MIL-HDBK-258

Abstract

This handbook establishes the physical and functional interface for aircraft installation of the AN/AAS-36 infrared detecting set (IRDS). The physical and electrical Interfaces are defined for the IRDS supplier, the airframe contractor and the operational program. <br>The defined interfaces establish the compatibility between cofunctioning elements and control the interface design. Any changes in these areas may affect the installation compatibility or operation. Contemplated changes affecting any of the defined area must be coordinated with all custodial and review activities. <br>The AN/AAS-36 IRDS was designed and is fabricated by Texas Instruments. Intended airborne installation of the IRDS is for either retractable or fixed turret applications for such aircraft as P-3B, P-3C, S-3A, etc. Target tracking by the IRDS is either manual or computer controlled, via on-board data processing systems, when applicable. Lockheed Aircraft Company designed and fabricates a turret retraction mechanism for P-3C IRDS installations. NADC developed the necessary software programs to control IRDS tracking for this configuration. <br>The AN/AAS-36 interfaces with data processing systems such as the AN/AYA-8 [MIL-D-81347C(AS)] and AN/ASQ-m(V) [MIL-C-81332B(AS)], a synchro to digital converter such as the CV-2461 A/A [MIL-C-81344(AS)], aircraft power and lighting supplies and aircraft maintenance control devices.
