ARINC 661 Overview

•

A standard which aims to normalize the definition of a Cockpit Display System (CDS), and the communication between the display and User Applications (UA) which manage aircraft avionics functions

ARINC 661 Overview

•

Borne from requirements derived by the avionics industry
– Aircraft manufacturers and suppliers
• Airbus, Boeing GE, Honeywell, Rockwell Collins, Dassault
–

Initial version released 2001
• First adopted on Airbus A380
• Five supplements released subsequently through 2013

–

Objectives called out explicitly by A661 Committee

–

Minimize costs for new display capabilities

–

Minimize costs for changes to new display capabilities

–

Minimize costs for the management of hardware obsolescence

–

Support the means of developing standard HMI

COTS Solutions

•

Market trend is toward ubiquitous adoption in commercial aerospace
– Military leveraging economies of scale to achieve similar economic goals

•

Elegant but not trivial
– Introduces a technology overhead not related to core avionics capabilities

•

Does not currently enhance cockpit display feature/function/capability
– Promotes consistent UI “look and feel”
– Enables modification without re-certification

•

Leveraging COTS for tools and certification mitigates risk

COTS Solutions

•

Why a COTS Solution?
– Provide specialized tools that enable new concepts and paradigms
–

COTS solutions reach a broad user base providing more feedback into design and evolution which promotes best practices

–

Reduces Total Cost of Ownership

–

Turn key solutions

–

Commercial certification support

–

Supports and promotes reusability
