Starting to drift off topic (so I modified it) but I would encourage everyone to operate a transponder at all times even if you never talk to ATC or are always in remote areas. With $450. PCAS type anti collision units available it has to be safer to operate a transponder. Even in an airport traffic circuit I find the pcas sometimes has me straining to locate traffic when I haven't heard any radio calls but I know there is a transponder nearby. Anybody never had the wrong frequency tuned or forgot to make a transmission? If something like a pcas confirms that a transponder is reporting the same altitude as the altimeter, it has to be safer to have a transponder turned on. There is a risk that both encoder and altimeter are reporting the same erroneous altitude so certification does have safety value as well as legal value. Many of us fly enough formation or could do the manometer test to rule out that risk though. Much of the time and dollars spent chasing static system leaks is irrelevant in real world operation for non pressurized aircraft. A leak that makes the test impossible is usually insignificant in normal ops with an unpressurized aircraft. Small leak - hook test equipment directly to encoder and let the owner deal with the leak later. I suspect that the overall air traffic system safety risk from operating a transponder that is reporting accurate altitude but may fail other certification parameters is essentially nil. Anybody know different?? Would relaxed certification requirements reduce safety or would it make transponder ownership more affordable and actually increase safety? It is not the cost of a transponder (or 406 ELT) that keeps some of us from upgrading. It is the continuing cost of ownership (certification costs) that adds little value to us or other airspace users.

Similarly only the term MANUFACTURER rather than BUILDER appears in many other generic FAA forms that are used in the process of getting our experimental amateur built aircraft through the FAA administrative wickets of purchasing, registration, and certification. To wit: Form 8050-2, AIRCRAFT BILL OF SALE Form 8050-3, CERTIFICATE OF AIRCRAFT REGISTRATION Form 8050-88, IDENTIFICATION NUMBER ASSIGNMENT AND REGISTRATION OF AMATEUR-BUILT AIRCRAFT. (This form refers to the "bill of sale from manufacturer of the kit" -- they mean the company that created the kit from which the aircraft is built.)** Form 8050-110, CONFIRMATION OF RESERVATION OF UNITED STATES REGISTRATION NUMBER. The use of these generic FAA forms in the process and the use of the term MANUFACTURER in those generic forms and on the FAA web site does not make the builder of an amateur built experimental aircraft into an approved aircraft manufacturer in the eyes of the FAA. This fact is made abundantly clear in the FAA Form 8130-7 SPECIAL AIRWORTHINESS CERTIFICATE for each individual experimental amateur built aircraft when the MANUFACTURER block is filled with N/A (Not Applicable) and the BUILDER block is filled with the builder's name by the FAA Representative who fills out and signs the form. 'OC' Says: "The best investment we can make is the effort to gather and understand knowledge." **PS: Note that this same form number 8050-88 is use for a different FAA form AFFIDAVIT OF OWNERSHIP FOR AMATEUR-BUILT AIRCRAFT which does use the term "Builder's Name". I guess the FAA was running short of money and could not afford different numbers for these two different forms. ================================================== Time: 09:23:27 AM PST US Subject: Re: Avionics-List: Encoder Certification From: lessdragprod@aol.com Hi All, I just checked the FAA records: William E. Boyd, Jr is the "manufacturer" of a RV-6A. There is no BUILDER block on the aircraft registration form. What did you put on the 8050-1 form you sent to FAA Oklahoma City to register your air craft? I think this is the first form the FAA sees for a new homebuilt.

