本文回顾了十年来航空公司应用数字机载设备的经验,并列举了八十年代应用主动控制,先进的座舱和先前的空中交通管制(ATC)等技术所获得的好处。大多数越洋商用航空运输机的驾驶员积累了大约十年应用数字机载设备的经验,其中包括从极其简单的(ARINC 579甚高频全向信标(VOR))到复杂的(大气数据计算机(ADC)、区域导航(ANA),惯性导航系统(INS))。这种数字设备的使用经验不仅取得了很高的成本效益,而且还使航空公司和生产厂家确立了进一步把数字技术用于航空电子的信心。现在,采用数字飞行引导系统的DC9 Super 80已营业使用,不久其他飞机也将采用新的ARINC 700系列机载设备。数字化设备不仅本身具有高成本效益的特点,而且还能提高飞机和动力系统的效率。因此可在八十年代后半期得到进一步应用。
This article reviews airlines’ experience with digital airborne equipment over the past decade and cites the benefits of proactive controls, advanced cockpits and previous air traffic control (ATC) technologies from the 1980s. Most pilots of commercial trans-ocean aircrafts have accumulated about a decade of experience using digital airborne equipment, ranging from extremely simple (ARINC 579 Very High Frequency Beacon (VOR)) to sophisticated (Air Data Computer (ADC ), Regional navigation (ANA), inertial navigation system (INS)). Not only has this digital device experience been used cost-effectively, it has also enabled airlines and manufacturers to establish the confidence to further use digital technologies in avionics. The DC9 Super 80, now powered by the digital flight guidance system, is now in commercial use and soon the other aircraft will also use the new ARINC 700 Series airborne equipment. Not only is digital equipment itself cost-effective, it also increases the efficiency of aircraft and powertrain systems. So it can be further applied in the second half of the eighties.
