Re: Translation please
I braved the comments on the Guardian article, so you don't have to, and I'd say ~90% were supporting the guy which made me feel slightly more hopeful for our species. I'm also now committed to getting a similar shirt in case I ever have to appear on TV. I won't be apologising though.

Re: Awesome Toy
I'm guessing something to do with vortex ring issues. In real helicopters if you descend with too low a forward airspeed you end up descending in your own downwash and can get in a position where applying more power merely results in you descending faster.
Although it's a bit simpler from a dynamic point of view in that it's relying on fixed pitch, variable speed, rotors it's probably liable to the same issue so they may have limited the max descent rate to avoid people making expensive holes in the ground.
Too true, an actual expert would know to keep his mouth shut until there were some facts to evaluate.
Re: Why are these guys even in charge?
You seem to be confused about the point of air accident investigation. It's to find the cause and prevent recurrence. Who do you want to do that, the people who designed, manufactured and operated the thing that just went expensively wrong and who have a vested interest in the outcome of the investigation, or an independent body of experts?
After all if de Havilland had investigated the early Comet crashes who knows what they might have found the cause to be.
No you may disagree with this, but you'll have to change international law to let Scaled Composites investigate their own crash and frankly I'm not convinced anyone's going to go for that. Especially if it means Boeing being allowed to investigate why their 787s keep catching fire.
Not really, if it's a fleet of drone boats there won't be anyone to worry about accidentally killing if the launch doesn't go to plan. Of course being North Korea they may not object to putting some passengers on the drone boats...
Re: "the Camel, best all-round fighter of the First World War"
Talking of wing stiffness, the Seafire XV which was the first fitted with a Griffon engine, could suffer wing twisting at high speed when the ailerons were deflected. Essentially rather than rotating the aircraft the force on the wing caused it to twist and the aircraft to roll the opposite way to that expected. It tended to end badly for those involved.
I think the Sea Fury was actually the last sleeve valve engined aircraft produced, using the Bristol Centaurus, although that too was a Hawker aircraft being a decendent of the Tempest. It was as fast as the early jets and shot down at east 1 MiG-15 in Korea.
Having said that the Airspeed Ambassador also used the Centaurus and I'm not sure what the production dates were for that.
Incidentally the original aim of the sleeve valve, as I understand it, was to reduce the diameter of the engine by removing the valve gear which lead to less frontal area and drag.
Steven Moffat peaked at series 3 of Coupling, everything since then has been on a downward trajectory. And I'm not alright with that, because Joking Apart and Coupling were genius and Capaldi and Coleman are decent actors, hell Coleman must be because she has to play a different character every episode, but the Who since Xmas have been bobbins.
Re: Eyes drawn to movement
There was a sketch on John Finnemore's Souvenir Programme the other week about this where an enterprising head teacher had placed TVs in the corner of all the classrooms playing slightly out of tune subtitled Open University lectures while the teachers stood at the front of the class talking about whatever they wanted. It'll be on that iPlayer thing somewhere and be much funnier than I just made it sound.
So it isn't for Hyperactive Twat like the one out of Steps then?
If it could be embarrassing it would be OFFICIAL - SENSITIVE which has extra handling precautions, almost like CONFIDENTIAL used to. I don't know if the GCHQ assessment makes that distinction though.
Re: US import regulations.
In a past life I worked for an oil well service company. Some countries we worked in had significantly more Kafkaesque customs regulations than others, to the extent it was easier for personnel to take equipment in their luggage rather than going through official import channels. The worst I'm personally aware of, i.e. saw happen, was some poor sod taking most of a rack mounted computer system as his 'luggage' to Bangladesh. Fortunately the company reimbursed the $1000+ excess baggage charge before his credit card bill came...

Oddly the main criteria for selecting Faslane had nothing to do with access to the ocean (it's at the end of a sea loch into a relatively shallow sea so it takes a while to get to true deep water) or distance from London (after all the Atomic Weapons Establishment is really quite close to the capital). It's because they wanted the cloudiest place in the country so Soviet satellites couldn't spy on the SSBN fleet. This is why it's always raining when you go to Faslane.
Re: You can't get thrown out of something you are not part of.
