allrightscud 0 #1 July 20, 2001 Is there any problem with taking a cypres on a plane? I know its all suposed to be sorted out, but is there any airline which is particularly bad or good about them. Do you have to inform them at the time of booking?S'later Quote Share this post Link to post Share on other sites
phastasphuk 0 #2 July 20, 2001 should not be a problem anymore...well, maybe with american airlines, hehe...and look, I found this nice link!!!http://www.dropzone.com/news/CYPRESacknowledgedtobeno.shtmlchrisHow would you like too stick with meHow much do you love to freefall Quote Share this post Link to post Share on other sites

Do you have to inform them at the time of booking? There shouldn't be any problem.. Take your rig(in a gear bag, preferably) as a carry on.. DO NOT volunteer any info regarding what is in the bag except to security personnel - and then only if asked.. Don't make a big deal out of it, and everything will be cool..Mike Quote Share this post Link to post Share on other sites
Zennie 0 #4 July 21, 2001 I just travelled to Indianapolis from Houston a few weeks ago on Continental and had no problems. I agree with Aviatr... carry it on. You don't want them losing a $5000 piece of equipment.Security at both airports didn't even ask me anything. Just ran it through the X-ray machine and moved on. Had people on the planes say "that thing looks kind of like a parachute" and of course I said "it is". Nobody seemed bent out of shape, more intrigued than anything.As far as the Cypres goes, just make sure it's off and you won't have any problems. If security makes you turn it on, just remember to turn it off again.Oh, and get this, Southwest airlines (I'm pretty sure it's them) won't let you sit at an exit seat if you are carrying a parachute. What, are they afraid we're gonna yell "DOOR!" mid-flight? Have fun!------------Blue Skies!Zennie Quote Share this post Link to post Share on other sites

Aviatrr 0 #7 July 21, 2001 Quote Make sure it is off,they have fired when they depressurize the plane.Ok I admit it, it happened to me.Forgot to turn it off.I heard it pop when it fired. This must have been a fluke.. The cabin normally does not depressurize until within 200ft of the ground - and when it does, it just descends at the same rate as the airplane.. Cabin climb/descent rates when pressurized are normally 200-400 feet per minute.. The CYPRES requires a vertical speed of about 6800FPM to fire(which is 78mph).. If an airplane is descending at over 6800FPM within 1000ft of the ground - your CYPRES firing is the least of your concerns.. When your CYPRES fired, did your eardrums nearly burst at the same time? Only thing I can think of is either; A) the pressurization system did something really funky, which you would've felt in your ears and everybody would've been complaining and/or screaming, or B) your CYPRES screwed up and fired with a much lower vertical speed than required..Mike Quote Share this post Link to post Share on other sites
phastasphuk 0 #8 July 21, 2001 I've heard that you can take your gear as carry on, but you have to leave it up front with the pilots...maybe not to scare other passengers or to give 'em stupid ideas, or keep you from 30000 feet of freefall...and if you see the pilot running down the cabin with your gear, you're phuked.And I recently saw "charlies angels" onboard a flight, some scenes were missing, guess what scenes?! maybe for the same reasons...chrisHow would you like too stick with meHow much do you love to freefall Quote Share this post Link to post Share on other sites

Uhh, yea, that's the ticket.. You have to leave your gear up front with us pilots.. Check your rig at the cockpit door, you can pick it up when you get off the plane.. You'll never see us running down the cabin with your gear.....we'll just use the cockpit escape hatch.. You won't know we're gone until it's too late..

DZBone 0 #12 July 23, 2001 Quotebut you have to leave it up front with the pilotsIn case you didn't get the sarcasm in the other posts...Um, no.None of the airlines I know of have a problem with bringing gear on board. I travel frequently with mine, and have never even been asked about it (except as piece of luggage - couldn't take two on once - omigod, do I trust them more with my gear or the laptop?). My regular-sized gear bag with one rig in it (and all the other junk I haul around in it) fits nicely in the overhead.I haven't had to use it yet. Good thing, as I don't pack a bail-out bottle, acetyline torches, or a full kevlar body suit. Carl Quote Share this post Link to post Share on other sites
GrumpySmurf 0 #13 July 23, 2001 I thought aircraft cabins were pressurized to 7000 feet MSL? So if the airport (like SFO or YVR) is sitting at or near sea level and the plane 'depressurizes' from 7000 to 200, it could cause a CYPRES to think you are in freefall (especially a Student model)?? Just curious if the hypothesis makes sense? Quote Share this post Link to post Share on other sites
skymedic 0 #14 July 23, 2001 they are not all pressurized to 7'000 MSL. pressure inside depends on the altitude they are flying at due to the simple fact that you can only pump up a cylinder so much before it will POP. and if that happened then yeah, you would get a cypress fire. other wise the chance of it happening while in a commercial airliner is slim.MarcA-38578 Quote Share this post Link to post Share on other sites
phastasphuk 0 #15 July 23, 2001 Why would one keep their cypres switched on, except for sheer laziness. And I would like to see a cypres save from a commercial airliner. Imagine that, 30000 feet, plane cracks up, you go for the gear in the overhead compartment, bailing out from the debris, putting it on in freefall and you bounced cause of a no pull! damn, didn't forget to switch of my cypres is your last thought...Sorry, just mumbling here in my corner of the world. Keep 'em on and off at the right time, then all is goodchrisHow would you like too stick with meHow much do you love to freefall Quote Share this post Link to post Share on other sites

Just curious if the hypothesis makes sense? Not all aircraft are pressurized to 7000'.. It depends on the type of airplane and the altitude the airplane is at.. Each specific type of airplane has a maximum pressure differential(measured in PSI) between inside and outside pressure.. Some airplanes may have a cabin altitude of 5,000ft while at 37,000ft, others may have a cabin altitude of 7,000ft while at 37,000ft..While climbing and descending, the cabin pressure altitude will be doing the same - but at a much slower rate than the airplane.. Typical cabin climb/descent rates are about 300FPM.. Even a Student CYPRES requires 2500FPM to fire(which equals 29mph).. A Tandem or Expert CYPRES requires about 6800FPM to fire.. If the cabin altitude is descending anywhere near fast enough to fire even a Student CYPRES, there is definitely something wrong..Mike Quote Share this post Link to post Share on other sites
