ASTM F3117/F3117M-23a

Standard Specification for Crew Interface in Aircraft

ABSTRACT
This specification covers international standards for the crew interface aspects of airworthiness and design for aircraft. The applicant for a design approval must seek the individual guidance of their respective civil aviation authority (CAA) body concerning the use of this specification as part of a certification plan.
The standards address pilot/occupant compartment; flight control systems controls; cockpit controls; motion and effect of cockpit controls; cockpit control knob shape; circuit breakers and fuses; master switch arrangement; flight control augmentation and auto flight system; primary flight information displays; primary flight guidance; and communication and audio systems. Also covered in this specification are pilot alerts; warning, caution, and advisory lights or indicators; continued airworthiness and maintenance; markings and placards; and airplane flight manual and approved manual material.
SCOPE
1.1 This specification covers international standards for the crew interface aspects of airworthiness and design for aircraft. “Crew” includes flight crew and maintenance crew. The material was developed through open consensus of international experts in general aviation. This information was created by focusing on Normal Category aeroplanes. The content may be more broadly applicable; it is the responsibility of the applicant to substantiate broader applicability as a specific means of compliance.  
1.2 An applicant intending to propose this information as Means of Compliance for a design approval must seek guidance from their respective oversight authority (for example, published guidance from applicable CAAs) concerning the acceptable use and application thereof. For information on which oversight authorities have accepted this specification (in whole or in part) as an acceptable Means of Compliance to their regulatory requirements (hereinafter “the Rules”), refer to ASTM Committee F44 web page (https://www.astm.org/COMMITTEE/F44.htm).  
1.3 Units—This document may present information in either SI units, English Engineering units, or both. 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.  
1.4 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.
