  1. yeah, it was an R44, quite a nice one, we taxied out past them before they departed, when we arrived at YWOL 15 mins later, we were told it had crashed with the loss of the crew. quite a shocking and nauseating feeling really.

     

    also sadly, it came down right in front of the clubhouse witnessed by the usually crowd there as well as a few younger children..

     

    at the moment Andy, (motz) and Liz are quite shaken up and needing our support.

  2. By the simple fact there are plenty around is testament to their ease of build. Hopefully someone nearby might be building one, and you might be able to go and have a look at one in the process of being built.

     

     

  3. if on a limited budget, i would seriously look at a early Jabiru LSA. they perform well, 100Kts cruise! fun to fly, no corrosion issues, and cheap to maintain as nothing to seriously go wrong, except engine issues. basic bullet-proof little fun aircraft. . and all around the 30 to 40K mark.

     

     

  4. If the system above a hill is explained by Bernoulli's theorem then why is it that the windspeed closest to the ground - and subject to the greatest change in direction and presumably therefore distance travelled - is also generally lower than the windspeed higher above the hill? Bernoulli doesn't take into account friction or the fact that a symmetrical airfoil also produces lift (even flat ones like the tailplane on a J3)

    i think this might have something to do with Coriolis forces and surface friction.

     

     

  5. so, nothing really new here, air over the top is accelerated, looses pressure, only change from the conventional taught theory is it doesn't reach the trailing edge at the same time, but in fact earlier than air flowing under the wing. or is it the air flowing under is slowed more than initially believed?

     

     

  6. North West NSW to me covers the area from say Lightning ridge to Broken Hill. North east, well, Moree to the top corner tweed area. either area is ok, its about 5 hrs in the Savvy from Wollongong to Lightning ridge, 6 to Bourke. all non stop if you have a big enough bladder.

     

     

  7. Thats part of the reason i have started the same degree, in the second year now, though fortunately i have trades in aircraft maintenance discliplins as well as CPL. i am also fortunate in they my employer has encouraged me to complete the degree, so i may be more deployable in different areas of the company.

  8. Some here make it sound like VHS regoes never run out of fuel... I dont think I have ever flown a Cessna or piper with a truly accurate fuel gauge. Even with my ppl and cpl training, emphasis was cockpit gauges are a rough guide, the dipstick is the trues reading. Even 747's have dip sticks in each tank! It's not an RAAus problem, or a culture problem. It's an aviation problem, for every jabiru turned into a glider by tanks full of air syndrome, there is a commercial airliner that's done the same, and everything in between. It was only recently I witnessed a Cherokee run out of fuel in the circuit at bankstown. It never made the news. Now there could be the real problem.
