Capacity & delays
What to expect in terms of capacity improvements and delays in Bordeaux & Brest ACCs ?
Understanding the different transitioning phases at Bordeaux Area Control Centre :
As a foreword to any major Air Traffic Management system implementation, capacities have to be reduced to allow each air traffic controller to safely take control, in real time operations, of all the new capabilities available. DSNA therefore defines a consistent and balanced capacity offer aiming at alleviating the constraints on traffic.
THE TRAINING PHASE
280 air traffic controllers of Bordeaux ACC to train while the ops room still needs to be running smoothly. Vacation time are spread out the best compatible way to ensure the maximum number of control sectors to be opened according to EEE training courses’ constraints. In addition, to minimise the impacts on Aircraft Operators, training is suspended in the Summer and during week-ends to recover optimal capacity at peak periods.
THE ADJUSTMENT PHASE : TRUSTING THE SYSTEM WHILE MITIGATING THE DOWNSIDES ON TRAFFIC
As the adjustment phase constitutes the solid base for a successful commissioning, the capacity offer has to be reduced to allow confidence in the system and safe working patterns to be achieved by controllers, in real time situation. To minimise the downsides on traffic and particularly meet the important increase of overflights on the south west axis (major traffic flows from Northern Europe to Spain, Portugal and the Canary Islands), providing airlines with the best possible and consistent capacity offer is key to the process. The cut downs are thus decided considering each control sector’s specificities and the type of traffic it has been designed for.
How to minimize the impact of the capacity cut down ?
- Winter period has been chosen for implementation. During winter, the traffic demand rarely reaches the capacity offer. It usually allows ATCOs’ ongoing training courses to be organised at that time of the year as the ops room configuration can be more easily adapted. For EEE all manpower will be made available so that the initial reduction of all sectors’ capacity will not dramatically impact aircraft operators. However, most of the delays that might affect the flights crossing the Bordeaux airspace will certainly be caused by the new system adjustment and recovery phases.
- Maximum sector configurations will be ensured to provide maximum capacity offer and to adjust to the traffic demand.
THE RECOVERY & CONSOLIDATION PHASE : WORKING TOWARDS LASTING CAPACITY OFFER
After taking control of the new system, front line operators reach a reliable comfort zone and capacity improvements are studied, meeting airlines operators’ expectations
