How bad of an idea is this...

Either way, do not put an AAD in any vehicle without turning it off, for more reasons that just this

has this ever happened? someone slamming a car door and activating an AAD?

It was determined that leaving the rig in his hot car caused the reserve to swell and contract on each day, resulting in the pin being pulled out a bit each time.

BULLSHIT! Rigs are left in warm places all the time. Probably close to a hundred are left somtimes weeks on end in the Video rooms at Eloy, and, I'll bet you good money those rooms get hotter in summer than your buddy's trunk.

Tell your buddy he probably jumped all day with a -almost- fired reserve because he didnt do pin checks. The other option would be that the handle/cable was jerked between the last jump, and his putting the rid in the car.

That's about the best fish story I've heard in skydiving.

If the pressure change during ascent and descent (several PSI) doesn't affect the pin, and the temperature change during ascent and descent (often 40 degrees or more) doesn't affect the pin, a car is nothing to worry about.

I've heard of car trunks only, not inside the car. But then again can't give you any places and dates so I suppose it could just be folklore, although I doubt it.

Gotcha...trunk seems more plausible....but I have a Jeep so Im totally immune from a freak AAD car firing

Vigil recommends turning off before placing your rig in your trunk due to air pressure variations:


From the http://www.vigil.aero/faq:

What are the recommendations when I travel in a moving vehicle (Train, Car, Bus...) ?

Vigil is the most accurate AAD on the market. It becomes operational in a zone of 150ft/46m above or under takeoff level. To avoid unexpected firing, you must switch OFF your Vigil before traveling in a closed vehicle (boot or trunk) due to possible air pressure variation.

However, there is no inconvenient to travel in an open vehicle at the drop zone altitude.

Temperature and pressure changes due to an enclosed vehicle sitting in the sun and the sudden release of the pressure when the trunk is opened.

Trunks are not sealed. The interior of a car is not sealed.

There is an outlet valve in cars that is typically located at the side of the trunk. The valve is hidden by the carpet of the trunk, and allows air from interior to exit by the rear wheel well. The valve (about 8x3 inches in area) will typically have some very light weight film to act as a one-way valve so that air can't so easily get into the vehicle. When you have the fan on, it makes it so that air travels from the front all the way to the back seats and then out through the trunk.

The pressure can still see a spike when you close doors, especially the trunk, but it is not sealed, and pressure can't rise due to being out in the sun etc.

People are sick and tired of being told that ordinary and decent people are fed up in this country with being sick and tired. I’m certainly not, and I’m sick and tired of being told that I am

Same thing with trucks, if you look between the bed and the cab, you can usually see the vents. On both of my Chevy trucks, there is 2 vents about the size he described with the 1-way valve in them.

How about motorcycles??

There is a big valve that allows air to pass freely from one side to another, this valve is located on and just above the riders neck.






Just fucking with yall, I got no problem with riders.

I'm mainly concerned with packing outside, in the shade, on the green grass.

Do it. Shade is best but if you're in the sun, just do it reasonably quick.

There's another hazard to deal with when packing in the sun... getting sunburned. Happened to me at a boogie a while ago

Not to mention that the reserve swelling would put pressure on the pin in a direction that is perpendicular to the pin. Moving the pin would require pressure parallel to the pin.

BTW, the increased closing loop tension would actually make it harder to move the pin!
