    So says the moderator of a discussion forum. Brilliant.

    Obviously you cared a few minutes ago to reply but now that I’ve replied you don’t care. Excellent. For someone with 16000 (honestly) posts you seem to have a particularly poor grasp of what these discussion forums are all about.

    Your points 1 to 6 are so full of mistakes that it might take me a while – I’ll reply when I’ve stopped laughing. On the other hand they say ignorance is bliss so why change it?

    I’m an opponent of Scottish independence but arrogant English attitudes do make me waver at times.

    OK I’ll ask a question in easier words. Why does anyone think that the break-up of the UK is a good idea?

    Sadly Al and many I know like him have fallen for Salmond’s rhetoric and bluster. He is a skilled politician but he is starting to waver when bit by bit the reality is starting to show itself.
    There is no doubt that Scotland has done better under an SNP government but only one that is still part of the UK.
    Of course if the YES vote wins then it will be truly independent now; no Euro, no pound, no EU. Nothing.
    Interesting that Norway is held up as the example. It used to be Iceland and look what happened there.

    Ignoring moderator’s obvious trolling and his inability to answer a simple question I put to him ages ago, I have a simple question for Al.

    Do you agree that anyone’s citizenship should be allowed to be changed without that person having a say?

    It can’t have been that great an great idea as no-one else has done it. I think the Short Sperrin had engines that were top of each other mouned on the wings.

    Meanwhile back at the original thread…. (why do we need two?)

    It’s rather sad that all sections of the press seem to want to do is blame someone. It’s the weather. Pure and simple. The wettest since records began.

    Why is that sad? In my opinion it’s a great thing.

    I’m not sure why anyone would think the break up of the United Kingdom is a good thing but there you go.

    In the event of independence I would have thought that Scotland would be entitled to a share of the UK’s gold reserve.

    The fact is that being tied to the Euro or the pound means that independence is nothing of the sort.

    Salmond has deliberately disenfranchised large numbers of Scots; Scots who would largely vote “No” – that is despite the fact that my citizenship will be directly affected by a “Yes”, I do not get a say in that process. What is sad is that so many Scots are falling for his rhetoric and false promises. Let’s hope common sense prevails in September.

    Sadly Cameron and his fag Gideon getting involved is a great boost for the Yes campaign.

    And you would complain if they never appeared at all.

    I have to say that I find this linking of the UK floods and the overseas aid budget very distasteful and is fairly typical of the UKIP/Daily Mail type intellect.
    Those who benefit from UK aid should not be denied help because of some tawdry campaign by the worst aspects of the UK press. The Prime Minister has stated that “money is no object” so funds do not need to be diverted from anywhere.

    The floods have been caused by the weather – lots of it. No-one can say for certain if dredging/defences etc would have helped but lots of people seem to be wise after the event.

    Be safe…

    No news on India or Pakistan sending us disaster aid yet…:rolleyes:

    Maybe when our floods are as bad as theirs then they might…..

    You’re right. I do indeed find it impossible to comprehend how anyone can think that designing an aircraft only has to take speed and drag and power into consideration.
    Do you have any idea how strong (and therefore heavy)it will have to be structurally to maintain a cabin of 8000ft at 80000ft altitude?
    De-icing or anti-icing needs to work close to the ground as well as in free air -it needs to heat leading edges and propellers and pitots and static vents – all of which needs electricity.
    How large do you think the landing gear will need to be to hold up something bigger than a Tu95 and how much power wil it take to retract it?
    Maybe you can only fly on sunny days and take passengers who generate their own power by pedalling for 26hours. Good luck with that!

    It might not be CS-25 exactly but many of the rules are there to protect the fare-paying public from poor aircraft design so if it wasn’t CS-25 it will be very similar.

    Anyway, you haven’t explained how you are going to generate enough power to pressurize a fuselage to 8000ft cabin while outside is it 82000ft! Where does the bleed air come from? How is it heated to reasonable comfort levels? How do you keep the leading the airframe free from ice? What facilities do passengers need when airborne for over 24hours and how are they powered?
    Designing an airliner is a lot more than speed and power.
    Your solar panels would need to generate at least 20 times the power you are proposing to be even close to how a modern aircraft operates.

    Your design would have to comply with CS-25 otherwise it wouldn’t get a certificate of airworthiness. 40km/h stall speed or not.

    You’re talking about aircraft that would never get a CS-23/25 certification as a passenger aircraft.

    I did a bit of a Google and the nearest 36 seat airliner I could find was a SAAB 340. It uses 2 1300kW engines to fly not very fast and not very high but reasonably efficiently. That’s 76kW per passenger.
    It needs that sort of power to get airborne in a reasonable distance, climb to a reasonable height and fly 34 people to their destination. Your aircraft has 5% of the power so can you tell me it would be able to accelerate to a reasonable take-off speed in around 5000ft, climb to 25000ft and carry its passengers in air conditioned comfort at 0.5M for a couple of hours.
    In addition it has to power the air conditioning, the pressurization, the hydraulics, electrics, anti-icing etc. etc. All from a total of 160kW?

    Oh is that all!

    You have some good ideas and please accept the criticism in the spirit that it is intended.
    I’m not sure why the mods decided that GD was the place for this rather Commercial Aviation. Perhaps they thought that GD had people in it that knew what they were talking about !
