    Generally lower aspect ratio canopies (7 cells) have a thicker profile (brainfarting on correct term), making them fly a bit slower but have a slower stall speed and better stall recovery traits. Likewise, higher a/r canopies (9+ cells) have a thinner profile and need more speed to fly. They also tend to stall at a higher speed and dont recover from stalls as well as 7 cells. The trim, nose design and brake configuration/settings all help the manufacturer control the traits of their wings. Johnny --"This ain't no book club, we're all gonna die!" Mike Rome

    Its tough to say. The stiletto, one of the origonal "ellipticals" only has a taper on the 2 end cells. A safire is tapered on the 4 outer cells. Usually the term tapered or lightly elliptical means midrange canopy (safire2 sabre2 lotus ect.) The term elliptical or highly elliptical usually means higher performance (crossfire2 stilleto katana samurai ect.) Up until the safire1 I dont think many "elliptal" canopies in any sense were meant for anything other than experts. Now it seems manufacturers are moving towards more efficient designs for every type of jumper. Elliptical itself does not inherantly cover any kind of flight characteristics, only the shape of the canopy. Make sure you know what you are jumping before you jump it!

    I've used harness input on many canopies to increase the recovery arc. The harness turn is usually slower and allows the canopy to stay in the turn for longer, thus "increasing" the dive, as opposed to bringing it right around with a riser. Your right, though, the recovery arc is with no input. Johnny --"This ain't no book club, we're all gonna die!" Mike Rome

    Im not sure about the straight decent rate, but the safire2 has awesome glide and a very short recovery arc. You can make a lot of canopies not ground hungry (english?) buy just flying them. But the safire2 is a great mid range canopy. Johnny --"This ain't no book club, we're all gonna die!" Mike Rome

    I used to think that too, and it's true, if your not gonna pull. If you're gonna pull, then pull altitude is where you need the seperation. Now in most wind conditions, they are real close, but on a day with the wind at 2 different altitudes moving opposite of each other, the ground as a reference goes out the window (or the door).

    When I look out and see we are doing mach5 over the ground, I dont wait that long to get out. Johnny --"This ain't no book club, we're all gonna die!" Mike Rome

    When I jump, instead of looking at the group out before me, I look more at the spot and how much ground the plane has covered since they left (assuming the wind direction is fairly constant). Looking at the group before you is way too subjective cause they're moving, you're moving. Way too hard to tell. I look at the ground and for air traffic.

    I've gotta agree with speedy also. The 45 degree rule has absolutley no use at all in any seperation use. It is dangerous and should be abandoned all together. Time is the only factor to determine exit seperation. How you determine that time can be gotten from a few sources but they basicly come from one source. The difference between airspeed on jumprun and airspeed at opening altitude. The 45 degree rule tells you absolutely nothing. Johnny --"This ain't no book club, we're all gonna die!" Mike Rome

    When we do a 180 at my dz (2, sometimes 3 otters running) we offset the jump run at least 1/4 to 1/2 mile. We generally dont have high openers in the first groups so there is a bit of vertical seperation also. Johnny --"This ain't no book club, we're all gonna die!" Mike Rome

    What should have been said is that in "most cases" the ground speed is a good quick indicator and is much easier to explain quickly than the airmass at opening altitude. As long as you dont have wind going in 2 totally different directions, the ground speed is a good way to tell if you need to give "more" or "less" time between groups.

    I called both the LI dz's today and none had heard of anything. I guess there's been stranger things floating in our water! Johnny --"This ain't no book club, we're all gonna die!" Mike Rome

    I just figured it was the next logical step! But I still hope you'll come down, even if you let clint win again.! Johnny --"This ain't no book club, we're all gonna die!" Mike Rome

    Dude, you're my fuckin hero. So you gonna come down to the Ranch this august and de-throne Clint? Johnny --"This ain't no book club, we're all gonna die!" Mike Rome

    Yeah, there was no word on that. Johnny --"This ain't no book club, we're all gonna die!" Mike Rome

    warning: this is complete speculation. I was on the LI sound yesterday working with my GF and her boss. He said he had heard an announcment all morning from the coast guard that a parachute had been found off the south shore of long island and they were looking for a missing jumper. Anyone have any info about this? warning: this is complete speculation. Johnny --"This ain't no book club, we're all gonna die!" Mike Rome

    Covered by what? The "no warranty, written or implied" that every manufacturer puts with all their products? I've been closing my javys right left for 800+ jumps without a problem. I wont expose myself to a possible mal to conform with the manual on such a small matter when I know my way will work. But, to each his own! Johnny --"This ain't no book club, we're all gonna die!"

    I got them with my bev suit when I got it 4 years ago. Im not endorsing them, just that I got them. Johnny --"This ain't no book club, we're all gonna die!" Mike Rome

    I've found (on my canopy) that I do the flatest turn in pretty deep brakes and the turn done with the harness. Johnny --"This ain't no book club, we're all gonna die!" Mike Rome

    I've done 2 mister bills on my xfires and the openings were just as nice as my regular ones. Just gotta get a good grip for the very end of the opening and you're in fat city. Johnny --"This ain't no book club, we're all gonna die!" Mike Rome

    Saturday was really windy and monday it rained but we but up 48 or 49 otter loads at the ranch. It started to get bumpy and turbulent at around 2 til 6 from what i heard from the jumpers, I was busy slaving over pack jobs! Johnny --"This ain't no book club, we're all gonna die!" Mike Rome

    I'm not to sure about that. Companies are now closing off the noses of canopies to create an airfoil with less drag. An open nose creates a lot more drag than a closed one. The speed you probably felt was the canopy creating less lift (worse glide) than you might have felt on a zp canopy. Edited to add: My first canopy was a pd-210. I was a little over 1.1:1 and it didnt land me that well. I sold it to a smaller girl for $400 who said it did great for her. It got me in the air, though.

    I try my best to figure that out before the turn is completed. If im too low during the turn, abort the turn or if its not killer low, get the canopy on heading and see if I need input to plane out. If I was coming out and saw I was low I would start with toggle input and carve if I had to avoid something. I did see someone notice they were too low after a turn and they kindof threw themselves out from under the canopy, bounce of the ground (it wasnt a pound into the ground hit, just not enough time to get fully under the canopy) and continue to fly the canopy to a stand up landing. Most people thought he would be busted somehow but maybe that move saved him from digging his femurs out of the ground. Who knows. Johnny --"This ain't no book club, we're all gonna die!" Mike Rome

    From atair's website: Yes, spectra lines change dimensions slightly, but they are easy to inspect, wear, and have no tendency for breaking. As with any raw material, an engineer must design their product around the specific characteristics of that material. The Atair Cobalt is not overly sensitive to trim. When a Cobalt canopy is built it is actually not in perfect trim. After 40-100 jumps the spectra is broken in changing dimensions to put the canopy into a more perfect trim. Other canopies may go out of trim, ours go into it! A new cobalt flies great, and as you break it in you will only become happier with it. Johnny --"This ain't no book club, we're all gonna die!"

    If you buy a xfire2 you still have 31 days to change your mind after that. Johnny --"This ain't no book club, we're all gonna die!" Mike Rome
