    Subject: Re: IFR GPS
    Thanks to everyone that replied for their answers. I'm aware of the differences between Certificated and Experimentals, and was hoping for some factual insight. I had not thought of being ramp checked as a possibility since (in my experience) the FAA only was concerned about paperwork, and not the way the airplane was equipped. Polling the FSDOs (again, in my experience) is a waste of time since they'll only direct you to the FARs and nobody is going to put their butt in a sling by giving a written opinion. ..... And David's post pointed out that the regs are totally outdated. My partner in the -10 flies professionally, and I'd hate to have him faced with the FAA firing squad. All the research I've done so far points to the fact that in order to be used as a primary IFR GPS in an experimental aircraft the GPS must MEET the requirements of the TSO. I'm a retired electronics engineer, and used to reading specs. However, it seems (at least to me) that even trying to see if your GPS meets the TSO is next to impossible. Degree in GPS certification is almost certainly required ..... and I don't have that. The problem really lies in trying to get the information on the GPS that's in your hand (or mounted in the panel). The manufacturer of the glass panel GPS I'm looking at did say that their GPS meets SOME of the TSO requirements, but not all. :-( Didn't say what parameters are on which side. EAA was really responsive to my query (I'm sure they get a lot of the same questions over and over again) which I didn't expect. So far, I nobody has stepped up to the plate and said 'I fly behind (insert favorite glass panel) with built-in GPS, and this is what I do. Even off list. I'm sure I'm not the only one in this situation. Linn do not archive Paul Besing wrote: > Great post, David. GPS is great, but we've been fine without it for a > long time.

    Care to share what key features attracted you to the Odyssey over the other glass panels? I expect I will also select a stand alone IFR GPS, that hopefully will provide data to a glass panel. Don't want to have more $$ in panel than in airframe. linn Walters wrote: > That does seem to be the bottom line.

Don't want to have more $$ in panel > than in airframe. Cost, capability, ease of software upgrade, ease of installation, just to name a few. They don't do TSOs .... only experimental to keep the cost down. Did I mention it's huge??? Here's a screen that you don't have to squint at!!! You can customize the screens at home with their software, or if you know that you want something different, they'll do it for you when you order. They have radios controlled from the panel that can be black box or panel mount. They have an IO module that collects all the engine data and sends it on two wires through the firewall to the unit. Autopilot servos coming out soon. Check it out at http://www.mglavionics.com/html/odyssey.html ( Stratomaster, US distributor) or go to the company site at http://www.mglavionics.co.za/. Different info. Far too many +s to list here. I figure around $6000 for the panel and sensors ..... doesn't include the radios or the servos (around $500 each). If you're going to OSH, they're in hangar B space 2139 and 2140. They were at Sun-N-Fun in the ACS booth. If Matt's there, tell him I sent ya!!! :-) Linn do not archive > linn Walters wrote: >> That does seem to be the bottom line.

    Subject: IFR GPS
    Paul, Not at my desk today so I don't have the FAA's TSO approved list webs ite at my fingertips, but you can search it on the fAA.gov webpage. TSO-129 is the GPS IFR certification. TSO-146 is the GPS/WAAS certification for stand alone NAV radios; i.e. King KSN 770, or Garmin 430W TSO-145 is the GPS/WAAS certification for FMS with WAAS sensors; i.e. Avidy ne Entregra 900W or Garmin 900 or 1000. Not all certifications have approach capability; it depends what the manufa cturor has requested. You're correct; FSDO's have little knowledge; but then again, that gives me a job in trying to educate them.

    Say Folks, I'm in the process of attempting to purchase a "was Flying" project t o use while I continue building my(was 6A) RV-6, but I'm finding out that t he RV's and others are on an "Acceptable" list but not others like Tailwind s and Hiperbipes, etc. Are there companies/organizations that some of you a re aware of that will finance Ex-Planes other than the popular ones? I wou ld rather use "Other Peoples Money" for the interum aircraft and not have to empty the RV Piggy Bank. Any referals/suggestions? Thanks.
