The flight crew referenced the quick reference handbook, identified the malfunctioning air data computer and contacted company operations and maintenance departments. The flight crew decided to return to KJFK, then declared an emergency and coordinated with the ATS for the air turnback to KJFK where a landing was made without further incident. Maintenance replaced the first officer side air data module, conducted a pitot static system test, and the aircraft was returned to service."
