| 6. | So the aviation has installed the ground proximity warning system ( gpws ) on aircrafts since the middle of 1970s , and now is the enhance ground proximity warning system ( egpws ) . this paper describes the development , components , principle and the features of the communication navigation surveillance / air traffic management ( cns / atm ) , the traffic alert and collision avoidance system ( tcas ) , ground proximity warning system ( gpws ) , and / or the enhance ground proximity warning system ( egpws ) . it particularly discuses the positive effect that ads tcas / tcas2 and gpws / egpws take on cfit and middle _ air collision . integrating with the aircrafts type . the instances and the accidents . this paper analyzes the present problems in the field of air traffic management and the new technologies resolving these problems . so that we can improve the flight safety effectively
本文论述了新航行系统( cns atm ) 、空中交通警戒与防撞系统( tcas tcas2 )以及近地警告系统( gpws )和增强型近地警告系统( egpws )的发展、组成原理及其功能特点，着重讨论了自动相关监视( ads ) 、 tcas tcas2和gpws egpws在保证飞行安全、防止空中相撞和可控飞行撞地事故中所起的积极作用，并结合具体机型和事故事例，分析了事故发生的原因和目前存在的问题，对系统提出了进一步改进的可能，以期进一步保证飞行安全。

| 7. | The traffic alert and collision avoidance system ( tcas ) is a system independent of ground equipment , which is used to avoid middle - air collision . this system can detect all the aircrafts equipped with the atc transponder within a range . it provided traffic advisory to the pilot if some aircrafts close to it , and also provides vertical resolution advisory to the pilot to avoid collision
Tcas是一种不依赖地面设备的空中交通防撞系统，它能够探测在其领域内装有空中交通管制应答机( atc )的任何飞机，向驾驶员报告潜在的相撞目标，并发出垂直防撞指令。
