Re: Does a 737 Max 10 really need MCAS?

Why not certify the -10 as an independent type from the -8/9 and get over all the trouble at the cost of a different pilot pool. Because then they have to start over as if clean sheet and lots of things that get grandfathered from the original 737 type certificate no longer get grandfathered. The p...

They haven't flown it yet. All they have is modeling and simulation results to tell them one way or the other. The nacelles, presumably, have the same aero characteristics as they do on the Max8 and Max9, so, presumably, generate the same lift component at the same offset from CG at the same AoAs an...

Re: Sources: United ordering 50 A321 XLR

Could we see the XLR on DEN-HNL in addition to EWR and IAD TATL? DEN-LIH and -KOA seems more likely since DEN-HNL and DEN-OGG are already using 772 vs DEN-LIH and -KOA which are using the 752.
