Aena Zilina, Zilina, How to improve Airport Efficiency by means of CDM: LEONARDO Linking Existing ON ground, ARrival and Departure Operations Patricia Pina Maria Mas

Zilina, Contents  Scope & Approach  The System  Trials results  Arrival predictability  Off-Block predictability  Departure predictability  CFMU slot predictability  Conclusions

Zilina, Scope of LEONARDO  Problem: Lack of efficiency  Individual optimisation of airport processes  Existing information not available for all actors  Solution: Integrate existing planning tools for:  Arrival management  Departure management  Ground operations management INTEGRATION LAYER AIRLINES AIRPORT OPERATIONS ARRIVAL PROCESS FLOW CONTROL DEPARTURE PROCESS GMC GATE ALLOCATION

Zilina, LEONARDO Approach  3 different levels of integration  Information sharing  Cooperation - Improvements in planning estimates  Negotiation among actors  2 different validation techniques  Shadow mode trials  Real time simulations  2 different testing airports  Barajas  Charles de Gaulle

Zilina, Off-block predictability  Better In-block time prediction, thus better TOBT prediction  Improvement of TOBT Predictability due to the info shared by the airlines with the CDM system.  24 % error decrease when considering delay messages from the airline

Zilina, Take-Off predictability  Improvement of ETOT Predictability due to a better TOBT and taxiing time.  DMAN calculates the optimum departure sequence: MTOT ERROR AS A FUNCTION OF % EGOP

Zilina, Probability of slot alarm to be reliable  Statistical simulation of the Alarm prediction based on taxiing time distribution  Measurement of discrepancies between simulated alarms and slot compliance

Zilina, LEONARDO Results In-block Predictability  CDM has positive effect on efficiency, further improvement possible Off-block Predictability Up to 80% improvementUp to 50% improvement Take-off Predictability Up to 50% improvement

Zilina, Leonardo Conclusion  CDM makes sense  Experiments in the three sites confirm us the same tendency:  Improvement in predictability of operations  Better management of existing resources (stands, handling equipment, runway)  Improvement of decision-making processes  The R&D results are available and stakeholders should use them:

Zilina, Future Work  Implement collaborative processes with CFMU  Inclusion of actors priorities and negotiation  Creation of a network: integrate tools at origin and destination airports CFMU

Zilina, THANK YOU FOR YOUR ATTENTION
