PRE-DEPARTURE SEQUENCER (PDS)
Orthogon Pre-Departure Sequencer (PDS) reduces taxi times and enhances sequence and departure time predictability.
The Orthogon PDS provides all capabilities required for Airport-Collaborative Decision Making (A-CDM). Optimising push back times allows for reduced taxi times, enhanced sequence and departure time predictability, and reduced queues.
Calculating estimated Take-off Times (ETOT) for each outbound flight, leads 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
