According to the requirements of"Rules for Operational Qualification and Certification of Public Air Transport Carriers of Large Airplanes"(CCAR-121-R8)and Advisory Circular called"Operation of Plateau Air-ports",the route adaptability analysis of plateau routes mainly includes drift-down analysis and oxygen supply analy-sis.In this paper,drift-down analysis and oxygen supply analysis for SR-VIKUP flight segment are carried out,which is a typical case of long distance,high altitude,few alternative airports,and high frequency of use operated by Boeing 787-9 aircraft.This paper firstly analyzes the regulatory requirements and influencing factors of the drift-down procedures and cabin depressurization procedures for plateau routes,and determined the calculation parame-ters.Secondly,it calculates the route performance after one engine failure,followed by obstacle clearance analysis based on the feature that the large pulsed oxygen system of the Boeing 787-9 model can flexibly configure the de-scent profile according to the terrain,in combination with the minimum safe altitude of the flight segment.Finally,according to the temporary re-routing needs in operation,the emergency procedures for drift-down after the failure of one engine and the emergency procedures for cabin depressurization are optimized.This study has solved a major difficulty in operation control in this area,and is of positive significance to the operation of other impulse oxygen system models and similar plateau routes.
