  1. Yeah, Juan was asking the same question, that is, about a kill switch for pilots in case the seat starts moving forward while they're in it (un-commanded by the pilot's own seat switches on the console). The design of the rocker switch on the seat-back presumably assumes that the cover is there to guard against inadvertent operation whenever the seat was occupied. But there ya go In the confusion of having a meal tray plonked down on your moveable table and your sudden realisation that you're being moved forward relentlessly - and possibly being out of reach of the console switches (even assuming they countermand the rear switch) I can imagine the inevitable HF/WTF! pause could easily see you - or your dinner - jamming the yoke forward to no good effect. Certainly would not have been trained for in the simulator.
  2. This recent (30 min) video history of the B727 has a sting in its T-tail for today's Boeing Company.
  3. 2022 Kangawallafox KWF Aircraft | Aircraft Listing | Plane Sales Australia WWW.PLANESALES.COM.AU This aircraft holds the current Australian record for the most touch-and-go circuits in one day. 145 circuits were completed in 6.8 engine hours. I thought that this was the best way for me to prove the concept of the...
  4. Wow! What's going to happen to our friendly, quick and savvy local support service? Will we all be moved over (like it or lump it) to the FF app, after OzRWYs Classic is quietly withdrawn? This comes as a bit of a shock - even for iOS users; a Starbucks style takeover, quite out of the blue. Will AvPlan bat on as the only little Aussie battler EFB?
  5. Not too many takers for Lisa's "Just make the next 5 seconds perfect" little mind trick to counter mental drift (vid above). Well, Paul Bertorelli came up with an equally pithy take on the same subject which might prove more memorable: "You are unlikely to stall if you just take your head out of your ass." He goes on, in this film (posted before) to confess his own failure to comply, which, he reckons, very nearly did him in: https://www.youtube.com/watch?v=-2mzsjXn88Y&t=73s
  6. Yes, I've had quite similar lapses and I know exactly what you mean. But then, it's generally agreed that humans (+ friends) can only really concentrate on one thing at a time; So what to do about it? ... how to get the discipline needed to save us, as pilots, from our primal brains. (To be fair to the Creator Spirit, flying too high with some guy in the sky was Her idea of nothing to do.) Of course, the old "Aviate, Navigate, Communicate" mantra addresses the same (universal) problemo. In any case, I just found this video of a US CFI, "Lisa", in conversation with Rich Stowell. Among other things, she explains that after many years of instructing, she finally came up with her own simple mantra to help her students: "Just make the next 5 seconds perfect". (Long enough for any squirrel to be no-factor ;- ) She explains it from around 06:30
  7. As I read it, anything below 1000kg MTOW will be deemed a tonne of fun, no less.
  8. A rival forty-horse, 4-stroke, one pot screamer is the Airtech AERO1000: AERO 1000 HO ENGINE PACKAGE – Air-Tech Inc. Ultralight Aircraft AIR-TECHINC.COM
  9. As far as I can tell, it's basically a one man operation. One guy with a passion. Here he (in orange) is taking on some of the YT critiques: @andrekemp5059 2 months ago Nice HONDA @kidkhaos6427 2 months ago There are exactly zero parts of this made by Honda. Yes it is loosely based on a Honda. @andrekemp5059 2 months ago @kidkhaos6427 Ok. So is it Chines parts or car parts in there. Because Honda crankshaft and piston rod are great and high quality. Koyo bearings. @kidkhaos6427 2 months ago There are very few chinese parts, but yes a couple. Most are US made from various racing industries or here in my shop. Every part and specification is important and I have not just simply put a prop on a generator engine here. I have gone through several iterations of this to reach successful reliability and power delivery. I have tested multiple combinations of valves, pistons, camshafts, carburetors, exhaust configurations , and so on. The engine you see in this video actually now lives in a box in the attic. It was brutally murdered between the test stand and two different airplanes. I have also revised the reduction drive design since this video was made. This is simply a snapshot along my journey.
  10. I also found that Air Tractor video very helpful; it was clearer than most I've seen on the complex of forces acting on a turning aircraft. I think Nev's problem was with the guy uttering the word "downwind" while talking turns, seeing it, I guess, as adding to the (much discussed) myth of the downwind turn. Like Brendan, though, I doubt that this savvy ag/airshow guy simply buys-into the widely held myth and is, therefore, 'wrong'. The video was, after all, an ad hoc interview and he didn't really seem to finish that thought. If he had, he may have complicated the matter with the 'wind-shear' exception and/or dangerous visual illusions. Who knows? In any case, for anyone interested, here's one example of the topic debated online (with some relevant bits extracted). (There are many discussions of the same thing on here, as well) Why do gusts change the airspeed during landing, but turning (which changes where the wind is coming from) does not? AVIATION.STACKEXCHANGE.COM As we know it, aircraft are extremely sensitive to gust during its final landing stage. They can lose airspeed if the wind changes to tail, ad thus loose lift or need to adjust their thrust in orde... "The myth of the downwind turn ... As you stated the plane is moving along with the airmass. So, for the plane, aerodynamically there is no head-, side-, or downwind. Only us on the ground can feel it, as we are locked into to the coordinate system of the earth with our feet. The airplane is locked into the coordinate system of the airmass, and as long as the airmass itself does not experience acceleration, the airplane flying in it can turn in whichever way, and it will not notice any change in the wind direction. The direction of the wind is locked into the coordinate system of the earth, so in your example there is no change in wind direction." Jpe61 "Windshear (a sudden and/or drastic change of wind velocity) will affect airspeed momentarily until the plane’s momentum is overcome by the aerodynamic forces acting on it. This will be most apparent as turbulence or loss of performance. It is also most apparent during slow flight due to being so close to your performance envelope edge. The sudden gain then loss of altitude when flying through a microburst is a good example of that. ... During landing, your slow airspeed and proximity to the ground combined with the vertical component of your momentum makes any loss of performance dangerous. It could lead to a sudden increase in descent rate at the wrong moment or a stall if you are too slow. A change in wind velocity as little as 5-10 knots can have an effect on the plane. That’s why pilots are encouraged to add half of the gust factor (the difference between the steady wind and the peak wind) to their approach and landing speeds. In your example, it looks like you are concentrating more on changes in relative wind velocity based on changes in aircraft heading instead of windshear. That is different. The aircraft’s airspeed will remain the same. There will be no loss of performance relative to the airmass because the aircraft is flying IN the airmass. The airplane does not care about its performance in relation to the ground unless it is on the ground." DeanF
  11. Here's Kid Khaos demonstrating a prototype and explaining/defending his concept in the YT Comments (Watch on YouTube to see them). And here he is doing some crow hop flight testing. https://www.youtube.com/watch?v=swBVXPkzWUo
  12. Okay ... but to be fair, it is called a Thump-Air (from Chaos Concepts ... powering the Badlands ;- )
  13. Another video about the Badland Ultralight (Part 103 compliant) now sporting the new Thumpair 40 Horse 4-stroke. Badland Aircraft – 100% Part 103 – 100% Airplane WWW.BADLANDAIRCRAFT.COM Thumpair – Badland Aircraft WWW.BADLANDAIRCRAFT.COM
