    Fire work takes a special skillset. Low level work (treetops), precision drops, localised crazy wind shifts.... must be exhausting work. Pic of heli work on a fireground I attended last summer. We were often looking down on the choppers! They could drop accurately within metres of us.

    I was sailing past Margate, watching the flying circus. Very impressive piloting. There were times when four aircraft were skimming the water, loading on the run. Spray everywhere. Not sure but I heard that they drop about 1200kg at a time. The rate of climb was not looking impressive with a load.

    nomadpete commented on red750's aircraft in Gliders

    There is still one of these remaining on the Darling Downs. Built in 1931 (?) And flown by several generations of the same family.

    When I replaced my stator assembly, it was clearly labelled 'Ducati'. No idea which ducati, though.

    The wiring loom was premade. It already has labels on the wires, but since it was premade for a different aircraft, mods must be made to suit a different layout, and some different items. It is messy at the moment, but eventually will be neat and secure.

    Geoff, switchyard back EMF involves spikes several orders of magnitude greater than any tiddly little 12volt solenoids or starter motors. When a switchyard circuit breaker trips there may be 330,000 volts and thousands of amps at play. Nevertheless we should be protecting our fragile and personally expensive electronics on our aircraft. Especially when it is so simple to do.

    Thanks for the post. I have never alluded to being a great aviator, or even being particulaly good. But having watched that Oshkosh video I feel a little better about my flying. These flying applianes do not often arrive back on terra firma as gracefully as we wish them to.

    PS Do they still fit a dkhead diode across the dc supply inside radios? In the old days of CB radio, they were common, and would at least suppress the negative going spikes.
  9. nomadpete
    Very nice CRO pics. Have you looked at the current associated with those spikes? Personally, although I love protection diodes or TVS, I would be tempted to wire a fusible link or fuse in series with it - although failures are rare, the consequence of a short suddenly occurring across your solenoid would be unpleasant. (Such addition would have to be monitored)

    So that's why we can't get good wine here any more. We send it away for all youse foreigners to enjoy.

    I forgive you, Geoff.

    Digressing, but when the first of those CT's exploded in Qld, nobody knew why, but someone reported an increase in RF noise in their AM radio. So, I ended up wandering around HV switchyards nervously aimimg a alloy yagi antenna at CT's, looking for the rising RF that might indicate impending explosion. My apprentice followed me to carry the spectrum analyser. The engineer who thought this was a good idea, stayed in his cosy safe office.

    Here's another one - we also have live line workers in Australia, too.

    Wow! Lucky man! Happy Birthday! Gee, that would look great on the front of an aeroplane.

    My goodness, is that what it does to you? No wonder I look young for my age.

    Trust getting qualifications from online training?

    All the world's a critic. Don't listem to 'im Marty

    You are wasting your time on this. Fitting fat tyres and shiny alloys won't make it go any faster. That only works on old commodores.

    Anyone know if any PC9's ended up in Tassie? Today I saw one over fly Scamander (east coast of Tassie) When I say 'over', I mean maybe 500' over the road and houses, and it was about 90 degrees to horizontal and made a lot of noise. Wasn't very bright coloured, painted drab. If he thought the camo makes him invisible, he forgot the noise got everyone's attention! Do some pilots think that nobody notices this kind of behaviour?

    Wind socks demystified.....
  21. nomadpete
    Yes. Read the POH
  22. nomadpete
    It looks very slippery. Where will the noise come out?
  23. nomadpete
    Rastus, 4000' and going up 🙂

    Watch out.......

    In my past employment we used many magnetic reed switches. The only failures I recall were caused by the rare stuck 'closed' switches. This usually coincided with years of being constantly in the 'closed'state . Never had an intermittent one. If you are worried by the low probability of a stuck switch, add a test into your 100hr/yearly maintenance. Slip the reed switch out of its holder and verify that the alarm works. Better still, you WILL be doing a gravity fuel flow rate check, won't you? When you drain the last of the fuel, the alarm is verified, and the switch gets an annual workout which should prevent long term sticking. Oh, I assume you didn't buy the cheapest little reed switch you could find on the net!