'So Scotland isn't currently part of the EU?'
I believe the argument is that the United Kingdom is part of the EU, if Scotland leaves the United Kingdom it's not part of the EU as Scotland isn't signed up to the EU as an individual state.
Think of it like RAC Membership*, you can be a family member as part of a family if you leave that family then you're no longer part of the RAC and if you join as an individual you start from scratch.

Re: If you're looking for a film to watch this weekend
Second for The Guest, certainly one of the better films I've seen this year. I mean it's no Lego Movie but still probably top five for me.
Is this new?
Obviously it's a bit worrying something like that can sneak up on us, but, is this a case of we've only just got to the stage where we have the technology to notice this stuff or are 2014 RC and the Chelyabinsk asteriod/meteor/magma an exceptional coincidence?
Re: Give it a few years...
Even better, weigh them and then allocate their seat, or at least restrict the ones they can choose from if necessary. That way you save on asking all the lard-os down the back to move to the middle after everyone's got their hand luggage stowed.
A work 'colleague' is on holiday in the USA and we were rather hoping the thing would erupt and keep him there indefinitely.
Plus we could have grounded all our aircraft, which from a flight safety point of view is the perfect situation.
They were married?!
Sorry, I didn't realise, there was no effort whatsoever in the rest of the programme to get that message across. Maybe they should have made constant reference to it at the expense of the narrative.
'It's under the dash in the driver's footwell. Any new car sold in Europe for the last ten years is required to have one.'
It's possible the poster is referring to the original Mini Cooper S which is of course far superior to the current version that is far from mini. In which case it's barely got an electrical system never mind ODBII or a 12 volt adaptor/cigar lighter.
Re: Step back and thnk about this.
'I've always worried why the Nimrod (based on the Comet 4) was kept in servie so such a long time, but I surpose that is more a question around MOD purchasing/specifications and the almighty mess that is'
Probably for similar reasons to the Nimrod MRA4 program having its name changed from Nimrod 2000 when it became readily apparant BAe Systems were never going to make the original delivery date. It's almost as if they lied to get the contract...
In this case I don't think they're talking about the human factor in terms of gaining access to the computer, I think they mean in overcoming what happens next. E.g. the computer may be hacked so the flight plan takes you to the wrong place but the humans should notice that and question it. Of course that depends on the quality of human being employed, I think Ryan Air try and beat out any tendency for the pilot to think for themselves at an early stage in case it costs money.
Re: Step back and thnk about this.
'Try that on a podded engine and you'll find yourself flying in a corkscrew pattern thanks to the drag of windmilling fans'
So you're saying a windmilling engine inside the wing won't cause drag? Because I'd like to know how that magic works.
Of course if the podded engine is a higher bypass ratio then it may cause more drag, but then it's more fuel efficient when running and it wouldn't fit inside the wing anyway. It also allows you to build a lighter wing structure as the mass of the engine counters the aerodynamic twisting loads, whereas an integral engine doesn't.
Rivet Joint has the slight advantage that there are a few hundred of the basic airframe in service, vs the 20 max for the Nimrod. It makes getting parts easier.
Re: Collision avoidance system
From my understanding of how the ACAS/TCAS systems work it wouldn't really matter if you obeyed a false alarm as all it will have told you to do is make a climb or descent to avoid an aircraft that isn't there. The descent advisory is suppressed below a certain altitude above ground level as well so it won't order you into the ground.
You might, might, be able to confues the box as to which aircraft should climb and which should descend, which is based on serial number I think, but that means you'd have to be willing to sacrifice your spoofing platform, and get it in the right place to ensure a TCAS resolution advisory gets triggered agains your target aircraft. Which is the kind of non-trivial problem that makes air defence systems so expensive.
Re: Attacker vs Attacker
ACAS is not a radar, what they're talking about is spoofing the collision avoidance system to make the aircraft manoeuvre to avoid something that isn't there. To do that you'd have to transmit a series of transponder returns from a consistent position relative to the target aircraft.
It may be possible to hack the ACAS box, Google TCAS for an explanation of how it works, and I'm not sure how they're integrated into a modern airliner so their data is displayed on the flight displays. However it's perfectly possible to have it as a standalone box that only takes power from the aircraft.
