ASTM F3341/F3341M-23 PDF

Overview

ASTM F3341/F3341M-23: Standard Terminology for Unmanned Aircraft Systems provides industry-wide definitions for terms and concepts related to unmanned aircraft systems (UAS), including remotely piloted aircraft (RPA) and small unmanned aircraft systems (sUAS). Developed by ASTM International’s Committee F38, this terminology standard aims to ensure clear and consistent communication across all ASTM standards concerning UAS operations, manufacturing, safety, training, and regulatory compliance.

By harmonizing vocabulary, ASTM F3341/F3341M-23 supports manufacturers, operators, authorities, and stakeholders, helping to avoid misunderstandings and streamline documentation and compliance with international and regional requirements.

Key Topics

• Standardized Definitions: Establishes clear, authoritative meanings for UAS-specific terms, avoiding redundancy with related standards such as ASTM F3060 for aircraft terminology.
• Scope of Coverage: Focuses on terminology relevant to various UAS applications and technical areas, including airworthiness, software, control systems, and safety protocols.
• Global Harmonization: Facilitates international collaboration and regulatory alignment by adopting principles from globally recognized bodies such as the World Trade Organization’s TBT Committee.
• Unit Consistency: References NIST SP 330 for units of measurement, ensuring standards-compliant use of both SI and inch-pound units.
• Evolving Terminology: Allows the addition and updating of specialized vocabulary as UAS technology and practices advance.

Applications

This standard terminology is an essential reference for:

• Manufacturers and Developers: Ensures accurate, uniform terminology in design specifications, technical documentation, and product certifications.
• Operators and Training Providers: Supports creation of training materials, operational manuals, and instructional courses aligned with industry-recognized language.
• Regulatory Authorities: Assists in regulatory development, compliance audits, safety assessments, and certification processes for UAS and sUAS.
• Software and Systems Engineers: Clarifies definitions for concepts such as command and control, detect-and-avoid (DAA), autonomous systems, and software dependability.
• Academics and Researchers: Aids in the development of UAS research, ensuring consistency in terminology across studies and publications.
• Stakeholders and End Users: Improves understanding for customers, insurance assessors, risk managers, and legal experts involved in UAV operations.
