The 330 also benefited from years of safe operations and hundreds of thousands of cycles when the accident and incidents happened. It had demonstrated that the events were very infrequent. That was not the case for the MAX. The ADIRU fault was the result of a very unusual combination of sensor error...Jump to post

First, the OP link notes all Airbus in 2022. Second, while the link says new A319, are these factory new or new to Volotea?

I'm pretty sure they could forego F and replace it with a good, modern lie-flat business class on these routes.Jump to post
It depends on the hub they plan to use. No problem for the aircraft on PKX-JFK but I am not sure CAAC will grant it that route. There is a big problem for CAN-JFK; I am not sure how profitable the route will be after the payload hits in order to make it work. CAN-JFK-CAN would be absolutely impossi...Jump to post
You first said the range number is for public information only and then you use ACAPS “brochure” payload-range chart whenever in Airbus’ favor. I think it’s extremely biased.

I guess the impression of 'Boeing underpromises and overdelivers and vice-versa for Airbus' is not entirely untrue.

Based on released data sheets from the past Boeing assumes more weight per passenger & Airbus uses 95 kg (209 lb.)/pass. This type of issue is also why operators are saying the CS100/A220 series is getting better fuel burn. The spec sheet uses 225 lb./pass. Ah yes, the old 'Boeing underpromises...Jump to post
If we extrapolate from Delta's PVG-DTW and PEK-DTW data above, we can see a legitimate concern of A350 on LAX-SYD. I am not saying it is absolutely can't do it.

There is some data about SQ A359 performance on SFO-SIN. It took off at 274t (close to MTOW), and with full 253 passengers + bags, but without cargo.

This is much needed encouraging news for Boeing. Though it seems as if 787s might be used as 'sweeteners' for some operators that are affected by the MAX grounding (thinking GA, there might be others). Is there any chance that might push the breakeven a bit further to the right?Jump to post
And you'd be wrong. From the real world data I have access to, I can't see the 275t version not being able to carry 280 pax + bags on LAX-SYD, even accounting for headwinds and extra alternate/diversion fuel. Note that in this case, it would barely be able to carry any cargo. You said 275t version ...Jump to post
I am not disagreeing with Zeke. CX A359 has only 280 seats whereas DL has 306 seats. I am not saying DL A359 can't fly LAX-SYD if they decides to block seats. I said it can't with full passenger. And you'd be wrong. From the real world data I have access to, I can't see the 275t version not being a...Jump to post
It's alright I guess.
Not sure it's worth all the hullabaloo they created around it, but that's what marketing people do best nowadays...
Having both the 359 and 35K in similar configurations also allows for much greater flexibility on routes with variable or seasonal demand.
Subbing a 35K for a 359 or vice-versa can be done quite easily and at short notice.
The important point is to have MCAS not activate at low AoA. That's why high AoA vane signal failure rate is a more important concern. I disagree. Aircraft systems, especially those that directly impact the airplane's flight controls and trajectory, are meant to be fault tolerant, usually multiple-...Jump to post
Some more details: This was the DM-1 capsule which was recovered from the ocean after splashdown. They wanted to use it for the launch abort test.

Yes, the other 5 modes can bring the plane down if the pilots do not recognize "STAB Runaway" and apply the appropriate procedures. It's worth noting that none of these 5 are called out specifically in the 737 QRH. They are all covered under a single "STAB Runaway" procedure. Is...Jump to post

So the only diagnostics available is AoA disagreement? Oh, for chrissake. Then it really is a flying coffin. I sincerely hope that's not what they'll come up with.
