    I just want to know why the answer at perris wasn't "just no"



    I take this back after seeing the video of his chop. I might have too and definitely would have if it was an AFF jump.

    Yes, he IS a tool but maybe he can get many more people interested in our sport too?

  4. This is addressed to all DZO’s. It’s in response to a recent video of a student cutting away far too low, that made the internet and was removed a few hours later. This video is excellent training material that should be shown in every FJC from this day forward. Someone did everything wrong and got incredibly lucky. Students need to know the trouble they can get into.

    Luckily for us, this is the internet and it still exists: https://www.liveleak.com/view?i=607_1516923160

    Stop hiding gnarly video. Shit happened, was captured on video, no one died, and now its training material. This is a dangerous sport. Shit is going to happen, and when it does the community needs to learn from it.

    No tandem or AFF student is going to go to the other DZ because some video of a tail wrap on your aircraft exists. They wont find it and if they do, they don’t know what that means, or the risk to the passengers and aircraft. Theres a video of a porter stall spining for many thousand feet on the internet. Call that DZO and ask how much his tandem business suffered when it came out, I’ll bet he didn’t notice.

    Sure, if you have video of a student almost fall out of the tandem harness and live or a tandem elevator ride, maybe delete that one.

    But when we have a sport fuckup on video, that should be public knowledge.

    These singles carry almost as many jumpers (18) as a Twin Otter (up to 24) but cost perhaps half as much to operate and can be turned with fewer jumpers.



    I can't imagine the second spinny thing actually makes the cost of operation double.

    According to an article the blackhawk caravan burns up to 65gph while a twin otter burns 90gph. Assuming you can do four full loads per hour in the blackhawk and three in the otter that makes 72 jumpers per hour for each craft.

    Assuming you pay $20/load and fuel costs $3/gal the blackhawk will cost $275/hr while the otter will cost $330/hr.

    So yeah, a B model blackhawk is more efficient than an otter but not by double, more like 20%.

    Flat glide angle implies a shallow angle of attack (flat) producing slow forward speed (less drag) and slow rate of descent.



    Slower airspeed actually means less parasite drag and more induced drag (drag resulting from lift). The attached graph illustrates this principle.

  13. In a word: fast. Things seem to happen very quickly at this loading.

    I stand almost all of them up, I've heel slid to my ass or tripped trying to run out a fast landing.

    I'm flying this loading because its what the used gear that fit me at my dz was built for. I'm aware of the danger but its always the other guy that actually gets hurt, right?
