I agree with Ferg that the position and anticollision lights are for the protection of others, so we should insist that other builders design for safety all around. Don't be shy. Not just your own life is at risk. I have made offers to test LED position lights made by other but got no takers. I state categorically that many LED lighting systems are not per the FAA specs. See my website for information. I have sold some position lights that ARE per the FAA specs. One of my customers landed using only the LED position lights to see the runway. An amazing accomplishment. But the LEDs were really really bright. I am planning to reintroduce these later, but others will enter the field with good systems too. For now I am working on too many other things. Exceeding the FAA specs would be in the best interest of builders who may want LEDs but don't want to certificate them or buy certificated parts. It is also true that the differences in LEDs (soon 4-10X the luminous efficacy, essentially infinite lifetime, organic LED sheets, etc.) gives rise to vastly different schemes for placement and operation of exterior lighting. I am interested in making a flush beacon. Ideas appreciated. As for James Foerster's testing: It will be great to see your results. We anxiously await data.

You wrote: "In that case, the lights are not just for our protection but for the Others out there. That's what I think the U.S. regs require - service to other flyers." You are right on target. Whenever we fly we are sharing the airspace and, if so equipped, the electromagnetic environment with other aircraft and the air traffic control system. Our own amateur built experimental aircraft, to varying degrees, must be compatible with the other entities to avoid creating confusion or unsafe conditions. Here is an extract from the introduction to my table MINIMUM INSTRUMENT AND EQUIPMENT REQUIREMENTS FOR POWERED AMATEUR BUILT EXPERIMENTAL AIRCRAFT "The builder should note that some items required by the FAR's are described in the FAR's as needing to be approved, but since there are no certification standards established for amateur built experimental aircraft no formal individual item approval, such as meeting a TSO (Technical Standard Order) or FAR Part 23, is required. However certain items must interface properly with ATC (Air Traffic Control), other aircraft, or other entities external to the aircraft. Transponders, communication radios, exterior lighting and ELT's (Emergency Locator Transmitters) are examples of such equipment. Therefore, the builder could expect that the initial airworthiness inspector of his aircraft may require evidence that this type of equipment in the aircraft is acceptable to the FAA. But regardless of the actions of the inspector, the burden for complying with the provisions of the aircraft's special airworthiness certificate (which includes the Operating Limitations), and the relevant FAR's, rests with the builder / pilot."

The coloured lights are there so that (like ships) an early estimate of direction of travel be made in order to plan evasive manoeuvres if needed. In that case, the lights are not just for our protection but for the Others out there. That's what I think the U.S. regs require - service to other flyers. If they don't satisfy the particular standards drawn up, they don't protect other aircraft - and that could be 300 people..... That's why I've chosen an approved source for lights.

My basis was misremembering your original explaination-sorry. Thanks for setting the record straight once again. That said, I am trying to measure the available commercial units to see how close they come. Since that post, my sources tell me that the inspectors for exerimental and amateur built aircraft are taking a closer, and more jaundiced, look at the LED position lights. I did see some units molded into the wing at the last Oshkosh that clearly did not meet the field of view requirements, although brightness is impossible to judge in the daylight.

Blue ones, red ones, yellow ones.you name it. One wire to three wires.you name it. .and some bigger crimps using the B&C #10 to #2 wire masher that they have. It works great and has been an enormous help. I have learned, and I am passing it to you, that you do a grab and yank test on EACH wire in each joint. If you grab all the wires it once, it only proves that one is in there for keeps. Think about that. Also I have learned that the blue fastons are a little more loose on the faston ground or fuse tabs than are the red ones. Be careful if you make your own "forest of ground tabs" that the rows are not so close together or so out of the way that you can't see if each and every connector is fully seated. In my humble opinion (IMHO) any faston going into an electronic ignition component, or any fuel pumps, be given the utmost of care and attention. Give equal attention to power, to ground, to any splices..every dam connector in the chain. Equal attention to data transfer issues.like the map signal on your Elect Ign. Treat it like torquing the nuts and bolts on your throttle cable, because it has the same affect.

Measure the voltages at the source and any accessible points along the way to the E-Buss. If you used the Bridge Rectifier with Fastons this may be 4 points. Take these measurements while the buss is loaded (your SL30 PTT experience suggests series resistance) you will see a drop of about 1.2 volts (unless you used a Schottky diode* *then it will be less)* *across the diode, more than that between any two points will isolate the poor connection. You may also try pulling hard on each of the fastons. If you can pull them off with moderate force they are not crimped properly. Diodes are typically not intermittent, they generally open or short and usually only when abused (over temp or mechanical stress) Bad crimps are common, good crimp tools, properly sized (wire and terminal) and high quality connectors (AMP PIDG or Molex Avikrimp) with metal insulation support sleeves and careful installation will resolve this. Other things to look for are partially cut wires (rare if properly installed), corrosion on terminals, fuse blocks, fuses. It may be helpful to load the E-Buss with a high current device (landing lights, pitot heat, both?) in my installation this only requires moving a connection a few inches on a split fuse block. That will obviate the need to key the transmitter to get the current up and thus the IR drop. (The voltage drop is equal to the Current I * R Resistance plus any diode junction drops that are in series) Good luck. -- Ralph C.

