Following more precise arrival routes helps aircraft to reduce track miles and minimise noise over built up areas. Thanks to the use of GNSS (such as Galileo), aircraft can fly RNP with accuracies of 0.3 nm or 0.1 nm, enabling airlines to fly more efficient routes and follow more flexible approach paths. Aircraft can use different alignment points to optimise procedures in terms of fuel consumption or noise abatement. By using advanced curved approach operations in the terminal area, aircraft benefit from shorter flight trajectories, increased efficiency and predictability, while reducing workload for flight crews and controllers.

This candidate solution aims to validate a system support tool for ATC, to enable mixing advanced curved approach operation, combined with legacy straight in approach operation.
