S-AF2.1 — DMAN synchronised with Predeparture sequencing

Departure management synchronised with pre-departure sequencing is a means to improve departure flows at one or more airports by calculating the Target Take Off Time (TTOT) and Target Start Approval Time (TSAT) for each flight, taking multiple constraints and preferences into account. Pre-departure management consists of metering the departure flow to a runway by managing Off-block-Times (via Start-up-Times) which take account of the available runway capacity. In combination with Airport - Collaborative Decision Making (A-CDM), Pre- departure management reduces taxi times, increases Air Traffic Flow Management-Slot (ATFM-Slot) adherence and predictability of departure times. Departure management aims at maximising traffic flow on the runway by setting up a sequence with minimum optimised separations.
Operational stakeholders involved in A-CDM shall jointly establish pre-departure sequences, taking into account agreed principles to be applied for specific reasons (such as runway holding time, slot adherence, departure routes, airspace user preferences, night curfew, evacuation of stand/gate for arriving aircraft, adverse conditions including de-icing, actual taxi/runway capacity, current constraints, etc.).

Deployment Target Date


System Requirements

- Departure Management (DMAN) and A-CDM systems shall be integrated and shall support optimised pre-departure sequencing with information management systems for airspace users (Target Off Block Time (TOBT) feeding) and airport (contextual data feeding).
- DMAN systems shall elaborate a collaborative sequence and provide both TSAT and TTOT. TSAT and TTOT shall take into account variable taxi times and shall be updated according to the actual aircraft take-off; DMAN systems shall provide the air traffic controller with the list of TSAT and TTOT for the aircraft metering.
