I bet at L/D max and the minimum power to hold altitude, LOP of course, you could keep a Mooney in the air for 10 hours or more. If you could stay airborne on 3 GPH those long range airplanes could make 30 hours! Assuming factory tanks. Not these ocean crossing long range things. Quote

Found the link to Jonathan Paul's flight in his E. He had long range tanks, 90 gal total, no ferry tank installed. it's a great read! I'm reading it again . . .

His IO360 and prop combo is the same as yours, but he has a less draggy airframe. A good read here http://www.jonathanpaul.org/pdf/NonStop.pdf Anyone up to beat his record???? Quote

A64Pilot Posted March 24, 2021 Report Posted March 24, 2021 I’ve sat in a single seat airplane with no autopilot for over 14 hours before, it’s no fun. Ferrying crop Dusters they held 228 gls in the wings and we also turned the chemical hopper into a ferry tank. that added another 510 gls, so 738 gls. At altitude fuel burn is about 40 gls an hour so that’s 18 hours of fuel. ‘I never did it, but many have been Ferried to Australia, the longest leg was from California to Hawaii, Drop tanks were installed for that giving well over 24 hours of fuel on board. The tanks were not droppable 1 Quote

A64Pilot Posted March 24, 2021 Report Posted March 24, 2021 This one takes the cake, not as a MPG or whatever, but can you imagine? My understand that a large reason the quit was the poor engine couldn’t make enough power to keep flying one they refueled, so they were having it refuel more often and finally just quit. https://www.aopa.org/news-and-media/all-news/2008/march/01/endurance-test-circa-1958 1 Quote

You spend every minute of over TWO MONTHS with one other person inside a 172 and get back to me! Frankly, that is the aviation record to end all others. It's over 60 years old and I don't think it will ever be broken. No one alive today is that motivated (or crazy) It's been years since I saw it hanging at McCarran....anyone know if it's still there? 3 Quote

A64Pilot Posted March 25, 2021 Report Posted March 25, 2021 (edited) What impresses me most about the record is it’s wasn’t accomplished by someone who wrote large checks to have something no one else could afford built to set the record. It was two plain ordinary pilots with a plane Jane off the shelf airplane, doing things that probably would not be allowed now Edited March 25, 2021 by A64Pilot 2 Quote

I think it was as much as anything that the engine was developing so little power it was becoming difficult to fly. that and of course they were about to lose sanity and a I’d guess plotting how to kill each other. At that weight it’s likely even with a healthy motor it was a dog That motor had 2000 hours on it with nothing but oil changes, no plug changes, and nothing done to the mags, no timing check etc. Edited March 25, 2021 by A64Pilot 1 Quote

But as for sanity - I would guess that after 1 week they would be stark raving mad ready to land and kill each other - more so after 1 month, that after 2 months I ask - why now? Of course they would need to be stark raving mad to even think to try such a thing in the first place. In a 172 no less. At least they could have chosen a 182 for a bit more shoulder room! Quote

A64Pilot Posted March 25, 2021 Report Posted March 25, 2021 I think unleaded gas would really have made the difference, I look forward to the day that hopefully we will be offered 94UL, so long as they don’t jack the price up for leaving something out. Unleaded fuel ought to pretty much eliminate plug fouling, and allow us to move into the 21st century oil wise. ‘Of course a few need 100, but most don’t. Quote

Right - unleaded fuel (on a Cessna 172 at low altitude like that - modern auto-fuel would have run that O320 just fine), fine wire plugs, and electronic ignition. They could have gone for 6 months!

A64Pilot Posted March 25, 2021 Report Posted March 25, 2021 I’m not abdicating eliminating 100 LL. however it’s no secret that the Friends of the Earth and a few others are. ‘I believe making 94UL widely available and at a slightly cheaper price to give some incentive, would significantly reduce the amount of leaded ful eluded and may buy us more time. ‘I actually though long and hard against buying a high compression fuel injected engine, but decided that the sky has been falling for over 40 years and hasn’t yet so go ahead.

In a 172. in 1958 Mogas wasn’t unleaded, well most wasn’t, Amaco sold a “white gas” that was, but maybe that came later? Mogas to quote Avweb is a “non starter” and I intend to agree largely due to it not doing so well in storage. ‘I assume they likely ran 80 Octane and maybe that’s why the plugs lasted so long? https://www.avweb.com/insider/going-to-the-moon-was-easy-compared-to-100ul/ Edited March 25, 2021 by A64Pilot Quote
