What is the difference between Dynamic DCB and Complexity Management?
The actions of Dynamic DCB and Complexity Management both react to traffic loading prior to its entry into a sector. Dynamic DCB can have impacts at local and network levels. As the look-ahead for decisions is up to 2 hours, these will be based on less-certain data as a proportion of aircraft involved may be on the ground at the time of forecast. Complexity Management decisions apply actions at ATC local-level based on forecasts of aircraft already in flight, which therefore use more precise data, with look-ahead of around 40 minutes prior to sector-entry and could result in minor adjustments to flight profiles. Dynamic DCB solutions will be more adapted to solve traffic demand/capacity imbalances. Complexity Management is only expected to be necessary in specific regions of very high traffic density and is therefore an optional layer of the ATM process to be deployed only when fully justified. Unless deployment of Complexity Management can be justified Dynamic DCB alone will ensure ac
