10 Contract of Objective Operational contract associated to a flight : punctuality at destination airport integrated efficiency: linking planning and execution common objectives: operational continuity linking actors marked out by target windows Say what you do Do what you say 1 flight = 1 CoO On ground Taxiing On Flight Taxiing On ground Airport TWR ANSP1 ANSP2 ANSP3 TWR Airport (Approach) Off-Block Time Take off Landing In-Block Time Control Unit Control Unit Control Unit Optimisation DMAN Optimisation AMAN 10

11 Target windows 4D intervals to constrain traffic in order to ensure planning is respected Downstream issues reflected at actor level: Efficiency Destination punctuality Technical capability (flight envelope,...) Congested en-route area (bottleneck) Resilience Residual uncertainty (disruptions management) open room of adaptation to operation to ensure resilience to disruptions Limits chain reactions 11

12 Operational Plan Strategic level Macroscopic approach rather than a temporal reference Defines collaboration between actors allowing them to coordinate (i.e. agreed interfaces) called Operational Agreement Operational Agreement: traffic resulting from the expressed & agreed constraints of involved actors (initial source of contracts of objectives) Collaborative & transparent mechanism involving all actors Airlines, Airports & ANSPs (civil & military providers) Conciliate demand with scarce resources Demand Resources Agreed Trade-off Operational Agreement Refinement & enhancement process Iterative evaluation of demand versus resources Adaptive granularity description regarding disruptions 12

13 Operational Plan Airports Airport capacity Rotations AirLines OA r1 Actor preparation phase Actor publication phase time 13

14 Operational Plan Considering first, highly constrained resources : Runways Conciliate initial demand & airport capacity Large granularity Initial demand Rotations described as successive airborne segments linked by airport operations on ground Airborne segment defined by a city pair & an average flight duration On ground segment defined by an average «airport operation» time Airport capacity An average number of landing & taking off aircraft for a given time frame (mitigate by on ground operations) Come to a first Operational Agreement (OAr1) 14

16 Operational Plan Integrating ANSPs constraints & resources Refine Operational Agreement by inserting control capacity Medium granularity Conciliate control resources to demand, build first strategic traffic Refine airport capacity by taking into account control constraints (reduce time frame window size) Enhance departure & arrival time windows for initial demand Come to the second Operational Agreement (OAr2) Anticipation of disruptions (survey process) Integrate disruption forecast to align iteratively strategic traffic & interfaces Come to the final Operational Agreement (OAf) 16

26 Working methods innovation & legal issues Change in working methods, airspace structure... => impact on operators juridical responsibilities The task sharing between: Human/Human Human/Machine Certification Ground/Board Juridical implications : - responsibilities? - delegations? For the project: Completing multidisciplinary team by juridical approach Leading some choice of design For the Law: Avoiding legal deadlock Technical evolution => Regulation evolution 26

27 A concrete application : the dual airspace Intercontinental Highways States sovereignty (International Law) Route Charges (Public Law, Aviation Law) ATCOs status (International, Public, Civil Law and why not an ATM Law?) Design issues : Should the 2 sub-systems visualize the other s traffic? yes = possibility to be responsible of these aircraft no = no possible responsibility French Law Article du code pénal Establish clear connection between the 2 sub-systems To avoid responsibilities problems To create confidence in the juridical system for ATCOs Conflict between Safety and Responsibility 27
