The Research Of Using HUD To Implement Specially Authorized CAT Ⅱ Operation

The head-up display (HUD) is a new technology of navigation, using computer technology to integrate the ground navigation and flight information display on the head-up display, the pilot can keep heads up state watching the instrument data and navigation data on heads-up-display and follow HUD guidance flight. HUD data and aircraft outside scene display superposition. According to the data indicating Pilots may correct flight status at any time, to achieve fine flight, effectively prevent flight technical error at all kinds of weather conditions. The International Civil Aviation Organization (ICAO) describe the characteristics of HUD in annex6and determine application the technology, requires the civil aviation authority of member countries to improve flight quality and aviation safety by using this technique.China civil aviation in the strategy of "the construction of civil power" and "the twelfth Five Year Plan", clearly pointed out that accelerating the application of new technologies has a positive role and significance to ensure operation safety of civil aviation in the process of sustained and rapid development, and puts forward the overall objectives and requirements, HUD is one of the key projects of which.In2004The Civil Aviation Administration of China started the preparatory work related to the application of HUD, in2005Shandong airlines as a pilot unit began installing HUD in aircraft cockpit. But the process is relatively slow, mainly is the people’s understanding of HUD is not enough, do not understand its benefits. In2012the Civil Aviation Administration of China issued the book-"the application of Chinese HUD roadmap".The HUD in the China aviation application scheduled. This paper introduces the working principle of HUD, analysis of its benefit to civil aviation. Choose a particular airport do the SA CAT II program evaluation.
