    In the UK over 75% of fuel cost is tax (dont have exact figure to hand) and since no government has sorted public transport out we are forced to use cars,unless you live in a city or live near fast rail links of course.
    Labour have always wasted squillions of taxpayers money and taxed us to the hilt to pay for it…. those who voted for Tory Bliar and Grabbing Gordon need not be surprised!!!

    Just to be annoyingly accurate, it’s a Duty not a Tax. A Tax is a % of the original product, a Duty is a slug which is added no matter what the core cost is. Either way, it is money from our backsack into the coffers of the most corrupt Government on Earth. Maybe Nigeria is lower.
    Only a coup can sort it. Voting makes no difference.
    I’m very luck that I walk to work, and 99% of my long distance drives are in a hire car from work.

    To bad the Raptors don’t have a little color like there USN/USMC Cousins!:eek:

    What are the strange shades/markings? looks like it was once camo and they stripped it, leaving stains.

    Now theres an Avro that will need a good going over after disembarkation!

    Holy moly.

    When we were building the 146, the MoD “Borrowed” a couple to see if they were good enough for Queens Flight.
    These two were taken to the edge of the envelope in every condition and direction.
    They were handed back to BAe with a confirmation that the MoD would buy two for HM.
    The ones they borrowed? Sold to Dan Air.

    Thanks for posting the link.

    Good job it was a 146, built like the proverbial brick “outhouse” :-). One of the strongest civil a/c constructions ever. The strongest was the BAC 1-11.
    Not too sure about American / Russian designs, I’ve not seen the drawings of the older stuff. Modern Boeing stuff is optimised by CAD/CAM but they still prefer to stick to very established construction methods, which are also very cheap to produce. I would suggest that Airbus prefer breaking new ground into areas not honed for mass production. As an Engineering piece, they are stunning – almost artwork, to produce the bits is a PITA.

    Modern design has the benefit of the mathematical ability of a PC, so the design is optimised perfectly for the stresses and loads expected. In the older days, adding 10% to your final calculations was a common method…resulting in a slightly heavier construction….but very strong. Not too strong, or it would actually be too stiff and would create its own problems.

    If the MTOW were bigger from the beginning, the A380 would be even heavier. Seeing how Boeing built 747-400ER for just 6 orders, why not build A380-800ER for, say, 20 orders instead of making the baseline A380-800 heavier and losing 50 orders?

    Remind me, did the ER 747 have a shorter fuselage to get the whole weight down? Did the 747SP have a shorter fuse too?
    On the principle of same wing, same fuel capacity, less weight = more range (Unless fuel capacity was lost in belly tanks of the fuse…I have no idea on that)

    in reply to: A380 lifts #551350

    There are devices which are variously called “elevator” or “lift” – boxes used to move people and things vertically.

    In the context of planes, both terms are hard to identify unambiguously, “Elevator” is also a control surface in tail to change the pitch of the plane. “Lift” is the force that lifts the plane into air, and the act of so moving.

    Some planes contain lifts. Tristars and DC-10s contain underbelly galleys and lifts to deliver food and stewardesses; but those galleys and lifts are for crew only. People occupy 747 upper deck, but both crew and passengers get there by a narrow staircase. Some 747s, not all, have a lift to deliver food to upper deck, but not people.

    A380, however, has 2 lifts meant for people. One in the tail next to rear staircase and another in front, some way behind grand staircase.

    SQ A380 has been in service for over 3 months, and there have been other interiors on Airbus test/publicity frames.

    Something I miss is lack of comments and images of A380 lifts. Has anyone seen them?

    ….and if you’re in the Wing Design office and ask for the Lift team, you will be directed to the engineers responsible for the OML of the wing and the moveables that assist the climb!

    And, do you really miss information on “Vertical people propelled transportation systems”?

    (Sorry, went American for a minute then)

    Even a small increase in A380 range would raise the question of routes like SYD-HOU (13800 km), Sydney-Dallas or SYD-GRU (13400km).

