Hello Skip, How WAAS works is a bit complex. Here is a brief description from a US govt web site http://gps.faa.gov/programs/index.htm. ------------------------- BRIEF WAAS DESCRIPTION BEGINS ----------------------------- "How It Works Unlike traditional ground-based navigation aids, the WAAS covers nearly all of the National Airspace System (NAS). The WAAS provides augmentation information to GPS receivers to enhance the accuracy and reliability of position estimates. The signals from GPS satellites are received across the NAS at many widely-spaced Wide Area Reference Stations (WRS) sites. The WRS locations are precisely surveyed so that any errors in the received GPS signals can be detected. The GPS information collected by the WRS sites is forwarded to the WAAS Master Station (WMS) via a terrestrial communications network. At the WMS, the WAAS augmentation messages are generated. These messages contain information that allows GPS receivers to remove errors in the GPS signal, allowing for a significant increase in location accuracy and reliability. The augmentation messages are sent from the WMS to uplink stations to be transmitted to navigation payloads on Geostationary communications satellites. The navigation payloads broadcast the augmentation messages on a GPS-like signal. The GPS/WAAS receiver processes the WAAS augmentation message as part of estimating position. The GPS-like signal from the navigation transponder can also be used by the receiver as an additional source for calculation of the user's position. WAAS also provides indications to GPS/WAAS receivers of where the GPS system is unusable due to system errors or other effects. Further, the WAAS system was designed to the strictest of safety standards - users are notified within six seconds of any issuance of hazardously misleading information that would cause an error in the GPS position estimate." ------------------------------- BRIEF WAAS DESCRIPTION ENDS -------------------------------- One significant point that I want to make is that while WAAS is not considered a "ground based system" by the US Govt it still involves "ground facilities" and 91.205 (d) (2) reads "Two way radio communications system and navigational equipment appropriate to the ground facilities to be used". My position is that an ABEA (Amateur Built Experimental Aircraft) equipped with TSO C146a Gamma-3 certification WAAS avionics complies with 91.205 (d) (2).

I welcome information from across the ocean. You wrote: "This combined with addition of WAAS may make the difference of being able to certify for IFR operation in your experimental." One of my major points is that there is no such thing as "certifying for IFR operation" in an ABEA (Amateur Built Experimental Aircraft) here in the US. The FAA has neither the capability or, under the present FAR's, the process to certify an ABEA for IFR operations. Instead, for the equipment required for IFR operations, the builder / pilot is given the responsibility in the aircraft's Operating Limitations to comply with FAR 91.205, part of which requires: "Two way radio communications system and navigational equipment appropriate to the ground facilities to be used".

We have a RV10 with full Garmin stack and have had quite some difficulty getting pin outs and ended up sending the units to an avionics shop to get wired. (we purchased without looms) I have since spoken to the main Garmin agent in the UK and he explained that due to complexity of the avionics Garmin does not encourage(read does not make available pinout)homebuilders to do their own wiring. This can well be where the snag is in this story. You buy Garmin with a manufactored loom which is tested for proper function and there's a degree of assured quality. This combined with addition of WAAS may make the difference of being able to certify for IFR operation in your experimental. It may also be a good idea to print a copy of 91.205 to hand over to your DAR if he doesn't sign willingly! :-) Marcel ________________________________ Message 5 _____________________________________ Time: 06:50:37 AM PST US From: "Michael T.

Training is to learn something (hopefully as much as you can cause most GA pilots will never see training again). Real life is getting the job done. You could fly on an IFR clearance without any navigation equipment. For example if you filed IFR from say Phoenix AZ to Falcon Field AZ (15~20nm both under Phoenix class B) and the ceiling and visibility was 3000 and 3, you probably wouldn't need any of that fancy stuff or the old stuff for that matter. The flight would be a tower to tower radar vectors to a visual approach unless you wanted the non-precession instrument approach. All you would need would be a Com radio and transponder with encoder, that's it. You need the equipment needed to navigate, nothing more. So radar is usable to pilots and that is what you use on a GCA or PAR approach.

Is > that correct? > >Thank you, >Mike Yes. It's not uncommon for contactors to be referred to as "solenoids" and they do indeed contain a solenoid for operation. Starter solenoids mounted directly on starters have double duty - the solenoid extends the pinion gear to mechanically engage the starter. At the same time, it makes electrical connection between the battery and starter motor by means of contacts in the same assembly. Here, the proper term for the device is starter solenoid. As soon as you pull it off the starter it becomes a fat relay more properly called a contactor.

