Brand new ZP should be almost 100% impervious to air whereas brand new F-111 will be "leaky" right from the factory. There has to be an advantage of ZP over F-111 besides life-time.

(It's also not all F-111, that's a specific type of fabric that few manufacturers use nowadays.) Most non-ZP fabrics start out pretty tight; a PD150 flies a lot like a Sabre 150 at first. >When ZP fabrics wear out and become porous they are more similar to F-111 and >generally considered "ragged out". Again, not so much. PD did a study a while back on old ZP fabrics, and while some did increase their porosity*, most held up for thousands of jumps. In general, sun and packing damage will end a ZP canopy's life by making it too weak to withstand the stress of opening before it becomes unlandable due to porosity. (* - There have been 'famous' batches of fabric that had very specific problems, and some colors of fabrics fare better than others due to the inherent UV protection in their pigments.)

djro 0 #81 April 8, 2011 QuoteSure, but there is a limit to the differences in the canopy sizes that can be hobbled together in a rig. Really? How's that worked out? Quote Share this post Link to post Share on other sites

Fortunately, manufacturers are now starting to offer radically different sizings. You can get a rig designed for a 109 main and a 160 reserve nowadays, which goes a long way towards letting even competitive swoopers jump a reasonably loaded reserve.

lanceav8r 0 #94 May 30, 2011 I am going to respectfully disagree with this. If the FAA TSO'd parachute is certified up to a maximum gross weight than you cannot legally jump it above that weight. This is no different than flying an airplane over a certified max gross weight. This is not a manufacturers recommendation, it is a certification limit. However the reality is that the FAA could care less what you do. Their view is your an idiot for jumping in the first place. QuoteQuoteI know I have asked you this before, but why do you insist on referencing the FAA and American Law to people who do not live within their jurisdiction? What makes this even more interesting is he is totally wrong about FAA Regulations and American law. It has been covered in many threads, but there is absolutely nothing in the FAR's that pertains to exit weight and/or reserve wing loading. There is nothing in the FAR's that says you must follow manufacturers recommendations regarding wing loading. There is nothing in Sec. 91.13 — Careless or reckless operation that applies to operations of parachutes. In the USA you can have an exit weight of 500 lbs and jump any TSO'd reserve and not be violating any laws or regulations. No rigger will get in trouble and no pilot will lose their ticket. It is a bad idea to overload a reserve, but it is 'legal' to do so. Quote Share this post Link to post Share on other sites
mjosparky 3 #95 May 30, 2011 This is just my opinion of a very complex and vague subject. But I feel if you over load either you harness/container or you reserve you are in violation of FAR’s and the FAA can make it stick if the so wish. I do not think the FAA came up with the numbers just to give the manufacture something to fill in the blanks with. Sparky 105.3____ Definitions. Approved parachute means a parachute manufactured under a type certificate or a Technical Standard Order (C–23 series), or a personnel-carrying U.S. military parachute (other than a high altitude, high speed, or ejection type) identified by a Navy Air Facility, an Army Air Field, and Air Force-Navy drawing number, an Army Air Field order number, or any other military designation or specification number. Technical Standard Order Subject: TSO-C23d, PERSONNEL PARACHUTE ASSEMBLIES (2) The manufacturer must furnish to the user of the article one copy of the data and information specified in paragraphs c(l)(ii) and c(l)(v). This data and information is necessary for proper installation and use and for continued airworthiness of the product or article. “The conditions and test required for TSO approval of this article are minimum performance standards. It is the responsibility of those desiring to install the article either on or within a specific type or class of aircraft to determine that the aircraft installation conditions are within the TSO standards. The article may be installed only if further evaluation by the applicant (user/installer) documents an acceptable installation and is approved by the Administrator.” Note: Wording is often meant to apply to all forms of aviation not just parachutes.

mchamp 1 #96 July 13, 2011 I don't think this justify's a new thread so I'll ask it here, What max Reserve WL would you deem survivable/safe to land unconscious provided open flat terrain? I remember someone posted that 1.4 WL gave them a decent rate of 17mph with brakes stowed. If you haven't posted in the poll please don't post those stats there simply type the numbers here thanksFor info regarding lift ticket prices all around the world check out http://www.jumpticketprices.com/dropzones.asp Quote Share this post Link to post Share on other sites
stayhigh 2 #97 July 14, 2011 After jumping mine i wanted to lengthen my breakline by 2 or 3 inches on smart 120, loaded at 1.7 It was stalling when i was in full arm length, deep breaks chasing my main.
