LouDiamond 1 #3 January 8, 2005 where I think a body could make some pretty big bucks at is in logging software. We have several hardware and software solutions to track and record our skydives that are amazingly small compared tot he tasks they do. However, IMO, the current software solutions oout there are fragmented and you can't get a one stop solution.

PalletMan 0 #7 January 9, 2005 Ok, ya ready?? This would be cool: Software that would analyze all the individuals/groups, weather, aircraft characteristics, jump run, and landing zones to determine the best exit order (when and where). It would model each group's freefall, expected opening altitude, and canopy ride to ensure openings maintain good separation and everyone can make it back to the DZ. The software would not only make predictions, but be able to identify problems and suggest solutions. It would make sure groups open with good separation, and, if not, suggest a better exit order. It would also predict if someone is in danger of landing out (suggesting a better exit order). It would also model what would happen if someone has a mal (gets an open main low or reserve ride). Even better than that, the operator would simply enter the group data and let the computer suggest the exit order. Perhaps the computer will predict that there's no way to load the plane without someone landing out (which may be fixed if multiple jump runs are allowed) or predict that everyone will make it back but some won't if they have a mal. This would be an extension of John Kallend's Freefall Simulation (http://lensmoor.org/cgi-bin/chute.cgi). It would model groups, canopy ride, multiple jump runs, and be specific to the dropzone. It would model in 3D. The operator could import a satellite image of the dropzone. There would be three types of landing zones: green (on DZ), yellow (off DZ but suitable to land), and red (not suitable to land). They would draw polygons to represent green and yellow. Everywhere else would be red. From there they would enter everyone's freefall and canopy flight info. They'd have to define freefly, RW, Tandem, AFF?, and Wingsuit (others?) for freefall type. They'd have exit weights and intended opening altitudes. For the canopy ride, they'd have to define size/type of both main and reserve (other stuff?). The operator would enter weather data: wind speed and direction at all altitudes, air temp, others? They would enter exit altitude(s) and jump run direction(s) (maybe the jump run directions are suggested). They would enter other stuff I forgot or didn't think of. Once everything's set up, the computer would predict green, yellow, and red exit zones for each jumper. Exiting in the green zone will get that jumper back to the DZ. Exiting in the yellow, they won't make the DZ, but will get an out. Exiting in the red would be bad. Perhaps each jumper will have two sets of GYR zones (one for good main and one for malfunction). The zones would be visualized by extending the 2D polygons on the ground into 3D. Each jumper will have their one GYR zones. For groups, the green zone would be the intersection of every individual's green zone. The yellow zone would include at least one individual's yellow zone, but may include some individual's green zone. It would not include anyone's red zone. The group's red zone would have at least one individual's red zone but may include someone's yellow or green zone. The software would not only predict where people will open (to provide good opening separation) but predict where people will land. As such, it would have to have an accurate freefall and canopy ride model. Since this would be very difficult to model accurately (freefall: 3D model each individual's body with gear or generalize into height/weight/body type/expected freefall position; canopy ride: 3D model each individual's body under canopy and each canopy's flight characteristics by make/model or generalize into wingloading/canopy size/canopy type), some generalizations would have to be made. Whew! That's all I can think of for now. It would be fun to model a load where everyone does hop n' pops from 13.5 in a hurricane to see what county people land in. --ArtSky-div'ing (ski'div'ing) n.

MWGemini 0 #8 January 9, 2005 Wow. There are just waaaay too many variables there for that to be done, I think. Analyzing data is one thing, but predicting what 30 jumpers will do during freefall and under canopy is quite another. Besides, we already have systems in place that work very well. Why spend hundreds of hours writing a software program that will never be used? Mike Quote Share this post Link to post Share on other sites

LouDiamond 1 #10 January 9, 2005 You jest but there already exists something along the lines that you mentioned. It's known as PFPS(Portable flight planning software) commonly known as Falcon view. There are several sub programs in it (it's a suite), like CAPS(Combat airdrop planning software)among others that can do quite a bit of what you mentioned(excluding the obvious things like mals and other varibales that are impossible to determine). It will even put all that info as an overlay on sattellite imagery to boot. I don't see a skydiver using it any time soon as it has a learning curve and can be time consuming and it's simply more than a rec skydiver would use."It's just skydiving..additional drama is not required" Some people dream about flying, I live my dream SKYMONKEY PUBLISHING Quote Share this post Link to post Share on other sites

PalletMan 0 #15 January 9, 2005 Quote Wow. There are just waaaay too many variables there for that to be done, I think. Analyzing data is one thing, but predicting what 30 jumpers will do during freefall and under canopy is quite another. There are alot of variables but I don't think it would be impossible (I used to intern on casting simulation (pouring molten metal into a mold) software where they were solving upwards of a million equations with a million variables and that was over 10 years ago). The whole thing really hinges on how well you can model the freefall, opening, and canopy flight. I just have a feeling that could be done reasonable well. If you start with a 2D sim of one person and build from there it doesn't seem so daunting to me. I don't believe the week-end hacker is going to do it in a couple of months though. I think it would take a team (a dozen?) a couple of years or so to do it right. QuoteBesides, we already have systems in place that work very well. Why spend hundreds of hours writing a software program that will never be used? IF you could get the model right, it would be useful for large dropzones and boogies. It wouldn't have to replace the current system, just assist it. But, it would be fairly expensive to build and the return on investment may not be there. --ArtSky-div'ing (ski'div'ing) n.

PalletMan 0 #16 January 9, 2005 Thats cool. We need to extend CAPS to SAPS (Skydiving Airdrop Planning Software) As far as the learning curve, the way I see it is you'll need someone computer savvy setting it up and inputing alot of the data, but you could use anyone with basic computer skills at manifest to just pick the jumpers, put them into groups, and click Go. One interface could be dumded down to that level with another for more advanced users. I think it could be done. It just may be, like I just said in the other post, that it's too expensive to build making the return on investment not worth it. --ArtSky-div'ing (ski'div'ing) n.
