SAE AS6165 2012 Edition, December 1, 2012 Interface Standard, Airborne EO/IR Systems, Maintenance and Test
Quantity

Description / Abstract: This standard defines the use of data interfaces between a host platform and an electro-optic/infrared (EO/IR) system for maintenance and test (MT) purposes. In particular, this standard defines the use of the data interfaces in order to facilitate the:

a. confirmation of system performance and function;

b. external initiation of built-in-test (BIT) functions;

c. performance of other diagnostic tests of system health;

d. downloading MT data;

e. uploading software changes.

This standard does not cover mechanical or electrical interfaces, nor does it define the basic platform-to-sensor communication protocols and formats. Furthermore, this standard does not address software changes that are made by the manufacturer and not accessible at the sensor interfaces. Data protocols and formats are covered by AS6135. Electrical interfaces are covered by AS6129. This standard covers the use of the interfaces defined by AS6129 and AS6135 for the purposes described herein.

Purpose

The intent of this standard is to enhance interchangeability and interoperability amongst equipment provided by various EO/IR system vendors and associated electronic systems with respect to MT of the system during its development and employment. In so doing, this standard will reduce acquisition and life cycle costs associated with EO/IR system acquisition and integration and reduce the costs and proliferation of maintenance support equipment and associated software and training. Furthermore, it is envisioned that the ability to fully exercise the sensor system and download all relevant data while installed on the aircraft ("platform") will permit more robust assessment of system health without requiring deinstallation of the turret or associated electronics.

Application

This standard applies to platforms and EO/IR systems that interface with each other. Initial release of this document will address turreted EO/IR systems with future releases addressing other classes of EO/IR systems such as pods and warning sensors. This standard is applicable both to the development of new sensors and platforms as well as to upgrades to existing platforms or sensors.
