NOTE: These specifications are intended only as a guideline for determining whether a
given glider is a certifIed model and whether it is in the certified configuration. Be
aware, however, that no set of specifications, however detailed, can guarantee the

as was certified, or has those performance, stability, and structural characteristics
required by the certification standards. An owner’s manual is required to be delivered
