At the time the activation altitude was set at 750 feet, about 4 seconds from impact. This was basically the last possible moment to give time for the reserve to deploy.<\/p>\n<p><\/p>\n<h3>Why so low?<\/h3>\n<p><\/p>\n<p>Cypres had to assume the worst-case scenarios when figuring out whether a given jump is a low-pull or a no-pull. The last thing any AAD manufacturer wants is to open the reserve just as a main was about to appear \u2013 two canopies out simultaneously is a very dangerous situation.<\/p>\n<p><img decoding=\"async\" alt=\"two canopies out \" src=\"https:\/\/www.skydivemag.com\/new\/wp-content\/uploads\/2019\/02\/\/0aa7da6d-dc57-4679-bc62-d58cdb59af60.jpg\"><\/p>\n<p>Imagine a skydiver in 2010. She intends to stick to the then USPA rules of \u2018initiating deployment\u2019 by 2,000ft\u2019. She sees someone else when flaring out of her track and sucks it down a bit. She has a slight pilot chute hesitation and an unusually slow opening. It\u2019s easy to imagine that she\u2019s roaring through 1,100ft with nothing useful out yet. She\u2019s dangerously low \u2013 but she hasn\u2019t really broken any rules, and she doesn\u2019t want her reserve to be released automatically. It\u2019s easy to see why Cypres chose 750 feet, and later manufacturers mostly followed suit.<\/p>\n<p><\/p>\n<p>When the first Vigil units were released, in 2003, the activation altitude was set at 750 feet, the company later raised its firing altitude to [an average of] roughly 850 feet. The first Vigil units included an option for the user to change the activation altitude; this could be used to land at a DZ with different elevation to the take-off zone, or to manually adjust the AAD firing height higher. In 2013, Cypres introduced an option to increase activation height (<a href=\"https:\/\/skydivemag.smallteaser.com\/article\/20131011-cypres-2-new-option\">here<\/a>). In the Vigil and the Cypres, these settings are permanent; you adjust the setting once, and don\u2019t have to touch it again until you change the battery in your AAD.<\/p>\n<p><\/p>\n<p>The Mars AAD activates at 885 feet and has an option (like Cypres &#x26; Vigil) to change the firing altitude for individual jumps, due to different elevation of take-off and landing zones \u2013 but not to amend it permanently. It has to be re-set every jump, which is not really practical.<\/p>\n<p><\/p>\n<blockquote><p>In the last 15 years there has been an average in the US of almost one fatality a year where an AAD activated the jumper\u2019s reserve but it did not fully open before impact<\/p><\/blockquote>\n<p><img decoding=\"async\" src=\"https:\/\/www.skydivemag.com\/new\/wp-content\/uploads\/2019\/02\/\/c6067369-7d3e-473f-9c4c-d9621bdc3811.jpg\"><\/p>\n<h3>Reasons to raise your AAD firing altitude<\/h3>\n<p><\/p>\n<h3>1, Low Reserve Openings<\/h3>\n<p><\/p>\n<p>The downside of leaving deployment to 750 feet is that in more recent years sometimes it\u2019s been too late. In the last 15 years there has been an average in the US of almost one fatality a year where an AAD activated the jumper\u2019s reserve but it did not fully open before impact*. The only antidote to this nightmare scenario seems to be to raise firing altitude. Some jumpers may still be pulling low now and then. But if you\u2019re not one of those &#8211; does it not make sense to raise the initiation altitude of your AAD accordingly?<\/p>\n<p><\/p>\n<p><em>*(Note, the above should be compared with a conservatively estimated 400+ total AAD Saves in the US in a similar time period)<\/em><\/p>\n<p><\/p>\n<h3>2, Sport Developments<\/h3>\n<p><\/p>\n<p>Many parameters have changed since the first Cypres was introduced. Containers have become smaller and more tightly packed. We deploy higher, our canopies take more altitude to open, and they lose more height in a malfunction. Freeflyers have greater wind speeds than belly flying, so burn through altitude if they lose awareness.<\/p>\n<p><\/p>\n<h3>3, Topography<\/h3>\n<p><\/p>\n<p>If you jump at a dropzone with a variation in surrounding altitude (eg, a valley, or beach next to cliffs) a difference in exit point could put you with insufficient altitude to open the reserve.