IMPROVEMENTS ACROSS THE BOARD
                                                       BY MIC HAEL LINKE, C EO

        INCE 2014, macro change has resulted in dramatic improve-
        ments in the accident rate, the financial stability and the govern-
        ance of RAAus.
    We have had improvements in the governance space with RAAus
now a company limited by guarantee with seven Directors responsible
for strategy and policy. We have implemented an overarching govern-
ance framework which is publicly available on our website.
    In terms of financial stability, the Board of Directors and I have made
significant changes to our business model to create sustainability and
ensure RAAus has a bright future. We still run a frugal budget, but
structural changes to our resources and service models have aided in
creating positive cash flows and a surplus budget.
    With regard to our accident rate, some headline figures are quite de-
monstrative of real improvements. In 2013, our rate of fatal accidents
per 100,000 hours was 5. In 2014 this rate had reduced to 2.65. Today
the rate runs at just over one fatality per 100,000 hours. The graph          guidance for decision making.

              T’S a story common to many of the European ultralight
              manufacturers.
                  Slovakian company, Tomark, began life making parts
        for other people. It earned its stripes engineering metal and
        composites for cars, then moved to aviation in the late 1990s.
             The company started design work on the Viper SD4 in
        2004, the first flight took place just two years later and the
        aircraft was offered for sale in Europe, primarily as a trainer
        for the French market and tow plane, in 2008. The company
        went through the exhausting and expensive process of get-
        ting approval for the US LSA market two years ago and is now
        offering the 600kgs max weight Viper to all comers. So far
                  its sold about 30 of them, not surprisingly, most in
                       Slovakia. The company was reported to be con-
                           sidering bolstering US sales by setting up a
                             factory in Texas.
“The fit and                       The Viper is metal, with aluminium
                                skin. Composite materials are used for

                              auxiliary spar. The short span ailerons
                            move on piano-type hinges, with slotted
                        flaps on the rest of the trailing edges. The low-
                    mounted horizontal tail is also of constant chord
            apart from a cut-out for rudder movement; the starboard
        elevator carries a flight adjustable trim tab. Fin and rudder
        are straight-edged, but swept.
             The aircraft can handle either an 80 or 100hp Rotax 912.
        The undercarriage legs are cantilevered springs. The main
        wheels and nosewheels are faired. The mains are fitted with
        hydraulic brakes; the nose has steering as an option. A ballis-
        tic parachute is also an option. It has a wide variety of choices
        for avionics (no point fitting it out with the latest nav stuff if
        it’s only going to go round and round the local area, is there?)
        and it does come with electric flaps, electric trim and optional
        autopilot.
             Tomark says the Viper SD4 is also one of the few planes in
        its category to have successfully passed elasticity tests on all
        its parts, the so-called flutter tests. It has also demonstrated
        spins as required by the EASA.
             Like nearly all European ultralights, the fit and finish of the
        Viper, as with the high winged version called the Skyper GT9,
        is superb. It’s not going to go across the country as quickly
        as some (with only 70 litres in the tanks) but it’s a roomy and
        comfortable machine for training or towing.
             Tomark is looking for an Australian distributor. For more

    WORLD WAR ONE
    Thousands of aircraft were built during the First World War, but basic re-
    search was limited. The Germans started to look critically at wing sections
    and Gottingen University found that thicker sections had better stalling
    characteristics, without a serious drag penalty. Their work resulted in the
    Fokker D VII with a thicker wing section, which caused the Allies consider-
    able grief when it came into use in 1918. After the war, there was a great
    surplus of unwanted aircraft. After a few years, the potential for high speed                                       Fig. 3

A trip into the wrong airspace
                                                               BY NEIL DE ARBERG

“A
             IRCRAFT approximately three miles north of Fernvale at
             3,500ft, this is Brisbane Central”.
                Moments passed. No one answered. Then a feeling of ‘oh no,
is that me?’ squeezed the gastric juices. I knew where I was alright, right
where Brisbane Central said I was. I knew that. The gastrics got worse.
    “Um, I think that’s us Pete”, I told my passenger. Pete looked at me with
the blank expression you give someone when they say they just saw Elvis.
    With an air of bewilderment, I called, “Brisbane Central, this is Sling
8515. Are you calling me?”
    “Switch to Amberley Approach on 126.2”, came the response.
    That seemed friendly enough, so I did. Nonetheless, I wondered why
they would be calling me.
    The Flight Lieutenant told me, in a nice way, that I had encroached on
RAAF Amberley air space. Really? I was in the process of turning north-east
to Dayboro. How could I be in their air space?
    Then, to my horror, he asked me to switch my transponder to a particu-
lar code. I’d done it in the Cessna with four buttons. This one only had one.
    “How do I do that?” I quietly asked, hoping he would ignore me because
I had no idea. He didn’t know either. After a couple of transmissions to
adjust the transponder, he gave up trying to help me. He told me to stay at
3,500ft and report when clear of CTA. Then, soon afterwards, he told me I
was clear of the CTA. Nice guy, I thought. Then he also asked for my phone
number and flying school. Uh oh. Is this going to finish nice?
    As I flew home, now OCTA, I checked my chart. There was that little
corner in the red circle but restrictions didn’t start until 8,500ft and I was

in your flight planning.” Oops, I hadn’t seen those, only the R625D
8500/FL210.
    “What about the transponder thing”, I asked which earned me
another look. Yep, I knew the hijacker code and the no radio code.                    An EFB is not a replacement for in-flight nav checks or pre-flight plan-
