To address the prominent issues of noise pollution and fuel consumption during aircraft go-around phases， this paper selects the dual-runway independent parallel instrument approach pattern at Tianjin Binhai International Airport as the research scenario. By developing a complex aircraft sequencing model that incorporates speed variations and controller coordination factors， and by integrating existing performance-based navigation （PBN） procedures with aircraft performance parameters， an optimization analysis is conducted. First， missed approach parameters are redefined based on previously optimized PBN approach procedures. Second， an improved aircraft reinjection system（ARS） intelligent method is employed to refine the existing missed approach procedure， planning three-dimensional Dubins paths as the new missed approach procedure. Finally， a multidimensional evaluation model encompassing noise， fuel consumption， and safety separation is constructed to validate the optimization effectiveness of the proposed procedures. The results demonstrate that the new procedure maximizes noise reduction and fuel savings during the missed approach phase while ensuring flight safety， thereby improving overall operational efficiency. Comparisons of noise impact zones， fuel consumption， operational distance， and time before and after optimization show significant improvements with the optimized procedures meeting all operational safety standards.
