Classification
The Fédération Aéronautique Internationale Gliding Commission's Sporting Code defines the classes for gliding competitions and records. One of the classes is the ultralight glider. These are defined as gliders with a take-off mass not exceeding 220 kg (486 lb). Examples of these are the Apis and Silent 2. Microlift gliders are a sub-type of the ultralight class, further defined by a wing loading that does not exceed 18 kg/m² (3.69 lb/ft2).These definitions were adopted for inclusion in the Sporting Code, Section 3, Gliding, effective on October 1st, 2004.
World records for the ultralight class have been recognized by the FAI but there are no World Championships for these types at present. For world records microlift gliders are classed with the other ultralight gliders and/or hang gliders.
The FAI has produced a loaded weight versus wing loading diagram defining the different domains for glider classes.
