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 ...
The U.S. Army Combat Readiness Center (USACRC) is a United States Army organization. The Army Safety Team provides safety and risk management expertise to the Army, DoD, and other agencies; develops, maintains and evaluates Army Safety policy and programs; and communicates relevant risk management information to Army Leaders for the preservation of our Soldiers, Civilians, Families and vital ...
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 the ...
Collision avoidance in transportation. A simple collision avoidance system. 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. They perceive the environment with sensors and prevent collisions ...
Survival handbook of the United States Army Air Forces (USAAF) from 1944. Survival, Evasion, Resistance, and Escape (SERE) is a training concept originally developed by the United Kingdom during World War II. It is best known by its military acronym and prepares a range of Western forces to survive when evading or being captured.
The United States Army Air Assault School (officially, the Sabalauski Air Assault School, or TSAAS), is an Army Forces Command Table of Distribution and Allowances unit located at Fort Campbell, Kentucky. Its primary task is training leaders and soldiers assigned to the 101st Airborne Division (AASLT), other United States Army units, and United ...
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.
The vortex ring state (VRS) is a dangerous aerodynamic condition that may arise in helicopter flight, when a vortex ring system engulfs the rotor, causing severe loss of lift. Often the term settling with power is used as a synonym, e.g., in Australia, the UK, and the US, [2][3][4] but not in Canada, which uses the latter term for a different ...
