AIRCRAFT INTERFACE DEVICE (AID) ARINC759

This document sets forth the characteristics of an Aircraft Interface Device (AID) intended for installation in commercial aircraft. The intent of the document is to provide general and specific design guidance for the development of an AID for use in retrofit applications associated with aircraft typically developed between the mid-1970s through the 1990s, that primarily utilize ARINC 700 series avionics, and that interface with the aircraft via ARINC 429 and ARINC 717 unidirectional buses and Hi/Lo discrete signals. This document describes the desired operational capability of the AID and the standards necessary to ensure interchangeability.