Heck, it's not even digital
And yet it works, it's as if you don't need a series of 1s and 0s in the real world...
Re: Former UK
On a vaguely related note, for about the last decade there's been a French, Russian, UK and US naval exercise every year. Known as FRUKUS. I'm really hoping Russia aren't invited this year....
Re: UK still leads the way in ripping off the taxpayer
'The UK is densely populated but we mainly live in towns & cities. Over 90% of the UK is rural, park, or undeveloped.'
Yes but annoyingly the railways tend to what to go where the people are as park benches and cows rarely use their service.
'Is it the job of the ordinary taxpayer to pay the ridiculous price of HS2 because the WCML is clogged by fat cats travelling first class? '
That depends, if the people travelling first class are subsidising the fares then your plan results in all the people who normally travel second class having to pay more anyway.
Well that explains how my card got used to spend $400 in Target last month. It doesn't answer the question why would you rip off a credit card and shop in Target mind you.
Still as I'm from the UK my bank were speaking to me as it happened so the card was cancelled straight away.
Re: We know, you know.
I'd suggest if your friend was in the TA his background may have been more thoroughly checked than your average punter at the airport. The questions about your relatives on the standard security vetting form are almost as intrusive as the State Departments visa application for people from the Middle East. Mind you they don't seem to notice if you make stuff up on that as the 50 members of the Iraqi Navy I completed the forms for all got in and out okay and I made half of it up...

Re: SkippyBing a navalised Typhoon
'Scimitars had fallen out of operational use at sea by 1966.'
As had the Buccaneer S1 which was the model that couldn't get off the deck with full weapons and fuel. The S2 had about 50℅ more thrust so was far less limited in what it could launch with and so less reliant on tankers. And actually useful as a tanker.
If you want to be really pedantic you could point out that of the two carriers that deployed the Mk1 Buccaneer only Eagle carried Scimitar tankers as Victorious didn't have the room. This meant the Vixens of 893 had to double up as tankers as the S1 Bucc was pointless in the role as it couldn't carry enough spare fuel, much like a marinised Typhoon would be.
Re: You think aircraft carriers are expensive...
'Considering that Nimrods were Comet 1 airframes (yes, the very same that embarrassingly broke up in flight) I reckon they did pretty well.'
Yeah, until one blew up in mid air killing 14 people because BAe Systems lied about the safety case .
That's kind of my point, they adjust for different aircraft by altering the steam pressure, it's really the only variable there is. That's why in the linked pictures of cars and pianos going off the bow they don't go that far to avoid damaging the cat. Although you do wonder why they didn't try full pressure on the piano they launched off the Ark at the end of her last commission, it's not like they were going to use it again!
Re: You think aircraft carriers are expensive...
'Well thats what you get if you don't build it here'
As I understand it BAe are also making part of the fuselage of every F-35. In fact something like 20% of the total build is from UK industry, which over the course of the programme will probably be of greater value than if we had a 100% UK built aircraft and then only brought a hundred or so of them.
Re: SkippyBing a navalised Typhoon
'Ignoring buddy-refuelling tanks, you mean?'
There's not a lot of fuel in buddy-buddy tanks*, normally the tanker also transfers fuel from it's internal tankage and as many external tanks they can hang off the thing. Ideally you want a tanker carrying as much fuel as possible, not launching one tanker per fighter as you'd soon run out of room on the boat.
There's also the issue of arrested landings where you need a tanker airborne to top up anyone who's delayed landing for whatever reason** otherwise you soon run out of aircraft as they typically only plan to have enough fuel for a couple of approaches, to minimise landing mass. For VSTOL aircraft this is less of a problem as they seem to get the landing right first time.
V-22 could work and would be an idea for F-35 as well, plus they'd make a more useful AEW platform. Alas I don't think the Treasury/Defence Logistics would be happy adding another type to the UK order of battle as they've spent the last few years trying to get us down to two fast jet and four helicopter platforms. Although it's still going to be a decade or so for that last one to pan out.
*In absolute terms there's quite a bit but not in fast jet terms and then half the tank is gubbins for transferring fuel.
**Either messing up their own approach a number of times, or someone else doing it and causing the recovery time to slip right.