I used a Apollo SL 60 and King 155 VOR and GS to tke my instrument check ride. (No DME or ADF). The SL 60 is 129 certified for enroute and terminal. As long as the permanant data base depicts the required waypoints (NDB), the SL 60 is qualified to do the approaches and navigate to the missed approach waypoints. Then you can do ILS, VOR and Localizer approaches to meet the requirement. And incidentally, the new 400/500 WAAS simulator is at Garmin now. Neat - a glide slope signal is generated for the CDI as soon as you hit the FAF for GPS approaches. Incidentally, the instrument rating is highly effective at making you a better pilot - however it does not enable you to do approaches down to minimums. We have had an alarming bunch of crashes around the Carolinas for folks trying to do instrument approaches when the ceiling was 300' and visibility of a mile or less. Two Cirruses, two C182's and a twin Cessna made the unwise decision to fly ILS approaches to destinations where the weather was absolutely lousy. At least 14 souls lost in less than three months around here. Absolutely appalling!!!! ________________________________ Message 10 ____________________________________ Time: 08:13:47 AM PST US From: Subject: AeroElectric-List: 91.205 (WAAS) 1/5/2007 Hello Bill, Welcome to the world of IFR flight and thanks for your questions. You wrote: "....skip....can you explain how one might satisfy the training and checkride requirements in a WAAS-GPS-only equipped plane with no VHF nav?" No, I can't. But let's examine the reality of a WAAS-GPS-only equipped plane. I can't speak for the high end integrated systems (Chelton, Avidyne, etc.), but the Garmin 400 / 500 series GPS units that can be upgraded to a 430W or 530W configuration already contain VHF nav capability. I presume the newly built 430W and 530W boxes will also contain VHF nav capability. So one will continue to have VHF nav capability even after a WAAS upgrade or new purchase with these kinds of boxes. Maybe an issue is whether or not one should plan on / need a separate VHF nav box such as an SL-30 for back up purposes.** A) So with an approach qualified GPS (non WAAS capable) and VHF nav one can have four different instrument approaches to demonstrate to an examiner: 1) VOR, 2) Localizer, 3) ILS, 4) GPS. B) With an approach qualified GPS (with WAAS capability) and VHF nav one can have five different instrument approaches to demonstrate to an examiner: 1) VOR, 2) Localizer, 3) ILS, 4) GPS, 5) an approach that requires WAAS to achieve the published minimums. C) With no approach qualified GPS and only VHF nav one can have three different instrument approaches to demonstrate to an examiner: 1) VOR, 2) Localizer, 3) ILS. And the question of ADF capability in your aircraft doesn't need to raise its ugly head unless you choose to use some GPS capability to substitute for a NDB where permitted. You might want to discuss the above positions with your examiner prior to showing up for the practical test to determine if he agrees. OC -- The best investment we will ever make is in gathering knowledge. **PS: I use my GNS 430 and SL-30 together whenever possible. If one intends to fly IFR to the extent that an approach capable GPS is needed then I think the investment in a separate VHF nav box is well justified.

Without getting sidetracked into a discussion of how to avoid unpopular NDB navigation, can you explain how one might satisfy the training and checkride requirements in a WAAS-GPS-only equipped plane with no VHF nav? You didn't say this was the case, but the question has relevance to me as a homebuilder still planning his IFR panel upgrade. Thanks, gentlemen.

The thread started out being about whether WAAS GPS met the letter of the law for "ground-based facilities to be used," and I asked a question expanding the scope from operational IFR to include the training environment, which is where I'm soon to be. I've concluded that, even though our current ground-based VHF technology is antiquated, it is essential for adequate IFR instrumentation in today's cockpit, and will be in continued use for decades more, if only because the system is standardized worldwide and there are a lot of nations without the funding to replace VHF 1940's tech with anything better for the air carriers to use. It might be somehow legal to fly IFR in IMC with only a WAAS GPS for nav and approach, but I don't think for a minute I'd ever get an istructor or examiner willing to train and sign me off that way, so it's back to plan A for me, which means there will be an SL-30 in the panel besides the GPS gear. Redundancy is a good thing. -Bill B. On 1/5/07, Mike wrote: > > Don't confuse training and real life.

