Sequencing Efficiency
Aircraft are managed by the expected arrival times. The method used is called sequencing.
Green Approaches see aircraft fly idle thrust approaches at higher altitudes. This means less noise and fewer complaints.
Brisbane has shown that it is immediately possible to start with Green Approaches. Aircraft on such approaches can be integrated with conventional aircraft on the same runway.
Green Approaches are safer and more efficient.
For Green Approaches, aircraft are flying low noise flight paths, with great accuracy and predictability. Aircraft can follow the flight paths into Brisbane with an accuracy of half a wingspan.
Aircraft are managed from further out by slowing the aircraft down as they approach the airport. Traditionally aircraft were put into holding patterns.
