meursault 0 #1 June 17, 2004 Hola! I'm curious how the high altitude jumps are made. I mean - what kind of plane you use, is the plane pressurized and how you open the door when the altitude is 10000-12000 meters? Quote Share this post Link to post Share on other sites
meursault 0 #2 June 17, 2004 I'm asking this, because a friend of mine is buying Cessna Citation X and we wondered if it's possible to jump with this plane from about 10000 meters. Quote Share this post Link to post Share on other sites

Yes, but for the cost of removing the aft baggage door on a X, it wouldn't be worth it. You would have to get FAA approval to fly w/ the door removed, which may not be possible. I know several DZ's that ioffer high altitude jumps. Last I heard Skydance charged $100 for one. Derek Quote Share this post Link to post Share on other sites
meursault 0 #4 June 17, 2004 Thank you, Derek. What you mean is that the plane doesn't have to be pressurized, only the pilot cabin? Quote Share this post Link to post Share on other sites
larsrulz 0 #5 June 17, 2004 Given his friend is buying a Citation X......I'm not sure if money is an issue....yet I wonder if they realize that one flight will cost at least $1500 just for fuel! Why not just fly to the US and do an actual HALO jump. I got a strong urge to fly, but I got no where to fly to. -PF Quote Share this post Link to post Share on other sites
larsrulz 0 #6 June 17, 2004 The pilot cabin also doesn't have to be pressurized (not at 10Km), but it is certainly nice to have some level of pressure differentiation for the pilot, much like military jets use. The only thing necessary to keep that pilot flying is oxygen. Would be nice if (s)he had some altitude chamber work too. I got a strong urge to fly, but I got no where to fly to. -PF Quote Share this post Link to post Share on other sites

It would depend on your governments aviation rules/regulations whether an a/c of that type is even legal to jump. Some countries can be severely restrictive. As far as the X is concerned, door position/exit would be interesting. As for pressurization, do a search on "HALO", and I'm sure all your questions could be answered regarding A/C depressurization schedules, oxygen "prebreathe" requirements prior to takeoff, O2 use during flight, and necessary O2 requirements for freefall. I've been on many, many military HALO drops as the "oxygen equipment tech" on-board.... Good luck, Buck Quote Share this post Link to post Share on other sites
ZMullins. 0 #8 June 17, 2004 at west tennessee skydiving we do high altitude jumps at 30,000ft and it onl takes 20mins to get to altitude and we dont pressurize the plane we just se oxygen all the way Skydiving, a sport you can fall for. Quote Share this post Link to post Share on other sites

JohnMitchell 16 #10 June 17, 2004 The Citation jet, and most aircraft, does not have a pressure bulkhead between the cockpit and the back compartment, so you cannot pressurize the cockpit by itself. The pilots will have to stay on oxygen the whole time, and dress really warmly. The citation has a high airspeed, and rear mounted engines. Slowed down it will be at a nose high angle. Are you sure you want to jump out in front of that big jet engine under those conditions? People have hit the airplane under better conditions than that.

JohnMitchell 16 #11 June 17, 2004 i think with Cypress, you must not pressurize the Aircraft, or you can reset the "Ground Level" to a higher value. You should probably keep the AC depressurized the whole time. Quote Share this post Link to post Share on other sites
174fps 1 #12 June 17, 2004 4 years ago we jumped a Fokker cargo plane from 18000' at the Kamloops boogie plane was pressurized , then slowly depressurized before our jump, had cypres and protrack both worked fine. Andrew Quote Share this post Link to post Share on other sites
Beerlight 0 #13 June 17, 2004 Hey Zach, Do ya'll breathe 100% oxygen on the ground before takeoff? ie. prebreathe Buck Quote Share this post Link to post Share on other sites