Many VOR, ILS, Localizer and even NDB approaches require the use of an ADF or DME for them to be executed. Sometimes that information will be in the title such as "VOR DME to Rwy 31" Other times it will just be a note somewhere on the page that says "DME required" or "ADF required". To shoot those approaches you must be so equipped UNLESS you have an IFR approved GPS. It does NOT have to be an approach approved set. One that is only approved for Enroute and Terminal guidance is sufficient. The GPS may be used in Lieu of ADF and/or DME for almost all purposes anywhere in the United States National Airspace System. One big No/No. You cannot use the GPS to execute an NDB approach unless it is equipped with an overlay approach. In that case, it will say "ADF (or GPS) to Rwy 31". A further restriction is that the GPS being used must have a current data card installed and it must be used to obtain the data. Any other time when the words ADF or DME are included in the approach name or where there is a note stating that an ADF or a DME is required, the GPS may be used for whatever purpose would have required an ADF or DME. Unfortunately, that provision is not well known. You can check it out in the AIM section 1-1-19. paragraph f.,1 (a) through (d), and g.

I'm aware of no combination in the physics that suggests a battery can damage a regulator. Most likely, it's the other way around. The symptoms you describe mimic a shorted regulator the causes the alternator to run flat-out. The only reason the bus voltage is not climbing quickly to 100 volts or more is that your new battery is doing its level best to use up the alternator's output. Fortunately, the alternator is current limited and the new battery fairly robust . . . but the alternator will eventually win. The regulator is not difficult to replace but you need to know the make and model of your alternator to acquire the right replacement part.

Is GRT going to TSO this equipment? They haven't gone that route in the past. Note that paragraph 1-1-20 c of the aim requires that WAAS avionics meet either TSO C145 or 146A. Your SL-30 would make it legal to fly IFR, but if your GRT WAAS / internal GPS in your EFIS is not TSO'd it is not clear to me what additional legal value it would have when operating IFR. Like any other reasonably capable GPS unit it could provide very beneficial situational awareness support.

The simple explanation is that an IFR approved GPS CAN be used for all of those functions under the provisions of "GPS in Lieu of DME and ADF". Why did they not allow it to be used to execute an NDB approach? Because their policy was that all waypoints had to be auto-sequenced for any approach flown by GPS. The operator would have been required to either load a way point or think a little bit about what they were doing. When we were fighting to get the "In Lieu Of" provisions approved, every FAA person I talked to agreed that doing as you suggest would be better than what we now have for an NDB approach, but it didn't fit FAA policy. We got what we could, but not everything we wanted. If you have any more questions concerning the application of the current policy, please ask. The key thing is that: For flight in the USNAS we don't need a DME or an ADF as long as we have an IFR approved GPS with at least enroute and terminal capability. The language in 1-1-19 gets a little convoluted because so many different departments of the FAA had to sign off on the final interpretation. Each one wanted to add their own two bits worth. It took us three years to get it through in even that very rough form.

If you can frame an individual question, I would be happy to attempt an individual answer that may make it a bit more clear. Incidentally, during the time we were working on the approval, I did ask for the right to use the GPS to shoot NDB approaches. One of the things I was told was that it really wouldn't make any difference because all NDB approaches would either have an overlay or a standalone GPS to the same runway with the same or lower minima. Unfortunately the FAA policy has changed since then and they will no longer approve a new overlay. There have been a few new NDB approaches placed in service with no overlay and with no alternative GPS approach. I don't like it either, but that is the way it happened. One thing that I have found out is that there are very few folks who care. Consequently, we have very little chance of getting anything changed. If I delve back into my wandering mind a bit, I imagine I could come up with a half dozen or more things we asked for and didn't get because not enough people took the time to back our efforts. Such is life. The squeaky wheel gets the grease and all that jazz!

I appreciate your willingness to share but not sure if it would help me understand since seemingly there is no logical understanding.

Yeah, the itty-bitty hand-helds are victims of way too much marketing hype. I've used them vehicle to vehicle solid out to 1/2 mile and open line-of-sight to about a mile. One pair I had was good to a couple hundred yards vehicle to vehicle. However, for the tasks to which I've applied these radios a range of a few feet has been sufficient. ________________________________ Message 34 ____________________________________ Time: 08:52:40 PM PST US From: "6440 Auto Parts" Subject: Re: AeroElectric-List: Keyed push to start switch source? Probably a good move, at least on the switch, I have had tractor, forklift, backhoe etc starter switches go bad that had lasted for Who knows how many years in rough outdoors environment. And like a doofis I go down to the local auto parts house and replace it with cheap auto switch which does'nt last but maybe a year, done it several times. I keep a cheap spare in my desk drawer. Maybe next time one goes bad I'll remember that you get what you pay for and get an original equipment replacement. Hopefully they still make em as good as they used to. One thing about it a starter switch going bad is definately not going to spoil your day it's just so easy to jumper around them.
