This specification covers pallet cargo tiedown nets, designated HCU-7/E, HCU-15/C, HCU-11/C and HCU-16/C.

Air cargo pallets and their cargo restraint nets constitute aircraft Unit Load Devices, defined by industry standards and airworthiness certified based on Technical Standard Order (TSO) C90c in accordance with the requirements of NAS 3610. This guarantees their design to be intrinsically safe for flight on board compatible aircraft types. However, actual flight safety also requires these certified pieces of equipment to be properly used: numerous occurrences have demonstrated a certified ULD can nevertheless jeopardize flight safety if loaded or restrained in an inadequate manner.

The requirements of this SAE Aerospace Recommended Practice (ARP) are applicable to ground handling and transport systems equipment which is designated to accommodate main deck unitized cargo in the form of intermodal containers and other compatible unitized load devices. Intermodality in the context of this document concerns primarily air and land modes but does not exclude the marine mode. Equipment with compatibility features for other than main deck cargo is likewise not excluded. It is not the intent of this document to specify equipment design but rather to ensure interface compatibility of the various elements which might make up a total ground handling and transport system developed within a number of different operational schemes. It is the intent of this document to specify minimum ULD handling and restraint features to ensure future interchange capability.

This SAE Aerospace Recommended Practice (ARP) establishes requirements for the function, characteristics, and installation of an aircraft On Board Weight and Balance System (OBWBS) for use on civil transport aircraft. This document is not intended to specify design methods, mechanisms, or material to accomplish the requirements set forth.

The dedicated aircraft addressed herein is to be an uncompromised all-freighter aircraft developed primarily for use in the civil transport industry. The requirements of this document are applicable but not limited to airborne equipment which is subject to the airworthiness directives of FAR Part 25 and which is designed to accommodate unitized cargo in the form of intermodal containers and other compatible unitized load devices. Intermodability in the context of this document encompasses the air-truck-rail-sea modes, and considers uncertificated as well as certificated unit load devices (ULDs). This document covers the fundamental prerequisites for the aircraft cargo compartment and the onboard cargo handling and restraining system. The cargo system and compartment considers primarily 96 in (2.44 m) wide, multiple bottom configuration ULDs. The cargo system and compartment should handle outsize cargo and should consider Civil Reserve Air Fleet (CRAF) requirement compatibility.

Perishable cargoes, e.g., dairy produce, fruit, vegetables, flowers, frozen foods, meat, fish, etc., require maintenance of specific temperature ranges during air related door-to-door transportation.

The purpose of this document is to establish minimum operational requirements that will ensure that perishable cargoes in insulated standard airborne containers can be kept in prime condition during the ground handling and air transportation cycle within a maximum time span of 48 h.

This SAE Aerospace Information Report (AIR) provides instructions for intended proper use of Aerospace Standard AS36100A, published 2006-04 [TSO pending], as the technical reference for airworthiness approval of air cargo unit load devices (pallets, nets and containers) to be loaded on board civil transport aircraft. For consistency and cross-checking purposes, it also includes instructions for proper use of previous NAS 3610 [Revision 10, 1990, referenced in TSO C90c], as commonly understood by the industry.

This AS covers the requirements for three sizes of compartment restrained lower deck containers (Unit Load Devices) for the 767 airplane and which do not require airworthiness certification.

This AS covers the requirements for three sizes of compartment restrained lower deck containers (Unit Load Devices) for the 767 airplane and which do not require airworthiness certification. NOTE: IATA Specificaton 50/0, General Technical Requirements and Serviceability limits, should also be taken into account when designing and making equipment according to this Specification as certain provisions contained therein will also be applicable.

The present Aerospace Information Report (AIR) provides a list of the main government regulations, SAE and international standards, and standing industry recommendations applying to air cargo unit load devices (pallets, nets and containers) to be loaded with either baggage or freight on board civil transport aircraft.

The methodology for maximum package size loading is based on a mathematical method allowing the calculation of maximum package size tables. This method does not in principal differentiate between bulk loading and cargo system loading. However, some restrictions have to be considered: Some cargo systems generate pre-determined pallet trajectories. Envelope curves depending on the pallet size and the possible trajectories have to be determined first. Door geometric limitations (with or without cargo loading system) Turning limitations due to weight, load geometry and conveyance capability Securing requirements This document is not intended for airline operational use. It should be used by engineers performing calculations or developing computer programs to produce Maximum Package Size tables specified in AS1825.

The symbols specified in this SAE Aerospace Recommended Practice (ARP) are applicable to all aircraft cargo handling systems for lower deck as well as for upper deck systems. Utilizing the symbols the conveyance, guidance, restraint, power drive unit and the degree of automation for the total cargo handling system can be depicted.
