Introduction 1.1 Scope This owner’s manual constitutes the manufacturer’s instructions for the operation, packing, and maintenance of the 311 Wedge Emergency Parachute System. 1.2 FAA Approval Originally certified in 1973 under TSO C-23b, standard category, the Para-Cushion parachute as- semblies were upgraded in 1992 and are now FAA approved under TSO C-23c, category B (in accor- dance with AS 8015A and FAR 21, Subpart O). -
Page 3: Model Description
This manual covers Para-Cushion packed with the following emergency canopies man- ufactured by Strong Enterprises: the 26-foot Standard Lo-Po, the 26 foot Military Lo-Po and the 26 foot Mid-Lite. These three canopies utilize low porosity (Lo-Po) cloth which allows less air flow, and therefore a slower, more stable rate of descent than conventional parachute cloth. -
