    Nearly the only thing that determines how hard a pump has to suck to get fuel is the difference in height between the outlet of the tank and the inlet of the engine. The lowest intake fuel port determines this number, not the number of lines. Rick, there is nothing complicated at all about Left - Right - Off. That is why there has never been a pile of aluminum laying on the ground with one empty tank of fuel, and one not so empty tank of fuel adding to the fire. Please remind those families that there is nothing complicated about Left - Right - Off. The point of my question was simply to ask why it is done this way in low wing aircraft; I know there must be some reason I am missing, which Bob, Linn, and Albert helped me understand. I for one will never stop asking why things are done the way they are. I am happy to know that your airplane has been built 100% per plans, you are a flawless robot of a pilot, and are at no risk of making me have to fight for my right to fly out of my field. Mistakes happen, there are defects in material and workmanship, and sometimes luck just isn't on our sides. Fortunately we have places like this to ask simple questions like these to help us understand why. Your absolutely right, the wheel is perfect, that is why I can't figure out why we ever invented wooden wheels, rubber wheels, then wheels filled with air, the stone wheel was perfect, it rolled just fine. If it ain't broke don't fix it, I get it, but I need to understand how and why. Sorry..... Thanks, Jason

    You can tie the tanks together with a transfer pump and timer. Requires one extra hole in your left tank unless you are already returning fuel back to the tank anyway. The cooling loop through the right tank is not needed with avgas.

Why can't a low wing airplane draw from both tanks at once? To me if the fuel is available at the inlet of the pump it should draw from both, just as well as a high wing with gravity working for it. Probably something obvious I am missing.... Has anyone ever considered using an electrically activated fuel selector valve like the ones used in dual fuel tank trucks? Switching tanks would then just be the flip of a switch. I think the failure mode of this device would be to stay open on whichever tank is selected. I will admit, complicating something as critical as fuel management any more than is absolutely necessary does make me nervous. Just got stuck on my brain for some reason..... Any thoughts?

Well, remember that what I said was in theory ..... In Albert's case, he unported his ONLY source of fuel at that point (I hope) since he probably has a left/right/off selector. I didn't think of that when I answered his email. The next time he does the slippy thing I'll bet he'll at least select the 'inside' tank!!! Another educational experience shared with the group. > I for one will never stop asking why things are done the way they are. I'm glad for that!!! I can't come up with all the questions!!! We're all still learning .... it's just that some have learned more than others. Your question was a good one ..... because the conventional wisdom just may be 'urban legend'. Out very tough job is to separate out the truth from the fiction (especially on a list) and arrive at a safe, sound, reasonable answer. The answer to your question just might have boiled down to: It's the 'safest' or 'simplest' or ..... whatever. I've never asked the question because I just accepted it. > I am happy to know that your airplane has been built 100% per plans, > you are a flawless robot of a pilot, and are at no risk of making me > have to fight for my right to fly out of my field.

I have learned to take what I perceive as a 'negative reaction' to an email with a grain of salt. I just give the writer the benefit of the doubt and attribute the 'nasty comment' to his having a bad day. Whether he had one or not just doesn't matter. To me, he was, and I'm the one that counts!!! And, it could have been ME that woke up on the wrong side of the bed ..... but I never do that!!! ;-) Linn do not archive > > Thanks, Jason > * > > *

    I made three trim tabs, the first was awful and I ordered another skin, the second was OK and the third try as they say was the charm. If I were to build them again I would build a mini rib for the ends and screw bending them. I think the real key to a good bend is making your blocks out of a good piece of hardwood and clamping them very tight so there is no way they can slip. After doing all the fiberglass stuff a composite rib for the end would be a piece of cake.

    Subject: Re: Fuel Selector
    I for one am happy to have the left/right/off as an option. It does one thing that a Both position doesn't....it ensures that I have full control over knowing what quantity is left in each of my tanks. With a both position, you may not know the exact quantity in each tank. The pressure coming out of the tank isn't just a function of the height of the tank outlet, but a function of the height of the column of fuel above it, and that column is a sloshing variable. As for the un-porting of fuel, it's a real problem, which is why many certified planes are placarded or have POH warnings about minimum takeoff fuel and such. Coordinated approaches are very important too, and while they teach you in your private pilots course that you can choose between crabbing on final and kicking the crab angle out at the last second, or slipping to keep the nose aligned with the runway, you really have to be wary of what you do when you're carrying less than 5 or maybe even 10 gallons in a tank. So that is why I personally love having just left/right/off, and not both. I have a totalizer and two float gauges, and can roughly mentally calculate my fuel levels that I should have burned. Keeping them isolated helps me ensure that I know more positively what my tanks hold. Incidently, even in high-wing planes, I think the "both" position perhaps promotes sloppy fuel management in some cases. Myself, I don't have rarely....extremely rarely, landed with less than 5 gallons of fuel in a tank. Maybe only 2 or 3 times, and 2 of them where when I purposely ran the tank dry having a near-full opposite tank. But, when I am on a long flight, I alternate fuel tanks a couple times during the flight and then as I get lower in quantity I keep one tank set to arrive in the terminal area with at least 10 gallons of fuel, whereas I don't mind at that point if the other tank has only 5 or 6 gallons left. But, being conservative, there have actually been very few times I've landed with under 16-18 gallons, because I set my high alarm to go off at 7 gallons per side. Fuel and spark are the 2 most important things to making it safely to the ground, as far as I can tell. It's funny that experimentals have such a nasty accident rate in the "fuel management" category. I can only wonder if this is because people tend to try to experiment on their fuel system, rather than just going with the old proven methods.

