Air Traffic Services Unit (ATSU) Airline Operational Communication

Overview
The Air Traffic Services Unit (ATSU) provides the Datalink Host Platform, Router and Air Traffic Control applications used for Datalink communications on the Airbus A318, A319, A320, A321, A330 and A340 aircraft. The Honeywell ATSU Airline Operational Control (AOC) software and database support operational functions include:
  • AOC uplinks and downlinks that enable efficient airline operations
  • Out-off-on-in (OOOI) logic to define each flight phase
  • AOC user interface to the flight crew
  • Aircraft and operational data reporting—including engine, fuel, avionics and maintenance reports
Honeywell’s ATSU AOC software functionality is configured within a user-modifiable AOC Database. The AOC Database can be tailored directly by Honeywell customers using the ACARS Reconfiguration Tool or by the Honeywell Datalink Services team. AOC Databases are loadable on-wing and do not require aircraft certification (TC or STC).

Three components make up the ATSU system:
  • The ATSU Hardware on Airbus platforms – provided by Airbus
  • The ATSU Aircraft Interface Software (including air/ground Router) and ATC Application - provided by Airbus
  • The ATSU AOC software and AOC Database – provided by Honeywell
