5.1 This test method provides a standard for comparison of rotating type anemometers, specifically cup anemometers and propeller anemometers, of different types. Specifications by regulatory agencies (4-7) and industrial societies have specified performance values. This standard provides an unambiguous method for measuring starting threshold, distance constant, transfer function, and off-axis response.1.1 This test method covers the determination of the starting threshold, distance constant, transfer function, and off-axis response of a cup anemometer or propeller anemometer from direct measurement in a wind tunnel.1.2 This test method provides for a measurement of cup anemometer or propeller anemometer performance in the environment of wind tunnel air flow. Transference of values determined by these methods to atmospheric flow must be done with an understanding that there is a difference between the two flow systems.1.3 The values stated in SI units are to be regarded as standard. The values given in parentheses after SI units are provided for information only and are not considered 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.

This specification covers airworthiness requirements for the installation and integration of propeller systems, and is applicable to aeroplanes as defined in F44 terminology standard. The applicant for a design approval must seek the individual guidance to their respective civil aviation authority (CAA) body concerning the use of this specification as part of a certification plan.The requirements prescribed in this specification cover: propeller installation aspects (general propeller, feathering propellers, variable-pitch propellers, pusher propeller installation, propeller clearance), structural aspects (propeller vibration and fatigue), propeller control limitations (propeller speed and pitch limits, propeller reversing systems), and associated propeller systems (oil system-propeller feathering systems, turbopropeller-drag limiting systems).1.1 This specification addresses the airworthiness requirements for the installation and integration of propeller systems.1.2 This specification is applicable to aeroplanes as defined in F44 terminology standard.1.3 The applicant for a design approval must seek the individual guidance to their respective CAA body concerning the use of this standard as part of a certification plan. For information on which CAA regulatory bodies have accepted this standard (in whole or in part) as a means of compliance to their Small Aircraft Airworthiness regulations (Hereinafter referred to as “the Rules”), refer to ASTM F44 webpage (www.ASTM.org/COMITTEE/F44.htm) which includes CAA website links. Annex A1 maps the Means of Compliance described in this specification to EASA CS-23, amendment 5, or later, and FAA 14 CFR Part 23, amendment 64, or later.1.4 Units—The values stated are SI units followed by Imperial units in square brackets. The values stated in each system are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined.1.5 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.1.6 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.
