  1. Have committed much tomfoolery in said type. Really good fun too.Low drag and high inertia aircraft are the ones that usually leave smoking craters

    Fair enough, Ozzie. I should have been more specific about which tomfoolery; the near-ground type especially.

    You probably have a point about the low drag/high inertia ones leaving more holes. At least with a Thruster it's easier to be a few minutes ahead of the aircraft!

     

     

  2. ... it's just momentum vs gravity. Which is why, as you point out, airspeed drops so quickly.

    Plenty of GA pilots converting to little RA types are caught by the shortage of momentum. Thrusters have so much drag and so little inertia they are the worst type in which to commit tomfoolery.

  3. ... hence pull pots etc off and have a look...Russ

    While they're off Russ, might be a good time to install CAMit's forthcoming oil injector kit.

    Ian Bent <[email protected]> emailed a prompt and informative reply to my enquiry. They're sure having a go.

     

    Because my heads are not off, and hopefully won't be for a couple of years, I am looking at installing a simple short-term solution; a nozzle to spray 2-stroke oil down the throat of the carby before shut-down. Neater and probably more effective than the weak oily fuel it currently gets. I just noticed the beginnings of surface rust on the outside of my barrels, so I'd better hurry up.

     

     

  4. ... these three aspects need to be removed from CASA and put under a separate body whose function is clearly recognised and set out in its charter, to be to make whatever adjustments are needed from time to time to keep the aviation industry running safely and efficiently. Then CASA's job is simply to see to it that the industry follows those rules.

    All excellent stuff Dafydd, but can you imagine this government being seen to add yet another authority to the bureaucracy?

     

     

  5. ... we have become a nation of overweight and obese people to a level never seen in the past. Have a look at some old newsreels only 20 to 30 years ago & there were only a few overweight/obese people around. ...

    So true, KG. Angelina Jolie just finished filming scenes for her new historic movie just up the road from us. Lots of locals auditioned as extras, but few made the cut. They were looking for thin and skinny. Damn, I should have tried out...

     

     

  6. Welcome aboard Brownshoes. You will find this site very stimulating; a big range of opinions, experience and locations. As I told the founder, Ian Baker: this site is the Wikipedia of the Air. Almost any question will be answered.

     

     

  7. Poor bugger! Do airline booking systems have secret access to our vital statistics? I am skinny and have twice been booked next to huge blokes. Luckily they were clean and polite.

     

    Samoan Air are the first to have the guts to charge fares according to weight. More should, as most overweight people have some choice in their body shape.

     

    I don't. Nobody caters for my height. I am accustomed to having no leg room and enduring seats which aggravate my back problems. End of winge.

     

     

  8. Nice read. That Meredith Effect is a smart idea. Wonder why we dont see that used more often. Seems like a good solution to the ever present problem of cooling v drag.

    Good point, Doc. The extra efficiency would sure cut down on fuel use. Perhaps the reason is that wartime aircraft with large engines had a lot of waste heat available to assist thrust. Modern piston-driven aircraft, with smaller engines, may not produce enough waste heat to warrant the design effort required.

     

    I invested a lot of effort in adding exhaust augmentors (an energy-saving idea from the same era) to my little aircraft.

     

    The waste heat from my tiny engine only gave about 3% more power, but I was nearly deafened.

  9. Hello everybody, not much flying going on in the UK at the moment for us Microlight pilots. Fortunately I am due to be heading to Perth (West Australia) later this year with work so if anyone has any experience of getting their UK NPPL(M) endorsed for use in Australia, I'd be grateful for any advice.

    Beewdmalt? Bewdmait? Bewdie mate? Not much of a code-breaker; help me out?

     

     

  10. The fix has certainly made a bit of difference to starting some Jabiru's. Personally I like a primer to all the cylinders. An uncertain starting engine is no fun. You never know when you are going to get stuck somewhere. Nev

    Drilling out my "choke" jet sure made cold starts easier, but having the minimum sized battery (120CCA, weighing 3kg) means you don't waste cranking power. (In fear of being stranded, I have taken the damned battery to bed with me to keep it warm!) I fitted the cold start kit, had a problem, they replaced it with a better design and that seems to be working. Starting with one or the other coil earthed seems to make no difference, so I wonder if it's working. Winter will tell.

     

     

  11. The whole truck industry now operates under Chain of Responsibility legislation where, if the distribution manager of a large company coerces a trucking company which coerces a driver to drive out of hours, all the people up the line can be charged for any resulting accident, and already there are cases where they have been.

    Having lost a truck-driving family member to fatigue and attended numerous truck crashes, this topic has my attention. In recent years there have been very few accidents in our patch, despite ever-increasing truck traffic. The reforms have saved a lot of lives. We now have national transport firms whose proudest claims are about the safety of their drivers. Keep up the good work Turbs.

  12. Many of the often removed access panels on military aircraft use captive nuts/nutplates, usually the only reason we have to change one, is that some numpty pushed really hard while undoing it and forced the nut section out of the riveted plate. They do last a long time, and with regular use, even if they start lose run on torque, often you can just use a new screw and it will be fine.

    As a precaution, I grease the bolt threads. I hope this prolongs thread life.

     

     

  13. Doc I agree with most of what you say, but Nev also has a point. Much Australian business management has been woeful; but they have become adept at making excuses for poor decisions and lack of vision.

     

    It took our car industry 40-odd years to decide to produce 4 wheel drives, too little too late. We export some of our best and brightest people, frustrated at the lack of opportunities in their own country. Australian architects are driving some of the most innovative new cities, while people at home mortgage their life to buy unimaginative, inefficient houses.

     

    We can do far better. One ray of hope is that most expatriates return, bringing new skills and experience. That gave NZ a viable film industry and is doing the same for Indonesia. I'd like to see my countrymen sent on a fact-finding mission around the world.

     

    Perhaps this deserves its own thread:

     

    I'll kick it off with Japan, where we could learn how to build, run (and value) a rail system.

     

    Any other contributions?

  14. Educational thread. I have a trio of captive nuts doing critical jobs. Instead of nylon inserts, they seem to rely on having been squeezed slightly flat. I was advised by the seller that they could cope with being removed and reinstalled hundreds of times without losing their grip. Sounds too good to be true. Any comments?
