  3. Survival, Evasion, Resistance and Escape - Wikipedia

    en.wikipedia.org/wiki/Survival,_Evasion...

    Level C training focuses on resistance to exploitation and interrogation, survival during isolation and captivity, and escape from hostiles (e.g., "prison camps"). "Escape Training" has elements similar to evasion and resistance training – if details are revealed, it potentially helps adversaries.

  4. Ground proximity warning system - Wikipedia

    en.wikipedia.org/wiki/Ground_proximity_warning...

    A CFIT accident is one where a properly functioning airplane under the control of a fully qualified and certified crew is flown into terrain, water or obstacles with no apparent awareness on the part of the crew. Beginning in the early 1970s, a number of studies examined the occurrence of CFIT accidents.

  5. 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.

  6. 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 ...

  7. Terrain awareness and warning system - Wikipedia

    en.wikipedia.org/wiki/Terrain_awareness_and...

    In aviation, a terrain awareness and warning system ( TAWS) is generally an on-board system aimed at preventing unintentional impacts with the ground, termed "controlled flight into terrain" accidents, or CFIT. [1] The specific systems currently in use are the ground proximity warning system (GPWS) and the enhanced ground proximity warning ...

  8. Automated emergency braking system - Wikipedia

    en.wikipedia.org/wiki/Automated_emergency...

    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. A collision avoidance system by steering is a new concept. It is considered by some research projects.

    On March 17, 2012, the round was held at the 17-turn 3.74 mi (6.02 km) Sebring International Raceway road course in Sebring, Florida. [5] [6] The event was sanctioned by the International Motor Sports Association (IMSA), with officials from both the ALMS and the WEC on site.

  10. 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 ...

  11. 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]

  12. Traffic collision avoidance system - Wikipedia

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

    A traffic alert and collision avoidance system (TCAS, pronounced / t iː k æ s /; TEE-kas), is an aircraft collision avoidance system designed to reduce the incidence of mid-air collision (MAC) between aircraft.
