Chief designer Ernst Strobl counts on the efficiency of simplification at the CROSSROCK. That does not only lead to a weight reduction but also gives the wing its outstanding characteristics. Based on the concept for success
of Blacklight 2 several modifications for the CROSSROCK were made to maintain the form fidelity at long durability. The sharknose provides more stability at higher speeds. The 3D-shaping gives the leading edge a dynamic
tension and elevates - in combination with the Precision Profile Nose (PPN) - the profile fidelity in the nose area. Pre-tensioning of the wing and the ballooning help to provide the perfect flow around the profile through
elaborate calculations. The High Pressure Crossport Design (HPCD) optimizes the lateral aeration of the crossports and provides a balanced internal pressure of the wing. The line-set-up with three main lines is very straight-forward. Here the newest generation of PPSLS lines are being used, which ensure extremely high loads with minimal diameter.
