Cutaway under 100ft with skyhook?

Recommended Posts

A lot of incidents were caused by collapsed canopies at a very low altitude and many swoopers went in since a very sharp angle of entry leaves virtually no room for recovery, the results are always fatal. I believe that most of you have seen this UPT Skyhook promotion video with an example of two BASE cutaways under 100ft at around 11:42.

What do you guys think about the idea of cutting away at extreme low attitude and hopefully walk away unscathed? Is it worth the gamble?

Certainly not with a Skyhook. About 10% of them the hook releases.

The base "skyhook" video had slider down base canopies. If you want to plan your emergency procedures around that example I would think twice.

A cutaway that low is a pretty sure way to die. I would take a collapsed or spinning main over a reserve not yet flying any day. It is still going to give you more drag and more of a chance that going back to practically nothing.

Besides the real question is cutaway under 50 feet, because you are going to be much further down the gravity earth food chain by the time you respond to your hypothesized collapse.

To say what Doug said a little clearer, those ARE NOT normal reserve openings from 100'. They are reserve canopies packed with the SLIDER DOWN. IF you don't know what that means ask a base jumper. DO NOT BASE ANY OF YOUR EMERGENCY PROCEDURES ON THOSE VIDEOS. DO NOT CUTAWAY FROM ANYTHING AT 100' UNLESS YOU PLAN TO LAND WITHOUT A PARACHUTE. Pick a reasonable cutaway minimum altitude for you and your equipment. Quite likely that will be at LEAST 300' and probably should be higher. If lower the alternative is to pull your reserve WITH OUT CUTTING AWAY to get more nylon over your head.

If packed like a reserve is supposed to be packed they likely would NOT have opened. Also remember that this is a promotional video trying to sell SkyHooks and Vectors. Seek other opinions.

If what people above have said still doesn't resonate with you, pick a few local experienced BASE jumpers and get their opinion on jumping at 100ft.

Then ask them what they think of taking a slider-down rig to terminal.

Apologize for my ignorance but could you elaborate on the source of your information regarding supposed "10%" skyhook releases (for skyhook assisted reserve deployments). Seems a bit high;).

Just an estimate I've seen. Nothing more than that. The Skyhook needs to be able to release allowing for pilot chute activation when there is no cutaway. Sometimes it will release lanyard during a cutaway as well. Any MARD is just a fancy RSL and a backup device. It is not to be depended on as part of a plan for deployment. Just like any other RSL or AAD.

This may be true. A friend of mine once borrowed my rig, had a spinning mal and cut away. He claims the skyhook did not work, and the reserve opened when he pulled the reserve ripcord. I wasn't there so I'll take his word for it (also because he is a very current skydiver, AFF instructor and has a couple of previous reserves).
Anyway, when I had my one and only reserve some time later, the Skyhook beat me in opening my reserve.

So I don't know about the 10%, but I do have reason to believe that a skyhook does not work always. So I'm not going to lower my hard-deck. Still glad I have it beacause it still might save my ass ;-)

I just had a cutaway with a skyhook and it took 350ft to open. Even when the skyhook engages, you have to account for the time it takes for the reserve to inflate. You might get a slow or fast reserve opening ranging from 100ft to 500ft, and it's certainly not worth the risk.

If your friend had to pull the reserve manually then the RSL shackle was disconnected, assuming no rigging errors were made. Either way, this has nothing to do with a skyhook.

Personally I have had a cutaway where my skyhook became disconnected though (see attached pictures). Spinning main canopy and 'normal' RSL deployment resulted in a twisted reserve. But the twists were easy to get out and I'd still take a twisted reserve over no reserve any day :).

What YvonneWiggers said. Even if the Skyhook disconnects, the RSL system still functions as a normal RSL. Many people get Skyhook equipped rigs but don't take the time to fully understand exactly how the system works and what it does. The fact that it's all packed away where only your rigger sees it is the main cause of this. It's difficult to explain it in just words. Most people need to be shown the whole set up to understand it.

Based on his description I'm pretty sure this is not the case. He said the opening was not faster than his previous reserves on his own rig, which has an RSL but no skyhook.
He probably pulled the ripcord when the reserve was already out of the container.
But I was not there, and he had the reserve repacked before I could have a look.

But even so; RSL shackles do get disconnected sometimes, making a cut-away at 100 ft a pretty dumb decision.

I think it would be better to not put myself in an avoidable situation to make the "gamble".

You mention 2 things- canopy collapse and swooping so I'll address them separately.

1- Canopy collapse: don't jump in bad wind conditions and learn how to avoid turbulence from objects on the ground when landing.

2- Swooping: there are resources to learn the proper techniques when you have the experience. Don't just wing it.

This does not really answer your question (the plural of "anecdote" is not "statistics") but: My one Skyhook cutaway did not result in a MARD; it disengaged due to the angle I was at and acted as an ordinary RSL.

So sure, this is just a single occurrence, but there is no way you could convince me to cut away lower because I had a Skyhook installed. No way at all.

(I would still buy another Skyhook if the container I wanted offered the option - it's a good idea. But it's not magic, and it shouldn't change the decisions you should make when things go pear-shaped.)

To be clear for the sake of our newer jumpers, a cutaway at 100 feet is a bad decision regardless of the status of the RSL.

Yes agreed, thanks for the emphasis.
What I am trying to say is that you should not rely on an RSL/Skyhook (or AAD) at all, ever, when deciding on your harddeck. Because they may, and sometimes do, fail.
