    I didn't bother with 1 nm measurements. To fly better than about plus/minus 3 degrees over 60 nm is doing pretty good. Also, without decent ground features to identify the 1 in 60 technique is hard to apply. Here's a track I flew on a wet and windy day. Dodging rain showers made things interesting. The GPS was just logging my track, no display available. Maybe there is no link to the graph, the dude who posted it may have created it himself. I'd like to know what he used as Excel is crap. I use Python for stuff like that.

    Good Heavens - I learnt the 1 in 60 rule 35 years ago, I didn't think anybody bothered these days, especially with the electronic gizmos. The 1 in 60 rule is used to estimate angles to determine track and heading changes. If you're off track by (say) 30 degrees and have been for (say) 10 minutes you would use diversion procedures to get back on track. Pages 14-19 to 14-27 in book 2 - Meteorology & Navigation by Trevor Thom. The 1 in 60 rule is much easier to apply when you have your track marked on a map with lines every 15nm or so. I only ever used it on big navs that required the WAC and covered hundreds of nm. I am glad I stayed awake during geometry/trigonometry class because that's what the 1 in 60 is all about. I love this stuff, it keeps my remaining neuron active...

    wow - that's a fine looking digital temperature meter. ? Don't slice yourself open on the sharp fins....?

    I cannot seem to understand what this post is saying. I hate being old.

    I'm no expert but aluminium and copper are 'dissimilar metals' and don't like contact with each other, leads to corrosion. I discovered this when building antennas as a kid. So, I wonder how they did it.

    Seems two have died in a plane crash, Qld I think, news so far is sketchy
  8. Jabiru7252
    Stall times 1.3 would be my recommendation. One tight turn with such a small margin may see you come unstuck fast. Also, best glide speed doesn't always matter when you are weaving about to get a good approach into a paddock without an engine running.

    A witness clearly described the wing 'folding up'.

    News just coming in about a plane crash and two deceased in the Hunter Valley, NSW.

    After reading my post (Nov 17th) it looks like I'm suggesting this bloke did do a beat up. So, I'd like to say that I'm not suggesting anything. I wasn't there, didn't see a thing. I would like to add that I was once low over a fence because of a short strip, the wind stopped and I sunk like a rock. Had the tires been new, I would have hit that fence. Then many would have said I was flying too low.

    Oh well, we'll get up in the morning and go about our lives as normal but this dude will probably never fly again, maybe never do anything again without a limp, a bib or a napkin and all because of one dumb mistake. Think hard folks, DON'T decide a low, fast beat-up over the homestead is okay. DON"T think a wing-over is cool to impress your friends. You have already impressed them by having a pilot licence. Bogan attitudes won't do any of us in recreational aviation any good. Stay safe...

    As long as we keep our complaints on forums nothing will change. When we start dragging the greedy rich into the streets and beating them on the kidneys with big tree branches until they pee blood, things might change. But, having said that, I'm a greedy rich person to some while a lowly peasant to others. It's all too complicated. I'll have another drink instead.

    Sad sad time...

    I think the original problem was: Can we have a solution such that during flight, and with some accuracy determine how much fuel is remaining in the tank of a Jabiru SK. The level is hard to see when it's low and swiveling around to view it isn't that easy. The Jabiru SK tank is not long and flat, it's a box shape. I think my idea would work. I also built a prototype level indicator on the bench using ultrasonic sensors and an Arduino micro purchased from Jaycar. That worked quite well, just more work getting it setup properly.
  16. Jabiru7252
    Here's an idea. Have a tube with a sliding rod in it fixed to the top of the tank so that a float attached to the rod is just above the bottom of the tank. When the fuel gets low the float (and hence the rod) slide down allowing a micro switch connected to the top of the rod to activate a light on the dash. No electrics required in the tank and if the plane lands upside down, the fuel can't drain out of the tube because the end will then be above the fuel level. The rod assembly would not need be any wider than a pencil. Then again, it might be a nuisance having this assembly poking up out the top of the tank...

    Then I must ask, who in the Union has the right or expertise to comment? Surely they would consult the engineers? Maybe I'm expecting too much?
  18. Jabiru7252
    If the engineers are saying the aircraft should be grounded, who in Qantas has the right or expertise to say that is nonsense?

    Today's UAVs (Unmanned Aerial Vehicles) are the UFOs of the 60s and 70s. Military research and development. People reporting UFO activity these days is almost non-existent because most know that those 'lights zipping about in the sky' are almost certainly some kid flying his $49.99 quad copter.

    The lack of circuit diagrams and board layout doesn't help a tech either. I wonder if there is a 'reset' button hidden away or a 'special' turn on sequence that might set the thing going again.

    Considering the stupid things pilots are doing lately, perhaps IQ tests should be introduced...

    I would think that in the 21st century there would be no need to have a paper based magazine. However, some think I'm stupid.
  23. Jabiru7252
    Some books I have read and recommend.... Shadow of a Tiger by Lionel Parker. Boy Phoenix by Helen Blake. The Sky is Not the Limit by Matt Hall. QF32 by Richard de Crespigny. Amelia Earhart by Elgen Long and Marie Long. I found them all a good read.

    Yes, the audio says first lesson but the text overlay said third. Typical crap reporting I guess. I wonder if he had spent a lot of time playing flight simulator on the PC.
  25. Jabiru7252
    His first lesson? I understand it was his third. Regardless, he did a good job. Let's hope the instructor is okay.
