this is true, I was always a little paranoid though in the club 172 switching tanks, I always felt like that knob hadn't been touched in over 30 years since it rolled off the assembly line. I never did understand the uneven fuel burn in the 172.. I get that the vent design is different which can add dynamic pressure to one tank, however the tank vent lines are connected, at least on the 172N they were per the POH. I was crazy bored on a cross country flight a few years ago and flew the plane uncoordinated with a fairly strong slip to see if I could get the gas to slosh back.. (the things we do when we get bored)running off of both is fine and leaves switching to a particular tank for when you just want to balance out the fuel to keep the wings level (without aileron trim/input).

In early 172s there is a warning of the possibility of vapor lock if running above 5000DA and on both tanks. No idea why because I haven't dug into the fuel system setup, but it's in the POH to run on 1 tank above 5k.

the procedure on our club 172s is to turn the selector to the left tank every time we park, so our selector gets used twice on every flight. Moving from Left to Both during preflight, and moving from both to Left during postflight/securing the airplane.You're probably right to be a bit concerned. The fuel selectors in the 172 always seem to be pretty stiff and squeak a bit when turned, lol.
Isn't that the point of the show "Undercover Boss?"You would know this how, exactly?
I flew with my recently licensed nephew recently, great flight btw, down somewhere in FL, and they had the same policy. Looked like their planes were 172R. It did make me feel better tbh. Someone also said that it helps when the fueling truck fills the tanks, otherwise one tank feeds the other when fueling and it can be hard to really top them both off (no idea if that's true, but from the fueling diagram it seems plausible)the procedure on our club 172s is to turn the selector to the left tank every time we park, so our selector gets used twice on every flight.

..cool, so it is true then if a fuel truck dude is filling up a 172 with tanks on both some of the gas is crossfilling into the other tank. That's another paranoi, if for some reason one tank gets contaminated (not necessarily from fuel truck, but some other reason.. I once had a guy accidentally poor 3 gallons of TKS into a fuel tank) then you've basically screwed yourselfThe real reason is to keep fuel from venting overboard if parked on a slope with one wing down

Which is not necessarily wrong either if your goal is to sell more and you are new to a company or field. When our new CTO started (and yes, the guy actually knows dev technicalities with a degree from MIT, so not totally apples:apples) but he spent his initial time here looking at our products from the eyes of the user, and asking what seemed like sort of "dumb" or obvious questions to people within the company, but honestly were the kind of questions that people new to the products may haveHe's asking questions a customer might ask.
Also, with a huge backlog on the Cirrus jet I hope they don't go the way of Cessna and 20 years from now will only be catering to the turbine crowd

let's wait and see before assuming the worst, although the pessimist in me tends to agree with you.. so far I think they have a pretty good product line up from entry to higher end. Piper and Diamond were able to maintain their piston focus and hopefully Cirrus will do the same.. granted, both Piper and Diamond failed to launch a jet offering for their lineup however Piper has not let their turbine offerings lead them astray from piston.. so I'm cautiously optimisticOh they will, and in much less than 20 years time. The recession would have hit hard by then. Writing's on the wall for certified piston. Only the 'antiquers', or those for whom OPP and labor costs are free, will be able to endure.
but SOME people don't use their checklists....Cessna Pilot’s Assn has a library of crap on how to get them to even out. You can drive yourself mad trying to do it.
As far as the valve never being moved, that’s one of the reasons the POH specifically says to move the valve to left or right in the shutdown checklist. The real reason is to keep fuel from venting overboard if parked on a slope with one wing down...

I guess because the FAA wouldn't like us sitting right on top of a fuel tank? I can't imagine it would need to be much more than a gallon though.
Added weight, more failure modes, and the tank almost certainly has to be somewhere in the fuselage, which is the last place one should want any quantity of fuel.
Even the header tanks in a Cub give me pause.
So was there an "all" option or did you have to pick between L, C, and R?The early wood wing Mooney M20's had a center fuselage tank under the rear seats.

“You have to move that fuel selector from one tank to another? Why doesn’t that just happen?” he wondered. And setting up the radios before a flight, making those calls. “Why is that not a text message?”

No brainier. I've wondered why this isn't on most low wing aircraft for years.
yeah you know meeee!You down with OPP?

Just a few weeks into his new role, Nielsen (whose first name is pronounced like “Shawn”) began flight training the week before EAA Airventure. During a brief discussion with AOPA at the show in Oshkosh, Wisconsin, he noted that numerous things about modern airplanes still perplex him. “You have to move that fuel selector from one tank to another? Why doesn’t that just happen?” he wondered. And setting up the radios before a flight, making those calls. “Why is that not a text message?”

Sure seems like a three position (maybe four position with "off") selector valve was used, there are no cross feed lines. I could not see the actual valve, it must be in a box with some other interior stuff. If I get a chance I'll try to confirm if the old part number is available somewhere.^or did you just go off the center tank and assume L and R would drain into it?
For what it's worth it's not all marketing buzz.. if it were then since 2001 people would have caught on to it and they wouldn't have made it this far (see the whole Juicero thing for example). Granted, I 100% agree with you that they're not just selling a plane, they're selling a brand and a lifestyle, in much the same way that Apple does (for better or worse)..."“We need more people,” he said of the pilot community. “Every day what we do is to try to create pilots. If we have the best product, they will fly with us.” The Cirrus Lifestyle campaign has shown how learning to fly can change peoples’ lives. “The new currency is time,” said the new CEO. A GA airplane allows people to get more out of life and do things that others can’t do."... I'm not so sure he's using the word when he says "create 'pilots' "
I'd be happy if someone came up with fuel quantity indicators for my Piper that are as accurate as the ones in my pickup trucks.
They did and I have them in my Piper.

Yep, that's quite the chore but well worth it. I recommend getting someone to help you so you aren't climbing in and out of the plane after every two gallons in addition to pouring fuel and filling the tank.
