    In New South Wales, the Dept of Fair Trading has been extremely helpful towards organisations wanting to associated under the relevant legislation. To assist those organisations adopt a constitution, the Dept. has gone through every paragraph of Act and written a draft constitution that covers every line of the Act. All an organisation has to do is run a "Find and Replace" through the template document to insert the organisation's name to make the an approved constitution. Since all the work was done by the Dept. there are no mistakes and it is accepted without review during the registration process. Things like the expulsion of members is dealt with, taking into account all natural Rights we expect to have.

    Keep egging them on for more!

    So true! So true. What does the Government do? Pour money into apprenticeships in the construction industry, but not a brass razoo into trades that keep things going. Virtually every sector of the aviation industry is dying due to practitioners reaching retirement age and no replacements coming on. Replace "aviation" with any other industry and it's the same story.

    This is an example of an oxymoron. One of the meanings of "sovereign" is acting independently and without outside interference. This meaning is usually applied to a Nation. Australia, we hope, is a sovereign nation. But since it interacts with other sovereign nations, those interactions affect is absolute independence. That a fish on a completely different bicycle. The commonly used meaning of "citizen" is a person who, by place of birth, nationality of one or both parents, or naturalization is granted full rights and responsibilities as a member of a nation or political community. So citizenship both implies and demands positive interaction with some governing body, even to the extent that the governing body might be a criminal gang. Citizen also has the meaning "an inhabitant of a particular town or city" which could be extended to include a geopolitical area - a citizen of New South Wales. So a person cannot act without independently and be a citizen at the same time.

    Imagine how far along we would be today if the Wright Brothers had not sold their patents to Big Business, which effectively stifled aeronautical advancement in the USA until 1920 when a parsimonious government set up a small organisation to advise on research. That was the National Advisory Committee on Aeronautics (NACA).

    Do you w ant me to send you a list of motels in Gilgandra where you can stay when you come to the Event in May?

    The only step forward I see that Lilienthal made was upper surface curvature of the wing. That was an important step and was the basis of the Wrights' research. Based on their measurements, the 1901 aircraft only developed 1/3 of the lift which was predicted by using the Lilienthal data. At the time of the Wright brothers, the reference conditions for the lift and drag was the drag on a one square foot flat plate moving at one mile per hour. Today we base our lift and drag coefficients on the dynamic pressure of the moving air. When the Wrights began to design the 1900 aircraft, they used values for the lift coefficient based on the work by Lilienthal. Lilienthal and the Wrights used the .005 value for the pressure factor. During the kite and glider experiments of 1900 and 1901, the brothers measured the performance of their aircraft. Neither aircraft performed as well as predicted by the lift equation. The 1901 aircraft had been designed to lift itself (100 pounds) plus a pilot (150 pounds) when flown as a kite in a 15 mile per hour wind at 5 degrees angle of attack. But in flight, it could barely lift itself in a 15 mile per hour wind at a much higher angle of attack. So the brothers began to doubt the .005 value for the Smeaton coefficient. They determined that a value of .0033 more closely approximated their flight data. They developed a system of measuring the forced of Lift and Drag, using a constant wind velocity generator (wind tunnel), and produced the results that enabled them to build winged machines that would rise above the ground if the speed of the air over the wings was sufficiently fast enough. Since they could not make a wind tunnel big enough for a man-carrying machine, they had to design their machine with the known wind speeds of Kittyhawk in mind. At the end of their 1901 wind tunnel tests, the Wright brothers had the most detailed data in the world for the design of aircraft wings. We tend to gloss over the actual work the Wrights put into making those first gliders. Their use of the Scientific Method virtually ensured them of success, at least in making a machine that would rise from the ground and remain airborne. Don't forget that in their early excursions off the ground the machine was tethered, simply relying on wind speed and wing design to keep it aloft, like a child's kite. This, no doubt, allowed these excursions to last much longer than any free-flight and, once they had twigged to the way to control roll, let them practice their control skills.

    Touche . There's a time and a place for fun flying and other for being damned serious. Carriage and use of radio was a great safety advance. The modern digital stuff is probably even greater. QUESTION: Can helicopters operating from a helicopter pad just buzz off anywhere they like, or do they have to fly in some sort of regulated pattern as fixed-wing aircraft do when landing and taking off from a runway?

    I reckon it would fly better if the tail was removed. It moves about too much and that must induce turning forces that are counter to the forces generated by the mainplanes.

    Now the cat is out of the bag! Now terrorists will know that if they arrive 2.5 hours before the RPT they won't need to produce an ASIC card. They can just hang around airside until they can put their nefarious plans into action.

    Bulk strip on the engine. Remove the CSU. Replace wing tip bows and recover the lot. $50 - $60,000 restoration bill?

    One thing I just remembered. Australian petrol is the worst in the world. It is of such poor quality that the European manufacturers of cars don't bother to wage major campaigns her to see their cars.

