SAE ARP1070D

This document outlines the development process and makes recommendations for total antiskid/aircraft systems compatibility. These recommendations encompass all aircraft systems that may affect antiskid brake control. It focuses on recommended practices specific to antiskid and its integration with the aircraft as opposed to more generic practices recommended for all aircraft systems and components. It defers to the documents listed in Section 2, for generic aerospace best practices and requirements. The documents listed below are the major drivers in antiskid/aircraft integration: 1 ARP4754, Guidelines for Development of Civil Aircraft and Systems 2 ARP4761, Guidelines and Methods for Conducting the Safety Assessment Process on Civil Airborne Systems and Equipment 3 RTCA DO-178, Software Considerations in Airborne Systems and Equipment Certification 4 RTCA DO-254, Design Assurance Guidance for Airborne Electronic Hardware 5 RTCA DO-160, Environmental Conditions and Test Procedures for Airborne Equipment or MIL-STD-810, Environmental Engineering Considerations and Laboratory Tests 6 ARP490, Electrohydraulic Servovalves 7 ARP1383, Aerospace - Impulse Testing of Hydraulic Components In addition, it covers design and operational goals, general theory, and functions, which should be considered by the aircraft brake system engineer to attain the most effective skid control performance, as well as methods of determining and evaluating antiskid system performance. For definitions of terms used herein see Section 7. Significant changes in the design and testing of antiskid brake control systems for total aircraft compatibility have taken place since the publication of this document. For example, continuing changes to RTCA DO-160, Environmental Conditions and Test Procedures for Airborne Equipment, and MIL-STD-810, Environmental Engineering Considerations and Laboratory Tests, have caused this document to diverge from the standards being followed by the industry. A major goal of this revision is to focus this document on antiskid specific recommendations and refer to the appropriate documents and specifications for generic aerospace recommendations and practices. As a result, it has been completely reorganized. A great deal of material has been added and a great deal has been cut. Note that 1070D is a complete revision of the document. No change bars are used as virtually the whole document has changed.