It may be of interest to EAA'rs disappointed with the current state of the organization. ============================ Following the lead of a fellow member of the Dyke Delta Yahoo group, Bernie, I sent the editors at EAA an email explaining why I was not renewing my membership. It looks like Bernie and I either spoke to soon, or our actions are finally having the intended effect. I'll not argue the point either way, but I got some news through the grapevine this weekend that is very encouraging concerning the EAA. The editor of Sport Aviation has been fired. Now, I hate to see anyone lose their job, but here is how I understand the situation. The guy took a job editing what should be an intensely hardcore aviation publication, and he didn't have so much as a PP-SEL. It appears that he had no interest in flying airplanes, and even less in building one. He was in the wrong place. That's sad; both for him and the EAA membership. Over the past year, EAA membership dropped 20%. Sport Aviation content was cited most often as the reason. That is sad; both for him and the membership. He is being replaced. I wish him luck in finding a position better suited for him, but the bigger issue for EAA members (past and present) is why he was replaced. The board of directors saw the 20% drop in membership and started asking why. Have you seen the makeup of the board? Sport Aviation printed the nominees for the next year a couple months back. There weren't but a couple that had ever worked on an airplane, and I believe only one nominee that had ever built anything. The rest were bean counters and management types, with a couple academics thrown in. While bean counters and management types are both necessary and useful, I think it wouldn't be that hard to find a few that had built at least one airplane and would know what is wrong with the EAA's focus. Instead, they, being bean counters and management types, do what bean counters and management types do. They look at spreadsheets and charts and try to draw a picture of reality from the summarization. Spreadsheets and charts leave out a lot of data and twist reality all to easily. Until the membership started dropping, they assumed everything was hunky-dory, and all the talk about losing focus was just background noise. Now the moaning has risen to a roar. Members are leaving. So, we've punched them in the nose to get their attention. It is time for a come to Jesus meeting where we calmly and clearly explain what the problem is. If you've left the EAA without an explanation, please send a quick email to editorial@eaa.org and state why you left. Just a few polite lines so that they will know. If you're considering not renewing your membership, let them know that. If you've tried to make your voice heard before, but feel you were rebuked, please try again. I believe the microphone is turned your way now. If you know someone who is trying to fix the EAA from the inside, please mention their efforts so that the board will have insiders to turn to for advise. It's not often that an organization as large as the EAA will see one in five members drop out in a single year. This is an historic opportunity to set thing straight. The people in charge will be paying attention like never before. It may be that the editor will just be a scapegoat, and it will be back to business as usual in a few months. I think it more likely that the board is genuinely concerned, but they just don't understand. If we speak up and the situation is the former, then we can say, "We told you so" next year when the membership drops another 20%. If the situation is the latter then speaking up now will help draw back the 20% that left and insure that they stay. It is my opinion that the problem with the EAA is that the leadership has forgotten why we are building airplanes. It is NOT, by any means, simply to have an airplane. The analysis has been done all over the place, and everyone agrees it would be more economical and less labor intensive to get a second job, buy an airplane now, and be in the air immediately. *WE* as builders know that. We're not stupid...DANG-IT! The reason we build airplanes is....get this....PRIDE! Plane (har-har) and simple. We want to say, "I built that." We want to compare our workmanship to the guy on the next row, and marvel at the simplicity/uniqueness/complexity/workmanship of the guy on the next. The more bolt-on, manufactured goods are added, the less pride is involved. The more the leadership has forgotten that PRIDE is the driving force and been lured astray by advertising dollars from manufactured goods, the more they've eaten away at the heart of the organization. Now, I've got nothing against manufactured goods, or their advertising. There are some parts of my project that I just had no interest in making, wheel hubs, for example, so I chose to buy those off the shelf. The problem is that I often get the feeling from the EAA organization that my project is lessened by it not being a kit, or by me making my own strobes or marker lights. If I'm building out of pride, and you look down your nose at me for building...well, that's just a punch in the gut, and I don't really care to be around you. You can't go around punching your members and expect them to keep coming back.

I looked at the published, audited financial statement for EAA. It compares the most recent audited years ending February 28, 2006 and 2007. While the report does not give the number of members, it does show the revenue from membership dues (same rate for both years @ $40). There was a $143,667 increase in revenue in 2007 over 2006. Based on that, it seems membership increased. For membership to have dropped by 20% in the last year, the membership dues revenue would have to show a decrease of more than $1.2 million. As for Mr. David Hipschman, he is still listed as the Editor of Sport Aviation magazine in the August issue. Even if he is leaving, there is no way to know if he was fired. I also looked up David Hipschman in the FAA database - he is a PP-ASEL for three years now and lives in WI. It may still be a good idea to suggest that members write EAA with their own ideas for change or improvement of the organization, but I'm not sure that we can take the so-called "change" as a given - or the validity of this email for that matter.
