    I have had a Kane 6B computer for over 50 years and don't use it much, mainly as a check to see that Avplan is correct. I have never known how to use thebottom of the high speed side. The bottom is squared off in horizontal and vertical squares. The instruction booklet doesn't mention how to use it. It may be something to do ith cross wind calculations. Does anyone here know?

    To do the job properly you need an EGT gauge. Watch your EGT at take off, full rich and full throttle. What you see at about 50' is what you want to see all the way. You can keep adjusting your mixture to achieve that target, but don't lean it further without closing the throttle, or you risk detonation. Of course if you are taking off from 5000' you are going to be too rich right from the start and it would be possible to run at max throttle for a short time ad lean till you get max rpm. I definitely suggest leaning when taxying, but lean it back until the motor won't respond to throttle, just to prevent you taking off too lean. I found that ssaved me from getting fouled plugs in my O-320.

    Thhe gauges on my RV4 were unreliable when full or near empty, due to the shape of the wing tanks. I fitted a red cube flow meter which gave very reliable flow measurements plus it gave fuel used. Could be reset to full at any top up, or the actual figure could be put in. No use of course if you get a leak before the actual meter, but better than the gauges.

    When I saw the heading for this I read it as faux, instead of Raus, does this imply anything?

    Registering with AMSA is an easy and painless job. I have always found them very helpful. I used to swap mine between two aeroplanes and bushwalking.

    Glen. I cannot think of any aircraft such as you describe,, where CofG limits are 100mm at 500kg and 1mm at 600kg. Is there such an aircraft? I am wondering if this is a real situation that I have no knowledge of, or is it something someone has said without proof? It is certainly necessary to ensure that the attitude of the plane is correct when weighing it. My Corby is well within C of g limits, but if I pick up the tail by hand and lift it to abour 1.6m height, the plane will tip forwards if I let go. This leads to the tongue in cheek question. If I am in a steep dive does my Cof G move forward?

    I didn't find the time to watch Paul, but he usually talks sense. Current thinking in the USA is that the ELLT hasn't really worked for years. A PLB or a mobile phone will work better and ADSB is way better. FAA may drop the requirement for an ELT to be fitted to every aircraft. Our situation is that CASA will allow a PLB to be used as a substitute in experimental aircraft.

    I read what MM said in Australian Flying ans it appears that all he is interested in is getting a higher weight limit. Higher limit means more planes eligible, which means more income for RAAus. MM becomes leader of an even bigger empire. More members equals more voters to not be interested in what they vote for.

    Reading here it appears that RAAus do not have a standard of competence for understanding W & B. I thought that there must be instructin and testing on that as part of the curriculum to get a pilots certificate. I don't recall ever seeing changes to acceptable C of G with changes of gross weight. I certainly cannot think why it would be necessary. The gross weight has to be within limits and the C of G has to be within limits. If either one is out of limits, the plane is not airworthy, there is one trap often missed by pilots and that is C of G moving during flight due to fuel consumption. The friend who I mentioned earlier could have had that happen, as the fuel tanks are to the rear. He tells me that he checked W and B and as he also tells me he worked as an aeronautical engineer with De Haviland, I assumed he had some idea of what could go wrong.

    If Nomad can't afford the membership I cannot see how he can afford to fly at all. The membership would equate to one hours flying I would guess, so at best he could afford one hour a year if RAAus fees were zero. Sad but that is what happens if you don't have money. Personally I afford the money to fly and forgo coffees and meals out.

    i had not realised that Schutt was using the walmart principle when I did a fair bit of my training with them. I must say that they were the most professional and competent training school that I flew with. Latrobe valley Aero Club were next in my opinion and some others hardly rated at all. When I got involved with Ultralight flying I was appalled at the poor standards of training, except for one CFI working on his own. I was very lucky not to be paying the ultra high prices that seem to be the going rate nowadays.

