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 ...
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.
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 ...
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 ...
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 ...

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.
Overview. The ACD Network is a train-collision prevention system invented by Rajaram Bojji and patented by Konkan Railway Corporation, a public-sector undertaking of the Ministry of Railways, government of India . Anti-collision devices were found to be effective in the Southern Railway zone after a brief trial. [citation needed]
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 ...
