What EU laws exactly requires Airbus to produce aircraft quieter than Boeing does?

Have you ever wondered why FRA has a curfew??? Quiter aircraft can help lift those.

Yes many airports have curfews for noise abatement.

There is no EU law that requires Airbus to produce quieter aircraft. The laws around noise abatement and noise levels for aircraft apply equally to Airbus and Boeing aircraft.

Well in effect they are since EU and national courts are handing down judgements regarding the amount of noise being tollerated. It is a round about way. However if airlines cannot fly to certain important destinations with certain models because they do not conform - aircraft builders are more or less forced to come up with a solution or they will not sell their product.

It is a fact that europeans in particular the german courts are very pro indiviual rather than pro industry in this particular instance so airbus (bear in mind german interessts are fairly important here) is going about looking for solutions that will more than likely become an increasing factor in other countires around the world too.

Right now the aircraft builders are being given homework for the future by the airlines who in turn are facing the same development at many airports around the world.

Yes, however there is no EU law requiring Airbus to produce quieter aircraft. This was your original statement:

Airbus, Boeing and engine manufacturers are producing quieter aircraft/engines.

i am one of those who foolishly live "close to the airport"(flight path) however, i did not live "close to the airport" until bigger and larger planes were allowed, and a larger radius of service was allowed(DCA). although europe has "less space", most airports are quite far from heavily populated areas......lhr, cdg, mxp, fco, fra, muc, are all out in nowhere. most of the midsize airports in europe i have used are also out in nowhere.

when i moved into my current house, dca had only prop planes, and the flight path ended about 2 miles past the end of the runway. the flight path is now 15 miles out. dca had a 10 pm firm curfew. it is now a 24 hr airport with a pretty big dump shortly after 12 midnite.

the new jet engines are much quieter than the prior generations, not from decree"you be quiet" but from engine design. the engines now move a lot more air at lower velocity than the older generation engines. much quieter engines.

Have you worked out if they're a troll or not yet? I haven't. I need to see more samples of the writing. I have great hopes for them.

The A350 is using large sections of panels to create sections of the airplane like this:

THe B787 uses what they call "one-piece frames" which are somewhat larger sections than the A350's and have a full barrel to most of them. Picture explains this better:

Just imagine a bunch of those bolted together to create the fuselage.

i imagine it is of boeing to replace tail section after fire...for secure........sure all area of both 787 an a350 will be advanced in future...because of mishaps....yes a quite plane is better always...still not understand why one way too control plane as joy stick of airbus

Akelkar, thanks for the photos, I'm surprised by how light the fuselage section in the illustration is.

I am in fact refering to people who currently build homes close to airports like FRA and then complain about airtraffic.It is people like them who moved there knowing full well where they were going but it was CHEAP!!! Once there they complain to no end and go to courts. Its these peopl ewho are the cause for the curfew at FRA for example or the fact that FRA PAYS for their soundproofing and air conditions AND they get a fee towards the energy they are going to use to run those aircons. All of this is obviously put on to the ticket pricing and I do not see that as fair since these people knew EXACTLY where they were moving or building homes
