The valve should be a high pressure valve, that is they usually isolate the tank from everything else, and a leaking tank is very unusual but possible I guess where the valve threads into the tank. Sometimes the tank pressure gauge is before the valve so tank pressure is always displayed, even with the system off. ‘ A leak is easy to find, it’s accessing the system if it’s a built in that may be difficult. ‘Soapy water is likely safe and OK, but I would advise to use the special leak detection fluid for O2 systems, yes it’s just soapy water, but it’s safe soap. My luck if I didn’t I’d find some kind of soap that had oil in it. But usually it’s the tank with a valve connected directly to it, and the regulator connected to that valve, after the reg of course it’s low pressure. If it leaks only when the system is on, then it’s most likely a low pressure leak or the regulator itself of course, maybe they left a fitting to the reg loose?

Most of my just out to fly for fun is done then in any airframe, smooth air is so much more pleasant. ‘I wonder how well they handle cross winds?

I’m not saying it will be smooth or to continue flight, just that it will probably run without tearing any mounts up. ‘A 6 running on five isn’t smooth either, has you pushing the nearest button on the GPS, even my C-85 will run on three, but not smoothly, I had a bad plug and on one mag it was only on three is how I know. ‘But engines are different, blow a jug off of a 985 and it will continue to run, blow a jug on a 1340 and it won’t, so saying a C-85 will run on three doesn’t meant that a Lycoming 360 will, but I believe it will. They will run with a stuck valve or broken rings, just not well. ‘Of course you handle it however you want, just in the C-210 with its IO-520, making it run slobbering rich meant high manifold pressure to maintain level flight, couple that with the lean cylinder running excessively high EGT. After thought it was better to just let the clogged one lean out and quit, but if you don’t like that, push the red knob back in and or turn on the boost pump. ‘On our Lycomings I don’t think turning on the boost richens up the mixture like high boost on an IO-520 anyway, so all you can do is go full rich, the big Continental with high boost, you can make it slobbering rich, like a car with the choke on, so I guess that the difference. I guess the takeaway is if a plugged injector puts a cylinder near peak EGT, be careful of high manifold pressures is all, and if you can’t avoid high manifold pressures and it looks like it may be headed for detonation, let it go so lean that it can’t detonate is a way to deal with a plugged injector.

You’ll get two certificates or three if it takes that. ‘I think if my knees would allow it I’d like to try the backpack motor ones, but the big trikes I don’t understand, but sure why not, I got a sea plane rating just for fun,it’s not likely I’ll ever use it, but it was fun. Report back, I’d like to hear if it’s fun or if it gets boring ‘No, I’ve never flown a PPC

Yeah, keep think your smarter than everybody else and your special. If your basing your numbers on outliers good luck with that, keep thinking averages don’t matter, all those other people are fools, your smarter than all the people on the Cessna twin site, what the Hell do 250 Cessna twin owners know, right? How is it that you guys can think that flying two engines with two props, two of everything only cost just a little more than one? Explain that logic, do engines and props have longer TBO’s or cost less, maybe your getting a break buying two at a time? Using your logic then us single engine guys are stupid, why fly a single when a twin is just a little bit more? Maybe that’s why you see so many twins flying right? I mean they out number the singles don’t they? So what’s stopping you? Go buy a twin, why are you flying that tiny little airplane? ‘Use your brain, if they were so economical, you would see a whole lot more of them, and there woud be a whole lot more in production, but there isn’t, why do you think that is? Why aren’t most new aircraft twins? So which twin do you fly?

Their average was closer to $360, average it out and see. ‘Then you pay $60 an hour for fuel? My last fuel delivery was $3.85 a gl, I burn about 8 gl an hour, often less but use 8. That times 3.85 is just under $31. ‘What do you pay for fuel and or what’s your fuel burn? So anyway based on what I saw in this forum it seems $120 is about what they say, which is almost exactly 1/3 what the Cessna guys say. ‘I don’t know what it cost to fly to be truthful. it costs what it costs. I’m an A&P, own my own hanger etc, etc, plus I don’t put costs down, besides it’s not what it costs me, or you. The point is what does it cost on average. ‘One data point is irrelevant. The Cessna site had I think 250 respondents that they averaged out, and many were A&P/IA’s too and that skews costs for those that aren’t.

