Using curved approach procedures, based on geometric altitude (GNSS-based), allow airlines to fly efficient routes in the terminal area, to conduct stable and predictable continuous descent operations independent of temperature (Improved productivity among flight crew and ATC). This will contribute to increased efficiency, predictability and lowered environmental impact.

This candidate solution aims to validate the use of GNSS-geometric guidance after the initial approach fix, which offers opportunities for optimised three-dimensional approach operations with enhanced aircraft energy management in order to make the transition to the final approach phase easier in any weather conditions, which might affect today’s barometric vertical navigation. It requires developing and validating a concept that enables controllers to ensure that safe vertical separation is maintained between all traffic, whether they are using geometric or barometric vertical navigation. 

This solution was formerly part of PJ.02-11-W1.
