Airport - Collaborative Decision Making

The future is certain, the future is shared, the future is accurate, the future is now

A-CDM Winter Operations

As we head into the Winter period A-CDM operations will be changing to accommodate De-icing. Training is underway across the airport to prepare for this.

We all have plans to work more efficiently, increase punctuality and improve our environmental performance. We will achieve a better overall result together. The collaborative approach that A-CDM represents achieves more and is less costly based on common processes, data and targets. Let's work smarter, not harder!

Key focus area

Accurate departure time estimates are critical so we can use our assets more efficiently and get ready for the A-CDM Trials. At twenty minutes before departure we use your Target Off-Blocks Time (TOBT) to create a 'virtual place' for the aircraft on our busy runway and in-turn, during trials, give you sight of an expected Target Start Approval Time (TSAT).

Ground operations

Target Off-Blocks Time (TOBT) must be updated to an accuracy of +/- 5 minutes. If your TOBT is changing please take a minute to think through the reason the time is changing and decide on a new time that is realistic. Late, small and repeated incremental changes are to be avoided as this creeping delay creates a phantom requirement for a runway place. Remember your pilot can still call up within +/- 5 minutes of TOBT so there is a ten minute window available.

Flight operations

Estimated Off-Blocks Time (EOBT) must be aligned to within +/-10 minutes of the TOBT

Crew

Pilots should call Delivery at TOBT +/-5 minutes