You guys are wanting to cheery pick and skew results. Click on the link, read it. No one says anything about pressurized 421’s, it was C-310 specific https://twincessna.org/pdf/What Does it Cost to Own a 310 in 2020.pdf Compare what they say the costs are to the average J model Mooney, I say J as it’s the average, ordinary Mooney, ‘get the average cost of the Mooney off of this site, I’m sure it’s somewhere. Only two conclusions are logical, either the guys on the Cessna site are full of it and are wrong, or it cost three times as much to operate a C-310 than the average J model

Yeah, I read that on their site, as I said it’s amazing how many people will spend their time and money, to make others money, because you know someone is making money from that, how I’m not sure. ‘You do what you can I guess, I’m just astonished it’s legal, so far as I know you can’t do that with automobiles etc.

Yep you guys are right, the guys over there on twincessna.org are doing it all wrong, they don’t know what it cost to own and fly their aircraft.

First time it happened to me on the 210, I went full rich and boost on to try to keep temps on that cyl down. After the first time of doing all of that I didn’t richen up, boost etc, just let that cylinder lean out and die,of course it cooled way off then, and I wasn’t slobbering the others with fuel. Seems to be a better way of dealing with it. ‘Of course that was a 6 cyl, but I believe even a four will run OK smooth on three A handheld IR thermometer will find the bad cylinder instantly for those that may not have an engine monitor, even your hand usually will. ‘Monitors are nice to have, it’s maybe my next purchase, I’ll go with the UBG-16 because the owner is a friend.

I don’t have the tooling like I used to, and I got spoiled working in a aircraft factory where pieces parts and machinists / welders etc was free. ‘I’m also airplane poor at the moment so today I’m going to Lowe’s and buying some pipe and knocking something easy together and use the golf cart, just have to be real careful and I assume I’ll be OK. ‘Both my knees are shot, really years beyond needing replacing and I can’t do Sun-N-Fun because of it, been afraid of the surgery and waiting until the replacements get better and me to be old enough so a set ought to last the rest of my life, so pulling an airplane by hand is way harder on me than it used to be, yesterday I got the Mooney out so I could fly the 140 around and my knees hurt so bad I didn’t sleep well last night, so off to Lowe’s I go. Eventually I may buy Don Muncy’s tow bar once funds free up. I hope it’s Ok to say that, it’s several hundred dollars cheaper than most alternatives and his colors worked out well for me.

Ref C-310 costs per hour to fly, about $350 to $400 an hour? What's it cost to fly a Mooney? https://twincessna.org/pdf/What Does it Cost to Own a 310 in 2020.pdf Go argue with them, cause they clearly are frauds and don’t know what they are talking about. Then use this place as a reference for a J model,

Sure you guys go buy your old twins and fly them on less than it cost to fly a Mooney. See how long it takes that bubble to burst, if you have a six figure fund to cover the gotcha you’ll be fine, maybe. You did defer maintenance as by your own admission you only overhauled one engine in that time, and overflew a TBO, if overflying TBO isn’t deferring maintenance, then please tell me what your definition of deferring maintenance is? Yeah, I’m just an old fat guy in his Mama’s house, I’ve not been a professional pilot and mechanic since 1982, not like you real Pro’s. And no. I’m not posting my personal data just to become some kind of internet celebrity. Like I said, reach out to AOPA or believe that those sources are delusional if you want to, and you can if fact fly a much more expensive airplane for less money, it’s just all the suckers that don’t know that. Anyone can get lucky flipping houses or boats or airplanes, most it eventually catches up to them, some it doesn’t. Some smoke their whole lives and get away with it, you can’t determine trends from one case.

Surely there are good websites that compute cost of ownership? Maybe AOPA does?

