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.
Non-discrete mode A code reserved use in mode S radar/ADS-B environment where the aircraft identification will be used to correlate the flight plan instead of the mode A code. [1] US: Used exclusively by ADS-B aircraft to inhibit mode 3A transmission. [3] US: Non-discrete code assignments in accordance with FAA Order JO 7110.65, 5-2.
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.
Technology that alerts pilots of other aircraft may have been disabled before crash, expert explains. January 30, 2025 at 12:19 PM. ... [Traffic Alert and Collision Avoidance System] which would ...
When ground-based radar equipment [9] receives the IDENT bit, it results in the aircraft's blip "blossoming" on the radar scope. This is often used by the controller to locate the aircraft amongst others by requesting the ident function from the pilot, e.g., "Cessna 123AB, squawk 0363 and ident". [6] [7]
International Civil Aviation Organization Doc 4444 requires that radar systems should provide for the display of safety-related alerts including the presentation of minimum safe altitude warning. [2] The radar equipment predicts an aircraft’s position in 2 minutes based on present path of flight, and the controller issues a safety alert if ...
The Runway Awareness and Advisory System (RAAS) is an electronic detection system that notifies aircraft flight crews on the ground of their position relative to their allocated runway. It is a type of Runway Situation Awareness Tool (RSAT).
The National Transportation Safety Board has issued an urgent warning to airlines that fly the Boeing 737, saying a failure first seen on a United Airlines flight in February could cause problems ...
