SCOPE This Aerospace Standard (AS) presents a system of graphic symbols intended primarily for usage in hydraulic and pneumatic system schematic diagrams for all
39、 types of aircraft. It is also considered suitable for marine vehicles and other applications and for ancillary documents where schematics are required. Individual graphic symbols shown herein are also considered suitable for use in conjunction with other types of symbols. This AS is intended to pro
40、mote industry-wide acceptance and understanding of uniform standards and employs, where possible, symbols which are internationally recognized. 2.

GENERAL SYMBOL RULES 3.1 Description and Method Elementary forms of symbols are: x Circles x Squares x Rect
46、angles x Triangles x Arcs x Arrows x Lines x Dots x Crosses Some symbols (such as selector valves) appear as logic configurations, with no resemblance to components; others (such as actuators and accumulators) are shape-oriented for symbolic representation. In all cases, the component function is em
47、phasized by the symbol. Symbols show connections, flow paths, functions and the methods of operation of the components that they represent. They can indicate the condition occurring during transition from one flow path to another. They may be rotated or reversed without altering their meaning except
48、 in the case of reservoirs or similar as specified. They distinguish between modular and non-modular components, liquid and gaseous fluid media and fluid line functions. Symbols do not indicate construction, location or identification of ports as on the component, direction of shifting spools or positions of actuators on actual components. They do not indicate values such as pressure, flow rate or other component settings and do not indicate actual liquid levels or system conditions by symbolic instrument needle positions. E
