  1. Would the moderator(s) please delete every reply that is not immediately relevant to the accident in question to save server bandwidth and reader frustration please? This thread isn't drifting, it's moving away from the subject at Mach 1.2! Back to the subject, I met the pilot in question at Wollongong the day he undertook the ill-fated flight and am very saddened to learn he did not make it home. We must wait until the investigators have done their work before we go speculating on what might have caused the accident. We have lost a fellow-aviator and that ought to make us pause and reflect
  2. According to reports of ATSB assistance for the ASRA investigation of the gyro accident, it was a separation of the upper part of the mast from the gyro. (The gyro in question was fitted with the folding-mast option.) The instructor who lost his life was 60-year old Mike Waldon, from Kiama. Mike was a friend and colleague, a very good instructor and meticulous about pre-flight inspections. I miss his humour, professionalism and determination. He was one of a kind. Condolences to his family, especially Caitlin and Alexia.
  3. Repeat the test in a wind-tunnel with the airflow over the wing at normal cruising-speed for a better test of a real-world situation. Either way I think there will be significant wing-damage. As for the drone...
  4. One if those killed in the gyro was a personal friend and aviation colleague. RIP my friend, you will be missed.
  5. APF Interim Fatality Report now issued. Situation is a little more complex - and baffling - than I described above. A freefall collison appears likely, but canopies did open; the tandem reserve canopy and both the main and reserve for the solo jumper. Severe injuries to the two jumpers consistent with freefall collision, but the solo jumper also descended to the ground under a "down-plane" at a high rate of descent which may have contributed to his demise. Tandem pair located at the base of a tree with severe injuries and pronounced dead at scene. This is a very complex accident and the inv
  6. Collision in freefall apparently. Tandem-Master and Camerman both knocked unconscious, camerman's AAD did not activate, he became tangled in the tandem drogue-bridle, the tandem AAD activated but the reserve became tangled with drogue-bridle etc and all three died. Heavy blow for the skydiving fraternity so soon after the double fatality at Picton in July.
  7. The maximum bank-angle for a turn in the circuit (be it crosswind, downwind, base or final) shoud be no more than 30 degrees on any trike wing, be it Wizard, Arrow, P&M Blade or whatever your trike-wing is. For most normal flying away from the circuit a 15-degree banked turn is quite sufficient. I teach the 60-degree banked turn as an emergency avoiding-manoeuvre only, using added engine-power to counteract the potential height-loss due to load-factor, and stressing the need for a gentle recovery to prevent overspeeding as a result of conservation of angular momentum. Anyone needing
  8. Here's a trick for flying in rain in Jabirus with wooden props if you simply can't get away from it. Reduce your airspeed below Vfe, then lower half-flap. Now set engine RPM to keep you level at 70KIAS in the J160, 65KIAS in the 170 or 230. In the J160 this is about 2400RPM with half-flap and 2 people onboard. Maintain level flight with elevator. This will take 500RPM (approx) off your prop and greatly reduce the impact of raindrops on the leading-edge, whilst maintaining your chosen altitude. Once clear of the rain, retract flaps and increase power to normal cruise-settings.
  9. Various BBSs have something like a "Gone Home" or "Departed Friends" section. Bandwidth and storage are potential issues as any BBS expands.
  10. "Kalganyi", private strip immediately adjacent to Hume Hwy south of Marulan. Grass surface, faces E-W. Good surface, slopes at either end, more gentle slope to the west.
  11. The pilot has a history. This isn't the first time ambition has exceeded ability. If he never leaves the ground again except in an elevator I will be very pleased.
  12. You may as well ask why aviation, shipping and the scientific and business worlds still use English - because no-one's come up with anything that works better and which people are prepared to adopt. It works, that's why. The Germans persisted with units of angular measure called "grads" in which there were 100 grad in a right-angle and four hundred grads in a circle. Try buying a sextant, or a set-square, or a protractor, or a goniometer calibrated in grads these days (if you can still find a sextant for sale, that is.)
  13. This is gutting. Ross was a colleague and friend back in the skydiving days at Wilton in the early 70s. His passion for sport aviation was evident then, and he never lost it. He survived the crash of a fully-loaded jump-aircraft and although it affected him deeply, he still retained his love of jumping. He was Alan Jay's rigger when Alan was building the "Parasport" equipment, some of the very first custom-built skydiving gear ever seen in Australia. He had seen so much and knew so much in sport avation he became a touchstone, a resource from whom a great many benefitted time and time again.
  14. Weightshift:- fly the wing. 3-Axis - fly the wing. Start flying the wing and stop just flying the controls. Works every time! A wing only knows how to make lift. It doesn't know what it's bolted onto. Make the wing do the work, and fly it and only it. That way, if you don't break the wing you probably won't break anything else either, and if you make the wing go where you want it to go the rest ot the aeroplane will follow. Fly the wing.
