    Did you notice the negative dihedrial at the start caused by the positive flap? Also the wing flutter? Apparently that was caused by Terry cycling the flaps from full positive to full negative a number of times. I think that the Boeing 787 has ASH 25 like wings - for a jet airliner. High aspect flexible wings may be the future for power aviation.

    One way to get glider aspect ratio without the span. Of course, it suggests ideas for gliders as well - like a 27M span box wing. :) The article includes a link to the NASA/CAFE competition.

    Landing is not optional but taking off is. :)

    Wave flying at Minden sets record.

    Interesting. Thanks for the info.

    Interesting. It is a bit of a worry to know that it is possible to rip the rudder off in flight. My guess as to why the B52 was at low level is because flying at 500' AGL is one of their tactics.

    When the engines fail the best option is to land and the safest place to land is on a runway designed for the purpose. There are no better options. Why do you think he would he not make the runway? As I understand the incident the crew did not start selecting landing options until after the engines failed. The time to make that decision is before the engine failure.

    Which is why an immediate turn back was the correct decision in this case. In the event of engine failure step one is to establish a safe landing and once that is done step two is to fiddle with the engines to see if they can be restarted - not the other way around.

    I've not flown a large plane but, AFAIK, side slipping a large plane is no different from doing it on a small plane. Maybe somebody with experience can comment on size and side slipping.

    Well, unfortunately, you're not going to get a towing endorsement to tow gliders without a PPL (it does not matter if the tow plane is RA-Aus or GA registered). With respect to towing hang gliders I do hot know how that works endorsement wise. No, my name is not Hugh.

    I don't understand. Most gliding clubs are happy to have more tug pilots. If you have a tail wheel endorsment they will probably check you out on one of their Pawnees and then you can use that to get you towing endorsement. At one stange Beverly was short of tug pilots. I'm not sure what their status is now.

    An article about this incident and ground collisions in general.

    More information in the on going Blanik saga. Scroll down to the bottom of the page and read the FAQ to discover the cost and how many original hours are re-installed - 3750h. So, if your Blanik already has more than the original design hours, you are up sh.... well I think you know where you are.

    A coverage map is avaliable on page 1 of this document. But, in addition to ground coverage, most airlines have Mode S which supports aircraft to aircraft communication.

    Two Planes Collide at JFK.

    If the slant range is 500 meters and the vertical separation is 300 meters then the observed angle from the horizontal is: Theta = +-ARCSIN(300 / 500) = +-37 degrees That would not be consistant with "at out height". If fact it is unlikely that a plane at nearly 40 degree from the horizontal could be seen from a cabin window.

    But they were both traveling the same way and were aware of each other. This situation should have been avoided by use of ADS-B but clearly was not.

    Talking about rope breaks raises another question. When I'm on tow I often look up at the weak link and shackles at the other end and ask myself, "Do I want all that stuff in the cockpit with me?" The answer is no so I sit slightly to the left of center - which also helps with the torque reaction on the tug. Does anybody else do this or is it only me?

    This year's Grand Prix is being held in Romania.
  21. Exadios
    500 meters is too close and if they where flying in the opposite heading they should not have been on the same flight level.
  22. Exadios
    Rope breaks on aerotow are rare but they do happen. This one in the US resulted in a death.
  23. Exadios
    Sure. But as a solo pilot you would hardly ever fly the DG by yourself. A single costs about $36 per hour. Also you would never take a tow to 3000' or 4000' AGL. It is more common to get off between 1500' to 2000' AGL which equates to $27 and $33 for the tow. In addition a normal glider flight is 2 hours or more which halves the hourly rate of the tow. Of course not every tow results in the glider getting away and this tends to raise the cost of gliding. (This has never happened to me but I have heard of it happening to others. ) Costs aside gliding does teach skills that make a power pilot a better pilot, IMO. So, for the power pilot, learning to glide is money well spent.

    Seven flights to go solo is not bad. You must have impressed the instructors. I think you've misrepresented the costs a little bit. A DG1000 is usually an expensive air craft to hire. More representative is a single which would be about $35 / hour for the glider and about $30 for the tow which equals $75.

    I have a report about an RAA crash this weekend at Boonah. However it is a little vague. Anybody know whether there was another incident at Boonah this weekend?
