The best system for Instructor and Student

• Through years of development and testing, the Sigma series of Tandem equipment is now the best and safest Tandem system we’ve ever produced.
• The comfortable harness and head-high free-fall position are great for the Instructor, and our Student harness is the most sophisticated and comfortable money can buy.
• Superior pin protection, retractable release handles, user-friendly component replacement and our Patented Disc Release system are just more ways that put us ahead of the competition.

Standard Features

Your brand new Sigma, or Micro Sigma, Tandem system comes loaded features, including: adjustable student harness, Magnetic Riser Covers, adjustable container harness, Double Wide Legpads, Retractable Release Handles, Spectra Reserve Ripcord, Reserve Pin Window, and our Skyhook RSL.

THE ADVANTAGES OF THE SIGMA TANDEM

• It takes fewer steps, with fewer potential errors to close the main container.
• Accidentally snagging the drogue bridle will not open the container.
• Out-of-sequence deployments are virtually eliminated.
• Its center-of-main-container drogue connection gives a more “natural” and comfortable droguefall position.
• The drogue release ripcords are automatically retracted after use, or accidental snagging, so
  that they are always where they should be, cannot be lost, and don’t have to be stowed after
  pulling.
• It has two redundant drogue release ripcords, one on the right and one on the left.
• The drogue release/container opening pin is “locked” until you throw the drogue, minimizing
  the possibility of accidental high openings.
• No more time-consuming untwisting of drogue kill line during packing. Kill lines can be easily
  replaced in the field. You still get a more or less normal deployment if the kill line breaks, and
  you don’t lose your drogue.
• Main deployment bag design reduces canopy damage.
• Student harness that is safer and more comfortable for students.
• The Skyhook RSL system.
• The “Collin’s Lanyard,” and all of it’s advantages.
• Tuck tab style reserve pin cover.
• Magnetic riser covers.
• Clear plastic windows make reserve pin checks and AAD operation easier.

GENERAL

The Sigma II Reserve is a modern 9-cell slightly tapered ram-air design that fully compliments UPT’s Sigma Tandem System. The SR’s maximum weight limit is higher than the legacy VR-360 tandem reserve. This reserve canopy is designed to open, fly and land far more like a tandem main parachute than a traditional reserve.

Following years of development and refinement, the Sigma II Reserve in both sizes (340 & 370 sq.ft.) has met and/or exceeded the required test standards of TSO-C23f.

The primary goal of the Sigma II Reserve tandem canopy developmental program was to provide an even higher level of safety to the tandem skydiving community. After many years of development and drop testing UPT is confident that the performance and reliability of this reserve parachute will speak for itself.

PACKING

Ease of packing by certificated parachute riggers was a consideration throughout the development of the Sigma II Reserve Parachute. The introduction of a cascaded Vectran line set means easier bulk distribution and a reduction in overall pack volume compared to the continuous Dacron line set used on the VR-360.

The modern planform design of the Sigma II Reserve is slightly tapered at the leading and trailing edge which makes parts of the pack job stack staggered at some locations. To aide in packing organization UPT use alternating white and black line tabs to easily identify line groups. The recommended packing method is pro-pack style reserve, see the manual for detailed packing instructions.

OPENINGS

Sub-terminal openings are typically soft and comfortable, with a short snivel and an even, progressive inflation that develops from the center to the outboard cells. Terminal openings typically involve light to moderate snatch forces, with signs of a brief snivel, before progressing into an inflation that is quick but not hard.

Tandem reserve deployments are unique in that they can occur from an inflated main parachute with a very low speed SkyHook deployment or from the very high speeds of drogueless tandem terminal. The Sigma II Reserve development specifically took this broad speed range into consideration to provide an opening that meets the altitude or time loss requirements specified by TSO-C23f. Careful attention was placed on minimizing opening forces for safety, especially in the high-speed spectrum.* Test jumps also included deployments with several induced line twists, where it was found that the Sigma II Reserve opened and inflated at generally the same rate. With reasonable body position, it remained centered overhead with no tendency toward diving or losing additional altitude.

