ABOUT THIS DOCUMENT
The 8730L Series Aircraft Interface Device (AID) provides an interface between various aircraft avionics systems
and nontraditional avionics equipment such as Electronic Flight Bags (EFB), In-Flight Entertainment (IFE)
Systems, broadband communications systems (cellular, Wi-Fi) or onboard network servers; providing both a
hardware and software firewall protecting the critical aircraft systems against any adverse effect from the
interfacing nontraditional equipment.
The AID incorporates a variety of industry standard interfaces; including Ethernet, ARINC 429, ARINC 717, RS-
232, RS-422/485, USB, and Discrete inputs/outputs. The AID also provides a removable mass data storage
device enabling local data storage to hosted applications. An optional embedded cellular or Wi-Fi radio using
remote antennas is available.
The AID incorporates a Linux operating system running on a PowerPC based micro-processor utilizing DDR3
memory. Software supports avionics interface data reception, transmission, concentration, and recording. Access
to this data is provided to locally hosted or remote equipment applications via a built-in ARINC 834 server.
