1.1 This guide applies to any automated system that uses data from an aircraft to create an Aircraft Braking Action Report (ABAR) (see Terminology E3188). The system may be installed on an aircraft or operated remotely. This standard is intended to ensure that all ABARs created by automated systems meet a minimum level of quality and represent a standardized set of assumptions. This standard does not provide any guidance or means for the dissemination of an ABAR or related information.
1.1.1 Aircraft systems producing ABARs or ABAR-related flight crew alerts are covered by the appropriate regulatory guidance for aircraft certification.
1.2 This standard utilizes the terms and methods relating to aircraft anti-skid systems as documented in FAA AC 25-32.
1.3 Units—The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.4 Risk Management—Aircraft braking action reports contain information that may be used to reference the operating limits of an aircraft. Section 6 details the safety analysis and specific guidelines for airborne and remotely operated systems.
1.5 Operational Use—This standard does not address operational considerations nor recommend policies regarding the use of an aircraft braking action report.
1.6 Mandating and Recommended Phrases—To enhance comprehension and clarity, required and recommended tasks are listed with the following nomenclature:
1.6.1 The term “shall” is used to indicate a provision is mandatory. Such requirements are sequentially listed as “REQXX.”
1.6.2 The term “should” is used to indicate that a provision is recommended as a good practice. Such recommendations are sequentially listed as “RECXX.”
1.7 This standard provides guidance for performing one or more specific functions. This document cannot replace education or experience and should be used in conjunction with professional judgment. Not all aspects of this standard may be applicable in all circumstances. This ASTM standard is not intended to represent or replace the standard of care by which the adequacy of a given professional service must be judged, nor should this document be applied without consideration of a project’s many unique aspects. The word “Standard” in the title means only that the document has been approved through the ASTM consensus process.
1.8 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.9 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
