To be an EnvironmentTo be an Environment--Friendly UserFriendly UserTo be the Good Friend of all UsersTo be the Good Friend of all Users

IMPROVE SAFETY OF OPERATIONSPromote an airworthiness approach to collision avoidance (no longer based on "see & avoid")Promote development of position reporting system to allow all users to become "cooperative"Promote safe communication means no longer based on voice messages

Voice used only for extraordinary purposes (NGATS ConOps)

OPERATE ABOVE AIRLINER TRAFFIC (Ecological cruise)In Climbing Cruise mode (3 to 5 % fuel saving)

OPERATE AT HUB AIRPORT WITHOUT EFFECTS ON AIRLINE OPERATIONS4D Wake vortex free approaches to allow runway operations at full capacity

REDUCE NOISE NUISANCES TO AIRPORT RESIDENTSDevelop real CDA (Continuous Descent Approach) and "steep & curved" approaches

SESAR Concept of OperationsSESAR Concept of Operations


INEFFICIENT ATM NETWORK

Future ATM Concept of OperationsFuture ATM Concept of Operations

EFFICIENT ATM NETWORK

TRAJECTORY MANAGEMENT

Collaborative and iterative development of the

4D Business trajectory fully owned by the airspace user and

at all times maintained to ensure the best business

outcome for the airspace user.

CONFLICT MANAGEMENT

Management of conflicts based on the layers and concepts outlined in the ICAO Global ATM Operational Concept using methods that ensure minimum disruption to the

Business trajectory.

4D Trajectory4D Trajectory

4D TRAJECTORY MUST PROVIDE FLEXIBILITYYou are deluding yourself if you think that aircraft can subscribe to a fixed schedule

Aircraft operations correspond to a long succession of incidents which delay operationsPassengers don’t want to wait long time before departures

Business Aircraft passengers want to go when they are ready

4D TRAJECTORY MUST NOT MEANTime constraint at each waypoint, but a RTA constraint (and only for HUB runway operation)

THE USE OF 4D TRAJECTORY (Relative Time Concept)Accurate prediction mode : to identify and to develop "Margins"Real operation mode : to eliminate most of traffic conflicts (flight level change)

RTA : Required Time of Arrival

Challenges & ConcernsChallenges & Concernsfor Business Aviationfor Business Aviation


Challenges for Business AviationChallenges for Business Aviation

THE BUSINESS TRAJECTORYWho will develop the Business Trajectory, (FOC, but be possible without FOC)How the “Shared & Reference Business Trajectory” will be established and finalized ?

Priority rules between users will have to be finalized and evaluated in real conditions ?In Flight “Reference Business Trajectory” will be updated by the pilot

Be sure that it is compatible with pilot workloadWhat will be the cost of these services ? (FOC, CDM, SWIM)

ROLE OF FOC/AOCEssential in the establishment and in the negotiation of Business TrajectoriesFOC will not be a problem for Business Aviation companies (they have it)FOC role might be a problem for "Small companies" (cost impact)

ANSP : Air Navigation Service ProviderAOC : Airline Operations Center (SESAR)FOC : Flight Operations Center (NGATS)RBT : Reference Business TrajectorySWIM : System Wide Information System


Concerns Concerns

4D TRAJECTORY & ASASNo other solutions (SESAR & NGATS common concept)The devil is in the details

Business Aviation community must be an active player of the future ATM developmentNeed for technological developments :

- communication domains (data link must become the primary means of communication)- surveillance (ADS-B, ASAS, Position reporting system)

Full cooperation between USA (NGATS) & Europe (SESAR) is a mustCommon solutions must be the rule

UDPP (User Driven Prioritization Process)How equity between all users will be guarantied ?

NGATS : Next Generation Air Transportation System (USA)ADS-B : Automatic Depenpendance System BroadcastASAS : Airborne Separation Assistance System


Today & TomorrowToday & Tomorrow

● SESAR OBJECTIVEReduction of ATM cost by 50%

● CONSEQUENCES FOR BUSINESS AIRCRAFT OPERATORSInvestments in avionics systems : 4D, ASAS, Nav, Com, SurveillanceInvestments in the services : Development of FOC Investments in pilot training : New roles for pilots
