    AAD: cypres vs. vigil

    Yes, I agree with you that any rig that is Cypres-ready is also Vigil ready, IF you follow the *entire* instruction that comes with Airtec's methods of mounting the AAD. In other words, if you decide to use Airtec's way of cutting the loop and place the cutter in the same position, you should *also* follow their recommendations with a thinner and more flexible loop. The point here is that Airtec did their research on this and found that there can be problems if you cut a 725 lb Spectra line at the bottom of a container. The length of the loop still runs through all the grommets in the flaps that hold the pilotchute back. A thicker and stiffer reserve loop can cause pilotchute hesitation in this scenario. In my opinion, the only sensible way to introduce a new AAD to the market and have any success with it is to use the same mounting method as Cypres. But then you must embrace the entire concept, not just parts of it. Or you can do all the research on your own and come up with something brand new, but that costs a lot more money and is not very likely to be accepted by the rig manufacturers. So, to give you a short answer, the problem is that there *is* no "Vigil loop". And the manufacturer of the rigs do not say that cutting the loop like Cypres/Vigil do is fine with an ordinary 725 lb reserve loop. And yes, I have seen both Cypreses and Vigils. In fact, I have taken both types apart as well as run them through some extensive tests in pressure chambers. I have been a rigger since 1997 so I have seen a few variations of AAD installations as well. /Håkan

    AAD: cypres vs. vigil

    The issue is not whether the cutter can cut the loop or not. I'm certain the Vigil cutter can chop right through the steel wire used for reserve handles, just like the Cypres cutter does. The issue is that thicker loop material is not compliant with all types of containers if you, for example, cut the loop at the bottom of the container. One example is the French Atom rig which must use reserve loop material that is even thinner(!) than the regular Cypres loop when equipped with RSL. Yes, there was an issue with this in the past. The point is that Advanced Aerospace Design has not done this research. They are piggy-backing onto Airtec's suggested mounting of the AAD but not following it through since they claim loop thickness that history has already ruled out is okay to use. /Håkan

    Your non-US country's reserve cycle

    In Sweden we have a 6 month repack cycle for the reserve and a 1 year cycle for complete inspection of the main, harness/container, and reserve. For a while we were looking to change the repack cycle to 1 year as well, but that didn't happen. The governing body is the Swedish Parachute Association, see http://www.sff.se/ Unfortunately, it's all in Swedish. However, do not hesitate to contact me for further information as I am a member of the "Rigging and Equipment committee". /Håkan Andersson

    PD line trims now on-line :)

    Excellent!! I've been waiting for this. The data for the Vengeance is lacking, though. I guess it's coming. :-) /Håkan

    How to implement "practice pulls" on throw-outs.

    Ahh, some pretty interesting ideas here. First of all, the dropzone that I have in mind makes about 6-700 student jumps a year where they would be doing these practice throw-out throws. I'm afraid we wouldn't win the "Friendliest neighbor award" if we threw that much newspaper around. What is this WDI material? Could someone please spell out the acronym for us non-English speakers.

    How to implement "practice pulls" on throw-outs.

    Sorry if I wasn't clear in my first post. I mean for the first few jumps when the JM releases the PC out the door in true JAD-fashion. If the student gear is equipped with a spring-loaded PC, a standard PRCP is fine, but I want the student to do a practice *throw* rather than a pull. I agree that having the student throw a real PC on the ground is the way to go there, but what do they do *in the air* on those first few jumps when they are not actually activating the parachute themselves?

    How to implement "practice pulls" on throw-outs.

    Using BOC-mounted throw-out PCs on student gear is not unusual for AFF. (A secondary JM handle is added that releases two sides of the PC pouch when pulled.) Now, assume that you want to train students using JAD. How do you go about arranging for a realistic "Throw-out practice throw"? I don't want to do the conventional ripcord thing where the student is trained to hang on to the handle. I want the student to actually practice a good throw. Granted, the old ripcords get thrown all over the DZ at times, but we cannot actually *plan* on throwing a dummy PC away on every jump. Any good solutions out there?
