    I've only 1 single hour of tuition in an R22, but was told by the instructor that you have literally a second or so to drop the collective on an engine out in the R22, the rotor inertia being so low.

    Apparently the R44 is a little more forgiving

    Coincidently I was watching an R44 doing practice autorotations today at Berrow and it all looked quite relaxed, but of course thats no indication of what was going on in the cockpit

    A local R22 owner pilot told me you have 0.3 seconds to react to power failure. Different instructor?

    Years ago when I assisted taking the wings off a Savannah Bingo that hit treetops on take-off and crashed had heaps of plastic 2 litre milk bottles (empty of course) in the wings in case of a water ditching.

    The Savannah ditching at Conway Beach had the problem that the doors would not open until the cabin nearly filled with water to equalise the water pressure. The plastic bottles would have been much more use than deflated air matresses, the blowing time had nearly elapsed by the time they got out of the cabin.

    Sorry. I should cite my sources 🙂 BTW 90% is an approximation for the initial survivability.

    Nicely played! Troll proof.

    The speed will be projected speed along track NOT airspeed which we are used to seeing. A near vertical dive would register low as you don't progress along the surface much.  Nev

    So 313 knots projected on the flight radar track may have been two and a half times that given the sudden altitude loss that is accompanied?  That being the case, why would you fly on for your destination rather than divert to Roma or return to Toowoomba?

    Strong possibility. Any plane subject to severe overload or a hard landing has to have inspections of relevant parts of the structure. or get a permit to fly (No pax) to a place where it can be done. You'd have to be very lucky to get one for that  AIRCRAFT in those circumstances Limping might not be the best word as it flew normal speed and levels till something happened.   Nev

    The something happened north of Dulacca much nearer to Toowoomba than to Mount Isa, which may have been a better place to limp to. While they reacted to the something, they maintained near perfect track while losing a whole heap of altitude and airspeed rising over 300 knots.

    It looks as though it's had an "UPSET" earlier in the Fight that exceeded a lot of limits and resulted in total failure later (as well it would).   Nev

    Its logged speed was over 260knots but it didn't seem to exceed 223 in the later part of its final flight. Are you suggesting that it was limping to its destination?

    This article shows a photo of the wreckage. Would be interesting to know it the under carriage inverted during the ditching or the recovery. I could also have impacted the ability to open the doors inverted like that.

  8. I saw about 8 cropdusters working between Boomi and Boggabilla yesterday. It was quite remarkable that half the country was underwater and the rest was highly developed irrigation diverting flood water, business as usual. Two working at 90 degrees to each other, when their runs coincided, turned into the same space. Must have been uncomfortable even for the pros!
