It's a little misleading as it looks like your tilting the rotor disk, but all your are doing with the swash plate is changing the pitch on the blade. He explains it a little better in the longer video here: https://www.youtube.com/watch?v=-8QzYicgTL8&t=192s The up/down (flapping) movement comes from 90 degrees after the change of pitch due to phase lag. So, to make the disc tilt forward you decrease the pitch on the advancing blade and increase pitch on the retreating blade. (at 90 degrees to the direction of travel).

In what's sure to be "a real bummer" for Boeing's public relations people, a 757 had to divert due to "wings fall off syndrome" https://avherald.com/h?article=51530e9d&opt=0

Yeah, that very very much looks like impact damage, also the last 757 rolled off the production line like 20 years ago, I think Boeing's in the clear on this one.

Poking around the internet for more info on that 757 slat delamination, I found this article that claims United can't fly their A321NEOs that are supposed to replace their haggard-rear end 757s, because they can't turn the no smoking signs off. E: and they say Boeing has quality problems 🙄

I was on a flight not long ago where the no smoking light had been replaced by a non illuminated, painted sign or decal. Pretty sure it was a domestic us flight, American or United I forget Are they required to be lit up

Theris posted:Ok, fine. Everyone please pretend I said "jet" instead of "aircraft." Thanks. if you use the current usage of "jet", the tu114 still qualifies. if you use the older usage of jet, then the rockets qualify! (i think the rockets still fail the "airliners" part because even the commercial ones are still essentially charters, not regular scheduled service)

Beef Of Ages posted:And switchable, apparently. Apparently the FAA granted the waiver within a couple hours and the planes were back in the air. It's one of those old regulations that was perfectly logical when it was written. Back in the day when smoking was allowed of course you want the crew to be able to signal that smoking is or is not OK depending on the situation. Now it sounds stupid but like many old laws on the books, no one has been bothered to get around to changing it. If this was just some city ordinance, people wouldn't care and cops wouldn't enforce it. But because this is aviation and the subject is an aircraft worth a hundred million dollars, every little rule has to be followed or the lawyers and insurance agents will have your rear end. Of course the FAA understands and is quick to grant waivers... as long as you remember to apply when you buy a new model.

Cactus Ghost posted:if you use the current usage of "jet", the tu114 still qualifies. if you use the older usage of jet, then the rockets qualify! Goddamnit I even thought about throwing in "and I mean the colloquial usage of 'jet,' not BLADE's 'technically a turboprop is a kind of jet even if literally no one actually uses the word that way in practice' or the source of JPL's name" but didn't think I'd actually need to. And really the contention with the rockets is that their operators would probably not care for you calling them aircraft rather than spacecraft. Either way, i promise I like waffles. Please don't put in the newspaper that I hate waffles. Edit: You know what? The 108db always quoted for the Tu-114 is from right next to the engines inside a cabin with Soviet noise isolation. (ie, none) The source for the claim for the civilian Conways is 116db measured under the flight path of the plane at a point 21,000ft from the start of the t/o roll. I bet the Conway 707/DC-8s were just straight up louder anyway even if the cabin was certainly much quieter. Edit 2: The same source has the Tu-144 Concordski at 110db for the 21,000ft from the t/o start measurement. It does beat the Conway 707 with 114db 450m laterally from the runway centerline vs the 707's 112db. However, it also has a variant of the Convair 880 at 117db for the under the t/o path measurement, and a JT3D-7 powered 707 at 120db under the approach path vs 112db for the Conway, so  It's here if anyone is interested.

This 757 talk reminds me that there's still a corner of my mind which has never gotten over my childhood disappointment that a 757 is smaller than a 747. Number go up should mean plane bigger. This is solid child logic.

I watched Ernest Saves Christmas this past year, and the opening shows the real Santa Claus's flight landing as a DC9 and taxiing to the gate as an L-1011. I never flew on a L-1011 and I went down a rabbit hole to see if there were any in a museum. Turns out there is still one flying. https://en.m.wikipedia.org/wiki/Stargazer_(aircraft) Pretty cool.

The 7E7 (terrible name)/797 was meant to be a 757 replacement before they went long (literally) on the 737.

If an ashtray breaks, that lavatory is off-limits. If the ashtray is missing entirely, the plane is grounded. Someone please correct me if the MMEL for some type has finally gotten adjusted or a waiver has been granted for: 14CFR25.853(g) posted:Regardless of whether smoking is allowed in any other part of the airplane, lavatories must have self-contained, removable ashtrays located conspicuously on or near the entry side of each lavatory door, except that one ashtray may serve more than one lavatory door if the ashtray can be seen readily from the cabin side of each lavatory served.
