Looking at what you wrote I'd bet it's rule n. which you can find here:

Current military incarnations of the flying wing are a compromise between fuel efficiency, the need for stealth, and the ability to carry large payloads.

Grandfathering came about to protect owners of earlier-build aircraft, ships and buildings having to retrospectively comply with new standards.

Yes because it might have required even more reinforcement of the fuselage to carry more fuel, at the moment it is heavier because of the stretch, but with same MTOW The 787-10 has the same fuel capacity as the 787-9. and usually never maxed out there. So, needs more MTOW for more fuel on top of pa...Jump to post

Do you have evidence to prove the 737NG cabin isn't certified to 14g standards? I'm genuinely curious as i haven't seen anything outside "anet facts" to suggest this was the case.

If you're talking about optimizing fuel economy only, the "perfect shape" is a "flying wing" a la the B2 bomber. Stealth craft tend to not shine in the "perfect aerodynamic shape" domain. :-) B2 takes MTOW * .5 for 10,000nm range ( no payload, unrefueled from Janes via...Jump to post
I would assume the lighter weight of the 737NG vs the 320 is due to the narrower fuselage, not grandfathering. What standards exactly were changed? MTOW difference is 79t vs 78t.

I'm not the biggest fan of a.net doctrine, but that is correct. The A332 was a popular shrink but probably because the A333 was underpowered with low MTOW at the time. A332 shrink was the perfect decision for Airbus at the time. ( At its best time the A332 strongly dominated A330 deliveries.) while...Jump to post
