    The real test will be when the all new planes come out.

    The MS-21/C-919 or the A30X/737RS?

    I cannot see the former threatening too much just yet, airlines won’t bet the house on the aftermarket support (or lack of). Even if the newcomers had a 5% sfc improvement, I think the airlines would be very reluctant…

    I would be very doubtful Boeing will scrap the MAX.

    I think they’d sooner accept the performance shortfall, pay the penalty on any current performance promises and have strong narrowbody cashflow for the next 10+ years. In this years air show season, I expect the MAX to wipe the floor with NEO for one reason and one reason alone – slot availability.

    The technologies aren’t really there yet for a new single-aisle replacement (except interim engines), it would take Boeing about 8-10 years to get one to market, so they’d:

    – Be giving NEO a ~6 year headstart.
    – Screwing over all MAX signatories and pushing other Boeing incumbent customers toward Airbus.
    – Effectively withdrawing from the mass narrowbody market between 2016 and 2024.
    – Only achieving an incremental upgrade over NEO, allowing Airbus to kill the 737RS dead with an A30X which can incorporate the revolutionary technologies (such as propfans). That would be quite ironic given the original prediction of the A320’s demise prior to launch!

    http://www.flightglobal.com/news/articles/boeing-nears-max-thrust-definition-372416/

    Identifying the thrust demand from the CFM International Leap-1B powerplants will confirm the type’s maximum take-off weight and range. Meanwhile, the airframer is dismissing rival Airbus’s focus on the Max’s smaller fan diameter compared with the A320neo.

    “Physics doesn’t work in Europe the way it does everywhere else,” says Boeing Commercial Airplanes vice-president of marketing Randy Tinseth.

    He says both airframers are designing thrust requirements around their largest re-engined aircraft – the A321neo and 737-9 – but says the Airbus twinjet needs 20% more thrust, and this allows the 737 to employ a smaller core and smaller fan. Tinseth adds that the A320’s empty weight per set is higher than the 737’s – by 5-10% across the family range – and the larger A320neo fan will simply add more weight to the aircraft.

    [rant]Aye Randy you clown.

    Of course, Boeing would never have installed a bigger fan if they could have to maximise the bypass ratio! Oh, wait a second… that is exactly what they wanted to do… they even rejigged the nose gear to fit a bigger fan in.

    So, in Randy’s little world Airbus having the choice of an even larger fan and scaling the core exactly as they need is a bad thing.

    I guess the finer details of things like propulsive efficiency, engine thermodynamic efficiencies and Lighthill’s acoustic analogy are completely lost on the powerpoint wizard?

    Grrr – I hate marketing bullsh!tters[/rant]

    Sorry folks… read that article and had to get it off my chest. I’ll probably run into another speech by the European clown Leahy in a bit and be back on.

    Why are the journos not pulling him (Tinseth) up on such obvious bull?!?

    Oh, I’d also like to see the reasoning for 20% more thrust. The wing loading is approx 11% more for an A321 when at MTOW and with a ‘clean’ wing (c.f. 737-900 at MTOW). Albeit it (A321) does carry slightly more people. Its a long way from 11% W/S to 20% more thrust.

    If so, that’s crazy. Fair wear & tear should have been allowed for.

    But the clowns making the mistakes are not fired for being idiots.

    And Airbus will at least put sharklets on A318 – but not new engines.

    They have announced it (with the numbers you are looking for):

    http://www.flightglobal.com/news/articles/a318-to-be-available-with-sharklets-from-2013-347719/

    However, I have the feeling that engineering resource will be diverted to more urgent programs and A318 might be left to rot.

    In the proposed defense budget the uSAF had to cut several “nice to have” things to keep the more important stuff funded.
    Remember, the USAF is not an airline…if they use a larger than necessary aircraft to get an urgent mission done, no big deal…they don’t have to worry about profit and loss.
    There is always more money..tax money…available. :rolleyes:

    They’d rather use more fuel and have higher flying costs for the few missions than spend a lot of money on a new airframe.

    Sorry JB, completely disagree.

    This is a turf war and nothing less. There should be USAF top brass and certain members of the US congress/senate up on charges for this.

    If I was the relative of any infantryman killed in action for reasons which could be traced back to inadequate supply, I would be seeking to bring criminal charges against the individuals within the USAF/congress/senate that were involved in this decision.

    How can the US public accept the following course of events:

    1. US Army request need for ‘last tactical mile’ transport back in 2005. Program called Future Cargo Aircraft.
    2. USAF want on board, so in 2006 program renamed Joint Cargo Aircraft and a common airframe is specified. The Army were to lead the joint program office.
    3. In 2007, moves were afoot to bring the whole fleet under the control of the USAF.
    4. In early 2008, USAF reports emerge saying they will have little actual use for the JCA.
    5. In late 2008, the US Army are no longer going to receive the JCA and the cut order will go entirely to the USAF.
    6. In 2009, the USAF says not to worry, they’ll get the aircraft out and fulfill the role the Army needs.
    7. 2012 – JCA cut altogether and the Army left with nothing.

    Anyone know the rational for a flight on a Dash 8 with FlyBe being consistently twice the price of an approximate equivalent on Easyjet?!? (I know Belfast city airport landing charges are extortionate, but it doesn’t come close to explaining the full difference.)

    Surely the economics of a 319 are not twice as good as a Q400?!?

    Realy? Then explain how it has garnered almost the same ammount of orders in half the time as the NEO :confused:

    I’m not sure it has.

    Firm orders ~= “Commitments” (whatever the fook a commitment is – an MoU?)

    Don’t believe everything you read in the papers

    Exactly!

    KLM is not one of the oldest airlines, it is the oldest, so not them. But Iยดll leave it as a maybe.

    As Paolins alludes to, it would make sense to describe KLM as among the oldest – as to state the oldest would completely give the game away.

    My question is – why would an airline keep an order quiet?

    There was one scenario where it could have made some sense:
    In case SU had captured Iceland, some Tu-22M could have harvest supply cargo a/c going from US to Europe, but would have been toast if any real fighter could reach them

    I’d say a MiG-31 would have been the prime weapon for that job.

    Buckets of range, and fast enough to outrun any potentially dangerous adversary.

    I agree. It seems like a baad idea all together.
    Why field such large interceptors, when there exsist weapons systems that could easily take it apart.

    Not if its offensive DEW armament is equally capable of acting in a defensive mode and destroying any incoming AAMs.

    Missiles will be as redundant as the Vickers machine gun when DEWs properly arrive on the scene.

    Military users would rather suffer higher operating costs on the missions where a small aircraft could do the job than buy another airlift type.

    Well, the RAF have just bought a number of second hand 146s for last-mile transport.

    The main drawback of course being side-loading only.

    You gotta wonder is there a market for a skyvan type today.

    Particularly in meeting military, last-mile, transport requirements.

    Yep.

    Only it’ll be DEWS that will differentiate everything.

    – Big enough to generate the power for the lasers.
    – Powerful enough to supercruise to enter and leave battlefields quickly.
    – Heavy enough to have sufficient armouring to withstand DEW attacks upon it.

    But I beleive that active cancellation is something diffferent . It is written on the tin , if I may say : cancelling out the returned signals . It is simpler but harder to archive .

    Think less cancellation, more damping. ๐Ÿ™‚
