The Special Airworthiness certificate issued to each amateur built experimental aircraft includes Operating Limitations for that aircraft. The Operating Limitations will include the following sentence: "After completion of phase I flight testing, unless appropriately equipped for night and/or instrument flight in accordance with 91.205, this aircraft is to be operated under VFR, day only." The FAA policy regarding this sentence is: 1) If the aircraft is flown day VFR only it does not need to meet any of the instrumentation or equipment requirements of FAR Sec. 91.205. 2) If the aircraft is flown VFR at night it must comply with the requirements of FAR Sec. 91.205 (b) and (c). 3) If the aircraft is flown IFR it must comply with the requirements of FAR Sec. 91.205 (b), (c), and (d). These three FAR paragraphs list the instrumentation and equipment required for day VFR, night VFR, and IFR respectively. In addition: 1) FAR Sec. 91.207 lists flight conditions under which aircraft must have ELT's. 2) FAR Sec. 91.215 lists flight conditions under which aircraft must have transponders. Amateur built experimental aircraft are not excused from either of these two equipment requirements in those applicable flight conditions OC ________________________________ Message 2 _____________________________________ Time: 02:50:22 AM PST US From: "Mike & Lee Anne Wiebe" Subject: RE: AeroElectric-List: EFIS Backup Battery and fuseblocks - Attn Bob --> AeroElectric-List message posted by: "Mike & Lee Anne Wiebe" Thanks Charlie - good start!

On top of that, it has been my experience that the best backups are multiple sources that are in constant use. The drop out (or push out) wind driven generators cost at least as much as a B&C standby unit. The B&C provides a full time source of power. It will even help out an overloaded primary power source then go back to rest when it is no longer needed. It may even weigh less! I think that a full time second alternator would be much more reliable than something that had to be activated by the pilot.

The older style has 3 connection points. #1 The contact surface between the fuse's blade and the female contact in the block. #2 The male/female fast on connection #3 The crimp on the female fast on connection at the wire These new style blocks do not have the #2 connection, so there are only 2 connections rather than 3. The connectors used on these fuse blocks are open barrel style connectors, like Molex connectors. Since you will most likely be purchasing or borrowing a crimper to do the Molex or Amp style connectors on your project, use of this block will not require the purchase of additional tools. The female end of the connectors makes direct contact with the fuse. This is an advantage, not a disadvantage in my view. With the older marine style blocks, it the connection between the fuse and the block fails or develops high resistance, you must scrap the entire fuse block. With this new style, you simply replace the offending connector. The new blocks also save space. Note that the older "fast on" style 10 fuse block is physically nearly as large as the newer 20 fuse style. For those of us with space considerations, this is valuable. MIH sells you the block, a great selection of the connectors and the tool to release the connectors from the block for $38. Having the wires exit the rear allows for a much neater wiring harness. The new block can be flush as well as surface mounted. The cover will prevent accidental contact with metal objects. See attached photos for mounting ideas. Your mounting options using this style of block are increased. I am still using the older style block for my battery bus, as I only need 6 fuses on this bus. Charlie PS Those of you reading this via the list will not see the photos. The list will strip them out. If interested, contact me "off list". >Thanks Charlie - good start!

The 'Dawn Patrol' guys in KC (flying VW powered WW-I replicas) discovered that a chainsaw motor made an extremely lightweight starter for their engines & kept them from needing batteries & charging systems. Pull the rope, rev it up, VW starts, shut down the chainsaw motor. Now, what if the little 4hp engine Eric speaks of had a pilot controllable clutch to a starter gear in addition to the aux alternator? Most new ideas are worthless. But if we didn't look at all 100%, we'd miss the good ones. Charlie ________________________________ Message 7 _____________________________________ Time: 07:06:26 AM PST US From: "Eric M.

In the yard, frozen solid under three feet of ice and snow, sleeps my Craftsman lawn mower. The gas is slowly going bad, there is water in the crankcase--AND it will start on the second pull this Spring. Odd as it may seem (and perhaps without gas), there is no on-going degradation that will prevent the motor from starting decades from now. Which is most reliable and cost effective in a particular situation? I don't know--but the APU will go for many years. It will cost more in the beginning, but cost less in the end. >>>> Repost from 1/11/04 so (Do Not Archive) <<<< >From: Ian (jabiru22@yahoo.com.au) >Not sure if you have seen this, though I thought that it was interesting >/index.asp >Ian This deployable wind driven generator has been around for a while, as have others. On sailboats a WDG is all you've got. This one has the benefit of being deployable and compact and apparently powerful enough to do the job. BUT I don't own stock in the company so I propose some questions for discussion: 1) Isn't a small spare alternator really a much better way to go? 2) If you read the testimonials; isn't deciding to take off on your back-up electrical system ill-advised? 3) If the device will get you out of a jam in IMC, isn't icing a concern? 4) If 3) is yes, how about an exhaust driven turbo-generator to replace the muffler? (As usual I'll take my 10% fee for the idea.) 5) My own similar design (paper only) is made from a NACA duct and a turbine wheel from an upright vacuum cleaner. 6) Doesn't Bob have eight ways to do this job? Are they (as I suspect) better? For extra credit explain why. Compare and contrast the systems. Regards, Eric M.

