Perhaps the Biggest reason why LOP can reduce fuel consumption is the basic operating principle of how an internal combustion engine operates. ‘Engines do not develop power from the pressure from “explosions” as many think, they develop power from the rapid expansion of heating a gas (air) Within reason of course if you reduce the ratio of air to fuel and still generate the heat, your increasing the amount of gas to expand when compared to the amount of fuel it takes to expand it. Fuel enrichment at high power isn’t so much to do with being required to make the power, it’s required to make the power without overheating the engine ‘Those of you that are bumping the timing up are playing with fire, I disagree with the plus or minus 5 degrees of timing won’t make much difference, it will make big differences, increasing timing will certainly increase power, but your reducing your margin for detonation.

Many Ag aircraft will use roads or fertilize trees etc.,but they are most often old and or abandoned farm roads. Fertilizing trees means you empty the hopper in a very short time, so if you can cut ferry time you can get a lot more work done

OK, I deleted the Screen shot. However if any think having their personal data freely posted by the US Government is an invasion of privacy, they ought to complain. ‘I know many did in IA conferences to the FAA,but they pretty much laughed at us when we did, one even told me that if I didn’t want Flight Aware posting my current whereabouts to hire a Lawyer and have him petition each agency to not do so. That’s how I learned how the wealthy and celebrities do it.

Original owner, not sure how long it takes the FAA to change their records? Title company was supposed to have it changed the day the aircraft was sold. I’ve tried unsuccessfully to get the address changed for the 140, but it’s not posted either, and the FAA wonders why their registration database is still a mess. ‘For those that are interested, I was offered the LLC along with the aircraft, PO had done that, if you purchase the LLC and the assets of the LLC are the aircraft, apparently there is no tax due. Dosent sound right, but apparently it’s true and legal, but I didn’t want a Ga. LLC

This web site is moderated I’m sure they all are, I’m a moderator in a huge one called Cruisers Forum. ‘The Mods whoever they are can of course take the post down or moderate it. But without posting his name etc, how do you ask the question of does anyone know this guy?

Then they are breaking the law, don’t believe me, look it up, I too was breaking the law and got away with it until we opened an account for the Wife, that’s when they caught it. ‘I’m going to guess some kind of list exists that has mail forwarding address that gets checked now, that didn’t get checked originally, or maybe it’s just new accounts that get checked? Cause my accounts had existed for decades, since I was Military, who knows? Here is the law, it’s in there somewhere among all the legalese https://www.treasury.gov/resource-center/terrorist-illicit-finance/Terrorist-Finance-Tracking/Documents/staterule.pdf Ai a glance it seems new accounts will trip them looking, existing accounts prior to the law, maybe not.

yes, but your not required to have your AIS on, and there is even a way to turn the transmit off, plus it’s not tied to you in an easy to search government database for all to see. Commercial vessels are required or have it on, but often don’t. Fishermen don’t want to advertise where they are fishing for example. There are places cruisers go that your speed, direction vessel type and location you don’t want broadcasted, even in the America’s. Many things come to boats first then aviation later, EPIRBS is one and as you note AIS is the other, you don’t get weather on AIS though.

I don’t think it’s better, I was showing it’s not as you say it still has my name on it. ‘We have sold the boat and are dirt dwellers again, and I bought the Mooney with a Montana LLC, which would be tough to tie to me. Government can of course, but some criminal can’t look at flight aware and know I’m not home, out of State etc. which would be real easy for one to do if I had my house address on the registration, there are other reasons of course that’s just one. ‘I got away with SBI as an address for USAA, but when we went to open an account for my Wife, they “caught on”. USAA was going to cancel my accounts that I’ve had with them for decades, the statement of domicile didn’t satisfy the requirement, nor did voter registration cards, law says you MUST have a physical address. a Quick Google brought this up along with the law of course which is real hard to read so I didn’t link to it. https://www.fcnbank.com/patriot-act/

