Are any PIPs expected for RR's T-XWB 97 engines in the lead-up to actual 777X deliveries to airlines?
Jump to postThe initial request was around 80k and 90k thrust but airbus wanted the same engine just an engine management tweak to change the power output. GE and RR offered a solution on that basis. The power out put rose to 97k , GE bugged out as it didn’t want to design two engines. RR offered to hurry a de...
Jump to postThat is false - the 16G rule is in relation to the seats - it's nothing to do with the hull. the 16G rule is in relation to the seats the 737 by far can not meet that specification because the floor is way to weak because the floor is to weak the hull has less stability and breaks first before and ...
Jump to postThe kind of answer I was looking is some orientation in the kw needed, for the system to work. Probably is easier to estimate in the case of the 787, being a purely electrical system for the task (tens or hundreds of kw?), than in a conventional bleed air plane, but maybe some conversion based of th...

Jump to postWhy this and other fume events don't prompt a systematic analysis of the air quality inside ALL types of planes? Why not sampling several hundred of planes with monitors for recording of CO levels and putting some filters inside the ducts and then search them for unwanted volatile substances, every ...

Jump to postCould the undesirable lift effect of the MAX nacelles at high AOA be fully compensated by aerodinamic ad-ons or a slight redesign of the nacelles, so no MCAS needed?

I think it has not been posted in the thread, this Bloomberg article with some interesting views from former, non anonymous, Boeing engineers:

Don't know if already mentioned that maybe another problems contribute to the aircraft control issues: https://www.washingtonpost.com/world/africa/ethiopia-says-pilots-performed-boeings-recommendations-to-stop-doomed-aircraft-from-diving-urges-review-of-737-max-flight-control-system/2019/04/04/3a125...

Yet some of the big conspiracy guys are putting a little more effort than that in explaining their views: https://www.fzt.haw-hamburg.de/pers/Scholz/dglr/hh/text_2017_04_27_AircraftCabinAir.pdf Surely a waste of time, as t...

Jump to postSeeing the excellent provided graphs for the 787-9 and the A359 I fail to understand how the 787-10 is going to be a (substantially) more economical plane to operate than the second for the expected medium haul routes as it was previously reasoned
Jump to postI'm hesitating to put the link, but the Daily Mail site has a lot of photos of the crash site (and also of some of the victims with names, beware). Lots of fragments on the ground, but because the abundant snow, at least to me look as "rained" as opossed to scattered travelling with high h...
Jump to postSure, I've never purchased cheaper tickets than lately, but at least for intraeuropean flights, airlines have decided that everybody would prefer to save 10% of the cost of an economy fare (which I translate for the additional capacity of a 737/320 gained when going from rational pitch to 28-29”), a...
Jump to postHello everybody. First post here in Anet. As it has been suggested that the hypothetical A350-2000 would need a more powerful engine, could the GE9x be used for that purpose? Or maybe there are technical/contractual too big obstacles for that combination?
