Concept Outline
�What is ABCD?
To link individual flight plans related to the same aircraft by using the aircraft registration in order to:
� Monitor delay propagation all along the day of operations
� Propose an update of the departure time in case of inconsistency with actual operations.
Concept
1. Provide a better picture of operations in real time
� Improve flight predictability
2. Detect and notify earlier reactionary delays
� Optimize the slot allocation process
� Decrease the ATFM delay
� Mitigate the delay propagation on subsequent flights

First findings
� Statistical analysis from the CFMU archive
data
� Late notification of delays by airlines
� The earlier an airline notifies a delay, the
smaller the imposed ATFM delay
� ABCD would decrease ATFM delay10

Lost ATFM Slots Analysis (CFMU level)
� Earlier notification of delay
messages to the CFMU
Lower number of
lost ATFM slots
Lower overall ATFM delayBetter use of the
available capacity
Better efficiency of the
ATFM service
• An ABCD-like tool will contribute to bring such benefits

Cost Benefit Analysis (airline level)
� Benefits resulting from the reduction in ATFM delay due to ABCD use by the airline
� Conservative assumptions
� Method: ATFM fast-time simulations
� Gains in ATFM delay are translated into financial gains:
� Aircraft model cost based on the marginal cost of one minute of ground delay spend at gate
� Limited investment costs:
� Acquisition cost (development of the software)
� Installation cost (ABCD operating with a standard computer)
� Maintenance
� Training cost (very low)
� Human resource cost (null)
Benefits Costs

Key aspects of prototype development
Repository that contains all the necessary information for the correct operation of ABCD
Core of the ABCD prototype
Set of algorithms which detect the propagation of reactionary delays through consecutive flights of the same aircraft
Main functions
• To calculate EPOBT (Earliest Possible
Off Block Time) for each scheduled flight using available information from the previous flights
• To perform new EOBT proposals
depending on the tolerance windows and the established stability criteria

� Proposition: Provide ABCD with access to new CFMU services (e.g. NOP portal applications, CHMI/CIAO, Data Distribution Service / ETFMS Flight Data)
� Objective: Improve the quality of ABCD input data, hence the relevance of EOBT proposals
� What-if Mode
� Proposition: Upgrade ABCD to consider CFMU proposals in addition to “effective” messages (e.g. slot proposal / rerouting proposal / slot swapping opportunities)
� Objective: Provide support to analyse the impact of proposals on the next flights
