After the incident , the civil aviation department immediately issued instructions reminding air traffic control officers of radar control techniques and requested them to continue to be vigilant and to take every possible step to ensure flight safety 民航处在事发后已即时向航空交通管制员发出指引，提醒他们所需采用的雷达管制技巧，并且指令他们继续提高警觉，以及采取所有步骤确保飞行安全。
In order to make the terminal airspace moderated and consisted , and acquire the biggest capacity of airport , we must consider the influencing factors as many as possible , it is our final target to plan the airspace in beijing terminal unify . with the conditions that the current operation modes of parallel runway , approach and departure procedures and terminal airspace in beijing international airport , this article has analyzed the reasons of airspace congestion . this article also applies the theory of instrument flight procedure and utilizes the current facilities in beijing international airport . the design of flight procedures combining rnav procedures with instrument approach procedures may be accepted on some routes . it make the approach and departure procedure more effective , and increase the capacity of the airport more or less ; secondly , this article contrast the capacities of parallel runway in different methods under radar control , and make the conclusion that the parallel runway in dependent operation modes has the biggest capacity 本文从目前首都机场平行跑道的运行方式、进离场程序、终端区空域的现状入手，剖析了造成空域紧张的原因，应用仪表飞行程序设计的思想和原则，利用首都机场终端区现有的设施，某些航线可采用区域导航( rnav )程序与仪表进近程序相结合的飞行程序设计，优化了目前首都机场的进离场程序，在一定程度上增加了机场容量；其次，研究了雷达管制条件下平行跑道不同运行方式的容量对比，得出平行跑道独立运行的容量最大，然后以这种这种运行方式，为首都机场设计出了平行跑道独立运行的飞行程序；最后，分析北京终端区各机场空域对首都机场飞行程序安全、有效运行的制约因素，研究设计出了北京终端区规划方案及规划后的飞行程序和飞行方法，以达到增大机场的容量，适应未来航班量增加的需求。
She has been removed from operational duties and re - deployed to an office post . she will be placed under close supervision for assessment of suitability and be required to undergo intensive simulator training before undertaking operational duties again at a later date , " the spokesman said today ( friday ) 处方已将她从雷达管制岗位调往执行办公室职务，并会密切监察其工作表现来评估她是否适合在稍后重新执行雷达管制职务，以及安排她接受密集的模拟训练，才会让她重返工作岗位。
Wake vortex separation standards are used to prevent hazardous wake vortex encounters which mainly found in the final approach course within the airport termination zone . firstly , this paper analysis the mechanism of the vortex decay and research the influence on the safety of the flight ; then . several different radar wake vortex separation standards are compared and some basic guidelines are developed to establish the future vortex standards . in addition , one kind of advance vortex classification for the civil airplane is proposed . secondly , an encounter hazard model which established for the following aircraft and a simple vortex decay model which mostly concern with the proceeding one are developed ; and a safe separation model can be derived from the both . finally , through the simulation calculation , the correctness of the vortex classification of different types of aircrafts are tested and proved 本课题对雷达管制条件下的最小尾流间隔标准进行了较为详细的分析和研究；首先对尾流的形成和消散机理以及尾流对飞行安全的影响做出了详细的分析，然后就目前实行的几种不同的最小尾流间隔标准进行了比较和分析，提出了相关的几条准则和一种改进的机型尾流分类标准；在这之后，采用理论分析和统计数据分析相结合的方法，建立了尾流危险遭遇基本模型和尾涡消散模型；并在此基础上对民用航空不同机型的尾流分类的合理性进行了计算和评估，为最小尾流间隔标准的确定和改进提供了初步的理论依据。
In response to press reports today ( tuesday ) on an air traffic control incident on january 22 , a spokesman for the civil aviation department said that contrary to what was reported in some newspapers , initial findings indicated that the radar controller attempted to carry out corrective actions when the conflict was evident 民航处发言人回应今日(星期二)报章报导一月二十二日所发生的一宗航空交通管制事件时表示，与部分报章报导相反，民航处初步调查显示与事件有关的雷达管制员在事发时已采取步骤试图纠正事件。
