A traffic alert and collision avoidance system (TCAS), pronounced / ˈtiːkæs / TEE-kas), also known as an Airborne Collision Avoidance System (ACAS), [1] is an aircraft collision avoidance system designed to reduce the incidence of mid-air collision (MAC) between aircraft.

2025年1月19日 · TCAS is based on secondary surveillance radar (SSR) transponder signals, but It operates independently of ground-based air traffic control (ATC) by monitoring the airspace for nearby aircraft equipped with active transponders. TCAS alerts pilots to potential threats and, in advanced versions, provides instructions to avoid collisions.

2025年2月16日 · ‍ DALLAS — A Traffic Alert and Collision Avoidance System (TCAS), or an Airborne Collision Avoidance System (ACAS), is an anti-collision system that prevents mid-air collisions (MACs) between airplanes. The collision avoidance system is independent of …

2022年8月19日 · How does TCAS work? TCAS stands for Traffic Collision Avoidance System, and its purpose is to minimize the risk of mid-air collisions between aircraft. The ICAO requires all aircraft with a capacity of more than 19 passengers to be fitted with this safety measure.

空中警告和防撞系统 （Traffic alert and CollisionAvoidance System， TCAS ）简称为避撞系统或防撞系统，TCAS 是不依赖地面设备工作的机载设备，通过向同一空域内飞行的、且装有 ATC 应答机 的飞机发射询问信号并接收应答信号，根据询问与应答的延迟时间计算出两机的 ...

空中防撞系统（英文：Traffic Collision Avoidance System，缩写：TCAS）是安装于中、大型飞机的一组电脑系统，用以避免飞机在空中互相冲撞。 现今大部份民航客机都设有空中防撞系统功能。 霍尼韦尔 公司是唯一一家生产所有类型空中防撞系统的制造商，超过一半空中防撞系统产品都是出自该公司。 [1] 伴随着空中交通量的日益增大,空中交通警戒防撞系统（TCAS）在保障飞行安全方面的作用越发的重要。 它能够通过对附近的飞机进行冲突检测,预测未来可能发生的危险,提示 …

TCAS is the product of carefully balancing and integrating sensor characteristics, tracker and aircraft dynamics, maneuver coordination, operational constraints, and human factors in time-critical situations.

2023年2月6日 · The Traffic Collision Avoidance System (TCAS), also known as the Airborne Collision Avoidance System (ACAS), is a critical safety technology for aviation. It is designed to prevent mid-air collisions between aircraft by providing real-time warnings to pilots.

空中防撞系統 （英語： Traffic Collision Avoidance System， 縮寫： TCAS）是安裝於中、大型 飛機 的一組 電腦 系統，用以避免飛機在空中互相衝撞，與 地面迫近警告系統 搭配成為保護飛航安全的兩大防線。 現今大部份 民航客機 都設有空中防撞系統功能。 霍尼韦尔 公司是唯一一家生产所有类型空中防撞系統的制造商，超過一半空中防撞系統产品都是出自该公司 [1]。 早在1950年代航空業界就開始著手研究空中防撞系统，但因技術問題，應用不普遍。 直到80年代，經歷多次空 …

Traffic collision and avoidance system (TCAS) uses an aircraft’s transponder to interrogate and receive replies from other aircraft in close proximity. The TCAS computer alerts the pilot as to the presence of an intruder aircraft and displays the aircraft on a screen in the cockpit.
