Standard Practice for UAS Registration and Marking (Excluding Small Unmanned Aircraft Systems)

SIGNIFICANCE AND USE
4.1 Aircraft flying in national airspace are required by the ICAO Chicago Convention and national regulatory rules to have visible markings to determine nationality and registration. UAS shall comply with these rules, although small UAS will have unique rules or exemptions from existing rules due to their small size. This standard is designed to allow UAS to comply with these marking requirements in Annex 7 to the Convention on International Civil Aviation as amended by state regulatory rules.  
4.2 Many ICAO states are assigning UAS to different classes and categories to define the rules UAS must operate under. The ICAO Annex 7 Standards and Recommended Practices (SARPS) apply to UAS Aircraft with the exception of small UAS. The classification of what constitutes a small UAS (sUAS) has been left to ICAO states and the rules under which sUAS operate are dictated by each state.  
4.3 This practice follows ICAO Annex 7 SARPS except in areas where the unique aspects of UAS may not allow compliance. In these cases, this document will address the issue and recommend the need for an alternate compliance method.
SCOPE
1.1 This practice prescribes guidelines for the display of marks to indicate appropriate UAS registration and ownership for all Unmanned Aircraft Systems (UAS) except those categorized as small UAS (sUAS) by regulatory authorities. The FAA is developing a Special Federal Aviation Regulation (SFAR) to define the term small UAS and provide regulations for these aircraft.  
1.2 This practice will allow determination of nationality in cases where UAS may cross international boundaries.  
1.3 This practice does not apply to sUAS. The International Civil Aviation Organization (ICAO) has left the designation of sUAS to each state and the states will develop rules and regulations for sUAS.  
1.4 This practice does not apply to model aircraft.  
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.

Overview

ASTM F2851-10(2018): Standard Practice for UAS Registration and Marking (Excluding Small Unmanned Aircraft Systems) is an internationally recognized guideline developed by ASTM International. This standard addresses the procedures and requirements for the registration and marking of Unmanned Aircraft Systems (UAS) operating in national and international airspace, excluding small UAS (sUAS) as designated by national regulatory authorities. The practice ensures that UAS comply with regulatory rules established under the International Civil Aviation Organization (ICAO) for identification and nationality markings, contributing to global aviation safety and interoperability.

Key Topics

  • Scope and Applicability:

    • Applies to all UAS except those classified as sUAS or model aircraft by regulatory authorities.
    • Focuses on compliance with ICAO Annex 7 Standards and Recommended Practices (SARPS) for aircraft registration and marking.
    • Excludes small UAS, which are subject to country-specific regulations.
  • Registration and Marking Requirements:

    • Prescribes visible markings indicating nationality and registration, essential for aircraft operating across international boundaries.
    • Stipulates the use of identification plates made of fireproof materials, affixed in accessible and prominent positions on the UAS.
    • Requires that registration marks be painted or affixed permanently, unornamented, contrasting in color, and legible.
  • National vs International Regulations:

    • Countries may have exceptions to ICAO Annex 7 and assign their own categories and rules for UAS.
    • References U.S. regulations (such as 14 CFR 45 and 14 CFR 47) relevant for registration and marking.
  • Exemptions and Special Considerations:

    • Recognizes situations where UAS design prevents compliance with conventional marking requirements and recommends alternate methods.
    • Manufacturers may seek exemptions from their regulatory authorities when full compliance is not feasible due to specific UAS characteristics.

Applications

ASTM F2851-10(2018) is practically valuable for:

  • Manufacturers and Operators:

    • Ensures compliance with national and international laws for UAS operation and cross-border flights.
    • Provides a clear framework for UAS marking and registration, enhancing identification and traceability.
  • Civil Aviation Authorities:

    • Offers standardized guidelines for enforcement and regulation of UAS registration and nationality markings, excluding sUAS.
    • Facilitates harmonization of UAS operational rules by providing alignment with ICAO Annex 7 SARPS.
  • Regulatory Compliance:

    • Supports legal operation of UAS in regulated airspace, reducing the risk of non-compliance penalties.
    • Enables authorities to efficiently enforce airworthiness, ownership, and operational status.
  • International Operations:

    • Streamlines the process for UAS operating across multiple countries by adhering to recognized international marking standards.

Related Standards

For further guidance and regulatory context, the following standards and documents are referenced:

  • Annex 7 to the Convention on International Civil Aviation (ICAO):

    • Provides the basis for nationality and registration marks on civil aviation aircraft, including UAS.
  • 14 CFR 45 (U.S. Identification and Registration Marking):

    • U.S. regulations for the display of aircraft nationality and registration marks.
  • 14 CFR 47 (U.S. Aircraft Registration):

    • Procedures for aircraft registration with the Federal Aviation Administration.
  • ASTM F2395 (Withdrawn):

    • Terminology for unmanned aircraft systems, providing a foundational vocabulary.

For UAS that fall under the small UAS (sUAS) category, relevant regulations are developed by individual states and may differ substantially.