Depends on where you are, in Alaska and the NWT it’s common and normal. there are even restaurants on the side of the Alaska Highway as you fly by that will have aircraft in the parking lot, and a few gas stations with extra long hoses that you land and taxi in and fill up with car gas. ‘There used to be a Marina in the Panhandle of Fl that was out on the end of a causeway, you would call them on the VHF and a VW van would run out and place a saw horse across the road and you would land and taxi in and park to eat, when you went to leave the process worked in reverse. ‘I’ve stopped and stayed here several times, you don’t land on the road but you do taxi down it to park the airplane in the grass just across the street from the Motel, be sure to stop at the stop sign before you cross the main street. https://www.funplacestofly.com/funflydetails.asp?id=411. But most other places the local LEO will ticket you for operating a motor vehicle in an unsafe manner and the FAA will get you for being reckless and dangerous. In flight school in the Army we had a classmate that just disappeared one day, turns out he had run his Piper out of fuel and landed successfully in the parking lot of the Super Bowl. The FAA apparently got upset when he got some car gas in a can and flew it out of there. At least that was the story that was going around.

Book speeds for any aircraft don’t mean much, Book speed for my M20J is 175 kts and on my pre purchase test flight I did get 168 out of it full throttle and 2,000 MSL at 2600 RPM, and burning 19 GPH. ‘But who will ever fly like that? I can get 150 kts LOP at altitude, burning 8 GPH, or 160 not LOP and burning 11 GPH. I assume the airplane your looking at will achieve similar results, with slightly different numbers, but if your expecting “book” numbers you won’t be happy, and if you run it that hard, it’s likely you won’t be happy either

I would do this, but it’s going to take a structures DER and your going to spend some money determining load paths and stresses etc., and even then in truth it’s going to be an educated guess, so a good DER will leave good margin. But he’s going to need some measurements of course, unlikely he will travel to the airplane. 10% is a generic answer for anything, like 4130 tubing for example and takes nothing into consideration. ‘If you had bought an annual and not a pre-buy then you would have some recourse for them missing it, but as a pre buy isn’t a defined term, it has no standards that a shop can be held to.

There are separate, independent bladders that are connected to each other in each wing. I have three in each wing and I believe on a J model that there could be four.

Surely people realize that Amazon does not sell aircraft parts?

Still has your name on it. ‘This is my C-140. There are hundreds, maybe thousands of people with 411 Walnut St Green Cove springs address. ‘It’s a mail forwarding agency that’s used by people who live on a boat and cruise and have no address, Also many RV’s and quite a few traveling contract Nurses etc. ‘It gives you a legal address, and will establish you as a Florida resident, and allows you to vote etc. Fl has this figured out, for example the address on my Fl drivers license was the Coast Guard registration number for my boat, I had on file at the Clay County Courthouse a “document of domicile” that named my boat as my domicile. ‘However since 911 the Patriot act doesn’t allow you not have a physical land address, and they know about the mail forwarding agencies, so I was not allowed to have a bank account etc., so we were forced to lie and use a family members address, USAA knows all about this, that address was not used to send any mail to etc., it was only to satisfy the Federal Government. ’Funny thing is, your allowed to live in a box under the main street bridge, but your not allowed by the US Govenment to live in an RV or on a boat. This combats terrorism?

Very few actually. ‘My Company made the power levers that are used in the Predator B or “reaper” which uses a Honeywell G10 turbine, the old piston predator is pretty much retired, my be all gone I don’t know. So I could infer about how many Predator B’s were being built by how many power levers we sold, and it’s a lot more than I thought. Lycoming did build a spark ignition jet fuel engine for some kind of drone as the Military has been one fuel forever, the last use of gasoline in the Army was the cook stove, and it went away in the 90’s? Replaced by I’m sure one that burns JP-8, which is Jet-A. The Lycoming motor is some kind of small motor I think. https://www.lycoming.com/engines/el-005 ‘Mercury outboards also built a spark ignition outboard that burns jet fuel, likely JP5 for special ops, as gasoline is not at all what the navy wants onboard, http://www.marineenginedigest.com/profiles/mercury/Mercury-Optimax-Military-Motor.htm in fact before I could conduct carrier quals in an AH-64 long ago we had to burn three tanks of JP5 through the aircraft before we were allowed aboard, even Jet-A is too explosive for them, gasoline is an absolute no-no

