The standard covers the three USAF prime mission cargo aircraft (C-130, C-141B, and C-5) as well as the cargo aircraft in the long range international segment of the Civil Reserve Air Fleet (B-747), DC-10, B-707, and DC-8). The structural and dimensional criteria for other cargo aircraft are documented in specific manuals for each aircraft. % The format of this document incorporates the basic standard containing general and detail requirements with associated verification criteria, and administra- . tive information. Two appendices supplement the basic standard. Appendix A, User Handbook for MIL-STD-1791, contains the rationale, guidance, and lessons learned for both the detail requirements and verification criteria. Appendix B, Air Transportability Design Information, consists of multiple sections. The first section presents general info~ation on the military aircraft features and limits, restraint criteria and applications, and unit load device design. The next three sections present C-130, C-141B, and C-5 structural and dimensional criteria and cargo item considerations. The last section covers load planning for the Civil Reserve Air Fleet (CRA.F)(TO-1-C-XXX-9). For other military aircraft, refer to that aircraft’s dash 9 loading manual. For other commercial aircraft, refer to the specific aircraft weight and balance manual. @ A particularly useful feature of Appendix A is a matrix showing’ design requirements appropriate to various types of cargo item configurations. It is intended as a guide for the user in determining which criteria should be con- sidered for a particular design situation. User comments are solicited in an effort to improve this feature. ... 111 MIL-STD-1791 (USAF) 31 October 1985 1. SCOPE 1.1 Ceneral. This standard covers general design and performance require- ments of military equipment for internal air transport in military prime mission cargo aircraft and the long range international segment of the Civil Reserve Air Fleet (CRAP). This standard also contains general design and per- formance requirements for military equipment to be airdropped from Air Force cargo aircraft. The complete air transportability and airdrop requirements for an item of equipment not specified herein shall be specified in the indi- vidual equipment specification. 1.2 Applicability. The requirements and tests contained in this standard apply to the internal air transportability and airdrop aspects of all items intended for aerial delivery in CRAP or USAF aircraft. They represent the minimum acceptable transportability and airdrop features. When it is known that the equipment will require features that are more restrictive then those stated herein, the more stringent features will be specified in the individual equipment specification. 1.3 Deviations 1.3.1 Design improve~nt.. Any projected design that will improve perform- ancee, safety, or reliability or reduce life cycle and end item cost through deviations from this standard, or where the requirements of this standard result in a compromise of the item for the sake of air transportability or airdrop, shall be brought to the attention of the procuring activity for con- ● sideration. 2.
