DO-232 is an air traffic control software standard published by RTCA, Incorporated.

Flight Information Services (FIS) is defined as the non-control information needed by pilots to operate in the US National Airspace System (NAS) and internationally. The timely, efficient exchange of FIS data is required for safety, efficiency and utility in aircraft operations. Pilots, flight planners (e.g., pilots, dispatchers, schedulers), and controllers all need accurate, timely FIS data to plan (or re-plan) and assess the execution of flight operations.