    Subject: Re: Fuel Selector
    Thanks for posting that Tim, It's kinda what I was trying to say but not as well written. There are certain things I feel you just shouldn't with, especially if it's not broke although I did use steel braided flex lines on my -10 but they have been proven to be reliable and I plan to have them on a time change item on my condition inmspections. If I were to do it again I may have only used the flex line from the fuselage side to the tank. It would be easier to replace. I think we need to just make sure we do it better than the certified fleet sometimes. The fiasco here in Vegas is a good reason for that. I was talking to an owner of a Aerocommander this weekend and he was so frustrated at the shop performing work on his aircraft, he went in and found a "kid", maybe 19 in his words "hacking" on his airplane. The shop has three "mechanics" and one A&P/ with IA that "supervises" all the others who are not certified. He was upset about the fact he is paying top dollar for A&P services but in the end, the A&P only makes sure it was done right and signs it off. Now I was a 19 year old aircraft mechanic at one point but I would bet that I had much more training and I know I had more direct supervsion than what was being described to me last weekend. The twin Baron (I think it was a Baron) that went down had very recently been in the shop for engine work...but they continue to focus on the experimental and student pilots as the high risk activities. I can only recall one accident related to training and that was few years ago and was the result of a stall spin after the engine failed during of all things..engine out procedures. I can tell you there have been a bunch of incidents related to certifed aircraft and I know of no other incidents except the Velocity for exp[erimentals at VGT. Guess I rambled but we can't afford to not do it better than everyone else when it comes to experimental aviation. The fuel management issue still amazes me because a large percentage of that is a result of flying with air in the tanks.

    Subject: Re: Fuel Selector
    Regarding the braided lines....I don't think that in that case it's quite the same as changing the fuel distribution method. With the lines, I actually think there's a good argument that the braided lines will be more reliable and basically immune to flex fatigue cracking, whereas there are many of us who found first-hand that there have been bad batches of aluminum tubing from Van's in that 3/8" size. (and even the good batches aren't necessarily all that fantastic) I think that probably the best someone can do would be to use conductive teflon lines that are overbraided with stainless and have anti-chafe covering. That would probably be the ideal. The drawback to the braided lines is just weight. The additional drawback to the various rubber type braided lines is even more weight, and a life limit. But those things aren't really in the same ballpark as some of the other mods. After all, what kind of lines are used from the firewall forward? No matter what kind of lines are used, they need protection, and need to be well secured. I actually plan at some point to replace my lines with braided conductive teflon, and go all the way from tank to firewall that way with some exceptions. Regarding that maintenance fiasco, I think that's just another example of how businesses react with payroll when the economy tightens...not to mention our ever decreasing worker quality that the country produces. It amazes me how poor the work ethic is in many of the people that are turned out today. I know when we go hiring, the "Good help is hard to find" saying really holds true. Funny that unemployment is starting to be such a big thing again, yet around here we really have trouble finding top notch skills. Sorry for the rambling, but yep Rick, you're preaching to the choir. If the news could only be balanced and give perspective to crash reporting, people would have an entirely different opinion about flying.

    Subject: Engine mounting ear nut torque
    Checked the archives with no luck, can't seem to find any info in engine documentation, therefore does anybody know the torque required for the nuts which hold the ears on the IO-540-D4A5 ? Its a 3/8 stud so does the usual torque number apply? Thanks Chris Lucas #40072

    Subject: Re: Indicator lights - what functions to include
    The EFIS warning is tripped by things like terrain alerts, obstacles etc. That alert can be re-set (or acknowledged) from the EFIS. However ANY warnings generated by the EIS must be cleared by the front buttons on the EIS or as I found out the hard way several years ago with a remote line out the back of the EIS to a button. The EIS goes back to GRT for this addition. I ran my wire into a db9 since it's just one wire sticking out the back of the EIS. David W.

    You might try bending them as closely as possible and then making them perfect with a dab or swipe of superfil and a little sanding/shaping. -------- Myron Nelson Mesa, AZ Emp completed, legacy build fuse in progress Read this topic online here: http://forums.matronics.com/viewtopic.php?p=219028#219028

    From: "woxofswa" <woxof@aol.com>
    I am doing the fuselage first and it has worked out fine so far. One of my concerns was simply storing the wings during the much longer fuselage build, and dealing with spiders, rodents, moisture, et-cetera. -------- Myron Nelson Mesa, AZ Emp completed, legacy build fuse in progress Read this topic online here: http://forums.matronics.com/viewtopic.php?p=219030#219030
