Scope
This interface standard applies to fuzes/fuzing systems (referred to as fuzing system hereafter) in airborne weapons that use a MIL-STD-1760 type interface. It defines the powers, the discrete signals and the serial data interface for the communications at the interface between the fuzing system and the remainder of the weapon, including the weapon control unit.
The Class 1 interface is an electrical only interface that facilitates use of MIL-STD-1760 type platform store interfaces for the fuze to monitor intentional release and defines the fuze interface bus communications protocol to allow sending and receiving data from fuzing systems.
Class 2 interfaces add a defined connector and additional interfaces to facilitate the exchange of compatible fuzing systems.
Class 3 interfaces add further interface definitions to facilitate the exchange of AS5680A compatible fuzing systems components.
The bus communications protocol provides a means by which the weapon may set mission parameters within the fuzing system main housing and in other devices external to the fuzing system main housing. The standard also defines the target detection signal to be provided by a target detection device external to the fuzing system.
This standard does not address the mechanical interfaces to target detection devices or to other sensors that are external to the fuzing system main housing.
Rationale
Document has been revised to include definitions for the following interfaces: 3 power supply; Initiation inhibit discrete interface; Target detection sensor interface; Post release environment sensor interface. These elements complete the definitions in the Standard of all elements necessary for the Class 2 and Class 3 interfaces for interchangeable fuzes. Also included are a small number of revisions to clarify elements of the previous standard that were unclear (definitions of bit mapping) and corrections to inconsistent tolerance margins.

Issuing Committee
AS-1B Aircraft Store Integration Committee
The SAE AS-1 Aircraft Systems & Systems Integration committee addresses all facets of aircraft avionics systems design, maintenance, and in-service experience. It reviews and develops specifications for stores interface, validation requirements, systems integration, mission store validation plans and media terminal design. Also addressed are system test requirements, architecture, security and 1553 data bus standards. The group is comprised of three subcommittees dedicated to creating, preparing, and maintaining all relevant specifications, standards, and requirements for aircraft avionics systems. These subcommittees include:
AS-1A Avionics Networks AS-1B Aircraft-Store Integration AS-1C Avionic Subsystems Participants in the SAE AS-1 committee include OEMs, suppliers, aircraft avionics equipment companies, consulting firms, government and others across the aerospace and defense industries.Reference

* Redlines comparisons are available for those standards
listed in the Revision History that contain a radio button. A
redline comparison of the current version against a revision is
accomplished by selecting the radio button next to the standard and
then selecting 'compare'. At this time, Redline versions only exist
for some AMS standards. SAE will continue to add redline versioning
with ongoing updates to SAE MOBILUS.
