As the congestion of air traffic rises, there is a greater strain put on air traffic control (ATC) to safely manage an air space.
The Future Air Navigation System (FANS) data link technology, Controller Pilot Data Link (CPDLC) and Automatic Dependant Surveillance Contract (ADS-C) is implemented in both oceanic and domestic airspace around the world. These technologies assist in significantly reducing pilot and ATC workload whilst increasing safety and efficiency.
The positioning of an aircraft by ATC is reliant on messages it receives from the aircraft. Considering that ATC messages are not given priority over other data link messages that are delivered by the same path e.g. Aeronautical Operational Control (AOC) flight plan uplinks, there is a need to verify that the transit time of ATC messages meet the requirements for current reduced separation standards. Additionally it should be evaluated that the data link performance is correct throughout its service volume.
This paper will look into the real life experiences of flight inspection of ADS-C and CPDLC. It will summarise the flight inspection organisation requirements, explore what technology is available to allow organisations to meet these requirements and discuss the actual inspection results and how they relate to validating the Required Navigation Performance (RNP), and Required Communication Performance (RCP).
