Overview
ISO 6702-2:1991 specifies the design, performance and interface characteristics for on-board weight and balance systems used in civil transport aircraft. This Part 2 of ISO 6702 adopts ARINC 737:1985 and its Supplement 1 (1988) as a de facto international standard and supplements the general provisions given in ISO 6702‑1 (Part 1). The standard was developed by ISO/TC 20 (Aeronautics and space), sub‑committee SC 9 (Ground handling and ground support equipment).
Key topics and technical requirements
- Design characteristics: Requirements for the architecture and hardware/firmware considerations of on-board weight and balance systems to ensure reliable aircraft mass and center-of-gravity data.
- Performance characteristics: Performance criteria for accuracy, update rates, fault tolerance and operational reliability consistent with transport aircraft needs (applies to systems meeting Class I or Class II in ISO 6702‑1).
- Interface characteristics: Standardized data interfaces and protocols to integrate weight and balance systems with aircraft avionics, flight management systems and cockpit displays.
- Adoption of ARINC 737: The detailed prescriptions are given in ARINC 737:1985 and its 1988 Supplement 1, which ISO 6702-2 adopts; ISO/TC 20 will be consulted on any revisions to ARINC 737.
- Scope limitations: The document covers on‑board systems for civil transport aircraft and refers users to ARINC publication for full technical text.
Applications and users
ISO 6702-2 is intended for:
- Aircraft manufacturers (OEMs) designing or integrating on‑board weight and balance systems.
- Avionics and systems suppliers building sensors, processors and interface units for mass and center‑of‑gravity determination.
- Airlines and operators seeking interoperable, standardized on‑board weight and balance functionality to support load planning and flight performance.
- Certification authorities and regulatory bodies that assess compliance of on‑board weight and balance equipment.
- Maintenance organisations and systems integrators implementing or upgrading avionics interfaces and ensuring consistent performance.
Practical benefits include improved flight safety, repeatable weight/C of G calculations, easier avionics integration, and clearer criteria for certification and procurement.

Foreword
ISO (the International Organization for Standardization) is a worldwide
federation of national Standards bodies (ISO member bodies). The work
of preparing International Standards is normally carried out through ISO
technical committees. Esch member body interested in a subject for
which a technical committee has been established has the right to be
represented on that committee. International organizations, govern-
mental and non-governmental, in liaison with ISO, also take part in the
work. ISO collaborates closely with the International Electrotechnical
Commission (IEC) on all matters of electrotechnical standardization.
Draft International Standards adopted by the technical committees are
circulated to the member bodies for voting. Publication as an Interna-
tional Standard requires approval by at least 75 % of the member bodies
casting a vote.
International Standard ISO 67022 was prepared by Technical Committee
ISO/TC 20, Aircraft and space vehicles, Sub-Committee SC 9, Air cargo
and ground equipment.

Avant-propos
L’ISO (Organisation internationale de normalisation) est une fédération
mondiale d’organismes nationaux de normalisation (comités membres
de I’ISO). L’élaboration des Normes internationales est en général
confiée aux comités techniques de I’ISO. Chaque comité membre inté-
ressé par une étude a le droit de faire partie du comité technique créé
à cet effet. Les organisations internationales, gouvernementales et non
gouvernementales, en liaison avec I’ISO participent également aux tra-
vaux. L’ISO collabore étroitement avec la Commission électrotechnique
internationale (CEI) en ce qui concerne la normalisation électrotech-
nique.
Les projets de Normes internationales adoptés par les comités techni-
ques sont soumis aux comités membres pour vote. Leur publication
comme Normes internationales requiert l’approbation de 75 % au moins
des comités membres votants.
La Norme int,ernationaIe ISO 6702-2 a été élaborée par le comité tech-
nique ISO/TC 20, Aéronautique et espace, sous-comité SC 9, Char-
gement et équipement au sol.