    You should recognise carby ice, but how many didn't and have paid the price. Years ago I used to hire a C150 which had carbie ice if there was a cloud in the clear summer sky. I recognised it, but later a student pilot put it into the ocean, with no apparent faults that could be proved.

    That is what I am seeing and that is why I raised the question. Concerning test pilots it is good to be able to realise that you are a test pilot, far better than to find out by not knowing what you are doing.

    Why the class 2 medical for an RAAus licence? The remainder seem to be at GA, VH reg prices, but all you get at the end is an RAAus cert with X country endorsement.

    Welcome Jack. You have started off a rant about National Parks. In Aus they are different from US and also Uk. In the UK you can live and work in a National Park, run a farm for example. Not sure about in USA. In Australia or specifically Qld it seems Nat Parks are for the shutting up of anything not native to Australia, for example excluding honey bees and Brumbies, but allowing weeds free range for example Lantana. For those things they recognise as pests, such as pigs it seems to be do a half hearted attempt to control, then give up. Am I correct in assuming you are back in Arizona?

    Do RAAus have any requirement for its pilots to understand and be able to work out C of G weight and balance. A friend today who flies a high wing plastic fantastic RAAus plane asked me about C of G. He had taken a heavy friend flying and when he came in to land he couldn't get enough up elevator and landed nose down. No damage he thinks. He asked me if the regulations allow him to get the elevator settings changed. I cannot remember exactly what his plane is, but the Aussie agent is in Melbourne. He commented that he has never been able to get a stall, full up elevator and closed throttle results in a high rate of descent. The plane is LSA, so I told him it probably wouldn't be possible to alter anything, but he ought to check the actual deflection of the elevator. The pilot and passenger sit forward and fuel is further aft, as is luggage. Must find out what the plane is

    the vacuum gauge I meant is a gauge measuring the drop in pressure in the carbie throat, which is really the same as a manifold pressure gauge, except that a higher reading is a lower pressure. In the good old days a competent mechanic could use a vacuum gauge as a diagnostic tool for engine tuning. I still have one although I don't have a petrol engine to use it on. My transport and tractor are compression ignition.

    I think the alternative organisation is not going to happen. Talking to the people involved last year one of them was muttering about taking CASA to court. That would not solve anything as CASA has very deep pockets. One of those involved now has a position in SAAA and the whole scene is extremely quiet.

    It looks to me like a case of showing off, been there , done that, but I never tried to include an aileron roll.

    There is no way you will fly direct from Canberra to Latrobe Valley. A large part of that route is in "Designated remote area" Whichever way you go it will be long and convoluted. Start planning by looking at where the remote area is, then the restricted areas you have to steer clear of and the controlled areas or military areas. Then you can pick a route and keep refining it until you are happy with it, but it is not going to be 204 deg, 218 nm.

    Does it get the max speed up over the cruise, approach, glide speed of 50Kts?

    The Bing carbie used by Jabiru has push on hose fuel lines with Jubilee clips. Not the best but I have lived with it for 18 years. Better is screwed fittings, such as the AN stuff and only have flexible hose where it is needed. There is a difference between an oil fire and a fuel fire. I had the thread on the rocker cover give way on my original Jab 1600 engine. Result a lot of whitish, grey smoke, just after I turned crosswind, which quickly reduced in volume. I had time to work out what was causing the smoke and was easily able to make a safe landing. That was flight No 3 on my test flying program and the decider to overhaul the second hand engine.

    Wouldn't a small hole in the diaphragm mean that the pressure above the diaphragm would be less, resulting in the piston not lifting and less fuel being delivered than required.

    Michael Monk could be the best of the candidates, I don't know, but from what I have seen of him he views the RAAus with rose tinted glasses. He didn't impress me face to face.

    Wasn't it Greece that refused to let US planes use their airstrips to bomb somewhere in the middle east and A US general commented. Who do they think they are, they are a democracy for gods sake. That tells me that the US definition of democracy is "pro USA".
