Full title and description

ISO 10046:1996 — Aircraft — Methodology of calculating cargo compartment volumes. This international standard specifies a consistent methodology for determining the internal volumes of aircraft cargo compartments (main deck and lower deck) and for defining required clearances that affect unit load device (ULD) contours and volumes.

Abstract

Covers the methodology for calculating the internal volumes of both main-deck and lower-deck aircraft cargo compartments. It specifies the minimum required clearance between the compartment envelope and unit load devices (ULDs) so as to define the maximum ULD external contour and provides the methodology to define ULD internal volumes.

Scope

Defines a standard calculation methodology to determine internal cargo compartment volumes for transport-category aircraft, addressing both main-deck and lower-deck compartments. The scope includes specification of minimum clearances between compartment envelopes and unit load devices (ULDs) to enable consistent determination of maximum external ULD contours and internal ULD volumes used in aircraft design, loading and logistics planning. The standard is intended for use where consistent compartment and ULD volume definitions are required for design, certification input, cargo stowage planning and interoperability of ULDs.

Key topics and requirements

• Methodology for calculating internal volumes of main-deck and lower-deck cargo compartments.
• Definition of minimum clearances between compartment envelope and unit load devices (ULDs).
• Procedure to derive maximum ULD external contour (envelope) from compartment geometry.
• Methodology to define ULD internal volumes consistent with external contour and clearance rules.
• Standardized terms and calculation rules to improve interchangeability between aircraft manufacturers, ULD suppliers and operators.

These topics follow the abstract and technical scope published in the ISO record for ISO 10046:1996.

Typical use and users

Primary users include aircraft designers and manufacturers, cargo compartment and interior systems engineers, ULD (container/pallet) designers and manufacturers, airline cargo planners, ground-handling organizations, regulatory authorities and certification bodies, and organizations responsible for aircraft loading and weight-and-balance documentation. Typical uses are design validation, ULD sizing and contour definition, cargo-loading planning, and providing consistent data for aircraft type-specific weight-and-balance and cargo stowage manuals. (Context on ULD operational relevance and industry use is commonly referenced in IATA and industry guidance.)

Related standards

Standards and guidance commonly associated with ISO 10046:1996 include industry and regulatory material governing ULD design, testing and operation (for example IATA’s ULD Regulations and related industry manuals), airworthiness and ULD certification requirements (FAA/EASA technical standards/orders for ULDs), and newer ISO work on ULD performance and testing (for example ISO documents addressing ULD performance and test parameters). These documents are used together with ISO 10046 when defining allowable ULD contours, certification inputs and operational procedures.

FAQ

Q: What is this standard?

A: ISO 10046:1996 is an ISO international standard titled "Aircraft — Methodology of calculating cargo compartment volumes" that defines methods for determining internal cargo compartment volumes and associated clearances used to establish ULD contours and volumes.

Q: What does it cover?

A: It covers calculation procedures for main-deck and lower-deck compartment internal volumes, the minimum clearance relationships between compartments and ULDs, and the methodology for deriving maximum external ULD contours and ULD internal volumes to ensure consistent, repeatable volume definitions.

Q: Who typically uses it?

A: Aircraft manufacturers and designers, ULD designers and manufacturers, airlines and cargo planners, ground-handling organizations, and aviation authorities/certification bodies—any stakeholder that needs consistent, standardized compartment and ULD volume definitions.

Q: Is it current or superseded?

A: As recorded by ISO, ISO 10046:1996 was last reviewed and confirmed in 2024 and remains the current published version (Edition 1, 1996). Users should consult ISO or their national standards body for the official publication and any amendments.

Q: Is it part of a series?

A: ISO 10046:1996 was developed under ISO/TC 20/SC 9 (aircraft and space vehicle engineering — aircraft equipment and systems) and is commonly used in conjunction with other aircraft and ULD-related standards and industry regulations (for example IATA ULD Regulations and airworthiness/certification technical orders). It is not a multi‑part ISO series itself but sits within the body of ISO and industry documents addressing cargo, ULDs and aircraft equipment.

Q: What are the key keywords?

A: Aircraft cargo compartment, cargo volume, ULD, unit load device, compartment clearance, ULD contour, cargo stowage, ISO 10046, aircraft design, cargo planning.
