  1. I used ANR in an SPH helmet for a couple of years but found there was considerable and uncomfortable distortion when flying with doors off or windows open. Now I use CEP and custom moulded earplugs and am quite comfortable. I might have tinnitus if I knew what it was, and if I did it would "sound" just like a C20 compressor whine.

     

    Season's best to all!


  2. Thanks all for the discussion, very informative!

     

    Fire Eyes: I've tried using a variety of USB 2.0 hubs and that didn't work. I tried it from the Windows (Parallels) virtual machine on my Mac and that didn't work. A friend of mine suggested using a wireless USB 2 hub but I can't find one that's run on my Mac or Windows Parallels. I've tried every setting, port, software etc that I can think of. Frick!!! I too am searching for a solution...


  3. Recently bought a new Macbook Air, love it! Fast, light, Parallels runs Windows (Flightduty.xls) no problems. Great computer...

     

    BUT it won't recognize my Garmin 296 gps. Both Garmin and Apple acknowledge the problem and have no plans to fix it. Apparently, while the USB 3.0 ports on the Mac are "backwards compatible", they're not compatible with a relic like the 296. Shyte! Anyone have a proven fix for this problem?

     

    So I'm likely to be forced into the current decade and join the iPad cockpit crowd. Foreflight and Air Nav Pro both look pretty good, each with it's strengths and weaknesses. I really like flying with the topo maps on my 296, are there any iPad aviation solutions that include the option to display topos?

     

    Thanks!


  4. Thanks Skullcap,

     

    I'd suspected the landing gear had to be bonded to airframe, but never seen the piece 'o wire.

     

    I think we're saying the same thing about the hose nozzle. My point about the A* spout is primarily in comparison w/ 206 where the hose nozzle usually bonds to the airframe through the range extender. On an A* if you're not using bonded hose the nozzle has to be in contact with the airframe in those first few inches of the spout, otherwise the nozzle can build a static charge which could lead to arcing and other unpleasant consequences.

     

    Your examples of the pump internal shorts should be enough to convince everyone of the wisdom of using a bonding wire.

     

    Cheers,

  5. If the drum and the a/c are sitting side by side on the same piece of earth are they not both grounded?

     

    But what about the rubber fittings between the landing gear and the clamps, don't those insulate the rest of the a/c from the ground? Darn!

     

    How about if I use a piece of cable to connect the drum, which is sitting on the ground with the standpipe screwed in and the pump clamped on (therefore all bonded) to the grounding point on the a/c? Just gotta be sure to use the teeth on the clamp at the end of the cable to scratch some of the paint off the barrel so that the clamp makes good contact with said barrel. Still not as good as a grounding post, but good enough?

     

    And one mustn't forget when refueling an A* that only the first few cm of the fuel spout is grounded, cuz the further down the spout is either the plastic tank or the rubber piece connecting the tank to the mouth of the spout. Good time to have a bonded hose so that the end of the hose isn't sitting in the spout generating a nice little static charge!

  6. Personally, I'm against airing dirty laundry in public. And there's always some dirty laundry because none of us are perfect. There are plenty of appropriate channels and this ain't one of them. It may not be so for everyone, but for me this is more about respect than fear.

     

    That said, I'm trying hard to understand the fearful part, and suppose that to "air" is human, and 'tis better to air than to allow fouled laundry to moulder far from the light of day.

     

    Sheesh, I need another cuppa coffee!