Found an article specific to aircraft https://blog.aopa.org/aopa/2015/04/13/destroy-your-engine/

99 % of the “valve” rattle and knocking we hear isn’t detonation. it’s pre-ignition. 70’s cars were the worst. pre-ignition isn’t usually all that harmful. ‘Thankfully detonation is rare, most likely you have never heard or experienced it, very often even short duration detonation is destructive

The cylinder heads do run cooler, often much cooler, but it’s largely due to the lower power output as cyl head temp follows power output pretty closely. ‘LOP does work, however it’s for low power, don’t believe that it’s not, no gasoline piston engine that I’m aware of doesn’t go into “power enrichment” when run at high power, even the newer computerized fuel injected outboards, that excess fuel does help cool, it’s not needed to make more power, it’s needed to keep the temps in control. So I’m thinking the marketing dept made that decision, because run one LOP and it’s not the “Hot Rod” it is ROP. Lycoming doesn’t recommend LOP, in my opinion that’s not because it doesn’t work, but because the power loss in a Lycoming is quite large, that may be due to lower swirl in a Lycoming combustion chamber. Swirl is something that’s pretty new, it wasn’t thought about back in the day when Hemi combustion chambers were the hot ticket. One day maybe airplanes will have Pentroof combustion chambers and four valve heads, but I’m not holding my breath. So if LOP is used as an economy measure, which also means lower power and slower speed, it won’t do any harm, and in fact I believe a solid argument could be made that an engine operated that way will outlive one run at high power, rich and higher cyl head temps, of course that guy is going much faster and a counter argument could be made he’s running his motor for less hours I guess. ‘It’s when people try to recover the power lost from running LOP that bad things can happen, face it, yes it can be done with modern computer controlled engines with knock sensors in the manifold and the ability to independently adjust each fuel injector and vary ignition timing independently for each cylinder, but for our maybe 1940’s engines? Maybe not. We think with engine monitors we have all the data to do it, but compared to a microprocessor hooked to a knock sensor and an O2 sensor in the exhaust and learning ability to build injection and timing “maps”, we just can’t possibly run at the edge like those motors can.

Were it not available to any and all, I’d agree, but the FAA has determined for whatever reason that aircraft owners are allowed zero privacy, registration is openly available as well as our every flight, because your not allowed to turn off your ADSB. If it bothers you, and I think it should, make your complaints to those that might could make a change, elected officials. AOPA etc.

Wow, did you read that? I’m going out in a limb and going to say that the issue was foreign nationals drug trafficking and other illegal activities, not LLC’s

cut and pasted from here https://www.49dollarmontanaregisteredagent.com/vehicle-llc Maybe they are lying, and I’m certain a court order gets all your info, but John Q. public isn’t. ‘They do aircraft too, aircraft are less expensive and easier as there is no license tag, title etc. Benefits of Using a Montana LLC to Own an RV: Remain anonymous. When you hire us to form your Montana LLC, we keep your personal name off public record. Keep your license plate information private. Anyone can look up a license plate number and get the same and address of who the vehicle is licensed to. If you have a Montana LLC own your RV or motor home, they find your company name and address. License plate lookup. Anyone can look up a license plate number and get the name and address of who that vehicle is registered to. The privacy of this alone is worth the whole process. It’s time to play with the rules the rich created. Loopholes, loopholes, loopholes. Our laws are written by people who have the money to buy lobbyists–people who basically buy and sell laws that they have interest in. The middle class gets stuck playing with the rules the rich have written for themselves. You finally have a loophole now that you can use to make the cost of owning and RV less. Data. If you own an RV in your personal name, your personal name gets associated with assets. Data aggregating companies will get your data from public registrations, associate you with a certain amount of assets, and sell your information over and over and over again, so that company after company can proposition you with offers to buy stuff. By not owning an RV personally, you can keep your personal name from being associated with assets, and you will reduce the amount of solicitations you would get otherwise.

