Flow Management

Airport Collaborative Decision Making (A-CDM)

Definitions

  • Estimated Off-Block Time (EOBT) - General estimate as to when an aircraft will be ready to start-up/push-back. Do note that the TOBT is more accurate as it may be updated, whereas the EOBT is static.
  • Target Off-Block Time (EOBT) - The time that aircraft operators estimate that they will be ready, all doors closed, boarding bridge removed, push-back vehicle available and ready to start-up/push-back immediately upon reception of clearance from ATC.
  • Target Start-Up Time (TSAT) - Calculated time at which start-up clearance can be expected. TSAT includes all parameters such as calculated take off time (CTOT), variable taxiing time etc.

Target Start-Up Time (TSAT)

After an aircraft gives confirmation of being ready for pushback, DEL will instruct pilots to monitor GMC at TSAT +/- 2 MIN and standby for further ATC instructions.

Important

It is vital that only DEL, or FMP/Planner if online, should click on the button outlined in Figure 1.3 as it is their responsibility to manage. All other controllers should use the .cdm slave [ICAO] command instead.

Arrival Manager (AMAN)

The Arrival Manager is a tactical resource controllers/flow managers may utilise to help form a sequence during times of increased arrivals.

Controllers are always in charge

This tool exists to support controllers/planners, thus it shall not be relied on fully.
