    Why would a "real camera jump" be more dangerous than a casual "let me just turn on the gopro and forget about it" jump? "Real camera jumps" require real planning and really thinking about what you want to do and what could go wrong. Focussing on this task and planning for all possible situations does not seem so bad to me. Lots of people have experienced the fact that the "flightrecorder/blackbox" approach has not worked for them. Lots of them (me included!) found themselves in a situation where they made dangerous choices during a jump that they wouldn't have made if it wasn't for the camera. By the way this never happened to me during any "real" camera jump, only during casual jumps.

    I'm wondering if the pressure changes very much when you open the door, to be honest, I don't think I can even see this on my altimeter. Second problem is the time it takes for a GoPro to make a Wifi connection and turn on, this can easily take half a minute, maybe enough to miss the exits. Unless you keep it switched on, but that drains the battery.

    Seems like we had the same problem :-) At our dropzone we mounted a GoPro on the strut of our C182, mostly for the purpose of debriefing static line exits. The standard remote sucks, pilots often have trouble controlling it because they are too busy flying the airplane (lazy bastards). So this winter I made a remote with big switches, and so far, it has worked nicely. The pilots seem to like it too. [inline DSC00260.JPG]

    *** I mean you're lumping low turns and swooping into the same category of risk as wearing a GoPro... one is the number one killer of skydivers, the other just isn't... How can you be so sure that it isn't? An awful lot of close-calls are related to cameras. Some are related to snags. Many (most?) are simply caused by the distraction of getting the shot or getting it to record in the first place. We only know this because the persons survived, and were able to share their experience. If they hadn't, it would have been impossible to link the fatality to the camera. So how can you be so sure that the fatalities that did occur, are not - at least partially - caused by the distraction of the camera?

    Also, have a look at this list of incedents: http://www.dropzone.com/cgi-bin/forum/gforum.cgi?post=3894693;sb=post_latest_reply;so=ASC;forum_view=forum_view_collapsed;;page=unread#unread

    It is not uncommon for new jumpers to get more scared once they get a better understanding of what they are doing. However if you manage to get over this fear and continue jumping, and continue to build your skills, you will gain more confidence in your own ability and the fear reduces again.

    Surprising result! I wonder if it has anything to do with behaviour, where drivers of big cars feel safer and therefore take more risk (a bit like we see in skydiving sometimes).

    is that the Mexican Congress he will be asking? :-)

    Amazing.... how the hell can this be seen as a problem??? My old car easily manages 40 mpg....

    I don't think I've ever met a Dutch person who couldn't speak English! Google tells me 90% of Dutch people speak English as a second language Edit: Oops sorry eVH, I appear to have edited your post rather than post my own! They suggested contacting the KNVvL as they are very helpful and suggested the exam could be translated.

    The good news is that it probably will not matter much in practice for everyday jumping, because instructors will most likely require you to abide the Dutch regulations, and they don't even know the British ones. But for getting ratings, it gets complicated. I don't know if BPA lets non-BPA instructors sign off tasks. Also the requirements for getting some ratings may be different. I don't know the BPA requirement for getting your tandem rating, but I think USPA requires 500 jumps, where we (KNVvL) require 1000 jumps (+D licence, etc.). This makes transferring a foreign licence difficult sometimes.

    1370? Don't you mean 1630?
  13. evh
    Yes you are right. I couldn't resist checking the manuals :-) For Cypres: "It will activate the release unit when it detects a rate of descent higher than approx. 102 mph (approx. 46 m/s) at an altitude below approx. 750 feet (approx. 225 meters) above ground level (AGL). Unlike the Expert CYPRES, the Speed CYPRES ceases operation below approx. 330 feet (approx. 100 meters) AGL." "The Argus releases at 820 Ft. (250 meters) and below if a speed is reached equal or higher than 78 mph (35 m/sec). The Argus stops monitoring and goes to stand-by after it detects an opened parachute." 102 mph is fast, but so is the newest generation of ultra fast swoopmachines. I can imagine that between 750 and 330 feet, they reach vertical speeds that are close to the firing parameters of the speed cypres... Is that correct? Or are they still a lot slower than that?

    The Cypres cuts the loop when it fires? hahaha
  15. evh
    What answer did Argus have for this situation? What is the difference between a multimode Cypress, where the user accidentily selects the wrong mode, with an Argus where you can make the same mistake?
  16. evh
    Yes agreed, thanks for the emphasis. What I am trying to say is that you should not rely on an RSL/Skyhook (or AAD) at all, ever, when deciding on your harddeck. Because they may, and sometimes do, fail.
  17. evh
    Based on his description I'm pretty sure this is not the case. He said the opening was not faster than his previous reserves on his own rig, which has an RSL but no skyhook. He probably pulled the ripcord when the reserve was already out of the container. But I was not there, and he had the reserve repacked before I could have a look. But even so; RSL shackles do get disconnected sometimes, making a cut-away at 100 ft a pretty dumb decision.
  18. evh
    This may be true. A friend of mine once borrowed my rig, had a spinning mal and cut away. He claims the skyhook did not work, and the reserve opened when he pulled the reserve ripcord. I wasn't there so I'll take his word for it (also because he is a very current skydiver, AFF instructor and has a couple of previous reserves). Anyway, when I had my one and only reserve some time later, the Skyhook beat me in opening my reserve. So I don't know about the 10%, but I do have reason to believe that a skyhook does not work always. So I'm not going to lower my hard-deck. Still glad I have it beacause it still might save my ass ;-)

    If you are still a student, as in just starting to jump.... Don't buy a helmet. Your DZ will provide you with one. If you want to get one after a couple of jumps: discuss with your instructors. Not every dropzone will let a student jump with a full-face helmet because of the reduced peripheral vision (especially some older types (of helmets)). In some cases, it makes it difficult to locate your handles.

    Sorry to disappoint you, but... I HAVE thought about it, because it was one of the very few points that climate change deniers made, that actually made sense to me. Turns out, their impact is close to nothing. "There is no doubt that volcanic eruptions add CO2 to the atmosphere, but compared to the quantity produced by human activities, their impact is virtually trivial: volcanic eruptions produce about 110 million tons of CO2 each year, whereas human activities contribute almost 10,000 times that quantity. " https://www.scientificamerican.com/article/how-do-volcanoes-affect-w/ Try again.

    I like your logic! Figuring out landings takes time and practice, but having good feedback from a canopy coach can really help to pinpoint potential errors in your technique. It is not just flaring too high or too low. It is also flaring too fast, too slow, not far enough. Many people let the toggles go before their landing is finished - and don't even realise they do it. Just to name a few things I have seen (or done myself). Reviewing outside video also really helps!

    I have nothing usefull to add, except: Impressive work, and keep posting because it's nice to see it!

    So surprised that people are answering this seriously. It has all the hallmarks of trolling, just surprised it's a xfire 1 and not 3. How many people with 26 jumps use 'fully elliptical' etc. Yeah you are probably right, but then again, I also did not believe Sangi was a real person Besides, some real person may be reading this thread, wanting to do something just slightly less moronic, and getting the impression that he is making conservative choices.
  24. evh
    I really hope you are just trolling. If not, the responses you have had so far are way too soft, Imho. Simply put, you should not be jumping a crossfire of any size and you should not be jumping any canopy at that wingloading.
  25. evh
    Bingo! Separation in this case is simply the distance the plane flew during the period between exits. When jumper nr 2 exits, there is a certain distance, calculated by air speed x time. This distance will still be there during opening.
