container system), the pre-flight check must additionally include the correct attachment
of the riser!
For winch towing, the instructions of the harness, paraglider/hang glider and winch
manufacturer must be followed! When using a front container, it must be ensured that the
deployment of the rescue parachute is possible at all times.
Its S-shaped canopy trim provides a high righting moment, so that the DIAMONDcross
is in a stall for a short time imediately after opening. This reliably prevents a downplane
position of the reserve. The paraglider is quickly unloaded and dives down. This prevents
the danger of a scissor position between the rescue system and the paraglider, facilitates
the recovery of the main glider and even allows the unhooking of one riser with CHARLY
Pinlock or even conventional carabiners.
The sinking of the DIAMONDcross during stall corresponds to that of a conventional cross
canopy. The then beginning forward movement in the direction of the red marked corner
further reduces the sink rate significantly.
Since the S-shaped canopy trim additionally ensures high pendulum stability, also the
hang glider versions of the DIAMONDcross benefit from its advantages.
Steerability is an optional feature of the paraglider ST versions of the DIAMONDcross. If it
is not used after deployment, e.g. due to low altitude, the landing will be the same as with
a conventional cross canopy.
If required, the paraglider Basic versions of the DIAMONDcross can be converted to be
steerable by the manufacturer at a later date.
Forward motion
Significant forward speed only occurs after the paraglider has been pulled in or separated.
The trim of the DIAMONDcross canopy results in a flying speed of up to 15 km/h or a glide
ratio of about 1:1,5. This gives the pilot the possibility, e.g. at 500 meters above ground,
to target a landing area of about 1,7 km² for landing. At lower deployment altitudes, it is at
least still possible to avoid obstacles; at higher altitudes, it is even possible to steer from
the ridge down into the valley or towards a safe landing area.
The horizontal drift of the DIAMONDcross also helps to reduce the risk of injury, because
the deceleration path to reduce the impact speed is shortest in the case of a vertical impact
on a flat surface, while lower forces act on the body in the case of an angular impact. In
addition, the human body is not equally resilient in all axes. The most sensitive axis is the
one in the direction of the spine, which has to cushion an impact on the buttocks.
Twists with steerable reserves
Since after deployment, the inner container package is thrown more or less uncontrolled
into the open airspace, and rotations of the container before the canopy unfolds cannot
be completely avoided, a steerable reserve sometimes opens twisted. Steerable rescue
systems have the characteristic that the main glider will always be turned away from the
flight direction due to the air resistance. Even if the main glider still has open surface, a
