Program Description

Advanced Technologies & Oceanic Procedures (ATOP)

The Advanced Technologies & Oceanic Procedures (ATOP) system is the most advanced mixed mode air traffic control (ATC) system in the world and is in full operation in the three Federal Aviation Administration (FAA) Oceanic ATC facilities. The system has a fully integrated conflict probe, datalink communications, automatic processing of mixed mode position reporting and has introduced controllers to a concept of managing aircraft by exception. ATOP automates routine activities so that the controllers are able to focus on only the "out of the ordinary" activities, ATOP provides a very advanced platform to experiment and implement concepts for the future Next Generation Air Transportation System (NextGen).

Key Capabilities
