Innovative Optimization Concept for Point Merge Structure at Leipzig/Halle Airport to be Presented at ATRD Symposium in Prague

June 2025 | Airport Planning

Over the last year, GfL has researched a possible re-implementation of a Point Merge approach procedure at Leipzig/Halle airport on behalf of the Saxon ministry of economy and close cooperation with the airport operator MDF AG, the ANSP DFS and the main airspace user DHL/EAT. To reduce both fuel burn / CO2 emissions and noise exposure, numeric optimization has been employed to lay out the best possible Point Merge System (PMS). The innovative method that combines a fast-time traffic simulation, a noise calculation, and a numerical optimization process, will be presented on 24th of June at the US-Europe Air Transportation Research & Development Symposium in Prague. Papers and presentation slides will later be available on the conference website.
