Summary: An electronic logbook for skydivers with a web interface.
Sure, your paper logbook will be interesting to look into and reminisce about jumps that you did, but did
you ever consider that you could glean all sorts of interesting statistics from it? That is, datamine your
jumping career? And to make it extra interesting, throw in the logbooks of your jumping buddies too, and we
have a whole database we can play with! Neat! But that's not all, of course.
Current functionality: log in, enter logbook entries (like a paper logbook), and do all sorts of interesting
things with those logbook entries, like searching, doing queries on ranges of dates (like, how many jumps and
freefall time did you do between two particular dates), sort logbook entries by all sorts of criteria, find out
all types of airplanes you jumped out of, find out which are your maximum exit altitudes and minimum opening
altitudes, and a lot more stuff like that. There are still a few things that are biased towards Holland, like
the mention of the local parachuting association (KNVvL), for example. These can be easily customized if
There are more features on the way. Such as a "relative work" applet, which will give you a way to draw and
save points you made during a formation dive. There's a whole equipment section in the making. So, you'll be
able to keep track of your stuff: repack dates for your reserve, yearly checkup dates, serials, etc. Also more
detailed queries, linking various databases toghether (databases on different servers, that is), and lots of
other things. If you have any suggestions, please submit a feature request or email me!
This program is released under the GPL license. You may
use it free of charge, make copies of it, whatever. See the GPL license for details. I make no guarantees of
its usefulness or suitability. Use at your own risk. Bla bla bla
to try it out or create your own login to play with. The demo is to show functionality only. Please do not add
your entire logbook. This is meant so you can try it out before you install it on your own server or pester
your DZ's webmaster enough so they'll install it so your entire club can use it! :-)
If you want to run the Skydiver's Online Logbook on your site, you need a
MySQL database and a webserver which understands PHP. MySQL and PHP exist
on many different platforms, so a unix flavour is not required. This program was developed on a Red Hat Linux system, running the Internet's most popular webserver, Apache.
You don't need a high end system to run the logbook software. I expect it to perform well on a Pentium 200
even with many users. MySQL and Apache are both very efficient. :-)
Some alternatives I was able to find:
JumpTrack by Larsen & Brusgaard. Very cool, very
slick software to interface with your ProTrack. Also very
expensive, and still requires you to fill in a bunch of data, if you wanna keep track of that.
Skydiving Logbook by Duncan Sample. His is a variation on
mine. Still in development (as of 27-08-2002). Is looking very
SkyLog, which offers some of same functionality (a lot less
features, though), but is for a standalone PC, only has your own jumps in it (so you can't compare to your
fellow skydivers!!) and it costs money.