* IMPORTANT NOTE: The FAA requires reserves to be tested beyond their placarded weights and speeds to provide an additional margin of safety. The Sigma II Reserves have been tested per the FAA’s requirements; however, you should NEVER exceed the maximum placarded weight for a reserve or deploy it at a higher airspeed than the maximum placarded speed. The deployment time and altitude described in the TSO should not be used to determine a minimum safe altitude for reserve deployment. You should always perform emergency procedures at or above the minimum altitude recommended in the Sigma Tandem Manual and Instructor Training Course.

FLIGHT CHARACTERISTICS

The Sigma II Reserve has a slightly flatter glide than the VR-360. Descent rate and glide more closely resembles that of a similar-sized main canopy than other reserves.

The Sigma II Reserve has an overall intuitive response to control inputs. The Sigma II feels similar in toggle turns to a tandem main canopy of the same size, making the control range more familiar and easier to adapt to.

The Sigma II has a fairly long control range for a reserve parachute, with excellent slow flight
characteristics. The stall point is very deep for a reserve, so much so that it may be possible to fly at full arm extension for a few seconds prior to getting a stall. Altitude permitting, it is best to check the control range, i.e. practice flares and braked flight performance of the Sigma II prior to landing.

The Sigma II Reserve is designed to minimize toggle effort while maximizing the flare power on landing. Customers will find that the increase in flare power and familiar toggle stroke make the Sigma II Reserve’s landing performance and predictability more closely resembles that of a main parachute.

The canopy responds directly to proper flare input. The beginning of the flare is easy to find, starting around mid stroke. With the long control range and powerful response, it is easier to land well, with timing of the input being less critical than for other reserve parachutes of similar size.

*Exercising proper skill and technique will result in a flaring must be timed well. Regardless of how great the flare potential is with the Sigma II Reserve, a hard landing will be the likely result from a poorly timed flare.

THE WORKHORSE OF YOUR TANDEM OPERATION

The A2 is an elliptical 9-cell canopy, built completely from ZP fabric to maintain consistent performance. Its airfoil and moderate planform factor guarantee superb handling characteristics, to minimize the workload of tandem masters.

Not only will they find the toggle pressure, turn response and flare power they have been seeking, but they will be pleasantly surprised by the soft on-heading openings.

The turn recovery and ability to slow the canopy in no wind conditions are additional features that will be greatly appreciated by all tandem masters.

The A2 is equipped with Spectra suspension lines which make for considerably less bulk and a more compact container on their back. With their lower weight the Spectra lines also reduce the risk of line dump and subsequent premature opening of the deployment bag, a significant cause of malfunctions.

Aerodyne have designed this canopy to maximize safety, but at the same time they made it an economical tool that will maximize the number of jumps per day. To reduce packing time, they chose a hybrid construction and added color coded line attachments.

To reduce air time, Aerodyne built a wing that will fly slowly in brakes, but gives you a significantly higher rate of descent when flown at full glide.

The A2 comes standard with Spectra 1500 lines, a slider with “super lightweight” stainless steel grommets, and #6 stainless steel rapide links. Naturally the A2 is compatible with all tandem harness-container systems on the market today.

If durability, flight characteristics, and efficiency are important, while maximizing tandem safety and enjoyment, the A2 can offer an unbeatable combination. All of this coupled with the world’s most stringent quality control standards (ISO 9001) and an unparalleled investment value in a tandem canopy.

It is the tandem canopy you have been looking for but could never find, until now.

The name Twin is there for a reason. As we started to develop our own Tandem canopies, we spent a lot of time defining their performance envelope, based on the requirements of passenger and pilot. Especially the suspended weights, which will not change as the tandem pair has to transit from main to reserve, convinced us that main and reserve needed to be identical. Twins, alright.

The new Century Versions of our popular Twin series are all of a eliptical planform, with a rather mildly swept back leading edge to enhance onheading openings and resemble so called hybrid constructions with ZP top panels. Vectran lines and stainless steel grommet come as a standard.

