基于机场Type Ⅰ ILS设备进行CAT Ⅱ ILS试飞的可行性研究

The Feasibility Study for CAT Ⅱ ILS Flight Test with Type Ⅰ ILS

进行CATⅡILS试飞的前提是机场具备TypeⅡILS设备,国内符合条件的机场皆为大型枢纽机场,诸多运行限制将极大影响试飞效率。为了增加机场选择裕度,加快试飞进程,在国内首次提出采用具有TypeⅠILS进行CATⅡILS试飞的新方法,并从适航条款、技术要求等方面详细分析其可行性。结果表明:此方法满足适航审定要求,切实可行,是一种有效的能实际运用于国内大多数Ⅰ类运行条件机场的试飞方法。

Airports with TypeⅡILS is the precondition of CATⅡILS flight test.Since domestic airports with CategoryⅡoperation condition are all large hub airports,many restrictions will greatly affect the efficiency of flight test.In order to increase the airports selection margin,and accelerate the test process,a new method of car-rying out CATⅡILS flight test with TypeⅠILS in domestic is firstly proposed.The research results show this new method can meet the requirements of airworthiness certification,and is feasible.It is an effective flight test method that can be applied to most airports with CategoryⅠoperation condition in domestic.
