Air Cargo Unit Load Devices - Performance Requirements and Test Parameters
|Publication Date:||1 September 2020|
This SAE Aerospace Standard (AS) defines the minimum performance requirements and test parameters for air cargo unit load devices requiring approval of airworthiness for installation in an approved aircraft cargo compartment and restraint system that complies with the cargo restraint requirements of Title 14 CFR Part 25, except for the 9.0-g forward ultimate inertia force of § 25.561 (b)(3)(ii).
The purpose of this Aerospace Standard is to establish the minimum requirements for airworthiness approval of air cargo pallets, nets, and containers, generally designated as air cargo unit load devices.
Other aspects that do not directly pertain to airworthiness approval and testing are defined in other Aerospace Standards and Aerospace Recommended Practices, e.g.,
• ULD design specifications
• ULD in service damage limits
• ULD restraint malfunction limitations
• ULD load distribution models
• ULD maximum allowable contours
• ULD CG location control means
• ULD pressure equalization methods
• ULD utilization guidelines
Field of Application
This Aerospace Standard applies to all airworthiness approved air cargo unit load devices intended for carriage on board civil transport category airplanes type certificated under Federal Aviation Regulations Title 14 CFR Part 25.
It exclusively applies to unit load devices airworthiness approval and testing parameters. It does not apply to either aircraft design or aircraft operating requirements, which are provided by the approved weight and balance manual for each aircraft type.
Air cargo unit load devices qualified prior to publication of this Aerospace Standard were TSO approved in accordance with the requirements of National Aerospace Standard NAS3610 (latest published revision 10, 1st November 1990), internationally recognized under ISO 8097 (latest published revision: 4th edition, 2000).
Air cargo unit load devices the size or type of which is not covered in this Aerospace Standard are to be airworthiness approved in accordance with the requirements of NAS3610 revision 10, if their size or type is contained therein, or other equivalent criteria, if not.
NOTE: The requirements for cargo covers are not defined in this Aerospace Standard, except insofar as net restraint is incorporated therein.

Type 2 nets, pallets, and containers (ULDs) described in this Aerospace Standard are intended for use only in an approved aircraft cargo compartment and restraint system where compliance with the 9.0 g forward ultimate inertia force of Title 14 CFR Part 25 § 25.561 (b)(3)(ii) is achieved either by supplementary installation of a barrier net or bulkhead, or by specified approved placement of the ULD in the aircraft.
NOTE: Type 1 ULDs are not shown in this Aerospace Standard. Refer to National Aerospace Standard NAS3610 Revision 10.View Less
