民用飞机飞行操纵系统对CCAR25.671(d)条款符合性的适航验证方法分析

CCAR25.671(d)规定飞机的设计必须使其在所有发动机都失效时仍可操纵.针对中国民用航空总局颁发的运输类飞机适航标准(CCAR25部)的上述要求,某民用飞机对其飞行操纵系统提出了采用试飞(MOC6)和工程模拟器(MOC8)试验验证的方法.首先阐述了美国FAA航空规章制定咨询委员会(ARAC)对CCAR25.671...

Analysis of Compliance Methods for CCAR25.671(d) for Flight Control System of Civil Aircraft

CCAR25.671（d） specifies that the airplane must be designed so that it is controllable if all engines fail. Aiming at the above requirement specified in Transport Category Airplanes Airworthiness Standards issued by Civil Aviation Administration of China, compliance methods of Flight tests （MOC6） and Engineering Simulator Tests （MOC8） are proposed for the Flight Control System of a certain type civil aircraft. First, FAA Aviation Rulemaking Advisory Committee （ARAC） explanation and suggested evaluation approaches for CCAR25.671（d） are expatiated; Second, effects of all engines fail on a certain type civil aircraft and its flight control system are analyzed; Third, the compliance validation approaches, fault simulated methods, test procedures and the acceptable criterions for MOC6 and MOC8 methods are detail introduced separately. Methods presented herein provide a valid approach for justifying that the design of the Flight Control System of civil aircraft is compliant with CCAR25.671 （d）.
