    if i was going to buy for a flying school, N# 1 on the list would be the Brumby. well built, rotax or even lycoming reliability.

    remember stall is a function of AoA. nothing more.

    yep, i have a set of lightspeeds, had them for years, worn out the ear seals, as well as the padded bit over your head, they still work fine, also great is the bluetooth music and phone when in use. great for calling up AWIS when a long way out. organising fuel, etc. music helps with the long legs

    i would say 50% to insurance companies 40% to the government in the form of regulatory compliances and taxes, the last 10% to be spread between suppliers, fuel, manufacturers and general business expenses.

    What technique do glider pilots use? i use that one... only 1 instrument required... airspeed.

    carby ice can form in a few places, mostly the throttle butterfly valve, but also in the sides of the induction system just downstream fuel jet, the ice is formed when the pressure drop at the venturi causes a temperature drop, and any moisture in the air will condense out and form ice. temperate drop can be enough to allow ice to form with air up to and over 30 deg C! if the moisture content is high.

    bugger the ice, i want to paint the entire underside of the Savannah with that stuff! i hate cleaning under there..

    during my time at a big Aussie airline, it wasnt uncommon to repair small holes and dents in the lower fuselage that look suspiciously like bullet holes.

    when i mentioned it floods, and the change of zoning will allow building, i still dont see it happening, as unlike other built on floodplains, that flood once every 25 or more years, the land around Jaspers Brush floods quite a few times Every year...

    to add a litle more info, the land the airfield sits on can never be developed, as it is a floodplain, that floods quite a few times every year. it cannot be developed out, it can only be used as it is now, recreational airstrip/paddock for cattle and the occasional duck armada. there is no other reason to shut the place down other than to appease a very vocal small group of whingers.

    the name Sonja isnt mentioned anywhere is it?
  14. Ultralights
    pure factual information on that page......

    Sadly the music was added by youtube, something about copyright or sum such nonsense about the Aussie artist music i used. sadly, no slow version as its a made from single still images taken every 2 seconds, so if you slow it down, just starts to look like a really fast jerky slideshow.

    for both to fail at exactly the same time, sounds either extremely unlucky, or something has been dont to cause the failure
  17. Ultralights
    like this?
  18. Ultralights
    Was it over 38 deg C?
  19. Ultralights
    sadly, Not many people file a incident report regarding most failures, just send the engine off, deal with the manufacturer, and get it fixed, no reporting means no data!

    these litte rubber thingies jam it in after its clipped in, it reduces vibration and reduces noises from the mount
  21. Ultralights
    Jabirus have a high survivability in an off field landing due to the strength of the airframes, nothing to do with the engine. The engine just determines how often you might have to test that airframe.
  22. Ultralights
    The wavy effect is from vibrations matching the frame scroll rate, did you use the little rubber thingies that come with the camera?

    When the Spot is activated its sent through the USA and global rescue agencies, using the American and European search satellite network who then forward all information and work with the Australian SAR
  24. Ultralights
    sadly most untrained witnesses see a low flying aircraft, its always on fire, or has a sputtering engine. as for the SPOT, i have one, and its comforting knowing its leaving a breadcrumb trail wherever im flying, so even if i dont activate the SOS function, the SAR services already have a small search area and can pretty accurately predict where i should be. sadly, they are not CASA approved. My condolences to all involved.

    38 deg C temp limit is for composite airframes? What a load of ....... so, what happens to the 787, 747,767,737, Airbus A330,A320,A340,A380 aircraft, all the gliders, Grob aircraft, and countless other airframes that sit parked in hangars and operate in environs far hotter than 38 deg C? what about all those composite engine cowls wrapped around countless Lycoming, continental, rotax, Rolls Royce GE and Pratt and whitney turbine engines? dont forgedt the internal core cowls that sit at temps well above 100 deg for trips across the pacific every day? all those composite F18s sitting and flying around the deserts of the middle east? by they way, my specialty is Composite airframe structures..... that limit is just a Jabiru excuse. their airframes can handle well over 38 deg C, if they used the cheapest lowest rated epoxy resins, then the maximum will be 70 deg C. unless of course, Jabiru dont use Milspec or aviation grade epoxy? hmmmmm
