    I just had a answer back from Eprop on the time for their props..there is no time constraint only the 4000 hours due to the way they are made and the special material they use

    Thank you for the follow-up.

     

    if there is a like for like performance comparison against a DUC Swirl 3,

    anywhere, I’d be interested in reading it. I will need to make a prop decision in about 6 months.Standard figment is a DUC.

    The Latest Outstanding Communication from RA-Aus

    I had a leaky mitral heart valve resulting in breathlessness on exertion. I voluntarily grounded myself but hadn’t got around to formally advising CASA. On my most recent visit with the cardiologist involving a treadmill stress test, ecg, ultrasound etc. the leaky valve problem has completely resolved by itself, and the cardiologist doesn’t wish to see me for at least two years.

     

    Do I inform CASA that I had an unreported historical problem, but now I don’t ?

    New Aussie Turboprop engine (200 HP) introduced at Sun 'n Fun

    Turb Aero are talking about engine replacement for O-320's and O-360's - so they're talking GA, not RA. Engine designs have to be continually refined and often redesigned, when serious reliability flaws show up after several hundred hours of extensive testing. So it's not just the actual certification cost, it's the continued engineering expenditure and testing costs that keep eating into the available funds.

     

    There are dozens and dozens of "new design aircraft engine" companies who have spent years, and sometimes decades, trying to commercialise their "new design engine", and very few have made it to market - but the vast majority of them have run out of development money - or struck insurmountable engineering/efficiency hurdles.

     

    Even Clessie Cummins took 18 years to gain a market, and to start making a profit from his diesel engines - and he was backed all the way by a banker (William G. Irwin), who poured $2.5M into Cummins over nearly a couple of decades - between 1918 and 1937 - the equivalent of hundreds of millions of dollars today.

     

    The NZ Duke axial engine has been in development since 1993, and in 2023, Duke Engines are still seeking "international partners" to continue the development of their engine to the stage of a viable and alternative aircraft engine.

    Don’t hear much about the Sarich orbital engine these days, although the ASX listed company still exists albeit pursuing different technologies now.

    Yes, it can be a really tricky situation needing a lot of judgement and experience to manage safely.

     

    And if your ab initio training happens to have been at either a controlled airport - where you are told exactly what to do - or at a very quiet strip - where you might never have needed to negotiate sequencing with anyone, you'd be very unprepared when arriving at a busy uncontrolled regional port. Especially one where RPT traffic's involved.  Throw in multiple runways and the game of checkers turns to chess.

     

    So maybe complex uncontrolled circuit work should be a specific subject on the syllabus. Although good places to train are not always easily available.

     

    Failing that, I've sometimes thought that a cricket pitch might make a fine classroom for some cheap basic training ; a bunch of fellow students walking the 'circuit' (at various speeds) yelling out their locations and intentions.  Maybe an arm in the air indicating 500' above and knuckle dragging, 500' below.

     

    (Of course, all done at the risk of being bundled off by the constabulary to a safe place somewhere   ;- )

     

     

    Your cricket pitch idea is right on the money. Scouts are taught circuit procedures using a fence paling as the runway and a garden hose laid out in a rectangle representing the circuit. They then ‘fly the circuit’ by walking along the hose, and know what they need to do on each leg of the circuit.  Much more effective than a blackboard.

    Sometimes you have to buzz the squatters though !

    Light plane crash The Oaks, 30 March 2023 (edited)

    Time and time again, we have this complaint from our end of the aviation spectrum. But what do we do about it? Moan in places like this. 

     

    What is needed is for those at the grassroots to take positive action. What about a massive campaign against this false news. Write letters of complaint to the broadcasters and any relevant government agency. Why not threaten these media outlets with litigation for telling the public untruths?

     

    The squeaky wheel gets the oil. We can only change the media's methods by being that wheel and squeaking and squealing.


     

    it gets worse……

     

    The Daily Mail known for entertainment, not news, appears to cobble together whatever they think will sell a story.

     

    Apparently this guy broke his leg, but the post crash video (where he of course was posting to social media) shows him walking just fine.

    OME, I appreciate the sentiment and indignation, but taking on the likes of Murdoch would take a global movement somewhat larger than what can be mobilised here.  And it’s not just Murdoch, the Daily Mail is owned by a Viscount.

     

    Sigh.

    Was this really a 'chute worthy' emergency?

    in Aircraft Incidents and Accidents

    Posted

    I was told of an incident in Germany where a student had an engine failure in a LSA in the circuit and elected to pull the chute. There was a lot of head scratching as to why a forced landing on the adjacent 1000m bitumen strip wasn’t attempted. I guess none of us know how we will react to the startle effect.

     

    Regardless, the student walked away from it, and despite the ‘chute’ landing, the aircraft was back flying again within 6 weeks.

    Crazy aircraft prices

    in AUS/NZ General Discussion

    Posted

    A European LSA aircraft I was looking at had a 5% price rise in Nov last year in response to rises in input costs in Europe. This was on top of a similar price rise the year before, but I think that was still less than inflation in Europe. The big killer was the substantial increase in global shipping costs last year to ridiculous levels and very long lead times.

     

    No doubt rising sale prices of new aircraft raises the value of 2nd hand aircraft as well. Particularly in Australia where importing aircraft is an expensive and pain in the A exercise. So the old adage of ‘having the right stuff at the right place at the right time means you can charge whatever you want’, tends to hold true.

    Its a personal cost/benefit decision in what the extra slice of Swiss cheese is worth.

     

    I currently drive a 27 year old car that has no airbags or ABS brakes. Do I feel safe in it ? Not particularly, but I still drive it at 110kph on the motorway. If I were to buy a new car though, I would expect it to have the latest safety features.

     

    For a new LSA type aircraft that I was looking at, a BRS system was about the same price as an optional three-colour paint scheme (vs 2 colour). What should I choose ?

     

    I understand the 7kg in extra weight is significant in some LSA aircraft.

    because of the ballistics involved , there are protocols regarding the access to aircraft by rescue teams if the said ballistics have NOT been activated !!!

    In Germany, BRS was made mandatory as a compensation for the relaxed certification requirements for “microlights” which were originally limited to 472.5kg. This category has more recently been raised to 600kg MTOW.

     

    Oh, and also mandatory in Italy, since 2010.
