Full Description

The Aerospace Standard (AS) presents a system of graphic symbols intended primarily for usage in hydraulic an dpneumatic system schematic diagrams for all types of aircraft. It is also considered suitable for marine vehicles and other applications and for ancillary documents where schematics are required.
