ASTM F3011-21 PDF

ABSTRACT This specification establishes functional operation and minimum performance requirements for simple systems that provide angle-of-attack information to a pilot, aircraft, or other systems. Functional requirements cover basic operation, stall indication, startup of electronically driven systems, accessibility of controls, and software while environmental requirements include icing, deicing fluids, emissions of RF energy, electrical power input, and power input abnormal surge voltage. SCOPE 1.1 This performance specification covers simple systems that provide angle-of-attack information to a pilot, aircraft, or other systems. Note 1: More complex AoA systems can be addressed in annexes in the future. 1.2 In this performance specification, functional operation and minimum performance requirements for an angle-of-attack system are established. 1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.4 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. 1.5 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.
