  2. Improved TOT Prediction – normal operations TOT accuracy 4min TOT accuracy=8.4 Improvement: 23% Improvement: 13% TOT accuracy=9.7 60min before take-off 30min before take-off

  3. Improved TOT Prediction – adverse conditions TOT accuracy 5min Improvement: 54% TOT accuracy=23.6 Improvement: 29% TOT accuracy=33.3 90 min before take-off 30min before take-off EGLL 10/07/2012

  4. Improved TOT predictions lead to: • For the network/NMOC: • Improved traffic count predictions • Better use of available capacity • Improved adjustment of CTOT to requested TOT • For AOs: • Better suitable CTOT • Improved Estimated Landing Time prediction • For Airports: • More accurate estimated landing times for inbound flights • For ANSPs: • More accurate traffic count predictions via NMOC data distribution services ©2011 The European Organisation for the Safety of Air Navigation (EUROCONTROL)

  6. Other Benefits of A-CDM… • For the Network: • Better use of available capacity • Improved adherence to ATFM Slots • For AOs: • Better adjustment of CTOT to local constraints • Improved visibility of flights at the outstation • Assistance to updating flight plans • Enabler for improved flight and fleet planning • Reduced risk of suspension by Flight Activation Monitoring • Allow to delay and advance the TOBT • No more DLA required if flight is delayed by ATC (ground) • CTOT freezing from Actual Off-block onwards • Improved management of adverse conditions ©2011 The European Organisation for the Safety of Air Navigation (EUROCONTROL)
