A traffic alert and collision avoidance system ( TCAS, pronounced / tiːkæs /; TEE-kas ), is an aircraft collision avoidance system designed to reduce the incidence of mid-air collision (MAC) between aircraft. It monitors the airspace around an aircraft for other aircraft equipped with a corresponding active transponder, independent of air ...
Survival handbook of the United States Army Air Forces (USAAF) from 1944. Survival, Evasion, Resistance, and Escape ( SERE) is a training program, best known by its military acronym, that prepares U.S. military personnel, U.S. Department of Defense civilians, and private military contractors to survive and "return with honor" in survival ...
A ground proximity warning system ( GPWS) is a system designed to alert pilots if their aircraft is in immediate danger of flying into the ground or an obstacle. The United States Federal Aviation Administration (FAA) defines GPWS as a type of terrain awareness and warning system (TAWS). [1] More advanced systems, introduced in 1996, [2] are ...
The Automatic Ground Collision Avoidance System (Auto-GCAS) enhances safety by mitigating controlled flight into terrain (CFIT) accidents. [1] The Auto-GCAS team was awarded the 2018 Collier Trophy for the design-integration and flight testing in the F-35, marking the year's greatest achievement in aeronautics. [2]
An airborne collision avoidance system ( ACAS, usually pronounced as ay-kas) operates independently of ground-based equipment and air traffic control in warning pilots of the presence of other aircraft that may present a threat of collision. If the risk of collision is imminent, the system recommends a maneuver that will reduce the risk of ...
Autonomous: the system acts independently of the driver to avoid or mitigate the accident. Emergency: the system will intervene only in a critical situation. Braking: the system tries to avoid the accident by applying the brakes. Time-to-collision could be a way to choose which avoidance method (braking or steering) is most appropriate.
Aviation accidents and incidents. An aviation accident is an event during aircraft operation that causes serious injury, death, or destruction; an aviation incident is any operating event that compromises safety but does not progress to an actual accident. Preventing accidents and incidents is the main goal of aviation safety .
A runway incursion is an aviation incident involving improper positioning of vehicles or people on any airport runway or its protected area. When an incursion involves an active runway being used by arriving or departing aircraft, the potential for a collision hazard or Instrument Landing System (ILS) interference can exist.
A collision avoidance system ( CAS ), also known as a pre-crash system, forward collision warning system ( FCW ), or collision mitigation system, is an advanced driver-assistance system designed to prevent or reduce the severity of a collision. [2] In its basic form, a forward collision warning system monitors a vehicle's speed, the speed of ...
In transportation, collision avoidance is the maintenance of systems and practices designed to prevent vehicles (such as aircraft, motor vehicles, ships, cranes and trains) from colliding with each other. Examples include: Airborne collision avoidance systems for aircraft. Automatic Identification System for collision avoidance in water transport.
