  1. And nobody has proposed a reduction in training standards. The syllabus will remain the same.

    You could have fooled me:

     

    “RAA mandates 20hrs minimum to pilot certificate. Have a look at the Training manual for 3 axis and compare to the PPC syllabus and try and convince me they would take a similar time frame to complete. Most PPC pilots will be solo in 3-4 hours and suitably proficient for a PC in 10-12 hrs. The remaining time is often just flown off doing some circuit work or XC flights to make the 20.“ AK #52

     

    "a US PPC instructor was here for a visit and a comparison between our training regime and theirs discovered they was similar but they were able to gain a PC in 12 hrs. Our augument all along has been that 20 was too many as the syllabus can be covered in much less." AK #81

     

    "A good PPC student could make it through in 10-12hrs, an average student maybe as much as 15. An exceptional one less than 10. If we used the same reasoning as 3 axis the correct MINIMUM for a PPC would be in the 10-12 ballpark." AK #84

     

    That coupled with statements that PPCs can't stall etc. are what prompted me to post the facts out there in the flying world.

     

    Drop those statements and I don't have a problem.

     

    It does seem odd that an instructor needs to be physically supervised by a CFI, however no one has posted about the history, and why this has occurred. It may well have been that instruction was out of control and someone made a permanent decision to modify their behaviour, but screwed up by making it a permanent change. This is where Certificate IV which includes both training a student, and being qualified to assess that the student has absorbed the training provides the full protocol to allow an Instructor to operate without hour by hour supervision. Maybe there's just an error there that needs to be corrected.

     

     

  2. A paraglider wing is designed to be manipulated in the air to reduce surface area, change shape and angle of attack. This is completely different to a PPC wing which is not. With the exception of the Excitor which you can change angle of attack by a couple of degrees.I guess your change to the phrase pendulum aircraft was to cover your mistake. If you build any aircraft with a wing AofA different to what it was designed for just to gain some speed do you think it makes all of them unsafe. Even the ones that were not modified.

    See post #112

     

     

  3. Another key factor, which cleans sections of the industry up from time to time, is that when someone has paid, and is badly injured, or killed, he/she or the estate are quick to sue for very large amounts of money. I posted about a manslaughter charge against a woman who reversed the charter boat over a swimmer, and she had all the legal permits - operating illegally, you are in a far worse situation.

     

     

  4. I have constantly pushed the recovery from unusual attitudes aspect (but this is not a factor for pendulous craft).

    In the material I put up there were at least two stalls shown on pendulous aircraft, where the pilot had got himself into a position where the result was an inevitable drop to the ground. The is another post somewhere of a pendulous aircraft developing a rocking pitch which progresses to a continuous head over heels tumble to a fatal conclusion. These things have a lot more moments than, say, a Gazelle, fortunately mostly near the ground, (where there's no chance of a recovery).

     

     

  5. Turbo, with 13 of your examples being PPGs which you know are different I can only assume you are deliberately trying to mislead. If the media had printed that you would have been all over them.

    You can rationalise it however you like. PPG dymanics are similar enough to show that

     

    This file which I put up a few posts ago has around 50 incidents listed including at least one fatal: www.part103.org/PPC/parakeys/ppc_adb.doc

     

    If you want to promote a reduction in training standards, it would be better to do the research first, rather than get caught out by these embarrassing facts.

     

    As a matter of interest, currently in Victoria it is mandatory for a learner drive to accumulate 120 hours before becoming eligible for a probationary licence.

     

    PPC has its place in aviation, but don't over-sell it and screw things for the rest of us.

  6. inherent stability, can't stall or spin.

    This is what you were telling people David, and it's simply not true.

     

    It's all very well to dismiss each accident as you did - we all know exactly what went wrong when we see the videos and get the reports, but I'd suggest that none of these people thought they were going to come unstuck.

     

    It seems to me that the RAA approach may be in the better interest of the wider recreational aviation industry after all.

     

     

  7. Luckily there doesn't seem to be a lot of people reading this forum otherwise I might bore them to death repeating my main issue, which is the powered parachute is a completely unique flying machine, very different from fixed wing aircraft in their design, risk of flight, ease of flight, inherent stability, can't stall or spin. Because of those differences they and their training requirements should be different from your style of aircraft.

    Inherent stability? Can't stall?

     

    I have no problem with any parachute related activity. If you have been thoroughly trained, and are able to maintain skills to the same level as other forms of aviation, it can be a safe activity.

     

    If you don't think a chute can stall, have a look at some of these videos.

     

    PPC crash – Gulf of Mexico: Pilot dies

     

     

     

     

  8. Probably true Turbs. Random factors abound, but we can thank the Americans in particular for exhaustive testing so they could predict the service life of many components.A Boeing engineer investigating a 747 crash found a new bulkhead had been installed with a single row of rivets rather than the recommended double row. Testing data predicted a single row would fail after 10,000 hours in service. This particular one lasted over 12,000 before causing a catastrophic crash.

    That is how we like products to be designed, and certainly to be thrown out on the tip before any safety related component fails.

     

    In many cases components will fail in a cluster - all around the same time. If that isn't satisfactory, we can redesign the component to push the failure point out, or if we know we can't fix it, and the failure is occurring too early we can budget for extra expenditure and fix the failure under warranty with minimum distress to the client.

     

    However, occasionally we get a random failure, and that's a nightmare.

     

     

  9. In the big picture, of total engine sales, if there is a problem on some engines, and not on others, or if it occurs at different points of the engine's life cycle it is a random issue.

     

    Where both factors are in play no one knows exactly IF it will happen, and no one knows when it will happen.

     

    So an individual's experience isn't worth a crumpet, and is not the basis for telling someone else he will be safe.

  10. Quite true FT. By that stage, given their pig-headed nationalism, the end result was inevitable. Had the west allowed Japan into their "club" things may have been different. Moderate politicians might have steered Japan away from war. Instead, they were humiliated by the west and militarists murdered their way into power, then set their country on a course for disaster.Given this historic lesson, G W Bush should have avoided uncorking the powder keg that is Mid East ethnic politics.

    Can't you even read to the end of the sentence OK before getting on your hobby horse. What the Japanese did in China in 1937 was inhuman.

  11. .............it will never go anywhere because everyone on this forum will tell you that journalists never write the truth, especially the Murder Press, who every day start a war, and pinch women's undies off clothes lines, and.......

     

     

  12. Hi TurbsConfess I was wondering how it was that the only part of the Moorabbin paddock available had another a/c taxiing on it. The two involved could taxi side by side on those big runways and there are a lot of choices there. Kaz

    There's two active runways, but yes plenty of space steer around; at least with this one we are likely to get a very detailed ATSB report to use on us mere mortals.