This time we will restrict the discussion to just charting of uncontrolled airspace and leave transponders out of it since that subject seems to make some peoples' head hurt. 2) ".............. one has to actually look at a sectional (NOT IFRchart) to see where true "uncontrolled airspace" exists." and "RE: #2. Look at the Class E section of this page: http://www.flytandem.com/airspace.htm" {Response} Just looking at a Sectional chart alone and the web site diagram does not permit one to see where all true uncontrolled airspace exists. Here is why: A) The AIRPORT TRAFFIC AND AIRSPACE Legend portion of current Sectional charts has this wording in it: "Only the controlled and reserved airspace effective below 18,000 ft. MSL are shown on this chart." This means that the location of lateral areas of uncontrolled Class G airspace that go from the surface up to 14,500 feet can not be determined by looking at a Sectional chart. B) The AIR TRAFFIC SERVICES AND AIRSPACE INFORMATION on a current IFR ENROUTE LOW ALTITUDE chart has these wordings in it under AIRSPACE INFORMATION: "Open area (white) indicates controlled airspace (Class E); unless otherwise indicated." "All airspace 14,500' and above is controlled (Class E)" "Shaded area (brown) indicates uncontrolled airspace below 14,500' (Class G)" So one needs both Sectional and IFR ENROUTE LOW ALTITUDE charts to completely determine where all uncontrolled Class G airspace is located. The Sectional chart will tell one where the controlled Class E airspace exists both laterally by an outline and vertically by either magenta or blue shading, but won't tell one where the the lateral dimensions of uncontrolled Class G airspace are. The IFR ENROUTE LOW ALTITUDE chart, by brown shading, will show one where uncontrolled Class G airspace exists laterally from the surface up to 14,500. Why don't you get an IFR ENROUTE LOW ALTITUDE chart for some areas out west where there is some brown shading, check it out, and let us know what you find. Our IFR ENROUTE LOW ALTITUDE charts back east are all white between the navigation information. Thanks.

Understand. Then the BAT terminal on your starter becomes the forward power distribution point. Your alternator b-lead would tie in there too. Consider an ANL current limiter for the alternator B-lead where the BAT end of the limiter base could become the distribution point. This would prevent piling all those wires on one terminal out on the engine.

The "cranking amps" ratings of batteries are generally not high on the priority of items in system design goals. Weight, size, ease of installation, cost of ownership, and other features usually set decision process in OBAM aircraft. Cranking amps for an engine is pretty whispy too . . . it depends on tightness of the engine, temperature, viscosity of oil, motor efficiency, gear ratios, wire sizes, etc. In other words, I'll suggest you start with a 3 x 6 x 6" SVLA, 17-20 a.h. battery with expansion room for upsizing later. See how that fits with YOUR notions of satisfactory performance. A new battery that size will get your engine going with about any of the modern starters. The question that drives an up-sizing decision is how often you need to replace the battery for the environment and missions you fly. MOST builders are happy with that size battery.

Not a big deal. There are tens of thousands of airplanes flying with nylon over PVC wire in them . . . a few thousand more with cotton over rubber . . . they're not falling out of the air trailing smoke nor gassing their occupants with the byproducts of inflight fires. The short pieces of PVC on the ends of the fuse holders represents no significant risk. I'd go with the fuses.

I like Z13 for it's simplicity of operation, and Z14 for it's indepandant power supply. I submitted a wiring diagram that you stated you were "praying over" a while back. Seems like I have fallen into an area similar to John so I thought I would probe you again. In your last post regarding my inquiry you said to use Z9 which seemed to address other issues. I figured you were just busy with moving so I didn't pursue the issue at the time. Since John has asked a very similar question, perhaps you could give us your opinion of using Z14 for battery bus, starter and alternator, and then a main-bus and e-bus from there as with Z13. I like this appriach because the inflight troubleshooting is eliminated. Using a low voltage checklist you can get to stable operation in a few seconds after a low voltage envent is detected on either battery bus.

IBBS is a complete back-up battery solution for powering critical electronics such as EFIS, GPS, Autopilots and Engine monitors. The IBBS product combines a rechargeable ni-mh battery, a smart charger circuit and the transfer switch in a single enclosure that is easy to install and only 1/2 the weight of a comparable lead acid battery. The IBBS provides about 1 hour of back-up endurance for typical EFIS and GPS systems; additionally, it includes surge suppression and allows systems to operational before and during engine cranking. The IBBS system is very easy to install and eliminates other field installed components such as transfer contactors and diodes. The IBBS product has been tested by Garmin for use with their G3x series of products.

Per your suggestion of using smaller batteries to make a lightweight Z14, I looked at the Odyssey PC 310. With two of them I'd have 620 amps for 5 seconds (wondering how many engine start trys I get). According to the website that I linked in my original post, I need 427amps to spin my 6cyl 350 in. engine. The PC310 (6lbs) is an 8AH battery with a 25 amp discharge capability of 9 minutes. Two of them gets me about 1/2 hr @ 12 amps, which is what my 2 no frills battery buses and E bus need. Having 2 alternators makes me OK with this minimum size battery bank and this light weight Z14 weighs less than the Z19 with 2 17AH batts by about 10 lbs.
