The 322 was in one of our presentations or newsletter.



Btw, the current 321 breaking is awesome as is before you even consider brake fans

I think, you could, using the materials from the A350 for the wing box, wing, and landing gear, make the weight requirements to keep the single landing gear. This would require very little investment by Airbus to develop.

If you went with this airplane, and some additional A330s, you could dump the 767 and the 757. The MoM plane is not needed unless the cargo requirement is essential.

Door 2 needs to be moved forward a few feet... and you're exactly right about 321 braking. She gets it done always with plenty of room near max landing weight in DCA.

The issue with a single axle truck from a performance standpoint has nothing to do with landing. It’s a abort at V1 where it comes into play limiting takeoff performance.
Airlines that don’t need that performance much prefer a single axle truck for lower maintenance expenses. The other issue is load bearing. Due to the footprint AA’s 321’s are limited to 15 knots taxi speed at LGA. They were damaging the taxiways in turns.

They should get a bonus for helping with the reconstruction...

So Boeing would have too do a full blown development and Airbus can wait and see and then launch this?

Or just launch it.

I guess it's a good position to be in.

You speak so much about which you know so little...

The brakes on the 321 GO. Plain and simple.

You shouldn’t be doing more than 15 knots in the turns at LGA anyways... esp if WN is behind you. 😬 It’s not comfortable for the pax, seriously. 10 knots for 90 degree turns is supposed to be the speed through a 90 in all aircraft models at Delta.

They are limited to 15 knots on straight always and slower in turns. I believe it’s 5 knots. What does seem strange is I don’t believe Delta has the same restrictions.
A dual truck aircraft can have amazing abort performance. A Delta 757 departing SNA aborted after rotation past V1 and stopped on the runway. Not bad for 5700 feet!

Unless the wings fell off and it became a projectile, why would anyone in they're right mind abort past v1 in Orange County? Am I missing the facetiousness in this back and forth?

They hit a large flock of seagulls. One engine quit and the other engine was destroyed and would not have made it around the pattern. The nose wheel was off the ground when tha abort was initiated.
