FAI Class Definitions for Hang Gliders

• Class 1: hang gliders having a rigid primary structure with pilot weight-shift as the primary method of control, and which are able to demonstrate consistent ability to safely take off and land in nil-wind conditions (see Note).
• Class 2: hang gliders having a rigid primary structure with movable aerodynamic surfaces as the primary method of control in at least two axes, and which are able to demonstrate consistent ability to safely take off and land in nil-wind conditions (see Note).
• Class 3: hang gliders having no rigid primary structure (paragliders), and which are able to demonstrate consistent ability to safely take off and land in nil-wind conditions (see Note).
• Class 4: hang gliders that are unable to demonstrate consistent ability to safely launch and land in nil-wind conditions.

Note: for the purposes of demonstration, "nil wind" shall mean a headwind of less than 1 m/s (3.6 km/h; 2.2 mph).
