HELICOPTERS (Air-Cushion Vehicles B60V)
CPC - B64C - 2020.02 B64C AEROPLANES; HELICOPTERS (air-cushion vehicles B60V) Special rules of classification The use of the available Indexing Codes under B64C 1/00- B64C 2230/00 is mandatory for classifying additional information. B64C 1/00 Fuselages; Constructional features common to fuselages, wings, stabilising surfaces and the like (aerodynamical features common to fuselages, wings, stabilising surfaces, and the like B64C 23/00; flight-deck installations B64D) Definition statement This place covers: • Overall fuselage shapes and concepts (only documents relating thereto are attributed the symbol B64C 1/00, when the emphasis is on aerodynamic aspects the symbol B64C 1/0009 is attributed). • Structural features (including frames, stringers, longerons, bulkheads, skin panels and interior liners). • Windows and doors (including hatch covers, access panels, drain masts, canopies and windscreens). • Fuselage structures adapted for mounting power plants, floors, integral loading means (such as steps). • Attachment of wing or tail units or stabilising surfaces to the fuselage; • Relatively movable fuselage parts (for improving pilot's view or for reducing size for storage). • Severable/jettisonable parts for facilitating emergency escape. • Inflatable fuselage components. • Fuselage adaptations for receiving aerials or radomes. • Passive cooling of fuselage structures and sound/heat insulation (including isolation mats, and clips for mounting such mats and components such as pipes or cables). References Limiting references This place does not cover: Structural features and concepts are attributed the relevant symbol(s) in B64C 1/06 - B64C 1/12 Aerodynamical features common to fuselages, wings, stabilising B64C 23/00 surfaces, and the like Flight-deck installations B64D Special rules of classification Structures and components for helicopters falling within this main group and/or appended subgroups are additionally attributed the symbol B64C 27/04.
