Fully integrated and throughput-optimised sequence of arrivals and departures for the same runway (or for dependent runways) is set up by an algorithm considering minimum separations. The sequence is characterised by high planning stability and all controllers working towards establishing the plan. Thus, in addition to arrival metering and pre-departure sequencing, controllers will follow Target Take Off Time (TTOT) and the Target Landing Time (TLDT) as closely as possible. Feeder controllers will provide the required gaps in the arrival sequence to allow for the respective departure flights
