    CO is insidiously dangerous, it is not just toxic, by its nature it excludes Oxygen. Also remember CO sensors are electrochemical cells, sometimes biochemical and as such ALL have a limited life. Always discard as recommended by the manufacturer.

    Do a search on Tumby bay airfield in South Australia. About 7 years ago a Grumman and a RAAus registered Jabiru 230 collided on final. The Jabiru was on the new CTAF frequency and the Grumman was on the old CTAF frequency they were in the circuit together and obviously neither heard the other's calls because of the frequency conflict. Classic reason to not change CTAFs unless absolutely necessary. The impact occurred just as both aircraft were flaring for landing; the Grumman on top of the Jabiru. All crew survived; nothing short of a bloody miracle. The Jabiru pilot was an associate of mine. The Grumman propeller chopped the tail off the Jabiru. There was another one at Cessnock NSW mid 80s that I remember. There have been a significant number over the years and often are low wing on top of high wing.

    Interesting watch. Some of this stuff not well known about the LIPOs. It beggers belief that anyone would just automatically think that a whole new battery technology can simply be bolted up to a standard Alternator for charging. Most should know by now that LiPOs can take a full charge voltage right up to fully charged and the current stays up there. This will result in alternator over heat unless you over size your alternators ro, as Victron suggest install a temp monimtoring management system to reduce the charge current as the alt temp rises. Victron are one of the best in this field of research, I run some of their gear and about to run a whole more in off grid systems.

    Hi Arthur, That photograph is the Hornet isnt it? I thought the wasp was the two seat tandem tail wheel; at least the prototype I saw was.

    That would be David and Caroline Salter; truly lovely folks. Probably the most experienced Beaver pilot in the world; he did a lot of Ag development with de Havilland back in the early Beaver days.

    They are a lovely balanced aircarft to fly. I loved flying one from the front seat some years back.

    It will be in the by laws, look them up on line. Membership classes and rules are usually set in the by laws. If it says they can, they can. Quite common today. Bit difficult if you don't have an email ... LOL

    Blood nice little aircraft they were. What is this one powered by and how old is it?
  10. David Isaac
    Very much so ... Ross was an endearing helpful little bugga. Our little community noticeably misses him.

    Motz, Was there ever an accident report? Likewise, I never saw one on the Wayne Fisher accident either. These were two accidents of great interest to the community.
  12. David Isaac
    Definitely a big loss to our small community. Sadly missed.
  13. David Isaac
    This is a terrible loss, especially as a father and son. I think of myself and my boys and how this could have happened to me all those years ago in my VFR flight into IMC incident ... I was very fortunate that day. From all reports these were really decent people; but these kinds of accidents have no respect for persons and terribly unforgiving of errors of judgement. From all accounts on the news from friends who were interviewed, these were a really good family who gave a tremendous amount to the community. My heart goes out to the family.

    Sydney is down to one runway (East West) due wind, that will cause chaos. I have just had my 12:20 Q flight out of Mt Isa cancelled and put on a 18:00 flight which gets me into Brisbane too late to get a flight to Sydney and in any case no available flights ATM from Brisbane to Sydney, so stuck in Brisbane overnight. Wouldn't be so bad if this wasn't the fourth day in a row Q have cancelled the midday flight out of Mt Isa; and they don't tell you till the morning of the flight. Doesn't stop them blaming the weather though for all four days. We try to get on line to change the flights from what they have selected and it says cant change on line and to call them. We try and call then and its a one hour + call queue, 30 minutes in, the call drops out. We go to the airport to get assistance ... no Q staff anywhere, because the flight has been cancelled and a bunch of people there who didn't get the message. Bloody great service Q, no one there on one of the most lucrative routes you sell. Cut the costs out of the business so much that it is now hurting your reputation. Real bugga, as I had a family commitment tonight. Commercial aviation, becoming almost as unreliable as private flying.

    What beach landing ... get my drift.

    I agree totally with the caution that Skippy diesel is suggesting. I have been vocal in the past for the same reason when I see some absurd claims for takeoff distance that do NOT use the standard professional aviation convention quoting take off distance to a 50’ obstacle clearance ... after all that is the real distance; or Absurd claims to stall speeds that can never be achieved without any reference as to whether there is any ‘position error’, or whether it is IAS, or CAS; and Absurd claims to STOL performance that state the damn thing can also cruise at ‘120 knots’ with absolutely no reference to the turbulence penetration limitations. References to cruise speed that would have to be at WOT to be anywhere near possible, certainly not any reference to cruise speed at say 75% power with a relevant fuel burn rate; and Then there is the old chestnut ‘G’ structural rating when many of the claims I have seen are NOT a ‘rating’ but more a structural limit ... which is something you don’t want to be anywhere near. It is almost that since LSA aircraft came out, much of the sales hype disregarded professional avaition convention just to BS to uneducated purchasers.

    You think ... that is the problem with this routine, it encourages illegal operations. You can bet it is happening where no one would notice. Hardly likely to be pulled over in cloud 9 by the air patrol and asked to show your license.
  18. David Isaac
    Yep ... can you believe some of the BS that CASA come up with because they think it covers their ass. The only way they would be happy with risk mitigation is to ban flying altogether.

    Kyle, it does matter in cases where the reason for the failure of the class 2 was temporary. e.g. in my case 4 migraines. BUT the problem was that once you lose a class 2, however temporary, you automatically fail the RAMPC, because one of the pre-conditions was that that you had never been refused a class 2 medical. In my case, I had to go back to a class 2 DAME, it was my only option. It looks like that provision is no longer there because they have now said "exactly the same as the commercial driver standard (Austroads)".
  20. David Isaac
    Actually I get the unconditional bit; I was looking that they appear to have removed the extra CASA conditions from the Austroads medical that was in the RAMPC medical. The problem with the old RAMPC was that one of the conditions was that if you had failed a previous class 2 you couldn't get a RAMPC and had to go the DAME class 2 route anyway, and it looks like that provision has been removed. Did I get that bit right???

    The old adage ... you get what you pay for. After similar experiences to all of the above that Ian and others have shared, I vowed to NEVER (unless I am forced to) travel with shitstar again. At least if Virgin and Qantas cancel, they do everything they can to look after you.
  22. David Isaac
    Mag, Except this time the Basic Class 2 medical standard is "exactly the same as the commercial driver standard (Austroads)" this is quoted directly from the CASA 'Classes of Medical Certificates' page you provided the link for. So it has changed, before it was the Austroads plus a whole lot of other CASA requirements which meant most of us who had some minor problem that suspended our original class 1s or 2s (in my case 4 migraine headaches) could never get what was the old RAMPC. On this basis if it is what they say "exactly the same as the commercial driver standard (Austroads)", then, most of us could pass at least that. So unless I am reading this incorrectly it has changed for the better. So am I reading this correctly?

    I think I have had a relapse and the ADHHHHHHHD has kicked back in ... I am bouncing off the walls and missing you terribly HH. XXXOOO.

    Wayne fisher built several strut braced 912uls powered versions. He told me the strut braced was much heavier as the trailing and leading tubes were double tubed (one inside the other). The Drifter is a fantastic fun machine. The early wired braced Maxairs were the lightest and the most agile and my favourite.
