Re: Air China to reduce Shanghai Pudong-San Jose frequency

As someone who lives halfway between SFO and SJC, I use both airports. It would be great if SJC had more international flights but I can see why it struggles relative to SFO. Unless you live south of the Dumbarton Bridge (Menlo Park on the peninsula, or Fremont in the East Bay), SFO will be as conve...

Re: Boeing 797 Discussion Thread - 2018

Hell I bet lots of airlines if asked would say they would rather Boeing and Airbus build lighter and shorter ranged narrowbody aircraft. I think that’s the biggest C-Series missed opportunity. It should have been six wide and have a range around 2,500 NMI so it could be lighter per passenger. I act...

Re: 737 MAX 8 fuel burn meeting expectations

Re: Boeing officially launches 737 MAX 10

I thought the main gear on the 737NG and MAX7/8/9 were already as high as possible without requiring slides for the overwing emergency exits. I deduce from this that Boeing was not actually right up to the height limit earlier, but most likely is now.

Ah, sorry looked for a post and didn't see it. Not surprised it was you though.

Now if only airliners.net could fix their timestamps; it seems "moments ago" means anything from seconds to hours. This degree of imprecision seems rather out of place on a site about airplanes.

Re: 787 Production/Delivery Thread - Part 43

The -10 just makes the A350's proportions confusing to me a even more. The -10 is just 2m longer than the A359, and 5m shorter than the -1000, yet it looks waaaay longer than either. I think that's because the 787 is narrower and sits lower on the ground, so if you drew a box to fit the -10 fuselag...

Shades of LH, just replace gray "underwater" section and the blue tail background with black. I think AC is trying to go more Euro. The dark belly is a traditional design and responsible for what others have called a retro feel. I don't think dark bellies are really retro, just traditional...

Re: 747-8i window seats in last four rows of Economy

The space to the wall is large in the first row, and smaller as you go back, but even in the last row, I believe it's larger than normal. This does have the disadvantage of not being able to lean on the wall when you sleep. However it has the advantage of giving you yet more space to put stuff. The ...

I stand corrected, so apparently the dorsal fin is there only to increase the critical angle. That is consistent with this history of the 307: https://en.wikipedia.org/wiki/Boeing_307_Stratoliner

Re: 737 Tail

I've often wondered why every 737 needs the dorsal fin (the anterior extension) and the a319/320/321 don't, and look better for it. As others have noted, at least the longer 737 variants such as the -9 should be able to do without, given that longer planes produce larger moment arms and thus make th...
