Cypres fire during swoop?

Recommended Posts

I heard that 1 of the Babylon guys at Ampuriabrava (Spain) had a Cypress fire during a swoop recently. Apparently he came out of his 1080 turn on his velocity 79 and his Cypres 2 fired. He landed OK under both canopies.
Has anybody else heard about anything?

A 1080 is not necessary to reach canopy terminal veloicity. Spinning around and around will just make you dizzy.

The only way to make your Cypres fire once you have deployed is to go back into "freefall" for LONG ENOUGH. It is not necessary to dive your canopy for that long to reach maximum speed. If you stick to 270's, you will not fire your Cypres.

To be more precise, the only way to make your cypres (Expert) fire after deployment is to exceed a vertical speed of 35 metres per second. For a student cypres the speed is 13 m/s.
Edited to add: Of course this has to happen at the appropiate height.

I believe on the nitro 58 they were getting around 32 m/s vetrical speed when diving the canopy.
The article is in German http://www.hipercanopies.de/News.html

I would be interested to hear more about what happened in Empuriabrava.

Throwing 1080's might look cool and be fun once in a while to scare whuffos (or yourself), but they are far from accurate and are simply vanity turns that "beer line" swoopers perform. That being understood, the possibility that this guy made his CYPRES fire is entirely possible if he initiated the turn high enough. Troy Ketsdever did a series of tests a while back and got one (in a hip bag he wore) to fire.

Do you remember the concluding paragraph in my Cypres fire article? Here it is verbatim:
"If you are jumping a highly loaded cnopy and are using a CYPRES (or similar "expert model" AAD), consider carefully your landing approaches."

As would be expected, there was a lengthy letter to the editor written by a representative of Airtec published in the following month's Skydiving magazine basically questioning the validity of my testing methodology. I wrote a response to that letter defending my results, but it was never published, so I guess Airtec got the last word.

Regardless of the accuracy of this particular account, I stand by my conclusion that high performance turns and AAD's are a dangerous combination.

I would appreciate it if anyone could put me in touch with the jumper and the rigger who inspected the equipment for the event described in the OP.

Another interesting factoid from my article (09/2003 issue of Skydiving, BTW). The max calculated descent speed I reached was 84 MPH on a VX 86 loaded at around 2.6:1.
