  3. Traffic collision avoidance system - Wikipedia

    en.wikipedia.org/wiki/Traffic_collision...

    Traffic collision avoidance system. 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 ...

  4. Collision avoidance system - Wikipedia

    en.wikipedia.org/wiki/Collision_avoidance_system

    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.

  5. Avoidance learning - Wikipedia

    en.wikipedia.org/wiki/Avoidance_learning

    An avoidance response is a natural adaptive behavior performed in response to danger. Excessive avoidance has been suggested to contribute to anxiety disorders, leading psychologists and neuroscientists to study how avoidance behaviors are learned using rat or mouse models. [1] Avoidance learning is a type of operant conditioning (also known as ...

  6. Defensive driving - Wikipedia

    en.wikipedia.org/wiki/Defensive_driving

    A driver safety program called the Driver Example Program was developed in 1964 by Chris Imhoff of the (US) National Safety Council. The program instituted a Defensive Driving Course (DDC). Defensive Driving Courses, along with Instructor Development Courses were offered beginning 1964 and 1965, typically through corporate sponsorships.

  7. Airborne collision avoidance system - Wikipedia

    en.wikipedia.org/wiki/Airborne_collision...

    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 ...

  8. Traffic collision reconstruction - Wikipedia

    en.wikipedia.org/wiki/Traffic_collision...

    Traffic collision reconstruction is the process of investigating, analyzing, and drawing conclusions about the causes and events during a vehicle collision. Reconstructionists conduct collision analysis and reconstruction to identify the cause of a collision and contributing factors including the role of the driver (s), vehicle (s), roadway and ...

    The Survival, Evasion, Resistance and Escape (SERE) School (A-2D-4635 or E-2D-0039) at CENSECFOR Detachment SERE East, Portsmouth Naval Shipyard, New Hampshire offers several SERE courses including the outdoor/field course at the Navy Remote Training Site, Kittery, Maine, a "Risk of Isolation Brief" course, and the SERE Instructor Under ...

  10. t. e. The Maneuvering Characteristics Augmentation System ( MCAS) is a flight stabilizing feature developed by Boeing that became notorious for its role in two fatal accidents of the 737 MAX in 2018 and 2019, which killed all 346 passengers and crew among both flights. Because the CFM International LEAP engine used on the 737 MAX was larger and ...

  11. Portable collision avoidance system - Wikipedia

    en.wikipedia.org/wiki/Portable_collision...

    A portable collision avoidance system (PCAS) is an aircraft collision avoidance system similar in function to traffic collision avoidance system (TCAS). TCAS is the industry standard for commercial collision avoidance systems but PCAS is gaining recognition as an effective means of collision avoidance for general aviation and is in use the ...

  12. Collision avoidance in transportation - Wikipedia

    en.wikipedia.org/wiki/Collision_avoidance_in...

    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
