SIGMA TANDEM SYSTEM OWNER’S MANUAL<br />

After you have performed the above described emergency drills, have a partner act as a student<br />

and suspend yourselves in a hanging Tandem harness. Repeat the emergency procedures enough<br />

times to ensure that the movements become natural and instinctive. Take note of the different<br />

positions of the handles while in a suspended mode. (Statistics have shown that the Tandem<br />

Vector’s most common malfunction mode is a typical main canopy malfunction where the control<br />

lines are entangled with the rear riser lines with a possible slider hang up. This problem can be<br />

avoided by proper packing, maintaining good line tension throughout, and the use of proper stow<br />

bands to prevent line dump.)<br />

DO NOT TAKE THIS DRILL LIGHTLY. If you should ever experience a malfunction, this practice<br />

will give you the skills needed to deal with the problem effectively.<br />

By ordering an extra pair of Tandem main risers and toggles, one can easily setup a training<br />

harness with an actual Tandem system. Remove the entire main canopy assembly (from risers to<br />

drogue) and suspend the system using the extra pair of risers. To prevent excessive wear of the<br />

Tandem system, order or produce your own training harness to be used exclusively for training<br />

and recurrency work.<br />

CANOPY BRAKES AND STEERING SYSTEM<br />

Deployment brake release<br />

1) Grasp main steering toggles and pull outwards away from the riser, unsnapping the toggles.<br />

Use the student toggle position during brake release.<br />

2) Pull toggles down to release the brakes. Do not pull on the small black flare toggles - leave<br />

them attached to the risers.<br />

Double brake system for the Tandem Vector canopy<br />

The Relative Workshop Double Brake System is an innovation in the steering line set up on<br />

Tandem systems that provides reduced toggle pressure and faster turns during normal flight while<br />

at the same time producing extra stopping power in low wind conditions.<br />

As shown in Illustration #2/1-5 on page #10, there are seven steering lines (EZ425, 384 &<br />

Sigma 370, 395, 340 models) on each side of the canopy. Unlike most canopies, the lines are a<br />

ttached at the full cell junctions, rather than at the half cell point. When so much of the canopy tail<br />

is pulled down for landing, it makes for an exceptional flare, and therefore, a softer landing. For<br />

normal flight and turns, the inside lines are not needed. In fact, they are a hindrance during turns,<br />

increasing toggle pressure, and slowing turn rate. To deal with this situation, the double brake<br />

system has been set up so that the inside “extra” lines are used only during the flare for landing.<br />

During main canopy opening, reach up and grab the right and left gold, lower student toggles<br />

only (do not touch the black flaring toggle). Peel the toggles in a rearward direction for easy toggle<br />

and brake release. If toggles are pulled straight down, their release will be difficult or impossible<br />

due to the amount of velcro and the additional snap holding them in place, and you may cause<br />

damage to both components.<br />

For normal flight, from opening altitude down to approximately 500 feet, use only the gold toggles.<br />

Prior to landing, reach up and take the black flaring toggles by inserting four fingers and closing<br />

your grip. Now you are ready to land. The black toggles lay flat and may be difficult to access<br />
