LTN—92激光陀螺惯导系统。美国西北航空公司最近向利顿公司订购了9套LTN-92激光陀螺惯导系统,安装到3架刚采购的DC-10-30飞机上。同时,中国航空公司将把这套系统安装到它的4架波音747-200飞机上,以取代旧的LTN-72挠性陀螺惯导系统。德国汉莎技术公司也订购了3套LTN-92,用来安装在1架沙特阿拉伯的波音747飞机上,取代旧的LTN-72RL惯导系统。另一套带可移动的插头LTR-97垂直/方位陀螺已被选用来改装石油公司机群中往返于油田之间运输的2架波音737飞
LTN-92 laser gyro inertial navigation system. Northwest Airlines recently ordered nine LTN-92 laser gyro inertial systems from Litton for installation on three newly purchased DC-10-30s. In the meantime, Air China will install the system on its four Boeing 747-200 aircraft to replace the older LTN-72 flexible gyroscope. Lufthansa Technik Germany also ordered three LTN-92s to be installed on a Boeing 747 in Saudi Arabia to replace the older LTN-72RL inertial navigation system. Another set of plugs with removable LTR-97 vertical / azimuth gyros have been chosen to retrofit two Boeing 737s flew back and forth between oil fields to the fleet of oil companies