Owning an airplane or car or boat for a year or two doesn’t reflect cost of ownership. You’ll of course argue that you didn’t defer maintenance, but you did. ‘Guy I bought my airplane from owned it for a couple of years and flew it a few hundred hours and stated it only cost him the Annuals. ‘So we can infer from that, that owning a M20J if flown 200 hours a year and an Annual cost $2,000 is only $10 an hour. ‘Try to explain that the engine cost alone is more than twice that, to say nothing of the prop etc and he’ll say it’s not true, I did it on only $10 an hour. Normally you’ll take the hit in depreciation on sale, but if your lucky or smart or whatever you ascribe to be, you may buy low and sell high and not take the hit. ‘For instance I met a couple that bought houses and fixed them up while living in them for a year or two and resold them, and always made money on the deal, this was before 2008 though. I wasn’t there but I’d bet lunch that came to a ugly end in 08 though

Looked up the ADSB exchange thing, there are a lot of nuts out there willing to spend their own money and time to make some people they will never meet money I guess. Brave New World I guess

So where do they get the data? Do they have their own receivers? Surely the registration data is FAA? Why do they exist? what’s the purpose? Who funds them?

A way to test if fuel contaminants are biological is to put bleach on it and see if it reacts, changes color. Jet fuel and Diesel trick because they can get asphaltanes and make some think they have “bugs” Does anything grow in Avgas? I don’t think anything does? ‘Fuel truck filter breaking down is the most logical to me, but I cannot explain it being on the wrong side of the screen. Anything that happens to a motor can’t get into the fuel

No one answers the phone anymore, the Dr. office no one, well I guess us old farts do but the rest of the world txts and sends emails. ‘Maybe it’s all of the Spam calls? I guess you need to go there and see them, your going to do that anyway, I’d fly there at least then they know your st least a pilot. The other thing about kids is they are unrealistic, worse than we were as kids, the kid that delivered propane to my house stated he was going to get his helicopter license. In other words it’s real likely 99 out of 100 calls are unrealistic dreamers, after awhile you just quit listening. Fly in in your airplane and you’ll probably get a different response.

I’ve been very pleased with this. just buy a spray bottle or reuse one, but $14 for a half gallon and it works well.

Interesting, yes that was part of the ILS, but only part. I had a squawk and was up approach for the whole arc, missed etc. ‘Wonder if that was a fluke, or are they receiving ADSB themselves and not relying on the the FAA to provide data? Just looked and there is no history available for all of March and only the 6th of Apr? I’ve of course flown more than that

121.5 and 243.0 ELT’s are worthless, no one even monitors the frequencies anymore, but you have to have something, Congress said so.

Had a C-210 that did it regularly enough that I flew with a can of carb cleaner and wrench and deep well socket. ‘The can of carb cleaner with the straw works really well, just be darned sure none sprays back into your eye, you’ll only let that happen once. ‘Ended up being a fuel hose coming apart, pull screens and if you find what looks like little black granules I bet that’s it.

No, actually he’s correct, it’s absolutely the least damaging way to clean plexiglass, even a micro fiber towel will trap dirt and or insect exoskeletons and that will scratch the window, your hand won’t trap it and you can feel it it’s there. Ideally a clean hand with flowing fresh water for the initial cleaning, followed with some mild soap, once clean and dry then go with the plexus or favorite plastic polish. First your trying to remove the dirt etc without causing any damage, then once clean, polish if desired or Rain-X whatever. Rain-X from my experience is excellent and doesn’t hurt anything, and rain just flies off of it. I don’t fly in icing, but have wondered if it helps there? The pledge was a trick I learned in the Army, the theory is it fills in scratches so you don’t see them.

There is no free lunch, so a winglet shifts the lift vector forward and develops thrust, but not more thrust than there is drag, so it’s a reduction in drag, but the drag still exceeds the thrust, other wise it’s a perpetual motion machine ‘Of course a winglet works better at high angles of attack, so on a GA airplane like ours there is only added weight and drag as we don’t fly in cruise at high angles of attack. ‘I know we aren’t talking specifically about winglets, but in truth we are, as he said, take a winglet 1/3 wingspan and lay it flat. ‘To make his proposition most useful, you dump the fuselage, maybe have a blended body like a B-2, but no tubular fuselage like we are used to, and no rudder. he didn’t say no tail. but i’d suspect that’s the eventual end. Who knows, maybe we will live to see one, and maybe we will live to see average people flying above Mach 1, it could happen, but I don't think so. I’m surprised Gulfstream didn’t build a Supersonic “business” jet years ago, I know they were working on one, the lead Engineer died in a crash at Sun-N-Fun years ago, I know nothing about the crash though, just that it occurred. On edit, easier to find than I thought. https://www.wtoc.com/story/8160702/fl-plane-crash-kills-gulfstream-employee/
