How to measure out initial break settings..

[skip 0]

How does one measure out the initial break setting on a new canopy with no factory made marking? Can you just pull the canopy taught and then pull out a little excess for the break line? Once you have figured out where to set the break how do you insure that both sides are the same length – measure down from the cascades and make a mark?

I understand that once the initial breaks are set and the canopy jumped there might be some adjustments to be made, I am just curious how riggers determine the initial setting.

Thanks

There should be some sort of mark on the lower brake line that indicates the "factory" setting for the brakes. If that is not there, then please contact the manufacture and get the measurement to assist you and your rigger. Or you can play trial and error and possibly have some wickedly bad landings and possibly get hurt.

Thanks Dave.

Actually I think you guys are speaking of the toggle (full flight) setting.

Not to be confused with the brake(stowed) setting.


I know it is just a twist of words, but two entirely different things.

Yes, that is what I'm talking about. As I understand the original post, that is what the OP is talking about as well.

On the flip side, why would a 200 jump non-rigger be worried about where the actual brake setting is at? Most likely that person would be attaching their canopy and be confused about how to set the toggles. Atleast that's what I've run into time and again with low time jumpers.

What do actual riggers call the toggle setting(full flight)? What do you call the brake setting (stowed)?

Fortunately,many factory trim charts are available on line.
The brake setting is usually listed as "brake to toggle."

Yup – I found what I needed.

Thanks…

I agree with you , the brake setting is governed by the the finger trapped loop , its relative to high the lowest steering line is to the "A" line attachment. Mine is 8 inches only to my canopy. The toggle location is your personal thing. A student canopy usually has a big bow full toggles up to trailing edge. so it cant be stalled . If you were jumping Demos or Accuracy and needed to sink, you might even have it tucking the tail slightly. Or a person with short arms that never thought they got a good flare. You could just out a temporary toggle knot until its comfortable. The amount of drive lost is so minimal you would never know. At your state of jumping you want to take your canopy for a ride not it take you.Hope this helps,

True for some manufacturers and false for others.

Some other lines Like the "C" use a negative measurement.

That is something that one has to really look out for.

An example is on the Skymasters:

Full flight is measured above the "D" on all the different sizes using the inside steering line and the inside "D".

The brake setting is measured in comparision to the "C" with a minus number on all sizes except the 290 which that measure is above the "A".

Different manufacturers have many different methods of taking the measurements,so be aware of that when reading the charts.
