    Anyone happen to know the status/outlook for the Yak-3 G-CDBJ? It’s the only one besides G-OLEG on the UK registry, but was damaged in a landing accident 11 years ago. Last I heard was that it was undergoing repairs, but I don’t recall seeing anything of the aircraft since 2008 when it was still flying.

    I always understood it to be at Pent Farm but as it didn’t get back to flying soon, imagined it would become increasingly less likely to. I’m somewhat perturbed to see the owner listed as ‘deceased’ on G-INFO, I vaguely knew him some years ago.

    Perhaps of interest to someone, the Riley Heron based in Sweden is up for sale on planecheck.

    Sorry, can’t help with 3-views but there are 2 Beech 18s on floats for sale on Controller with pictures, which you might find useful.

    Air France-KLM are cutting 3000 jobs:

    Regardless of what the financial arrangements actually are, under the circumstances, maybe its felt that continuing operation gives the wrong impression.

    Does anything modern still use pneumatics?
    I know that the British aircraft industry championed it but I have also heard pilots swearing at it for unreliable brakes in particular.
    Also noted how Spitfire legs sometimes don’t retract quickly when someone pulls G during the retract cycle.

    Not that I’m aware of, apart from de-iceing boots, although I remember reading recently about potentially using engine bleed air and air motors to replace hydraulics.

    Also, early variable pitch propellors used to be electric but since changed to hydraulics.

    Can anyone tell me more about this plane? The wings look kind of familiar! Now where have I seen that eliptical shape before??

    Its a Silence Twister, a German kit-built plane.

    Conversely, modern P-47’s are probably a bit lighter without armour, lighter radio’s, etc.

    Is this the same Mosquito that was advertised for sale a couple of years ago and had the plug pulled at a late stage in the negotiating process?

    PS: Much as I love Jargon, can someone explain in plain English, is there a major problem with certifying this particular aircraft, or is it time honoured British civil service preoccupation with crossing T’s and dotting I’s?

    I’ll give it a go/guess.

    I don’t think it’s the particular aircraft, its generally, because:
    1. It’s not a certified aircraft, so no certificate of airworthiness can be issued.
    2. It’s not a former military aircraft with a judgeable safety record and is not an unsupported but previously supported/type certified aircraft, so no CAA permit to fly.
    3. It’s way too heavy to be regulated by the Popular Flying Assoc. who deal with kits & homebuilt types, so no PFA Permit to fly.

    What’s so miraculous about ABS?

    I know that, in extremis, I can brake my car faster with manual cadence braking than the abs system ever can. OK the steering and braking thing I can’t do as well, but then again years of ingrained training means I have never in a moment of need remembered that I can brake hard and steer at the same time.

    Moggy

    What would even be the point of ABS? Airliners & biz jets, wet runways, fairly obvious, but on smaller planes, bumpy short strips would it be any benefit?

    I know ABS is available on motorbikes, but believe its not particularly helpful on offroad bikes, same thing as a strip aircraft I would have thought.

    Does that include the ex RAF, RN Gazelle’s and Bulldogs?

    James

    The Bulldogs are supported through deHavilland Support.

    Not too sure about all the Gazelles but some I think (the RAF ones?) were the same as the civil version but the RN ones didn’t have a direct civil counterpart (mostly the addition of a stability system I think) so can only fly on a permit, presamably meaning they aren’t necessarily supported by Aerospatiale/Westland/Eurocopter.

    Correct me if I’m wrong.

    I think you will find that the manufacturer does not wish to support the Wessex in a private or commercial capacity and in some countries ex-military machines are definately not permitted.

    In the UK, ex-military aircaft cannot be used commercially unless identical to a type-certified civil version, but can be issued a permit to fly, i.e. privately, if approved by the CAA.

    Hunters, Jet Provosts, Sea Vixen, Spitfires, etc. aren’t supported types but fly.

    As for certification ??? its an international aircraft with no real home, so to get the thing off the ground, complete the initial certification in the most convenient country, you will be stunned and amazed how much time and money can be saved.;)

    Yeah, but some of the less enlightened aviation authorities, such as the CAA, FAA, DGAC, EASA, etc. may not take your type certificate issued by the aviation authorities of Swaziland or Bhutan very seriously.

    “Its got nothing to do with money”

    Its got everything to do with money. Development costs money, certification costs money. New things are mostly being done by new, small companies. Establishing enough credibility so enough people are prepared to plop down a substantial amount of money, comfortable that companies such as those will still be there 10 years down the line to support their plane is very difficult and takes a lot of money.

    There is interest in new technology – witness glass cockpits, diesel engines, composite aircraft such Cirruseses, Diamonds, etc. However, with anything new you take a risk of uncertainty. With something as expensive as a plane, that risk in terms of reliability, parts availability, resale value, etc appears to be large enough that lots of people will prefer to go with a known quantity, i.e. a Piper or Cessna. As long as that situation exists those types of manufacturers don’t really have much reason to do anything particularly groundbreaking.

    Things such as anti-lock brakes you mention will need certifying, servicing, training of mechanics, etc. All this, and no doubt a lot else, combines to make this just too expensive for what is already an expensive activity which has a much more limited market than the automotive or motorcycle market you’ve referred to once or twice.
