8MissionLink airport slot with flight plan data and relevant information of ARRIVING and DEPARTING flights,Link airport operations, aircraft operators and ATC systems,Provide one set of data describing the status and partners intentions on a given flight,Serve as base for information sharing between partners,Useful for collaborative procedures (pre-departure sequence).Expected Benefits :Common Situation AwarenessSupport the local collaborative decision-makingFacilitate the implementation of collaborative procedures

FPL - Airport Schedule consistency checking,Define the timing, trigger and content of the messages,Evaluate the benefits for CFMU, Airports and AOs.
20FUM : Flight Update Message LDTThe FUM is sent to advise Airport CDM and APP about the modification of ETA andto supply the APP with the new estimated time and FL over the IAF of the STAR orover the last point of the Route.ANDWith the DPI3 and DPI2 messages issued to the CFMU from the outstation the FUMmessage may be sent to advise Airport CDM and APP about the modification of ETAbefore the Off Block Time .

26TAXI -OUT PERIOD STUDY - RATIONALE In the US, Taxi delay results in the largest direct operating costs of all delays,The average taxi-out delay per flight is approximately twice the airborne delay (ref. ATA study, 2000),Even if aircraft burn fuel 5 times faster when airborne, crew and equipment costs make the spend rate about 2/3 (taxiing aircraft versus airborne aircraft),The cost of taxi out delays in the US exceeds 1 billion USD per year,On average, Taxi out delays is 3 times larger than taxi-in delays,Non-Flexible Taxi-out Periods lead to C/ETOT uncertainty and ATC overdeliveries.
28CDM Project Proposals for Change Item DefinitionImprove the Information System according to the CDM requirements (milestones approach, Target Off Block Time...),Define a CDM Service Level Agreement Concept for data exchange/applications,Identify CDM processes,
29CDM Project Proposals for Change Item DefinitionImprove the Collaboration according to the CDM requirements :Flexible Taxi Time,Pre-departure sequence,ATFM DPI messages transmission,Airlines’ priorities,Disruption recovery…Perform a light Cost Benefit Analysis for each implementation.
30Post Operations Analysis Objectives (WP 4 preparation)Definition of CDM KPIs (at the Airport Level) acknowledged by all airport partners,Retrieve information from existing systems,Analysis and Compilation into understandable documents,Maintain the data qualityOn a regular basis, analysis of the results in a meeting with representatives of all airport partners.
31Post Operations Analysis Expected BenefitsStandard and common basis for all aiport partners,Better assessment of operations efficiency that would help in discussing possible improvements,Better forecasts, identification and quantification of problems,Possibility to have a better view on financial impacts.
