(27)Regarding NADP procedures specifically, the Netherlands claims that between 1 January 2023 and 28 July 2024, more than 95 % of flights already followed the NADP-2 procedure. Regarding operations that do not yet use this procedure, the Netherlands claims that it is not legally enforceable, and some pilots apply a different procedure as required by the airline they fly for. Regarding PBN procedures, these allow aircraft to fly very precise lateral flight paths and improved climb and descent profiles, thus contributing to noise reduction. Commission Implementing Regulation (EU) 2018/1048note on PBN requires that providers of air traffic management/air navigation services ensure a smooth and safe transition to the provision of their services using performance-based navigation services and publish PBN procedures. LVNL has published several PBN procedures including procedures with the Radius to Fix (RF) feature that allows aircraft to navigate more accurately between the residential areas enabling to reduce the spread in flown tracks in between built-up areas.
