The solution is composed of a point merge system coupled with an arrival management tool that provides sequencing support based on trajectory prediction. Rather than entering holding patterns, aircraft in the extended terminal area enter performancebased navigation (PBN) routes referred to as point merge legs, where they fly briefly in a level-off lateral holding situation where the distance to the merge point remains constant. When the spacing with the preceding aircraft is attained, the controller will instruct the next aircraft on the leg to turn direct to the merge point. Unlike conventional traffic streams which are individually vectored, the turn the aircraft needs to perform in the point merge leg is always the same, which simplifies the controller’s tasks. The flight crew’s task is also simplified by the use of this standardised manoeuvre which is predictable and repeatable.