Charlie Good Afternoon Charlie, Please don't get me wrong! I agree wholeheartedly with the basic philosophy. For one thing, an APU is nice to have when you are stuck in the boonies. I would carry a Honda Generator if I were flying in the bush with no close by support. The tiny APU sounds like a great idea in principle. It just seems that the extra alternator doesn't really require an extra engine to drive it when we are considering nothing other than extending the flight time. For a backup electrical supply in the bush, it would be tremendous!.

I hope this clears up some of the concerns you have. BTW, they come with a cover that snaps on the block and covers the fuses.

I have a Makita 14.4v drill and its 2.2 ah batter has died. I went to the hardware store to get another one only to find that they were 80.00, which is half the cost of a new drill with 2 batteries.

The link I provided was for a "backup" alternator but most of the pictures on the web site shows it mounted in such a way that it would always be in the airflow and therefore turning. I thought it was interesting because it could be "deployed" via a door AND because the Eggenfellner package cannot accomodate a second engine driven alternator. If I find that my dual batteries need to be mounted aft of the baggage area for W&B considerations (RV7A with Egg H6), would you consider it advisable/wise/practical to mount the two engine busses (fuse blocks) next to the rear batteries and then run several fused wires forward for ECM, fuel pumps etc?

The drop out (or push out) wind driven generators cost at least as much as a B&C standby unit. The B&C provides a full time source of power. It will even help out an overloaded primary power source then go back to rest when it is no longer needed. It may even weigh less! I think that a full time second alternator would be much more reliable than something that had to be activated by the pilot.

I got lots of hits, but I don't know exactly what your battery looks like.

I have a Makita 14.4v drill and its 2.2 ah batter has died. I went to the hardware store to get another one only to find that they were 80.00, which is half the cost of a new drill with 2 batteries. > >Does anyone know of a third party supplier, or a supplier that opens up the old battery packs and replaces the cells. > >Thanks, Paul > > > > ________________________________ Message 17 ____________________________________ Time: 03:21:29 PM PST US From: Mickey Coggins Subject: Re: AeroElectric-List: Re: APU vs battery --> AeroElectric-List message posted by: Mickey Coggins Hi Bevan, That's what I did: http://www.rv8.ch/article.php?story=20050112132057110 Mickey > > If I find that my dual batteries need to be mounted aft of the baggage area > for W&B considerations (RV7A with Egg H6), would you consider it > advisable/wise/practical to mount the two engine busses (fuse blocks) next > to the rear batteries and then run several fused wires forward for ECM, > fuel pumps etc?

I took it to a place called "Batteries Plus" in Boise, Idaho and they replaced the batteries inside of the pack. I think it was about $30.00.

By now there might even be some product available. It does not seem to be a big development shift to have this technology provide back up for batteries or for power backed up by batteries depending upon the variables of personal approach and mission requirements etc. Fuel cells can be configured to burn alcohol, hydrogen among a list ? of other fuels Why not avgas? Is there anyone out there up to date with small fuel cell technology current (no pun intended) and future.

I want to use LED Nav lights on my RV-10. I was thinking of getting the Creative Air kit....but I'm not too fond of the "circuit board" look to them. Then I saw the perihelion ones that look like they might look nicer, but they have fewer LED's. A 2nd issue is that the Van's Rv-10 wingtips are cut about 110 degrees of visible area, whereas the regs say you need 120 I believe. So, if I got the Creative Air ones, and mounted them as shown on their site, I think the light angle will be insufficient to the rear. To come up with the ideal, I thought maybe I'd take a stab at designing a custom layout, where I have some LED's on the back of the sheared tip area, and some on the sidewall where the strobes will mount. But, I had a design question to start with... I see that people are advertising theirs with current control regulators in the circuits...what benefit is this in an LED Nav light situation? Can't someone just use the individual LED + resistor arrangement, or is there something else I'm not thinking of? -- Tim Olson -- RV-10 #170 ________________________________ Message 25 ____________________________________ Time: 11:42:49 PM PST US From: "Stein Bruch" Subject: RE: AeroElectric-List: RG58 vs RG400 Coax Cable --> AeroElectric-List message posted by: "Stein Bruch" Definately YES...it's worth it. RG-400 is superior in many ways. Check the archives or some of Bob's in depth analysis for review, but it's much better to skip a couple big mac's than to skip the RG-400. Better Shielding, Better Conductor and superior jacket are a few. Just out of curiosity, I went and weighed a 1,000' spool of RG-400 a few minutes ago. It weighed 44lbs, which is pretty close to the actual Mil spec, which states 42lbs/MFT (per 1K). Most distributors/mfgs quote 50lbs/MFT, but the actual Mil Spec reads 42 so the real numbers are somewhere between 42-50lbs/MFT. Just my 2 cents as usual!
