ![]() Some general eye candy - albeit somewhat PR-ified, but better signal/ noise ratio than you might find from the typical media links with which some seem to have an undying love affair ![]() going on at the TC, including a (dated) high-level blurb on WAAS (CNS video), can be found at: http://www.faa.gov/about/office_org/...ffices/ato/tc/ tc_videos/ Apologies for the brain-dead wrapping that Google is sure to have done to the above link. Just splice the two pieces into the browser's maw and you should be good to go. -- Regards, John D.

Apologies for the reply-to-self. Pulled the Send trigger a little to
quick: On Oct 31, 11:39 pm, Jon wrote: They have been collecting SIS for at least a decade and know more about all . the details that are hapeening inside tho various 250-bit WAAS messages continuously being broadcast, than just about anyone. To be fair, some folks at Stanford, FAA, and of course, Raytheon, are right up there as they were all key players, from Requirements on through to Deployment; but the group at the TC are the ones that ran the initial flight certification trials, ran the 60-day stability test prior to IOC, and continue work with the bits/bytes day in and day out. The periodic PAN reports are available for those that want to dig deeper down, and perhaps for others that may have trouble falling asleep at night ![]() Regards, Jon |