<\/p>\n<p><\/p>\n<blockquote><p>a difference in exit point could put you with insufficient altitude to open the reserve<\/p><\/blockquote>\n<p><img decoding=\"async\" alt=\"USPA\/PIA Skydiver Advisory 2010\" src=\"https:\/\/www.skydivemag.com\/new\/wp-content\/uploads\/2019\/02\/\/7e56d9d4-3897-4269-a365-73a6b912cc84.jpg\"><\/p>\n<h2>History<\/h2>\n<p><\/p>\n<h3>LROs &#x26; Altitude<\/h3>\n<p><\/p>\n<h3>USPA\/PIA Recommendations 2010<\/h3>\n<p><\/p>\n<p>USPA discussed with the PIA Technical Committee a series of 9 fatalities where jumpers impacted without a fully open reserve, after AAD activation. These were dubbed LROs (Low Reserve Openings \u2013 a bit of a misnomer, they\u2019re actually Low Reserve NON-Openings). In March 2010 they released a Skydiver Advisory (<a href=\"http:\/\/www.pia.com\/images\/rocketlauncher\/PDF\/TECHNICAL_REPORTS\/PIA-TR-401LowReserveOpeningInvestigationReport91316.pdf\">here<\/a>, page 9), which recommended that jumpers review their decision altitudes and consider deploying higher than the recommended minimum of 2,000 feet.<\/p>\n<p><\/p>\n<h3>USPA Recommendations 2014<\/h3>\n<p><\/p>\n<p>In 2014, USPA raised its minimum opening altitudes from 2,000 feet to 2,500 feet, a move copied by most of the world. The BPA raised minimum openings to 3,000 feet, which has been standard in France for many years. Yet, how many of us made a conscious change in our critical activation altitudes? With opening at least 500 feet higher, we could reasonably raise our AAD firing altitude by 100 to 400 feet and build a bigger margin of safety at the bottom end, without affecting the top end (provided we are vigilant).<\/p>\n<p><img decoding=\"async\" alt=\"PIA Technical Committee LRO Report, 2016\" src=\"https:\/\/www.skydivemag.com\/new\/wp-content\/uploads\/2019\/02\/\/81163d4d-b3a9-4cb1-83ca-f5856ae7c17c.jpg\"><\/p>\n<h3>PIA Recommendations 2016<\/h3>\n<p><\/p>\n<p>Six years of investigations into LROs by the PIA Committee produced a report (<a href=\"http:\/\/www.pia.com\/images\/rocketlauncher\/PDF\/TECHNICAL_REPORTS\/PIA-TR-401LowReserveOpeningInvestigationReport91316.pdf\">here<\/a>), that considered <strong>6 possible LRO factors<\/strong>:<\/p>\n<p><\/p>\n<ul>\n<li>A \u2013AAD and Harness\/Container interface may be causing a delay.<\/li>\n<li>B \u2013 AAD initiated deployment sequence is somehow different than a manually activated deployment sequence.<\/li>\n<li>C \u2013 AAD activation altitude is not sufficient.<\/li>\n<li>D \u2013 Reserve container restrictive forces are too high<\/li>\n<li>E\u2013 Reserve pilot chute drag forces are not sufficient.<\/li>\n<li>F \u2013 Low pressure area (burble) creates an uncontrollable variable with regards to initial reserve pilot chute deployment and inflation.<\/li>\n<\/ul>\n<p><\/p>\n<p>Despite extensive investigations the committee was unable to establish equipment-related causes (A, B, D, E) and was therefore only able to make recommendations relating to C and F.<\/p>\n<p><\/p>\n<p><em>\u201cOver the last six years of discussion, committee deliberation, bench testing, development of customized load sensors, live testing and the combined efforts of some of the brightest contributors to our industry in modern times, the Committee Members have yet to locate evidence that supports or indicates a systemic or specific equipment design issue.\u201d<\/em> <strong>PIA Technical Committee<\/strong><\/p>\n<p><img decoding=\"async\" src=\"https:\/\/www.skydivemag.com\/new\/wp-content\/uploads\/2019\/02\/\/a758ac2a-6220-4d5c-8f32-ea95e12e1947.jpg\"><\/p>\n<h3>Examining the Causes<\/h3>\n<p><\/p>\n<p><strong>A \u2013 AAD and Harness\/Container interface<\/strong> <strong>B \u2013<\/strong> <strong>AAD initiated deployment sequence is different to manual activation\u2026<\/strong><\/p>\n<p><\/p>\n<p>A rig assembled with the incorrect loop length (too long) is an issue, yet we see a worrying trend in the field of loop lengths getting longer and longer. If a rigger packs a reserve and it registers too high on the 22lb pull test a common \u2018solution\u2019 is to lengthen the loop \u2013 but this brings its own problems. If the loop is too long it can be slow to clear the flaps, if it clears at all. Proper tension is very important.