FIX - Flight Information eXchange Protocol Specification Initiative

• To publish and promote the flight information data protocols supported by common Electronic Flight Information Systems and related devices.
• To work towards common protocols that support multi-vendor device interoperability and the development of third-party support devices.
• Targeted to the non-certified aircraft industry only.
• Not a standards organization, participation and compliance is strictly voluntary

• Collect and publish known protocols from all EFIS and related device vendors that wish to participate.
• Publish planned new protocols and seek comments and suggestions from all interested parties.
• Facilitate agreement on code points that will allow unique delineation and multiplexing of multiple protocols from multiple vendors on a single data link.
• Wherever possible, eliminate duplication of protocols by adopting or enhancing existing protocols.
• Wherever possible, ensure protocols are human readable (text based).

• Collect and publish existing and newly developed protocols in a single location (this web site) to allow for easy access and comparison
• Publish newly planned protocols in a timely fashion to seek comments that lead to improvements and multi-vendor support
• Coordinate multi-vendor cooperation.
• Seek end-user requests for new features and functions.
