Except for a few one offs here and upgrades of existing engines that use same pylon/engineering those planes were built with the final engines from the factory. This is not true. There were around 1000 747s that had their pylons upgraded over the years, some because of increased thrust (the 747-100...Jump to post

Based on your experience, what do you expect Airbus to do in terms of parts support if everyone retires the A380, and only Emirates decides to re-engine all their 120 A380s to keep them flying for another 10-15 years? Would Airbus even be interested in providing substantial support for that long? I...Jump to post
Many of the A380 models have never reached their FIRST overhaul period.. they might first have to ascertain what the weight and Thrust load on the wings is to even allow new engines to be hung on it. the airframe might not even make a difference if all the rest is OK from the wing box outwards but ...Jump to post
Replacing engines with upgraded versions of the same engine is generally not considered “re-engining”. From an engineering and certification standpoint it’s not even close. I have to disagree, it required the TCDS to be amended after the certification process for each engine variant while keeping t...Jump to post
What’s the thinking behind closing the centre runway? Forgive not overly clear on the technical components I understand making it longer as well as new taxiway exits for traffic to serve the runway to/from the north/south side of the runway. This will also involve a lot of drainage work, and cablin...Jump to post
New engines on existing A380s, that aren't even that old yet, wouldn't be cheap. Nothing needs to be done in the short term, more like 6-8 years away. By that stage I would expect around a 10% TSFC improvement over todays best 70 klb sized engine. By that stage the Trent 900 would have been flying ...Jump to post

Someone is regretting not opening their wallet a bit more when Airbus and RR were offering the 380neo.

In the case of the Qatar A350 issue, they could accept the Airbus offer to remediate the aircraft, but are concerned there is a defect that will only surface again, or in other aircraft.

So Zeke, this debate comes down to your having already ruled on this case, whereas I am describing the positions of both sides.

The court does not agree with any of what you are saying. The cause does not need to be known for the aircraft to returned to service, that is a delaying tactic and doing the exact opposite of what the court put in its judgement. The court wanted progress and ordered QR and Airbus to consult with th...Jump to post
If I'm not mistaken, the A350 also tries automatic engine relights and such. Do you know more? Interesting to learn what A thinks they can handle by pre-defined code and what they shy away from. Is B more conservative with respect to automation/AP scope/computer flying? The 787 was the latest clean...Jump to post
Well, the 777X has been "launched." No, it is not in service, but it certainly is launched. KE and OZ both have lots of experience with the 777. Same could be said for SQ, they had significant 777 experience. The elephant in the room and the reason why Korean buys so much Boeing is they m...Jump to post
Both he and you object to Qatar's position, which means you have already decided it's wrong. I don’t object to all of QRs positions, if they feel they will encounter higher life cycle costs that is a legitimate complaint. I do object to the notion that the aircraft could not be returned to service ...Jump to post
You seem offended by the opinion of the court, mind you they did order QR pay 95% of Airbus costs. The court does not care what QR feels or believes, it wants the dispute resolved, and have handed down an order on what it expects. Can you cite a case where a litigant has disregarded what the court h...Jump to post
QR can write whatever they like in a press release, they can invite everyone to take photos and videos.
It means nothing to the court except a blatant demonstration of contempt towards the order handed down in a case they brought before the court.
If QR keep this up I see the case being dismissed..
Zeke....how many CX 350's have suffered paint defects and how was it resolved ? Just an in-house repaint ? Quite a few, however it was a different mechanism, it was paint peel. Paint peel is when the aerodynamic exposure just lifts the paint from the surface, I saw this mostly starting from the fro...Jump to post
Qatar is not satisfied with the root cause determination provided by Airbus.

So in other words…Airbus did not provide your airline an aircraft with equipment that does not meet regulatory requirements aboard and my statement still stands. Absence of fittings is not the same as having non certified equipment on board. OEMs will gladly provide an empty aircraft if the custome...Jump to post
Airbus will want proof of certification before they hand it over to a customer.

So Airbus violated their own "in service tolerance levels" by applying paint too thickly at the airlines' request? The livery and type of paint used is a customer option. It is like saying why would Airbus ever agree non standard cabin modifications, because the customer requested it and ...Jump to post
I doubt that the QC department at Airbus would let the plane out the paint shop, regardless of the customer's willingness to accept it as is. It would violate many aspects of ISO standards. Excessive thickness does not mean you exceed the spec. It means you didnt meet the spec; you failed. Is there...Jump to post

This would be a slap in the face after the 2 CEOs had just met for the IATA AGM.

Why flight data is available to IFE at all? Apparently, when 737 systems were designed, IFE wasn't a real thing.

If my memory serves me right, flight control story was about 757 or 767. At least the story I have in mind was about a newer generation one.

That is a good tough question. Of course, I have no rock solid answer for you - such things are generally not becoming public until there is gross problem, like it happened with MCAS.

I think the IFE gets GPS information only. When we fly on standard QNH it will seem a bit off that the IFE altitude is displaying something like 36143 feet.

I think the key to this is understanding which aircraft use a hydraulic to fuel heat exchanger.
I have used many external hydraulic kidneys especially on earthmoving equipment to drive the hydraulic system, we had a couple of inline filters to clean the metal out of the system.
