rredman 0 #1 March 29, 2004 I was wondering if anyone has ever seen a chart, or table, comparing altitude loss during a toggle turn on various canopies at various wing loadings? thanks, Ross Quote Share this post Link to post Share on other sites
billvon 2,898 #2 March 29, 2004 That would be difficult. Weight shift, amount of toggle turn, angle of turn, altitude, and time of toggle pull all influence how much altitude you lose. Why would such a chart be useful, in any case? Quote Share this post Link to post Share on other sites
rredman 0 #3 March 29, 2004 We are trying to display in very clear terms to students how quickly things change under smaller canopies. I realize that there are a lot of factors involved here. This would be more of a training aid to show students the effect of going to a small canopy. We already do lots of informational type training, telling people that a Sabre 135 will lose altitude much more quickly than the Manta 280, but it would be nice to put in in very graphic terms.

Perhaps a Neptune could be used to capture descent rate information while a jumper made four ever-more-aggressive turns up high. Afterwards look for the four dips and measure how long it took to resume level flight. Quote Share this post Link to post Share on other sites

JohnMitchell 16 #6 March 29, 2004 Pilot flight manuals have those charts that show how many G's are pulled for various angles of bank, which extrapolates into increased rates of descent for non-powered flight. It would probably take a lot more calculus than I remember to work it out, but it does give a hint of what's going oon in those radical turns. I wish you all the success in teaching canopy safety to the up and coming jumpers. It's way too dangerous out there these days. Quote Share this post Link to post Share on other sites
rredman 0 #7 March 30, 2004 Thanks for the encouragement. I am just tired of reading incident reports about things that should not have happened. Quote Share this post Link to post Share on other sites
