Chissà cosa hanno modificato.

Onemileatatime.comAirbus is making big improvements to this plane without even technically relaunching it.*Airbus has*announced*that the A220 will be offering increased range starting in the second half of 2020.
Essentially Airbus is able to increase the maximum takeoff weight (MTOW) of the A220 by 2,268kg.*This is being achieved by taking advantage of existing structural and systems margins, and increasing existing fuel volume capacity.
With this change:
The A220-100 will have a maximum range of 3,400nmThe A220-300 will have a maximum range of 3,350nm
For both the A220-100 and A220-300, the maximum range of the plane is being increased by about 450nm.
Sei della DIGOS?Estremamente interessante, per quanto , a mio avviso, relativamente applicabile nel mercato europeo. Piuttosto, la mia curiosità adesso verte su un’altra domanda: sei sempre stato (a torto o a ragione) ipercritico nei confronti del CS Series, che la storia ci dice avere affossato Bombardier, costretta dai numeri a cedere il programma ad Airbus per non chiudere la baracca. Ora, la domanda è: alla luce delle considerazioni riportate nell’articolo, hai qualche ripensamento?
Altra domanda: la risposta di Embraer/Boeing con il 190E2 sarà all’altezza?
Ultimo quesito: è in corso una traslazione del mercato Regional verso l’assimilazione del corto raggio, con una netta demarcazione tra Regional/Corto (A220/E190E2), MR (dai 32XNeo e B 73Max), LR (B 77/78, A35)?
A naso direi in sostituzione di E190, A318 e A319.È stato ufficializzato l'ordine per gli A220 da parte di AF: 60 ordini fermi, 30 opzionali ed inoltre 20 diritti di acquisto futuri (che non so cosa voglia dire, sto traducendo dalla stampa locale "en droit d'acquisition").
Ho letto anch’io che sarebbe in ballo un ordine o per A220 o per E-Jet E2. Il problema dell’A220 è quello dell’apertura alare, che di fatto a LCY impone l’uso solo di determinate piazzole. Anche a pieno regime, dopo l’espansione del piazzale in programma, non credo ce ne saranno in numero sufficiente per ospitare un’intera flotta di A220 nelle “ore di punta”.Ho lento tempo fa che IAG sarebbe intenzionata a prendere una trentina di macchine per CityFlyer e secondo me anche lì potrebbe caderci il 220.
Mi dicevano anche LX avesse portato un suo 220 a AY a far vedere, poi boh.Bel colpo per Airbus.

Second Swiss A220 suffers similar engine rotor failure
Investigators are probing another serious engine failure on a Swiss Airbus A220-300, less than two months after a previous similar incident involving a sister aircraft on the same route.
The aircraft (HB-JCA) had been operating Geneva-London Heathrow on 16 September when the failure occurred in the left-hand Pratt & Whitney PW1500G engine during climb.
US National Transportation Safety Board investigators state that the incident took place just before the twinjet reached its cruising altitude of 35,000ft.
The crew returned to Geneva after carrying out quick-reference handbook procedures and declaring an emergency.
Inspection of the aircraft after it landed showed that the stage-one rotor in the low-pressure compressor had separated and there was a hole in the compressor case.
None of the 77 occupants was injured.
French investigators were already looking into the failure of the left-hand PW1500G on another Swiss A220-300, under similar circumstances, on 25 July.
The aircraft (HB-JCM) had departed Geneva for Heathrow and had been climbing through 32,000ft when the failure occurred.
Investigation authority BEA subsequently sought public assistance to find engine components which they believe were shed from the aircraft over France. The stage-one rotor of the low-pressure compressor was found to be missing after the jet diverted to Paris.
The aircraft involved in the latest incident was delivered to Swiss in May 2017. It had been operating the LX358 service while the earlier event occurred to flight LX348.
Investigation of both incidents has been delegated to the US NTSB.

Swiss A220 engine failures prompt rotor inspection order
Operators of Airbus A220s are being instructed to conduct checks of the low-pressure compressor on Pratt & Whitney PW1500G engines, following two similar incidents involving failures on Swiss aircraft.
The incidents – on 25 July and 16 September – both occurred to Swiss A220-300s operating the Geneva-London Heathrow route.
Operators of the type have been told in a US FAA directive to perform initial and repetitive inspections of the compressor's inlet guide vane and the stage-one rotor.
Both Swiss A220 incidents involved failure of the stage-one rotor, resulting in the rotor being released from the low-pressure compressor case and damaging the engine.
"[Such] rotor failures historically have released high-energy debris that has resulted in damage to engines and [aircraft]," says the FAA directive.
It adds that, owing to similarity of design, it is extending the inspection regime to Embraer E2-family jets fitted with Pratt & Whitney PW1900G powerplants, because they are susceptible to the same condition.
The directive covers engines which have accumulated fewer than 300 cycles.
Initial inspections must take place within 50 cycles and within each subsequent interval of 50 cycles until the engine reaches this 300-cycle threshold.
They require borescope inspection of the rotor for damage or cracks at the blade tips, leading edge, and other areas, and checks on the inlet guide vane stem for misalignment. Any substantial findings must prompt replacement of the low-pressure compressor.
Pratt & Whitney issued a service bulletin on 23 September covering the borescope procedures. The FAA says the directive, which takes effect immediately, is an interim measure because the investigation into the Swiss A220 engine failures is still continuing. Cirium/FG
