The main problem would be the lack of runway length though. B737-800 already have problems land there, let alone the A321XLR. an unconnected statement. ISA MSL data: The XLR will have about the same MLW that the regular A321 sports ~79..80t for ISA and sealevel that is 1780m landing field length. T...

Re: 10 Years Since Fukushima Earthquake and Nuclear Disaster

This may not be true of next generation plants. Another odd problem is nuclear plants have come in essential...

Re: Airbus A350-900s to remain exclusively Trent-powered until at least 2030

Hopefully these problems do not surface on the XWB. The downside to a single engine option is that if that engine craps out, you're in trouble. Engine maker swaps on existing frames are uncharted territory. nobody does it. ( except in PR or for some single item. afair just one A380 was "gender...

Re: Airbus A350-900s to remain exclusively Trent-powered until at least 2030

I am amazed at how people seem to think that engine manufacturers can keep up the previous pace of development. To me each incremental move forward becomes more and more difficult and expensive to develop test and implement. Plus each will potentially have flaws that do not emerge until well into s...

Re: NASA Super Guppy Replacement?

Considering the Beluga has a cargo hold width of 23’ 4”, it might have a problem with a 25’ wide load. Weight is also a factor, we’d carry 250,000 pound loads all the time, as does the 124. Space structures are sparse. And they are never transported fueled up. They could order a new Beluga XL(D=29 ...

Re: 10 Years Since Fukushima Earthquake and Nuclear Disaster

Right, but that only applies to nuclear facilities built in areas that are less than suitable. Japan obviously does not have much of a choice where to build their facilities given their geography, but the vast majority of plants are not built in tsunami zones. It seems the real issue here is the fa...

It would be back to the future in another way too.

Anti Trust legislation might put a stop there: Junkers was broken up ( planes, engines, airline ) ...

Re: A350F. Airbus looking to launch: Looking for customers

With folding wings soon to be a thing on the 777X and Airbus recently patenting their design, it will be interesting to see if there is a larger future freighter that can fold down to fit in a code D gate. Anything new and significantly different from the existing one? The one I know about is from ...

Re: A350F. Airbus looking to launch: Looking for customers

We don’t know the final capabilities of the 778F. As has been eluded it seems the MTOW bump will make a significant difference You see an upcoming MTOW bump for the 777X subfamily? IMU 353t looks like a rather hard limit. no other airframe seems to have higher runway loading than the 777 @ 353t MTOW.

Well Airbus spent billions more on the A350 program and needs to recuperate it.
