A Novel Methodology for Optimizing Instrument Approach Procedures

This work outlines the fundamental ideas employed to address the problem of instrument approach procedure (IAP) design using combinatorial optimization methods. Our approach takes advantage of the possibilities offered by the PBN (Performance-Based Navigation) concept, which includes structured, globally harmonized flight procedures backed by standardized performance requirements. We present a new criterion for IAP optimization, focusing on the flight crew’s perspective of procedure complexity. Within this novel methodology, we have proposed a mathematical model that includes all of the essential components for generating an IAP in accordance with the specified design criteria related to the LPV (Localizer Performance with Vertical guidance) procedure. Furthermore, we have incorporated the capability to generate procedures for different landing threshold positions into the model, thereby extending the range of potential solutions. We used several generic scenarios to validate the established metaheuristic algorithm’s ability to autonomously and automatically provide solutions that satisfy the specified operational requirements.
