A simple circuit contains a source(battery, alternator), = load device (motor,light,etc) and a conductor (wire). To that you can = add a control device (switch) and circuit protection (fuse, circuit = breaker). There are two formulas that I required all students to learn, = and they used the following terms and symbols: E (electromotive force = measured in volts); I ( current measured in amperes); R ( resistance = measured in ohms); and finally P (power measured in watts). The = formulas are EIR where E =3D I times R and PIE where P =3D I times E. = With these two formulas you can compute all that you need to know about = your circuits. In addition to this information you must know that with = direct current voltage the size of the wire must be increased as the = wire gets longer, because the resistance in wire increases with length. = Anyway there is a chart to help you select the correct size. To = correctly select a fuse or circuit breakers you must consider the = amperage in the circuit. Your computation must include the power = consumed by the load device (motor) for example a 12 watt motor in a 12 = volt system uses 1 amp. A 100 watt landing light in a 13.5 volt system = pulls a current of 7.4 amps and could use a 7.5 amp fuse or CB if you = don't consider wire length. Once you know the circuit amperage you can = go to the chart and pick a wire which can carry the current over the = distance intended. In a fuse it is the heat in a circuit that caused = the fuse to melt and in a CB it is a magnetic field that causes it to = open. conductor (wire) size is picked to carry the current to the load = with out overheating. you pick the smallest wire to get the job done so = as not to add too much weight. This is a big subject and it is not my intent to do an online lecture or = bore anyone.

First , with the handlebars straight ahead, he gave the tricycle a hefty push and the tricycle tracked pretty straight down the sidewalk at a good pace. Then he simulated a taildragger CG configuration by reversing the front wheel of the tricycle by turning the handlebars 180 degrees. He then gave it another shove and after just a few feet, the tricycle violently swerved to one side and tipped over. Looked just like a groundlooping, high-wing taildragger. Interesting.

You want happy feet, light and loose, all the way through takeoff and landing. Unfortunately, too many pilots just sit there, like a bump on a log, with their feet firmly braced against the rudder pedals, just waiting for the airplane to do something, so they can respond. Lets talk landings, what are you looking for in a taildragger, a three pointer! That's right, you want all three wheels to touch the ground at the same "coordinated" time, with minimum speed. This means, once committed to the landing roll, you've got to keep backpressure on the controls, which will provide the positive control needed for an effective rudder, while your happy feet keep the plane center of the runway. Note: Two things are required to land an airplane effectively, precise speed management & timing the flare. Ref: The Complete Taildragger Pilot, by Harvey S.

Your fuse is there to break the circuit if there is a short in the circuit that would pull fire-starting current otherwise, you don't want it so close to the load amperage that it cuts off your landing lights because of a transient voltage spike. Fuse this light with a 10 A or 15 A fuse, size the wire accordingly. I'm still not sure what I think of Mark Langford's two-systems no-fuses approach. Never heard that one before -- is that in the AeroConnections book? I'll have to get that and read it, I'm always willing to learn. I like fuses, they can isolate a faulty circuit so the rest of the system keeps working. With no fuses, a fault in any load on any circuit can draw it all and shut everything down while it is trying to make stinky smoke. I guess if you have a complete second system to switch to, OK, but if you develop a short in one instrument, wouldn't you rather have one fuse pop, one instrument go dead while the rest keep on, than shut it all down? Seems to me that shorting instrument could shut your second system down as well as your first. Just trying not to test the trapped-smoke theory . . . Rich H.

(I picked this up from some HP Technicans years ago at the HP inkjet division). Every electronic component that functions works on a precise amount of "trapped-smoke". This trapped smoke is what keeps your Pentium, and Monitor on your computer working. Or in a car, keeps your radio and alternator working. If somthing happens to cause the device to release the trapped smoke, it is known as "letting all the smoke out". Once you have let all the smoke out of a device, it will no longer function. In some cases you can release a small amount of smoke, and a device will still operate. I have tested this theory with many modern IC's and even some wire, and like most working theories, have yet to disprove it. I work testing IC's for a living, and once every year or so, will do somthing stupid to release trapped smoke from some fancy IC prototype, which will in turn make me real popular with some companies engineering department, which had loaned me the super dooper new prototype to evaluate/test. There seems to be some relationship to how important and expensive the IC's are. For example, it seems to be easier to let the smoke out of a chip that goes into a $500 graphics card, than it is to get the smoke to leave a $10 chip. -- Ross > Just trying not to test the trapped-smoke theory . . . > > > Rich H.

Off the top of my head I'm thinking 18 gauge wire. One black (GND) and one white... or you can use unshielded wire braid for the GND line and red wire for the +12V. The one downside of the wire you buy at AutoZone/HomeDepot, and Radio Shack... it uses cheap plastic insulation covering... which has a LOW melting point. If you have a short... it melts.. and zap. The cool wire is teflon coated wire. It's harder to find in color, but the mil-spec aircraft wire sold by Aircraft spruce is white, and is teflon coated. The nice thing I like about it, is that if you solder any connections, the insulation doesn't melt, like the cheap autozone wire. Belden makes teflon coated wire in rainbow colors, but it's hard to find, you need to find an electronics distributor who can sell some spools. I tried to go that route, so I could color code my instrument panel wiring, but gave up and just bought the white stuff. I did however run the AutoZone quality wire in my wings for the wingtip NAV lights, it's currently unused however. I had an electrical short years ago on my Honeymoon in my '78MGB, and when I got home the entire thing melted and caught fire... so I'm not a fan of cheap wire. (Teflon wire would have melted, but would have been less of a mess).

