ASTM F3061/F3061M-25 PDF

Full title and description

ASTM F3061/F3061M-25 — Standard Specification for Systems and Equipment in Aircraft. This document specifies systems- and equipment-related design, installation, and airworthiness guidance intended primarily for normal-category general aviation aeroplanes (Level 1–4). Topics include electrical and environmental systems, flight controls, recording systems, hazard mitigation, hydraulics and pneumatics, lighting, oxygen, lightning/HIRF protection, instrumentation, and other mechanical systems and equipment.

Abstract

This standard consolidates consensus-based technical requirements and guidance for aircraft systems and equipment to support design approval and means-of-compliance submissions. It is intended as a practical specification for designers, manufacturers, and applicants seeking an acceptable means of compliance for normal-category aeroplane systems and equipment; users should coordinate with their applicable civil aviation authority when using the standard as a means of compliance.

Scope

The specification covers the systems and equipment aspects of airworthiness and design for aircraft, developed with a focus on Level 1–4 normal-category aeroplanes but with content that may be applicable more broadly where substantiated by the applicant. It addresses basic information and requirements for electrical systems, environmental systems, manual and automatic flight controls, flight data and voice recording, hazard mitigation and engine/powerplant installation interfaces, hydraulic and pneumatic systems, instrumentation and crew interfaces, exterior lighting, oxygen systems, lightning protection and HIRF, mechanical systems and related equipment. Use as a Means of Compliance requires coordination with the relevant oversight authority.

Key topics and requirements

• Design and installation guidance for aircraft electrical and environmental systems.
• Manual and automatic flight control system considerations, including interfaces and fail-safety principles.
• Requirements for flight data and voice recording systems where applicable.
• Hazard mitigation measures for powerplant installations and other critical systems.
• Specifications for hydraulic, pneumatic, oxygen, and mechanical systems and equipment.
• Exterior lighting, lightning protection, and high-intensity radiated field (HIRF) protection guidance.
• Unit system usage (SI and English engineering units) and guidance on independent unit-system application.

Typical use and users

Typical users include aircraft designers, systems engineers, manufacturers of aircraft systems and equipment, conformity/airworthiness applicants, certification specialists, and civil aviation authorities reviewing means-of-compliance material. The standard is used to inform design specifications, installation practices, compliance demonstrations, and certification packages for normal-category general aviation aeroplanes.

Related standards

F3061/F3061M-25 is part of the suite of ASTM F44 standards used for means-of-compliance to certain airworthiness rules. Closely related and frequently referenced documents include earlier editions of F3061/F3061M (for example 23/23A/22b/16B), and other F44 standards such as F3062/F3062M (powerplant installation), F3063/F3063M (fuel and energy storage/delivery), F3064/F3064M (powerplant control and indication), F3232/F3232M (flight controls), F3233/F3233M (flight/navigation instrumentation), F3114 (structures), and F3117 (crew interface). Regulatory lists of accepted Means of Compliance reference many of these standards.
