Autonomous runway incursion warning system (ARIWS) is a system which provides autonomous detection of a potential incursion or of the occupancy of an active runway and a direct warning to a flight crew or a vehicle operator.
ARIWS uses available surveillance data but operates independently from ATC systems or controller input to monitor the actual situation on a runway and to autonomously generate visual alerts in accordance with the motion and velocity of the detected traffic in the form of airfield lighting displayed directly to flight crew and vehicle operators.
These systems act as a visual verification of an occupied runway. They create an additional layer of runway safety that aids to increase situational awareness for pilots and vehicle drivers that the runway is not safe.
IFATCA Policy is:
IFATCA fully supports and encourages the future development of Autonomous Runway Incursion Warning Systems provided the following criteria are met:
If ARIWS activations are displayed to the controller, the information shall be efficiently incorporated at the appropriate control positions. Legal responsibilities shall be clearly and unambiguously defined.