I’ll run LOP myself often but I do so only at lower power. What bothers me is when I read that you can run high power LOP. You can go fast, or you can run LOP but you can’t go fast, LOP. Much of the fuel saving from running LOP is actually from slowing down, but who cares why, so long as you burn less to cover the same distance. Detonation destroys engines, so avoid operations that may allow it, I won’t bump my timing up either, although I’m sure you can get away with it, it reduces the margin. Lycoming is a different combustion chamber design than Continental, and I suspect just from listening to some of the Continental’s idle they have a more radical a profile too. The 210’s 520 loped like a dragster. I used to love to hear it idle. ‘Point is I think Continental engines work better LOP than Lycoming, or at least a 520 works better than a 540, I can’t speak for others, but my 360 without Gami’s runs smoother leaner than my 540 did, maybe it was because the 540 was a parallel valve motor?

This does a decent job of explaining detonation, but it should be noted that detonation can occur at pretty much anytime there is fuel, air and compression, to include even after the spark plug has fired, however that detonation is not usually as destructive as often the piston is on its way down and combustion chamber volume is increasing. It’s most destructive if max pressure occurs prior to TDC as that blows pressure and heat through the roof, because there is no where for it to go. https://www.procharger.com/what-detonation-and-how-can-it-be-controlled Many people think an engine runs off of “explosions” of the air fuel mixture, and that’s incorrect, it’s actually when compared with piston speed actually quite a slow burn, however detonation is the explosion many think of. Some think that Diesels detonate as a normal operation, but excepting for initially starting, they don’t, the fuel burn in a Diesel is initiated the moment fuel becomes present, there is so much leftover heat from the combustion event that occurred fractions of a second ago that it ignites the fuel. But cold diesels will knock, and that knock is sometimes detonation of a partial fuel charge.

My Brother detonated an IO-520 in a Cessna 210 to death trying to keep up with me in a S2R-T65HG, Somehow he thought you got more power when you leaned one out, it took awhile as he called me on the radio saying it sounded like the landing gear were “thumping” the belly, and only one cylinder lost compression so there was no complete loss of power. I didn’t take the engine apart, it was exchanged for a zero time motor, but I’m sure at least one piston had a dime sized hole right it’s center

Pre-ignition is NOT the same, nor is it similar to detonation, but it can lead to detonation. ‘The difference is normal ignition whether it be pre or on time consists of an ignition source where a flame front proceeds at a set speed across the combustion chamber, ignition does not necessarily come from the electrical system, it can for instance be a hot piece of carbon etc. The speed at which the flame front proceeds is set, it’s why on engines that have a much wider RPM range that ignition timing is advanced with RPM due to the shorter period of time there is for the charge outreach peak pressure, and why set timing works well on aircraft engines, because we operate at a narrow RPM band. ‘Now where detonation differs is that there is no ignition source, the entire fuel / air charge goes off at once, there is no source that a flame front proceeds from, it’s an instantaneous ignition of the entire charge. ‘That’s why detonation is so destructive, it’s because there is a huge nearly instantaneous increase in pressure, well above any pressure you will get from an ignition source, and why it often blows holes in pistons, heat follows pressure, and or can cause detonation. Chicken or egg? ‘You certainly can get an NA engine into detonation, Fly full throttle at sea level and start leaning it out, it’s likely you may get detonation and or pre-ignition. ‘It’s what makes me nervous when I read the dissertations on how to run LOP where people are advised to simply increase Manifold pressure to recover any airspeed lost from being LOP, but aircraft haven’t been blowing up engines so it’s apparent that it works, but I suspect that in reality there just isn’t any throttle left to increase, most seeking efficiency go higher, and if your N/A above 6 or 7 thousand it’s likely your full throttle anyway.