The flying club Mooney turbo 231 6 cylinder got them at a cost of 1K per injector ($6000). And you could cruise at 170Kts at altitude at around 9gph after leaning. Isssssh - Someone's having you on here, that must have been the budget for the whole fleet. Have a peek on the GAMI site (http://www.gami.com/) TCM /Lyc 6 cyl = $800/set on exchange ($950 turboGami's) Lyc 4 Cyl = $700/set on exchange. I suspect your club Mooney may have received the whole deal - $6k would cover the Gami's and a very nice graphic engine analyzer with parameter settings and alarms on EGT and CHT (all 6); oil temp /press /fuel flow (HP readout) fuel tracking /OAT and obviously - the whole ROP /LOP mixture tracking /processing and indication. It is however not about the 15% plus fuel saving (not that this will hurt)- it is all about taking the motor to TBO without hassles or even a top o/haul. More so, this is about reliability during daily operations. I know of a pair of TIO 470's that went 200 hrs over TBO without any problems, including turbo's or a top. Only hassles I recall related to the exhausts - this was related to the Gami's. My motor (IO-540 K1A5 - 300hp) was a typical midlife Lyc when I bought the bird - I know, I had a look with a boroscope (sp). Fair accumulation of carbon and BB's at and below 65. 300 hrs later it was almost clean inside and all the BB's were over 70. That got my attention. 400 hrs later the motor failed due to a failure in the accessory drive train and the bird was written off. (Nobody hurt) I got to see inside the cylinders - clean as a new engine, very little C, certainly a great deal less than 400 hrs earlier. No burnt vales as the OWT's promised. Clean burning means no un-burnt whatever - keeps the cylinders clear, valves (stems and seats) clear and efficient, cooling works better, plugs last my plugs were still fine after 400 hrs). The next bonus was range - my Cherokee 6 carried 84 gals and sipped away at 10 gph at (typically) 12,500' (my favourite level over Africa) and still cracking 135KTAS - you figure the range with only one take off, it is agonizing (but very handy) The short story is that someone has painstakingly figured out a set of different size nozzles for each of the engine models that they cater for. This is antiquated and crude by modern (auto) standards, but it does mean that we can address the differences in gas flow patterns that cause different amounts of fuel to be delivered to the various cylinders in the traditional old airplane engine. That is why, when you lean an aircraft engine (slowly), it will initially run rough as a first indication. It runs rough simply because each cylinder is receiving a different amount of power (it is getting more /less fuel than its neighbour). A set of GAMI's will iron this out (mostly) - Gami will re-issue you with more accurate nozzles if you have an engine monitor and provide them with specific info on your engine. All of the above is obviously irrelevant to most modern auto engines, their systems are decades ahead and probably have real-time info from each pot telling a processor to change the mixture for almost each stroke.

Message-ID: Content-Type: text/plain; format=flowed MIME-Version: 1.0 Precedence: list Message: 21 Any of the KR gang coming to i39 for the flyin on Saturday? If so, please reply off line. I sure would like to see some of the KR gang show up but so far I haven't heard from a single one. If there is no interest, I'll not post in the future as this will surely become an annual event. I currently have about $1800.00 of door prizes with a UV/rain canopy cover being the lastest to be added to the list. It has shaped up to be a rather large flyin, I seriously doubt there is enough room on the newly expanded ramp to park all the airplanes. I'm not even going into how many airplanes I expect, suffice to say I am meeting with the FBO today about issuing a NOTAM concerning heavy traffic on Saturday. If you want a peek at what is available out there, Dynon, AnyWhere Map, Grand Rapids EIS, EZ Pilot Autopilot (yes, very affordable and would fit a KR), TruTrack, AeroElectric, Brian's post lighting, wiring, tools, the list goes on, this is a nice chance to get a little up tight and hands on. Even if you don't I have three formation groups committed to attend, one a group who performs at SNF and Oshkosh, one how has challenged them to flyoff and one group made up of current F-16 fighter pilots. You've seen my posts and I know it's not Friday but if you want to unglue your epoxied fingers and drop by, I'm sure you will have some fun. Cell 859 625-2844 Let the party begin!!!

I think this included installation and an engine analyzer... but the club sold that plane... now has a new 2003 Ovation... but I couldn't fly it anyway if I still lived there. Min 750 hours reqd for insurance, plus too much $$ in that tier. Auto engines use O2 analyzers, which don't like leaded gasoline. My '88 Z car has 5 computers in it. At least 1 manages the engine timing and injectors. -- Ross On Wed, 25 Feb 2004 13:41:42 +0200, Stephen Jacobs wrote: >>>>>>> I agree with your endorsement of GAMI injectors.
