    Next time I take off I'll look under the plane and see what is pushing me up:loopy:

    I did glider towing for the commercial side of a gliding club on a PPL. Didn't get paid in cash but compensated other ways. Call CASA and remember the name of the person you talked. If you don't like what he said, contact someone else untill they sing the right song. Did that many times in other circumstances.

    I don't believe that downward deflection provides all the lift and don't believe the theory taught in flying schools has been all wrong. To prove it mathematically would take too much time for me. As long as I get sucked up into the air when I pull the stick back, I am happy [my scienfific explanation]

    Out of all the thousands of bolts made, some must be duds. Do they get checked with x-ray or something. When your life depends on one bolt holding, you get critical. Never used to worry until I started snooping around to see how a/c were made. I would design two bolts for every critical fastening.

    My last two a/c have had the wings held onto the fuslage by two bolts each. Not much room for redundency- if one breaks there isnt another to take the load like in an airliner.

    That makes sense and so it is most likely to be true. And I was looking forward to moving into a new house:yes:

    Compression won't tell you how stiff the engine is. The hottest parts are proboably giving the most stiffness including the aluminium piston which is expanding the most. Don't worry your little head, all the parts are manufactured so they have the correct dimentions when the engine is at normal operating temp and the engine will be more stiff. Of course if the engine is way too stiff then there may be a problem. An experienced hand will judge that.

    Lots of conflicting info from different sources [would your really bet your house]

    All the moving parts in your engine expand when heated so it runs tighter. If the engine runs too hot, the engine seizes up because it is too tight.

    Lay $100 notes flat on your wing and they will have an aerodynamic curve before they all disappear into a slot near the fuselage marked "a/c ripoffs"
  12. Sapphire
    Yours is just like every other engine. If by some weird circumstance you have max compression cold, you have problems.

    Looks like my first solo nav in a Warrier to Brisbane airport. Arrived and saw hardly any a/c. Stopped for a few minutes then got clearance to taxy. All of a sudden I was surrounded by airline traffic infront, behind, and beside me. They must have closed down the rest of the airport when they saw me arrive.

    Nev said: The position of the ring slots will cause that Actually I read a comprehensive, scientific article on that whether the position of the ring slot position makes a difference. It was concluded that it didn't. However every car manual has you put the ring slots in a particular place. If they rotate, why bother in the first place. One of the smol [sweet mysteries of life]

    Just widen the road, block off each end, and use it as a cross strip. Instead of cars and planes potentially colliding, only planes now will potentially collide.

    Of course, ever notice that a $100 bill always lies with an aerodynamic curve to it-you are getting funnyer all the time nev.
  17. Sapphire
    Yeah, basically you are betting your life that the engine won't fail. A twin would be good. This is even better

    But can you hold your breath that long motzart-it would take longer than one of your symphonies:smash pc:

    Another problem is as a power pilot you don't get much practice doing gliding, so getting it right is more uncertain. I admire airline pilots who have had all engines fail and land on some distant remote airfield that you can't even see initially. Having a co-pilot makes a big difference, one flying the a/c and one doing all the calculations.

    Put the $375000 in the bank and use the earned interest to hire. Better than buying it, getting tired of it, then selling it for $50,000

    Thats a good point too, Turbo. He is climbing out and the engine fails at 600 feet. A lot of decisions and things to do. Now he has to stabilize the speed, do a 180 degree turn, decide if he can make it back [what is the glide angle, what is the glide performance of my a/c, will I have massive sinking air or lift getting back, will I have a tail wind or head wind, where do I go if I can't make it? Or he can pull a lever and parachute down with no more decisions to make.
  23. Sapphire
    Of couse we wern't there in the plane to analyse the situation when it hapened It's the glide angle distance that you have to judge by eye in seconds and determine if you can make it. 600 feet altitude means less than you think. Glider pilots judge glide angle distance every minute they are up. I am inclined to think that he decided to use that device in any suitable emergency, when he bought it. That, along with fully insuring the plane would in his mind give a winning outcome.
  24. Sapphire
    I bet he wasn't a glider pilot.
