    Calling any Speed Skydivers

    No, you need 2. A pro track and another audible, both in your helmet. For competition, the organisers supply two pro-tracks for your harness. For qualification jumps, they use the 1 pro-track in your helmet, so you can use that for training as well, unless you're rich. Not all Jump-Track software, L&B discontinued it in later versions.

    This ^. You can't look at a wrist alti during a speed jump without either going unstable or losing a hell of a lot of speed. You absolutely need an audible, you need two audibles. I use an Optima and a Pro Dytter (which I find the most reliable). For training, one Pro-Track in your helmet would do fine, that's the set up often used for qualification jumps anyway. It won't tell you if your out of bounds of course, but getting the speed wobbles will likely tell you that anyway. The older Jump Track software has speed skydiving functionality built in, the newer versions don't (unless L&B changed it again). I just use the replay function on my Viso to get an idea of how fast I'm going. Speed skydiving is scary shit. Going unstable at 250+mph can pop your shoulders out so keep those arms clamped to your side till you slow down (you'll only make that mistake once), and pulling out of the dive into a track will pull more G's than anything else you can do in free-fall. It still gives me the heebie-jeebies busting 5k at full tilt. Pro-tracks can be a few feet out on altitude so to to get the best average you don't slow down till you're well past the bottom gates at ~5500ft. For training, I still tend to pull out at 5.5k or higher.

    Reserve handle - ring or pillow and why?

    I very often have to climb out and around the door onto the camera step and I didn't fancy snagging a D handle on the airframe dumping my reserve over the tail of the aircraft, so I opted for a pillow.
  4. That's pretty much where I'm at. Not interested in hanging out at the DZ, and sick of losing friends so I've virtually quit. I still have my gear (can't quite bring myself to sell it, yet) and occasionally do a jump or two if the mood hits me, but I've got more interesting things to do these days.
  5. Of the places I've jumped, most pilots will put the flaps down but a few like to run in a little faster. But then I've also been in a Twin Beech trying to stay with a slow flying Caravan on jump run when the Beech stalled with half a dozen 200# gorillas hanging on the outside of it. Of the two scenarios, I'd rather take the fast run in.

    Skyhook Video

    Since there are no photos of it disconnecting during deployment, you have no way of knowing that. Guess all you like, means nothing.

    Nah, that was a skyhook deployment. 3 consecutive frames pic 1: RSL shackle pic 2: RSL being pulled pic 3: skyhook pulling reserve bridle Blink and you miss it.
  8. Then whoever was spotting needs to get their shit sorted. You aren't spotting for yourself, you're spotting for the entire load. Then you bit off more than you could chew and need to re-evaluate your abilities That would have to be a significant change, but OK. Low turns are probably the largest single factor contributing to fatalities in skydiving today. An occasional out landing is inevitable but if you land out so frequently that you get a history of it, then I reckon that should be an indicator that you're doing something wrong. Apparently you think landing out in random places at regular intervals is fun. Good for you.
  9. One could argue that having a history of making out landings and low turns is a good argument that you shouldn't be jumping until you have a good long think about why you so frequently fuck up your flight plan and/or spot.
  10. Bear in mind that it is quite likely that your harness and reserve also have the same maximum weight limit. But like everyone else has already said, a wing loading of 1.6 at 80 jumps is the bigger safety issue.
  11. That's close enough for most practical purposes but it's not quite right. When you have horizontal velocity into a relative wind, it does affect your vertical acceleration, not by much but it does. If you lobbed a bowling ball out of a balloon and an Otter from 5k, it would hit the dirt first from the balloon, by maybe 0.5s depending on the parameters. The reason is that aerodynamic drag doesn't care whether you are going horizontally or vertically, it only works on the square of the total velocity. Hence drag term in the vertical component of the equations contains a horizontal velocity term and that horizontal speed will slow your vertical acceleration.
  12. Speak for yourself. I went from 270+mph head down straight to belly precisely once. It was like being hit by a freight train. I tend to go into a track from head down, wait for the speed to bleed off before starting to bring my arms out, then get big, wave off and dump.
  13. I'd rather jump with someone who is a bit bored than someone so amped up they don't think straight. Sensory overload is definitely a problem, sensory underload usually isn't. To the OP. In my opinion, skydiving is far too dangerous and expensive to continue if you don't love doing it.
  14. Not really. People use two audibles so that if one fails to work on a jump they still have the other. I want that redundancy because I do certain types of jump (speed) where a visual alti is not really an option so I have to rely on an audible. I really don't want to be screaming through 4k ft at 250+mph waiting for an audible alarm that never comes. I use an Optima and an old Pro Dytter both set to the same altitudes. The Dytter seems to be the more reliable of the two.
  15. It's not a true representation of skydiving at all. Unfortunately it is a true representation of dropzone.com.
