1. Is it there?
2. Is it square?
3. Can I steer it?
4. Does it flare?
If the answer to any one of those is no. Then chop it.

> the risers is it safe to land or should we cut away?
I teach "if it's most of the way down and the canopy is controllable, keep it." Most of the way down will vary from person to person. If it's stuck in the middle? Judgement call.

In the old days we used the "spit test". The idea is that a wad of spit falls at a rate which represents the maximum you can land safely without getting hurt.
I have also heard this one. Is there really any scientific basis behind it? Does it depend on the size of spit blob you can spit.
And I am asking seriously here.

Thanks for that John - I'd not heard before. I'll bear it in mind as a 'backup' to my normal thought process! I'll give this a try on my next jump (hopefully with a fully functioning canopy however !)

QuoteHay man, I just read you post and wanted to let you know what works for me in that situation. Flare the canopy and hold the toggles down, than pump at the bottom of the stroke, about 1 ft. usualy brings the slider down faster than just pumping the entire stroke of the flare. Understand what I'm describing?
thanks bro.. I appreciate the advice. I will try it when it happens again.

The "spit test" works well with round military parachutes, but not relevant to modern ram-air parachutes.

But personally if I had plenty of altitude and I wasn't descending remotely like a freefaller -- 4000 feet pull -- I know I'd try everything including everything that's said here including full toggle pump, deep toggle pump, pumping front risers, pumping rear risers, pumping opposite risers (left front/right rear), to attempt to stretch the slider in all kinds of orientations to get it to slip. One of these may put sufficient tension in the correct direction to undo a tension knot and get the slider to slide down. Assuming I had plenty of time and descent felt reasonably leisurely.
However, I won't be hesistant to chop if all else failed by hard deck and the slider was too high up for me to trust a good uneventful flare to...
I'm not an instructor though....I'm merely a 1-pie wonder....go talk to instructors...

I recall a Meteorology class I took in college, studying weather. There was a chart in the book about the terminal velocity of various types of things like rain, snow and hail. The bigger the raindrops, the faster they fall. But even the largest raindrops were within the normal descent rate of a round parachute, which was at worst, oh, about 15 feet per second. So that's the scientific basis for the idea.
As riggerrob mentioned, whether or not that still applies to a ram-air chute, is another question. It could be argued, I suppose, that under a ram-air, your normal descent rate may be greater than a spit ball, but as long as you can still flare at the end, it doesn't matter. And your forward speed is going to make it more difficult to observe the spitball, because it's going to fall under your legs and behind you.
You might try the spit test under normal conditions for your canopy as a baseline reference point. Then if you ever have a minor problem in the future, you can spit again, and compare results to the ideal reference point in your memory. It might give you some input as to how much trouble you are in...

Spit comes back to you, no matter which direction you fly in. Even when flying downwind, spit comes back to you.QuoteAnd if you spit and it comes back at you, you know you're flying into wind. Came up in a discussion i had about being in a bad spot and not seeing any references for wind direction.
Of course, you did include a smiley so I know you were joking....but newbies may not figure it out.
If the slider was much higher than that, wouldn't the end cells have a hard time inflating?
Sorry for the dumb questions, just want to make sure I got this right.
