    I have been one of those who think airline pilots abilities are not up to scratch in some places. There have been several crashes when it was apparent that the crew were not competent. Airbus tried to prevent this by trying to make the pilot redundant, but they still had problems. Boeing tried to cut corners and make themselves more affordable by not getting pilots trained correctly. I used to consider Boeing safer to fly in as a passenger, but not now. I also find that Airbus are better for the passenger, being quieter and as far as I have found, more spacious. I would fly in either Airbus or Boeing, but not with some airlines and especially not an Indonesian line nor Thai.

    The only Gazelle I have flown was GA reg VH-ROK, owned by Rockhampton aero club.

    The Thruster is not that difficult to fly, but you must be aware of what you are doing. I have heard that you must wheel a Thruster on and that it will stall if you don't get the stick forward if the engine fails. I hated wheeling my Thruster on and felt I had much more control three pointing it. I laso never had a problem with stalling. It was practically stall proof, just used to waffle along and you could keep a wing up with rudder. The Gazelle I would agree is the easiest, but its sibling the Skyfox was nowhere so forgiving.

    I fitted a Red Cube to my RV4. Got it from Steinair in USA. Worked well with the MGL instrument which was in place.

    I doubt it is fuel level causing the problem as Jabs will run several minutes at low rpm with the fuel turned off. I like the idea of using a timing light to see if you are getting a spark. I just had one coil stop working for a couple of minutes on startup, then it came good. One dud coil and a failing one could give the symptoms you describe. If you have a multimeter handy you could do a quick check of the coils as described by Jabiru. Just check resistance of P lead connection to the body of the coil, which should be 0.8 1.0 Ohms and P lead connectiion to HTlead at distributor, which should be 5.9 to 7.1 K Ohms.

    I cannot find the instructions for sightseeing at Ayers Rock, but from memory there was one direction to go round, same at the Olgas. The whole area was in a designated remote area and if you didn't have HF you had to stay within sight of the main highways or railway lines I have a 1994 VTC for the Alice and Darwin. This gives VFR routes to several places in the area and shows the route to Ayers rock going overMulga Dam and Lawrence Gorge check points. In those days a lot of aircraft had radios which had to have the necessary crystals for the frequencies fitted. I am not sure when the modern multi frequency radios came int being, but it was around the time you are interested in.

    The Cirrus pilot overshot his runway and must have crossed the metroliner at nearly 90 degrees. That the metroliner could lose half of its cabin diameter and still not fall apart is amazing. All the loads rom the elevator would have been in that remaining section of the fuselage.

    Nothing wrong with my tiny tach except that it keeps reverting to one pulse per revo;ution. All I need to do is divide indicated rpm by 2 which is easy. I still have the tiny tach installed and have fixed the problem, which was a failing ignition coil. Today I started the engine and no rpm on tiny tach as before. Turned of L mag and engine ran OK, turned off R mag and engine stopped. That just verified what the problem was. Replaced L coil and all works well.

    From what I have seen all choppers seem to think they are not included in the rules. They also don't seem to have been included when brains were handed out, or at least some of them don't.

    Can the airservices radar spot my Corby flying at whatever altitude and know what that altitude is? I doubt it, I even doubt that they would spot it at all at less than 5000' That means that if they bring in the 4500' E level, they will never know if I am in or out of it. It only remains for me to stray a bit high and there is the possibility that they cannot warn me or others of my presence in class E.

    a pen name. What you seem to be saying in a lot of words is that you get better at flying the more you do of it. I think we would all agree, but you get better at flying a Gazelle a lot sooner than flying a Thruster, or a Cessna 310

    RF you are just about correct. I have a replacement coil ready to fit nd that should fix the problem.

    Not a broken sensor wire. If that was the case I would not have got a reading after running for a while/

    You don't need an ASIC for GA, but if you don't have one you need an MSIC I think it is called. A grey card which costs less. That is so you can be recognised. I used to have a PPL with my photo on it in pre ASIC days. It does cause a need for more bureaucrats and also raises money, plus the government considers anything which adds to GDP is good. Such things as more prison spending or cleaning up rubbish, even more people engaged in road traffic control are good for government.

    This compliance with ICAO requirements is rubbish. Airservices will use that as a reason and then they will admit that it doesn't comply with ICAO but is purely Australian. Been there done that. Use any argument to bolster your aims, even if it is rubbish.

    I don't know for sure if replacing an 80 hp Rotax with a 100 hp Rotax would need re registration. If it was GA there would be a requirement to do test flying of the new engine for a prescribed number of hours, also a re weighing for W & B.

    I know the problem with the info I posted here. The fix is under way, I just wondered if others could spot what the problem is?

    It is the home of MGL instrumentation.

    Looking back at history I think you could say that USA was anti semitic before the war. It was only Hitlers actions that made Judaism something to hold up as fine and good. Israel is working hard to turn that view around, but once the Yanks have something to glorify it takes a lot to change their mind.

    A Corby would be way cheaper than a plastic fantastic RAAus aircraft, even if it was GA reg and most of them are. Some of the accident reports from airline crashes make me wonder if those pilots are capable of flying. There are reports of pilots asking each other "What i it doing now?" as they are crashing, or not being able to tell that their airspeed is high, even though the nose is way below the horizon according to their instruments. I know this is a very small proportion, but it really worries me that airline pilots can be so unable to work out what is happening. There are also many cowboys in GA flying and sadly they often take someone else with them when they exceed their self professed expert capabilities. From what I read here there are some RAAus pilots who seem to be lacking in theory knowledge, but they may be perfectly capable pilots.

    I am grounded at the moment due to letting my BFR expire, now I wait for an instructor to call by. Today I decided to run the engine to get a bit of oil circulated. Compressions were really good when I pulled it through. I have had a bit of trouble with the tiny tach, which reads of an ignition lead. Just a few coils of wire around the lead and it induces a current which the tach reads and counts. Problem is the tach keeps re setting to one pulse per revolution instead of two. Not really a problem as I can tell if it is idling at 1000 rpm or 2000. Today when I started up the tach was dead, no rpm at all, just a blank screen. Not a problem as I was not going flying, then suddenly it came alive, reading at twice the real revs. I thought I would pose what happened as a problem for you. My first thought was that the tiny tach had failed completely, but as it came good, I thought an intermittent fault was probable. I did a mag check and running on the left mag there was very little mag drop, running on the right mag there was some roughness and the tach went blank, but that is normal as the pickup is on the left mag HT wire.

    Vans stress that you need to watch the speed, especially as VNE is a true airspeed. That means that at height and on hot days TAS can be way higher than indicated on the ASI. Something you have to be aware of when test flying your new aircraft. I took my RV4 to VNE during the test phase, but I was using an ASI that calculated TAS, even so it could have been slightly off compared to a worked out TAS.

    Looking on Vans site they have posted the preliminary report, which says nothing really, but it is suggested on Vans site that the RV7A should have the same rudder as the RV8, instead of the one supplied in the kits. This would give greater strength and help with flutter or excessive loading. I am not aware of what the difference is. By Vans site I mean Vansaircraft forums.

    I agree with the reducing of throttle, but my next action would be to centre the ball, followed by aileron to bring to level and control speed with elevator.

    If heat does not travel to the venturi the moisture in the air will turn to ice and this is what carbie heat is there to prevent. Heating the reduced amount of air and fuel that has got past the ice in the venturi is not going to do any good at all, in fact it will reduce the density.
