    "PDPs"? Pretty damn private?

    Bruce,. It may be easier than you think (don't overthink). Go and talk to a flying school, which will tell you what their process is to get you over the line (go and talk to a few of them - starting with the one that hates Jabs so that it will get easier - then have a holiday in Albany as I understand the CFI there is a good bloke). The only things which you won't have done is under the hood, CTA procedures, a medical and a flight review, which might be at a higher level. You will need a transponder for Class C.

    Australia was unable to use the Mirage in Vietnam because of French interference. There might be financial and engineering penalties in establishing an Australian defence industry but Australia is a long way from anywhere else and well provisioned defence forces and diplomacy are essential. Killing off defence industries or giving them boom to bust conditions, like they currently go through, is pretty stupid.

    Instead of just hours, RAA should record and publish take off and landing statistics. After all 90% of the trip is in the first and last 5 minutes. Ultra light pilots get much more excitement in those 10 minutes than jumbo pilots get in 12 hours (apart from Russian Scuds). I would estimate that a Jabiru engine gets much more excitement than any other engine, given the numbers doing circuits in training.

    Some things take time to show up. Is there a test for mad cow disease in blood? Some things take time to work through the system and you need info trails to chase down those affected. You can, with a lot of expense, recreate plans and drawings for a dam or refinery but not for the clients of bad medicine.

    The maps only show sources on line, not power available. Coal fired stations are very hard to put on and take off line and their pricing model might be that it is more economical to give the power away than to depower the station.

    The back up for wind is the windfarm on the other side of the hill (brought to you by the power of networking and smart engineering). The farmer may get paid rent for the land where the tower is but the wind farm operator only gets paid when power is being generated and placed on the grid. Turbulence? Bugger all. Navigation Hazzard - what you can see can alert you to where you are. My complaint about the grid is that they can be hard to see. I would like the power people to paint the tops Orange so I have an alternate to roads and rail for navigation

    Ah, mea.culpa (as Gough would say). Capitalism is the Govt. giving money or forgiving tax only to the big end of town.
  9. coljones
    As evidenced by some recent enquiries, that is precisely how Capitalism works.

    An opinion piece about an opinion piece (probably about an opinion piece) - what has this to do with aviation?

    Somewhere, out there is a square. On one corner you have Abbott and the Rabbids, another you have the Lord will provides, another you have a very puce-faced Turnbull and on the final corner you have (the quite reasonable, fair-minded, honest) green power supporter. Is the solution anywhere inside this square?We should move this over to the other site and get your 737 out of the picture.

    There are times, Ron, when wind turbines are spinning uselessly because there is no demand, when no-one is cooking or running A/C in Summer or heating in winter. (Ignoring of course expensive aluminium smelting). There are also time when users don't consume expected power being produced by coal fired stations which can't be turned off instantaneously. All this surplus power can be used to operate water storage systems with energy available on a quick release basis to the network.

    QNH is the pressure. Temperature affects density with pressure remaining constant. If you heat up a pan of molasses the pressure at the bottom of the saucepan will remain constant but the mollasses will expand, become less dense and less viscous. Things that used to float in cold mollasses will now tend to sink. When the density of air decreases things that used to float, like an aeroplane, will now tend to fall and will need more power to stay afloat. An everyday example of this is an Archimedes thermometer where the floaty things depend for their position on the density of the fluid which depends on the temperature. An Altimeter with QNH correctly set will tell you how high you are. Density altitude tells you how well you will fly (if at all) and how long it will take you to take off (if you can). Most performance charts will make take off and landing distance calculations easy for you. A high and hot day can bugger up your plans.

    Burning anything in a small room is bad for anyone's health - that includes any unflued fire including those depending upon coal, which is probably worse than dung because of the presence of toxic tars and Radon gas. Occupational and Environmental Causes of Lung Cancer

    "State sponsored endeavour"? Hasn't anyone mentioned the banks and energy companies to you recently?

    Were the bags surplus to requirements (and not worth pulling out of the roof space) or are there holes in the insulation where they should have been placed?

    Number 4 is Young, NSW

    Number 2 is Orange NSW - I cheated, I flew there on Sunday (but no $100 hamburgers in sight)

    Lightning Ridge?

    Talking like that will have the frogs coming over and blowing up your tinny.

    No, they buy renewable power in from adjacent and not so adjacent countries and regions where the wind is blowing. The Europeans know all about power networks and their efficient use.
  23. coljones
    What the politicians don't or won't understand is that the wind is always blowing somewhere and that what is required to have power everywhere is to have a power network to move power around as required. The Liberals in SA sold off the power stations and it was Alinta that closed down the coal power station at Port Augusta. The greatest problem with power is that those making the greatest noise have no clothes.

    59 messages on this discussion and no-one has bagged Jabirus.

    And of course those regularly done over by non government action. Financial gurus are causing a lot more damage than governments ever have. They are the modern version of the squatters.