    Used to fly as navigator in a TriPacer out of Dubbo. It was also used as a glider tug at Narromine in the mid-70's. One thing I hate about Pipers in general is that there is only one door. I hated getting trampled by the evacuating pilot. Cessnas spoiled you with their independent toe brakes. There's one in need of a double helping of TLC at The Oaks. It's got a CSU, and wood rot. If wishes were .... you'd see an emu fly.

    That is most likely explained by the fact that Continental has only begun fitting hardened valve seats in recent years. Pre-2019 engines would not have them. What information do we have about ULP in Lycomings? But then again, when did Lycoming start fitting hardened valve seats? This Mogas/Avgas question has two prongs - the effect of removing TEL on exhaust valves and valve seats, and the effects of surface tension on evaporation of the liquid. The effect of removing TEL has long since been solved. Just look out at the traffic passing by. Almost all the petrol-powered light vehicles you see are using unleaded fuel. When I had the engine of my 80-year-old motorcycle reconditioned, I had hardened valve seats fitted and run it on 91 non-ethanol fuel. For aviation, the problem is the difference in surface tension between the two types of fuel. Surface tension determines how readily a molecule in a liquid will cross the boundary between the surface of the liquid and the atmosphere above. In general terms, a less dense liquid has a lower surface tension that a denser one. Mogas is less dense that Avgas, so it has a lower surface tension and will evaporate more readily when subjected to the same conditions of temperature and atmospheric pressure.

    The more people who insure with a particular company, the more the premium should come down. This is imply due to the fact that your premium is going into the pot to pay what claims arise. If ten people pay one dollar to cover a ten dollar risk for one year, then at the start of year 2, the pot contains $10 if there have been no claims. Therefore the insurer might be able to set the premium at 95 cents for year 2. The amount set as the premium is the insurer's odds that a claim won't be made.

    I've said it before. After the Robo Debt enquiry finishes, the whole Public Service should be examined to root out the culture of disservice to the Public.

    No. What I was meaning is that what SSCBD said about having a check to see if you could present the type of risk an ASIC clearance is meant to control should only cost a pittance, not the extortionist fee that is demanded now. Also, my Working with Children check lasts something like three to five years and is a Name and DOB check. So I agree that the ASIC system is an ineffective approach to security. And was there any need for the use of "Mr Plod"? Think about it next time you are the victim of crime. Or are you the vigilante type?

    A National Police check compares an individual’s details to determine if the details match previously recorded records within the National Police Reference System (NPRS). The results of the NPRS check are assessed by police personnel and a certificate issued. How much does a National Police Check cost? • Name and Date of birth check is $50.00 • Name, Date of birth and Fingerprint check is $197.20 • Volunteer working in Commonwealth Aged care only is $15.00 An additional fee of $5 is payable for applications which require a printed certificate to be mailed to the applicant. The Name and Date of birth check of a National Police Check is basically the same check that would be done if you were stopped for allegedly speeding and the constable decided to issue an infringement notice. That's what they are doing when they take your licence and go back to their vehicle. That check will provide your prior history of interactions with the legal system., whether as a victim of crime or an offender. It will also return to the constable any warnings that may indicate a penchant for doing bad things. I appreciate that this was written with humorous intent, but the inference offends me as career constable, as it infers a degree of bribery. Please don't use that anymore.

    If you can't fibreglass, go to a vehicle dismantler and pull one out of a car.

    New South Wales is a political unit on the east coast of the continent of Australia. It extends from the Port Hacking River in the south to the mouth of the Hawkesbury River in the north, and from the coastline in the east to the eastern bank of the Nepean River in the west. There is an extensive area beyond these bounds - a political No-Man's Land - that has tenuous ties to New South Wales.

    Batteries are the handiest things for adjusting CofG. Aircraft with tractor configurations often have their battery box at the rear of the fuselage to generate a Moment to offset the engine's Moment. That would help solve your access problem. The only downside is the cost of the extra length of power cable you'll need to run from the battery to the bus bar. As for the continued serviceability of your current battery, I put a new, wet cell battery in my bike in September 2020. Circumstances have prevented my using the bike more than a 100 kms since then. The battery is still quite OK. The usual reason that any battery gives up the ghost is depletion of the chemicals it contains to provide electrons. If the battery has been sitting there, not losing electrons, the level of chemicals won't have changed much. Some of the slippery little devils will have jumped off the +ve terminal into the atmosphere, but there will still be plenty staying inside the box.

    Well, the airport is being built on Badgery family land. July 18, 1914, was one of the most significant days in Australian aviation. It was the first flight of the first Australian-built aircraft. ­Andrew Delfosse Badgery was the first man to fly an Australian-made plane, which he built himself on the family farm at Badgerys Creek. Well, not quite so true. The plane was a Caudron Type 2B. Most likely he brought the plans for the airplane with him when he returned from Europe just before WW1. So the correct description is that it was the first made-in-Australia aeroplane. The Caudron Type B2 was a 1911 design. It is said that the Caudron brothers built only two, so Badgery must just have had the plans. The pictures show that he powered it with an Anzani 6-cylinder radial of 60 hp. COP THAT, RED!

    It could have been YNBW. The only other YNB* is Narrabri, "Y" being the identifier for Australia.
