10.2Format.The format shall be in accordance with STANAG AAP-3, Procedures for Development, Preparation, Production, and the Updating of NATO Standardization Agreements (STANAGs) and Allied Publications (APs), Chapters 4 and 5.
10.2.1Sections.Arabic numbers shall be used to number sections throughout the publication. Each section shall be separated from the next section in a manner that is easily accessible (e.g. tab dividers).
10.3Content.This AOP shall contain interface data for NATO aircraft, stores, and suspension equipment. Interface control drawings shall disclose engineering form, fit, function, and performance requirements for the acquisition of interchangeable purchased items of existing designs, or of items specially developed by vendors to the control drawing requirements. Control drawings shall permit the acquisition of vendor developed items from specialized segments of industry without disclosing details of design or divulging proprietary vendor data. Vendor Item drawings shall depict existing commercial items or vendor developed items advertised or catalogued as available on an unrestricted basis as an "off-the-shelf" item or an item, while not commercially available, is procurable from a specialized segment of industry. Such drawings shall illustrate the ground fit and compatibility tests performed in accordance with STANAG 3899 AA. The following volumes and their respective sections may be included in the AOP:
