Thank you very much Doc Lightning, that's an awesome explanation, but did you mean non-planar here? ...A planar wingtip device does not increase the bending moment as much (but it still does) and does not increase the span as much (but it still does) but it needs to be about 50% bigger to achieve t...Jump to post

Looks like DL 2353, a 767-300ER (N1608, delivered in 2000) rapidly descended from FL390 to FL100 over a course of about five minutes and diverted to TPA from a planned ATL-FLL. https://www.flightradar24.com/data/flights/dl2353
Has anyone heard about this? Looks like a depressurization event.
What is the difference bewteen a planar wingtip and simply increasing the span? The rake affects the wingtip vortex differently. So here's the deal with raked tips: A simple span extension becomes an unacceptable design because the leading edge needs leading edge devices. That far out, the wing bec...Jump to post
Hopefully not, that livery is timeless it feels like. So was Landor. BA has always done a great job with liveries for its time. But their visual brand is very distinct.

Actually, it's not so much maximizing additional lift but reducing induced drag (a function of lift). Induced drag is reduced by artificially increasing aspect ratio. Both planar and nonplanar wingtip devices increase lift on the outboard span. A planar wingtip device, like the Boeing raked wingtip...Jump to post

I suppose you could remove the wings, fit 737NG wings instead with 737NG engine mountings and engines CFM is not planning on producing the CFM56-7b much longer because it will be replaced by the LEAP-1B. Also, this aircraft would be utterly uncompetitive against the A320NEO and no amount of financi...Jump to post
1) The airplane is longer for the same number of passengers because of the 2+3 seating arrangement. 2) It is both structurally and aerodynamically more favorable to have the engines mounted on the wings. This both softens the sudden increase in overall cross-section at the wing root by starting it w...Jump to post
Dunno if Boeing have a good cupholder or not either - if so they probably have a buzzword acronym for it
From what I can see, the A330 cup holder is a slightly tapered tube sticking out of a vertical surface and it seems to be placed in an unergonomic place. By contrast, the 777 cup holder is a sophisticated design that can hold a regular paper coffee cup, a coffee cup with a handle, or a soda can all ...Jump to post

Also BLADE only works when one holds extremely high manufacturing tolerances, which adds a lot of cost to build and maintain so you'd only use it when it paid for itself.

If you do a news search of ultrafan "variable pitch" in DuckDuckGo, the most recent hit from a standard aviation media website is from 5 years ago, so I think it's safe to assume that variable pitch won't be a feature.

In addition to what GalaxyFlyer said, the benefits of these devices are relatively modest, in the range of 5%.

What always puzzled me is that on the 777 and 787, the inboard ailerons droop way down as thrust is applied at take off. As the plane goes down the runway, they go up, almost too high, then further down the runway, they droop back to whatever flap setting is selected. On the 777 and 787, hydraulics...Jump to post
From what I've gathered, Boeing also offered UA massive discounts on the 773ER as well.

The frames were not changed despite the external differences between them and prior 777s. You could argue it either way.

UA has a diverse fleet of 777s. The L-UA fleet features PW 772A and 772ER fleets, while the L-CO fleet consists of GE 772ER frames. The postmerger fleet also features 777-300ERs.
So now that the merger is in the past, are pilots flying L-UA and L-CO aircraft? Are they also flying 77Ws?