Twin Century 402

The largest size of the family. It’s design reaches back to 1996 originally marketed as a straight 9 cell made of all 1.1oz ripstop nylon. Today the 402 in it’s Century version is the choice of Tandem pilots who like to keep a low wing load to still enjoy a relatively agile
and dynamic Tandem canopy. MSW 225 kg.

Twin Century 372

The most widely sold size of all Twin Tandem canopies, the 372 impresses through it’s dependable openings and low toggle pressure. MSW : 215 kg.

Twin Century 340

Our most dynamic Tandem Canopy.The Twin 340 is ideal for lightweight Tandem Pilots, seeking a canopy which is agil, easy to handle with a light toggle pressure and a low overall system weight. With only 16.5 kg for the whole rig, the Twin 340 is a dream in terms of comfort and overall performance. MSW 205 kg.

Background
The original Icarus Canopies (now JYRO) Tandem canopy was the first zero porosity tandem released to the market. Today’s JYRO Tandem stems from those strong roots: proven construction, now with newer, better fabrics, an elliptical shape and options found nowhere else in the industry.

Materials
With tough ZP construction the JYRO Tandem will retain it’s as-new performance for thousands of jumps. Your tandem instructors won’t be avoiding older rigs any more – but the packers might be avoiding the new ones at first!

The JYRO Tandem has passed the test of time. It’s strong, tough, loved by tandem instructors and has a low malfunction rate. She’s a beauty.

This is the tandem canopy for dropzones who demand only the best for their passengers, instructors, and themselves.

What can you expect when you fly your JYRO Tandem for the first time?
Smooth familiarity, responsive flight, and a quiet comfortability knowing you’ve done all this before. The JYRO Tandem is reminiscent of your everyday large sports canopy – you’ll feel at home from the moment you pitch until the moment your passenger slides gently onto the landing area.

Openings
The openings are soft, consistent, comfortable and take 500-700ft. There is a variable lip over the nose there is no flag or hole in the slider – the slider is flat. There are no brake settings, which makes for easy packing with no downside. She opens centre cell first with the ends collapsed and the remaining cells inflate slowly. Off-heading openings do happen but she doesn’t dive away; even testing the wing Tandem Terminal (drogueless) she gave nothing but sweet smooth openings.

Inputs
The control inputs, whether dual or single toggles, provide a huge amount of performance and range. She reacts with speed and precision and goes exactly where you put her. There is just the right amount of feedback, so your passenger stays comfortable, and her agility means that you can still have some fun on your way down!

Using the dual set up you will notice refreshingly light toggle pressure when using only the steering toggles, giving you fast, responsive manoeuvrability with a little less effort. Come time to pick up the flare toggles you will notice the added power giving you confident, consistent landings. With the single toggle setup, it’s comparable to that of a large sports wing – a quick response and all the power ready to go at the pull of a toggle.

When landing time comes, the single setup offers everything required for the same confident and consistent landings.

Stall Point
The JYRO Tandem has an extremely deep stall point bordering on almost impossible to find! You can be comfortable knowing she will maintain safe flight while sitting in deep brakes. This makes stacking for landing a hassle and worry free job.

Performance
Powerful responsive toggles for a ton of flare power, an extremely efficient glide for getting back from long spots and a very stable platform for handling rough turbulence.

The Dive
She offers a comfortable dive that helps generate added speed and power, translating to a powerful flare.

Recovery
With a generous yet safe recovery, the JYRO Tandem allows for a more natural feeling, similar to what you would feel on a larger sport canopy. These familiar characteristics that the pilot is used to make for a safer and more predictable wing.

Landings
A fully elliptical planform means landings are a dream. Landings on the 365 size and above are more gentle than any tandem canopies we’ve tried. The 6 & 2 option is manoeuvrable enough to build up a lot of speed for a good surf if that’s what you’re into. Nil winds with heavy loads will still have some minimal forward speed, and the light toggle pressure makes flaring and controlling the flare suuuuper easy.