    Would markets exist?

    Incidentally, A380 being 4 engine and free of ETOPS would help because the route between SYD-GRU and especially MEL-GRU go pretty antarctic…

    If the demand was there, or is about to be there the A380 would have been designed to do the distance. The developing world has been considered in the range planner. As stated above, it fills the existing and near term demand profile. Syd to Hou are developed centres, no potential growth of trade between the two.
    And don’t forget, the concept of the A380 was “Hub-spoke”. Replacing multi-flights to near locations. Eg if there is a Flight from NY to Milan and on same day a flight to Turin, one A380 would fly to “Italy” and the pax have to hop on a puddle-jumper for the final spoke.
    The F is presently on hold, as you know. The weight problem on the ordinary one has magnified in the F design so it’s head-scratching time at Airbus.

    There is plenty of scope to extend the fuse with a plug, should the need arise. IIRC the existing engines can cope with the extra MTOW.

    While the currently operating B-52H are all from 59 to 61. Still the B-52 was plagued by structural fatigue issues (can’t say if all models to the same extent). The questions remains on how the Soviets deployed their Tu-95 and how many hours actually were flown. There are examples of aircraft that virtually were decommissioned over night, for example the Vickers Valiant.

    The “Age” of a platform is always taken as from first flight to retirement of the last build or last upgraded. I read somewhere that the last upgraded B-52 could very well retire in 2050, making “it” (The platform) a 100 year old! Is that a plausible situation?

    And the joke was originally, “I retire with the same hammer I was given as an apprentice, I’ve had it for 40 years. Only 3 heads and 20 shafts have ever been fitted”

    Part to me says that this is cool, another part says this is very unsafe.

    Certain Special Forces have been using that method for more than a decade.

    It could be unsafe near the mountain side or close to the ground, as we know wind directions are different there..plus microbursts etc. They have no recovery envelope!
    I’m just jealous, too old and too many responsibilities to do it! That’s my excuse and I’m sticking to it 🙂
    But it looks like the most exhilarating non-powered flying sport ever!

    It also has something embedded in the windscreen…..

    I took this at MAKS last August…..

    Heating element ?? Plasma Stealth generator ??:eek:

    Obviously not MDC :-). Must be something to do with the flight test plan as it is clearly an obstruction and probably won’t turn up on the in-service models.

    Thanks.

    I travel into Wales much further north via Welshpool.

    Cheers for that.
    When I lived there, the machines would scream up the Usk Valley NW direction, (About 200 feet over my house) and I always assumed that once into the hills the hill-hugging was on MoD land and not accessible to public.
    As I said, Damn!
    The lowest platform I saw was a EH101 at about twice the height of the trees travelling at what seemed an unfeasible speed for that level. He was following the course of the river exactly.
    I also saw (Once only) a C-17 go in low then climb to drop paras. That was in 2004.
    The low level activity also continued in darkness, up to about 11pm. Judging by the engine noise it was probably Harriers and Tonkas.

    It probably will resemble the A400 (which kinda resembles the C-130) but it will be an all new A/C……have better performance than the A400….. be cheaper than the A400….and then this whole stupid argument can continue…….until the end of time!

    A new squadron of plus the Airfield, Support and Spares will be cheaper than A400. 🙂
    Maybe not the selling price, which has been committed by Airbus Mil. but they will lose their shirt on it, unless they can sell to Saudi or similar for the usual inflated mark-up.
    At the end of the day, it’s giving Britain and Europe Defence/Aerospace jobs which we need to retain and grow.
    I know a cheaper alternative was available, but politically the partner nations “Had” to go for a design/build option.

    Stunning.

    In the 3 years I lived in that area (And didn’t use this forum), I didn’t know there was a viewing position higher than the machines.
    Damn.

    You probably pass my old house en route, I lived on the A40 near Crickhowell.
