OSYRIS Pre-Departure Sequencer
PDS automatically calculates Estimated Take-off Times (ETOT) for each outbound flight, leading to an initial departure sequence, representing the earliest possible take-off time without any capacity constraints at the runway. Calculations are based on Target Off-Block Times (TOBT) and Variable Taxi Times (VTT).
The continuous take-off sequencing process results in Target Take-off Times (TTOTs) and Target Start-up Approval Times (TSATs) which can be shared among all stakeholders according to local requirements. Airports and ground handling companies are supported in efficiently allocating their available resources
