3 Ring Maintenance

[dropzonebum 0]

I was wondering if anyone out there might like to help me...I was after some input into an assignment I am doing for my aerospace engineering degree. I have to write a technical manual and I am planning on doing a brief guide to 3 ring maintenance. We all know how to do it but if you have just bought a sport rig for the first time, you might not be too sure. I want to aim my little manual at the newly A licenced skydiver who just bought gear about how and why we do 3 ring maintenance. This is a publication I wish to go hand in hand with a riggers advice and demonstration. Just after some input as to whether or not the idea is feasable and has some merit. Interested in a worldwide opinion. thanks :)

Sounds like you are trying to write something like a CSPA "Know your gear" seminar.
I have an outline for the CSPA seminar.
Unfortunately, Sangiro, I am not allowed to publish a CSPA document on the internet without approval from the CSPA Board of Directors. Besides, it is only an outline. The full show requires a rigger to fill in with diagrams, samples and lots of details.

Well, there's three main reasons for the why to do it that I can think of:
1) It's an opportunity to thoroughly check for any defects or damage.
2) Keep it clean. Small rocks, dust dirt can get on the release cables or in your three rings fouling the mechanism and leading to a hard or impossible cutaway
3) Nylon has a memory and needs to be flexed so it doesn't retain its "locked" shape when released.
Not sure how long your assignment needs to be, but there's not really too much to 3 ring maintenance. Might be hard to write anything lengthy about it.
Have a suggestion for another topic. Don't know if this subject fits your criteria but there's tons of aspects and material on it. Exit order and separation. You can get into freefall drift, speeds of descent, ground speed, wind speed effects, upwind, downwind, crosswind, curving jump runs, winds aloft at different levels, etc. You could write a technical manual on how to calculate separation time based on the different variables.

and
4) Become familiar with your gear and not look at it as some mystical 'black box'. It's fun to pull things apart, especially when you are allowed to do so - or maybe it's just an engineers thing

Check out Jumpshacks web site. John's got a whole article on 3 ring maintenance.
