1 / 4 Cypress Fire?

Recommended Posts

Interesting stat - where did the numbers come from?

I wonder what percentage of those that fired were on student Cypres units? I might think that number would be higher because 1) Well, students and 2) Those rigs are used only a few times by a large number of different jumpers, so the likelihood of multiple fires / unit is much higher than an AAD that's owned by a single individual for a higher number of jumps (at least my hope is that there aren't too many jumpers out there who have multiple AAD fires).

So, that assumption above would skew it so that it's not one in four units, but that there are probably a decent number of units in service that have multiple fires.

I'm guessing 'loops cleanly cut' refers to 'in use units' not just a test unit sat there constantly cutting loops :ph34r:



I don't know if you are aware, but in order to give a CYPRES approval to a container manufacturer ,Airtec test every model at least 36 times. That makes at least 36 'loops cleanly cut' ....

And don't forget to add another 80 000 + Cypres 1 units to the equation :)

That is a recommendation from PIA and it pertains to all brands of AAD.s. The key word is recommended. I doubt that many manufactures have followed this protocol.


The intent of TS-112 is to provide a recommended test matrix for any Harness/Container manufacturer (TSOA holder) to complete in order to authorize installations of specific AAD’s into their products.

Hi Michael,

In the past, Airtec did all those tests for the manufacturers for free. This is no longer the case. However their testing procedures were the same as the PIA TS-112. I wonder why :)
What I'm trying to say is that if Airtec claim 22 000 'loops cleanly cut', I have no reason to doubt based on their history of testing rigs.

If I'm reading the stats correctly (22,000+ cypres fires and 79,000 sales) then we're looking at 1 / 4 cypress's being activated?

Does this sound right? It seems scarily high to me....?



Testing, testing, testing ..... and some more testing and also lots of demonstrations and some more demonstrations.

If even "only" 1/10 cypress's were being activated, and 1/10 of those was a real save, ...

I tend to agree with you. But their claim of “loops cleanly cut” I think is a dig on Argus.;)

The exact number of saves could be tracked at the timeof Cypres 1 when the cutters had to be replaced at the factory. Now it can only be estimated as they are replaced in the field. The guesses vary between 3000 and 4000 saves. Way more than 2000 are definitely confirmed.

22000 cutted loops seems pretty reasonable with all the testing taken into account., plus all those applications of the Cypres cutter which are not skydive-related.

I have a vague recollection of an ad from them in the late Cypres I days stating:

50,000 sold
1,000 saves

On the one hand I felt good with that many saves...

Until I looked around the DZ and realized there were over 50 people there, and (assuming everything else was true) therefore there was likely one person there that had failed to do the minimum to save their life... Good that who ever that was, was still with us... Bad that 1/50 need it...

Agreed.

Not to mention student rigs.
Or those who were saved and never came back.

Still while the AAD's are doing their jobs (and the incident reports from 1990-present) show that change) it seems like a high number of AAD's fire because someone didn't do their job.