<\/p>\n<p><\/p>\n<p>Deploying the reserve by cutting the loop is a different initiation to open the reserve container, compared to pulling the pin via the reserve ripcord or MARD. The pin is situated on the top flap of the reserve, releasing the pressure for a faster deployment. On the other hand, the AAD cutter is in some containers (but not all) placed at the bottom of the rig\/pilot chute. If the AAD fires, it cuts the bottom of the loop. This leaves most of the loop in place \u2013 and that (often long remaining loop) may have to snake its way out through the grommets in the flaps for the pilot chute to launch. The problem is compounded if the pilot chute adds pressure from below, jamming the loop against the grommets. If the loop is too long and the grommets are not perfectly aligned above each other it can create a hesitation of a second or more, necessary to initiate the reserve opening in time.<\/p>\n<p><\/p>\n<p>For this reason, CYPRES recommends the cutter is placed above the reserve pilot chute, on containers with internal pilot chutes. Similarly, Cypres recommends lubricating the reserve loop with manufacturer\u2019s silicon, to assist the remainder of the loop to clear the grommets from the inside of the container, after an AAD fire.<\/p>\n<p><\/p>\n<p>All the above could take fractionally longer than a manual deployment \u2013 especially when combined with other factors such as <strong>Cause<\/strong> <strong>D, Restrictive reserve container<\/strong> and\/or <strong>Cause E, insufficient reserve pilot chute drag<\/strong>. Raising AAD activation altitude gives more time in case many factors align to slow down the opening. The majority of LRO fatalities had a reserve beginning to inflate on impact; there was not enough time for complete inflation.<\/p>\n<p><\/p>\n<p>An eyewitness account (from a very experienced, highly qualified person) of an AAD firing just <em>before<\/em> the jumper pulled the reserve handle reported that <em>the reserve pilot chute did not appear until after the jumper pulled the handle<\/em>. This supports the theory that AAD initiated deployment is different (slower) to pulling the pin.<\/p>\n<p><\/p>\n<p><strong>Cause C, AAD Activation Altitude not Sufficient<\/strong> The committee agreed that raising AAD firing altitudes was a logical step to provide an extra margin of safety to offset unplanned variables.<\/p>\n<p><\/p>\n<p><strong>Cause F, Burble<\/strong> The report\u2019s recommendations for cause F were to reinforce the advice in USPA\u2019s SIM: after deploying the reserve, look over your shoulder or be head-high, to help the reserve pilot chute launch into clean air. <em>You can\u2019t do this if you\u2019re unconscious!<\/em> This is one of the main reasons many skydivers wear an AAD. The burble problem would probably not exist if unconscious \u2013 but it still seems the only realistic preventive measure in this AAD firing scenario is to address Cause C by raising activation height.<\/p>\n<p><\/p>\n<p>\u200b<\/p>\n<p><img decoding=\"async\" src=\"https:\/\/www.skydivemag.com\/new\/wp-content\/uploads\/2019\/02\/\/d9d170ca-d815-4537-8aeb-fff972bdd7a2.jpg\"><\/p>\n<h3>Possible LRO Factors<\/h3>\n<p><\/p>\n<p>USPA stated many possible contributory factors to LROs (below).

If you elect to change your activation altitude, refer to the Owner\u2019s Manual AND check with a rigger. You must pay close attention to your opening altitude (as always) and revisit your hard decks for decision-making and EPs.<\/p>\n<p><\/p>\n<h3>2, Low Puller?<\/h3>\n<p><\/p>\n<p>If you find yourself sometimes opening lower than the recommended height, an upward change could put you at risk of a 2-canopy out situation.<\/p>\n<p><\/p>\n<h3>If you decide to raise the firing height, how far?<\/h3>\n<p><\/p>\n<p>Like everything to do with your safety, it\u2019s a personal decision with no single easy answer. It is each jumper\u2019s responsibility to have a fully open main canopy well above activation altitude. The <a href=\"http:\/\/www.vigil.aero\/wp-content\/uploads\/Vigil-II-users-manual-II.0.6.pdf\">Vigil Manual<\/a> (page 16) recommends allowing approximately 1,000 feet between a <strong>fully open<\/strong> main canopy and the activation altitude. The<a href=\"https:\/\/downloads.cypres.aero\/userguide\/\"> Cypres Manual<\/a> does not make any recommendation on altitude, but includes instructions on changing activation altitude (pages 30-33). If you elect to make any change, get a second, qualified person to watch the procedure as a double check.<\/p>\n<p><\/p>\n<h3>And finally<\/h3>\n<p><\/p>\n<p>Do not rely on AADs to save your life.
