Paired approach(PA) mode is an efficient approach mode that operates on Closely Spaced Parallel Runways(CSPRs) and aims to improve the approach efficiency under Instrument Meteorological Conditions(IMC). The complete process of this mode is rarely elaborated in China. This paper mainly analyzes the opreational process and definite running requirements of the Paired Approach procedure on CSPRs; Combined with the present domestic CSPRs operation of the airport and PA model research and application status of the urgency of the proposed PA model introduced into China, and the research direction in the future.
