    Kangaroos Attack Aircraft With Stinger Missiles

    Depends what sort of things you like. Aviation things to do all year round. As for beaches: stay away from the northern beaches to avoid crocs and stingers. My favourite beaches are Torquay (Vic) in the summer and the Sunshine Coast (Qld) all year round. My favourite!

    Kangaroos Attack Aircraft With Stinger Missiles

    Just to clarify: Expect to pay $12-13 for 6 common beers. (When our dollar eventually returns to the long term average it will be very cheap for you.) We generally do not export our good beers (or wine). Most things in Australia can kill a person but they generally don't hunt you like some of...

    upset recovery training

    I couldn't recommend one over any others as I only know one personally but I would certainly recommend Dagmar Kress to anyone. I'll be there next month.

    Hammerheads

    Been years since I have done hammerheads (stall turns) in a Chippie or Tiger Moth so just a general comment that a big aeroplane with more inertia and low power so low power to weight ratio means that at low speeds the power effects are less significant. I regularly teach hammerheads to left...

    Half Snaps

    Yours are much neater than my practice earlier in the year http://www.youtube.com/watch?v=0cGCHldWjGY&feature=youtube_gdata A bit better for the contest this month. Vertical half snaps work fine but then I am not being judged when I do them.

    Snap Roll(s) Question?

    Consider a full snap - halfway round you will be off the original heading but back to it after the full rotation. Stopping it halfway results in you finishing off heading. Some refinements to minimise that amount but think about: as soon as the snap has stopped - boot the other rudder to slide...

    America's Vintage aircraft are being crated up and shipped overseas

    This is one of the most popular aviation mags in Oz: http://www.yaffa.com.au/cmag/fph.html There was a long period when only British aircraft were imported then Cessnas and Pipers started coming in - mid '60s. For many years the choices were largely limited to Austers, Tiger Moths or...

    America's Vintage aircraft are being crated up and shipped overseas

    My friends have got some very nice airplanes recently - don't worry, the vintage ones have all gone to good homes. I got a '74 Pitts S-2A that was once Marion Cole's apparently. A friend got a near-new Pitts S-2C. Keep the Skycatchers.

    2013 IAC Advanced Known Video

    Good idea, I will do some for the IAC as well as the AAC over the summer holidays.

    2013 IAC Advanced Known Video

    not to mention some Unknowns I have seen recently. This has inspired me to have a go at the 2013 CIVA Intermediate/Yak52 Known in my S-2A.

    US to New Zealand... how?

    Across the Pacific you will get to see a lot of water. Across the top of the Pacific is (or was, not sure of political situation now) doable. As would be going the long way round - I'd suggest professional flight planning services to organise the approvals and advise on bribes etc along the way...

    Streak Eagle- Time to Climb

    http://aerade.cranfield.ac.uk/subject-listing/esdu/ES1834.html for an overview of the energy height method for flight path optimisation. Do it for a typical GA airplane and would be pretty much a simple Vy climb.

    Robin DR2160

    Now you know how we feel getting parts for American aeroplanes sent to Oz. The Robin (or the newer Alphas) are quite popular here. I can't think of any reason not to buy one.

    Dutch Roll

    Thanks FlySince9. From memory the natural frequency of the 172's DR is much higher and I would've expected a majority of yaw in it so let's not call it a DR. As others have suggested, the operator may not have been bothered but your info should've enabled the cause to be found. Things don't...

    Dutch Roll

    In general, the thing that reduces damping of the Dutch Roll mode of oscillation with a swept wing is the same as a wing with a lot of dihedral. So, a straight wing with too much dihedral will exhibit Dutch Roll - I regularly fly one such type. As for this 172, I don't know whether I have...

    Spins

    I generally agree with you however: - certification requirements for intentional spinning is the same whether the airplane is in utility or aerobatic category - the standard statement in flight manuals about "slow deceleration" is not a limitation of the approval It's times like this when...

    Spin recovery

    Extracts from some magazine articles as discussion points: 1. Sport Aerobatics Magazine December 1986 Spinoffs Part 3 by Gene Beggs. "Incidentally, you should remember that when performing either upright or inverted flat spins in the Pitts and Eaglle aircraft using full power, you must be...
