Deployment Scenario Title

Advanced geometric GNSS-based procedures in TMAs

Deployment Scenario Description Advanced geometric GNSS-based procedures in TMAs: this solution validates the use of GNSS geometric guidance from the initial approach fix or earlier, facilitating a wider variety of curved approaches to a single runway. It also addresses curved departure routes that turn shortly after take-off in order to avoid noise-sensitive areas, approach routes or missed approach routes. For airports where there is a dependency between departure and arrival runways, flexible and customised departure routes may be possible, thus allowing for an increase in capacity.
