APIM 08-004A: Cockpit Display System Interface - Supp 6 to ARINC 661 (pdf, 298K)
APIM 08-004B:
Cockpit Display System Interface - ARINC 661 Part 2 (pdf, 62K)

Goal: Develop flight deck display interface standard for primary display and related applications (e.g., FMS). Support new airplane development programs including Airbus A380, A350, and A400M, and Boeing 787, 737MAX, KC-46A, and B777X. Ensure growth for CNS/ATM applications that provide advanced operational concepts that will increase aviation safety, capacity, and efficiency.

Scope: ARINC 661, Cockpit Display System Interfaces to User Systems, is being expanded to meet OEM requirements for new airplanes. ARINC 661 defines a Graphical User Interface (GUI) to displays. It also defines GUI objects. ARINC 661 will enable flight crews to interact with the CDS using a cursor control device.

Benefit: Both Airbus and Boeing have embraced the ARINC 661 concept for their latest aircraft. Because ARINC 661 is media independent, broad use of ARINC 661 beyond air transport markets is anticipated. This project will provide airlines with a standardized avionics interface to the cockpit display system. By having a standardized interface, avionics development can be concurrent with display system development.

Work Program:

The AEEC endorsed CDS work program is presently developing Supplement 6 to
ARINC 661 and Part 2 to ARINC 661.

New material will include:

  • Additional new widgets and widget extensions
  • Touch screen capabilities
  • Synthetic vision
  • Three dimensional projection
