    Ahhhhhheeeeemmmmm... The Parachute and HER Pilot thank you very much. Are you coming up to the ranch this year? Ohh, sorry. Try to get a hold of the 6 articles that ran in parachutist called the art of swoop survival. Very informative and gives a good plan for stuff to work on UP HIGH A LOT

    Its not directly related, but my GF recently got her CPR certificate, and she wants to try to get a bunch of kits on the dz consisting of rubber gloves and a mouth guard. It only takes a few seconds to protect yourself from bloodborne pathigens (whatever they are) and it can save you a lot of grief. She now caries a kit in her car where ever she goes. She also wanted to get a defib for the dz and her car. In the long run its relatively cheap for a dz and could easily save a life. Now someone can get back to the topic if they like.

    I dont know when it first happened or who introduced it, but Icarus has built that into their canopies claiming it creates less drag and a cleaner airflow over the canopy. All I know is I love (and loved) all my Icarus canopies. Good things tend to get picked up by everyone. Johnny --"This ain't no book club, we're all gonna die!" Mike Rome

    6 of one... Depends on you application (and probably your location, ie dirty) to which one works for you. Johnny --"This ain't no book club, we're all gonna die!" Mike Rome

    With out the ground, those little numbers are completely meaningless. Actually, without the ground, those numbers dont exhist. I believe that is why the ground is a factor. I might be totally wrong but I dont think I am stupid. I have been arguing over opening points, not seperation after a canopy has drifted away. For my point, I visualize throwing ballons filled with paint out of an aircraft over a ground that will show the impact points. Winds aloft or airspeed win not change the IMPACT POINTS. Only groundspeed of the aircraft will. Once each balloon leaves the aircraft, they are all affected by the same winds, be they in the same direction, every diferent direction, 100kts or 0 kts.

    I think Tom Buchanan (tombuch here) wrote a pretty good article about this subject. it can be read here: http://www.ranchskydive.com/safety/tb_article15.htm He brings the useable length of the jumprun into the equation. Johnny --"This ain't no book club, we're all gonna die!" Mike Rome

    If you trust the winds aloft you will know the seperation using the airspeed indicator. All this can be worked out on the ground and the exit seperation time can be worked out knowing the direction of the winds and jumprun. Johnny --"This ain't no book club, we're all gonna die!" Mike Rome

    Same uppers/ same direction on the same day Get out of an otter facing into a 70kt headwind 10 seconds after another jumper. Then get out of an otter with a 70kt tailwind 10 seconds after another jumper.(180 degrees from the first jump run) The first you could very well have a close call with. The second you propably will never see. Johnny --"This ain't no book club, we're all gonna die!" Mike Rome

    Again I dont think derek is arguing that jumpers dont move once under canopy. If you pull after 3 seconds and then hold into the wind, can he exit the tower? WE have been discussing opening points, not what happens after that. WE exit over a point on the ground, we open over a point on the ground, we land at a point on the ground, it is the reference by which we measure everything. You dont say "I opened over that mass of air over there" Yes jumpers move under canopy, but that would mean we would have to wait for there freefall to be over to be sure they would not be in the same point as we were planning to open. This horse is getting pretty damn tired of being beat. I think it was dead 3 pages ago, but I think we actually agree on most points, we just dont know it.

    Im pretty sure that would not be the thought going through my head. Online Im granted the guft of posting with some humor (albeit bad humor), so like I said I would go straight for the reserve. Johnny --"This ain't no book club, we're all gonna die!" Mike Rome

    I've been told that the cheaper trv models have small lenses (not a lot of glass) and they suffer from low light and changing light problems. Any truth to this. I am just starting to research my first camera and its a bit overwhelming. Johnny --"This ain't no book club, we're all gonna die!" Mike Rome

    We are always jumping, doesnt even need to be near 25 degrees! Our season pretty much starts in april. We are in the midsts of getting it all ironed out right now. We have our safety "weekend" usually on the first weekend in april, more jumpers around, lots of recurrency stuff for the fair weather folk who dont brave the snow. I think they might have something planned for march, but the weather usually doesnt permit much. We should have the schedule posted soon, so keep and eye out. See ya there!

    So the first jumper who opens facing up wind and colapses their slider and fumbles with their chest strap sees the second jumper scream past them when they pull 5 seconds late after they have a hard pull. Thats why I believe horizontal seperation is the only thing that matters. I look out of the plane to see how much distance the plane has made since the last group exited. I just think jumpers need to know the ralationship between the ground speed of the plane and the amount of time needed to be given between groups.

    I did 2 days with Jim and Clint around christmas and it was awesome. Definetly give it a shot! Johnny --"This ain't no book club, we're all gonna die!" Mike Rome

    Never, except at the end of the tube/impact point of the ground/opening point if the canopies dont move. Johnny --"This ain't no book club, we're all gonna die!" Mike Rome

    And if they were that would still give us the same amount of freefall drift and no (or not enough) opening separation. Also on days where the otter would have zero airspeed on jumprun, we would usually wait a considerable amount of distance past the dz, a usual "there is no too long" day.

    no it will land 45 seconds later in the same spot edited to change my time cause i misread your post. If someone has a slow moving canopy or turns back up the line of flight or opens off heading, its pretty damn close, especially when drift isnt static and things change in the air.

    Someone had to move out of the air. If you dont move you are basically a wind drift indicator. If you throw a wind drift indicator off a bridge (or plane in the air that doesnt move across the ground) and wait 2 minutes and throw another one, unless the winds have changed, they will follow the same path. I have exited an otter with almost zero airspeed after waiting 45 seconds (counted on video) and opened almost right were the group before me opened (the exact same space they occupied only a few seconds earlier). The distance the plane covers over the ground between groups is the distance the groups will have on opening barring differences in drift (rw, freefly, tracking ect) edited to add: and I am sure its me, but I dont see a way to make both fallers on Kallends program slow, only to put the faster faller out 1st or 2nd.

    I dont think he is trying to say that. He is saying that it is ground speed that determines how long a group has to wait in order to have a predetermined distance between groups at opening. once you leave the plane, where it is when when you open is irrelevent. After you leave the plane, the plane now only matters to those still in it. Johnny --"This ain't no book club, we're all gonna die!" Mike Rome
  20. johnny1488
    If groundspeed were irrelevent, then on a jump run into 70mph headwind with 70mph airspeed, you would give the same amount of time as you would if the pilot then turned 180 degrees and did another jump run at 70 mph airspeed. The entire first pass would open on top of one another and the second pass would be miles apart. It is groundspeed that determines the amount of time left in between groups.

    99% of the time at my dz we use an unpwind jumprun. If I needed to, without knowing the windsaloft, I could simply look at the ground speed and tell what kind of seperation I needed to give. The ground is the only thing that matters when giving seperation. Winds aloft really has no bearing because we are all subject to the same wind after we exit the plane. throw from the plane means nothing (with the exception of presentation to the relative wind, in which the effect is minimal). Look at Kallends simulator again. You could be going 500 mph through the air. If your groundspeed is zero, you will have zero seperation at pull time, period.

    That website doesnt look to me like they sell any cameras. Is that the right address? Johnny --"This ain't no book club, we're all gonna die!" Mike Rome

    I am obviously nitpicking, but I dont think PD makes a 135r. I think they have a 143r and a 126r. I am not sure about the other manufacturers. Johnny --"This ain't no book club, we're all gonna die!" Mike Rome

    My freebag costs about $150. Add a zero to that for my main. Plus I'ld hate to have on riser gone and one not. If my handle was anymore that out of the pocket, I would pull the reserve. Johnny --"This ain't no book club, we're all gonna die!" Mike Rome
