    The Airport Movement Area Safety System (AMASS) visually and aurally prompts tower controllers to respond to situations which potentially compromise safety. AMASS is an add-on enhancement to the host Airport Surface Detection Equipment Model 3 (ASDE-3) radar that provides automated aural alerts to potential runway incursions and other hazards.

    They operate as an additional layer of safety, independent of human-issued air traffic control clearances. [1] The system works by processing traffic position and movement data generated by transponders aboard aircraft and airside ground-vehicles such as aircraft rescue and firefighting (ARFF) units, aircraft tugs, and snow-clearing equipment.
