Terminology and Definitions for Aerospace Fluid Power, Actuation and Control Technologies
This SAE Aerospace Recommended Practice (ARP) comprises the technical terms and nomenclature, together with their definitions and abbreviations that are used in aerospace Fluid Power Actuation and Control Systems.
NOTE: When a term is applicable to more than one branch or segment of the technology it may have different meanings and definitions in each. Where this occurs the multiple listings with appropriate designations will be shown under the same primary term.
ARP4386 was reviewed for specific terms relating to the new type of control actuators, called Electrohydrostatic Actuation Systems (EHAS) and Integrated Actuation Packages (IAP). This revision incorporates the changes required for the EHAS and IAP, either by amending existing terms or by adding new ones.
