  1. Detached eddies? That’s all we need out here on the flat country! As others have mentioned, the air can sneak up and smack you. At least during droughts we might get visual warning of a Willy-willy by the dust and crap they carry up.
  2. As you say Glen, it’s not so much their height as the shape of the hills. I’ve met glider pilots who could ride waves up to 19,000’. Those waves were generated by the relatively low Snowy Mts and the ranges east of Warwick. Yesterday I flew for an hour and was surprised by the turbulence generated by the low ridges around our flat Liverpool Plains. Sure diminishes the fun factor. Pre-Covid when flying longer trips I liked to get up above 7,500’ into smooth air. Trouble is, getting down again thru the washing machine is damned uncomfortable, even scary at times. Tha
  3. The KISS principle is important, but simplicity can catch you out. I have a one litre collector tank mounted a poofteenth below the two wing tanks that supply it. Years ago I decided to test the changeover time if one tank was to run dry. I circled our quiet strip until the first sign of fuel starvation (the fuel pressure gauge starts to flicker wildly a few seconds before the engine sound changes). After changing tanks, it took 11 seconds for the engine to recover. I discovered this delay was due to my small collector tank not having a breather line of its own. Aft
  4. The only Warrior I’ve been in impressed me. A Kiwi farmer took me into some short, rough paddocks without a worry.
  5. Good point, Flighty. I almost never do, but sometimes we need some practice in case things go quiet. On Wednesday I did a few approaches on full flap and managed some nice short landings. While focussed on nailing the aiming point, the ASI slipped way back to Vs1.2. Luckily there was no winds shear or turbulence.
  6. Alan I’ve done a lot of mucking about with fuel vent locations and have learned that the tank must have positive pressure. Rearward-facing vents may result in air being sucked out, leading to fuel starvation. Besides the direction it faces, the location of the vent is also important. I once took off without properly securing the cap on one wing tank. The low pressure around the cap sucked out some fuel and when I switched to that tank the engine spluttered. Even my wingtip vents have been affected by vortex currents; I had to find the best spot and align the vent into the airflow.
  7. The Provost looks almost identical to Australia’s Winjeel, but I can find nothing written about this. Even more interesting, the Provost’s designer, Henry Milicent, migrated to Oz after working on the Provost, but his Wikipedia profile contains no mention of him being involved in the design of the Winjeel.
  8. This discussion belongs on the Off Topic site.
  9. APenName… is right about recent aggression by China, which is perhaps understandable given the couple of centuries of humiliation they are emerging from. I believe China claims they are just reclaiming territory taken from them in the past by aggressive colonizing European powers.
  10. Mostly because Australia lacks the forward-thinking of the Nordic nations. Norway owns it’s mineral wealth and now has over a trillion dollars in national savings. Australia has a national debt of around a trillion dollars, despite having massive mineral wealth. The difference: Whitlam’s government was crucified for trying to get control of our mineral wealth, while Norway’s government managed it.
  11. Thanks for injecting some realism into the discussion, KG. We have been raised in an ocean of US propaganda about the “Soviet threat” with outrage that a few “Russian Trawlers” might be eavesdropping on western military exercises, while our side conducts massive surveillance on them.
  12. Yep. All the Way with LBJ is the basis of our defense strategy. Spacey China hasn’t invaded distant lands like other great powers have done, but plenty of countries on their borders have been subjugated and flooded with Han Chinese immigrants: Tibet, Mongolia, Sinkiang… Despite the claims by the CCP that they respect and protect minorities, there are some disturbing stories leaking out that don’t. Their neighbour are pretty nervous about massive miliarisation of the South China Sea. China can claim some historic connection with these territories, but tha
  13. I’ve been searching for some evidence that John Thorpe was influenced by the Jodel wing. Couldn’t find any, but discovered that he designed the Fletcher as a light attack aircraft. Another of those designs that adapted well to another function. I love the bent wings for a number of reasons, one of which is that you can side slip until almost on the plurry deck!
