Preliminary Assessment Organisational Issue : Cross Organisations Teams and Decision Making Optimisation of Airport Resources Today: “Individual Company View” Airport Airlines ATC Handling agents Tomorrow: “Extended Enterprise View” Airport Airlines ATC Handling agents Individual optimisation, often not considering the effect on other stakeholders All companies aware of cross organisational interfaces Little or no cross-organisational communication with respect to decisions with cross- organisational impact All companies balancing their economic targets in an integrated way Interfacing with other partners (e.g. handlers, AOC, etc. Non-optimal Result Cross-organisational teams and decision making Cross-organisational key performance indicators

CDM - Objectives

Airport CDM BARCELONA WP3 : Information System

Mission Link 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 Awareness Support the local collaborative decision-making Facilitate the implementation of collaborative procedures

Airport CDM CFMU WP3 : New Messages FUM, DPIs

Air Traffic Flow and Capacity Management Specify exchange between CFMU and Airport CDM, Specify exchange in the context of: . information on the inbound flights : LDT . information on the outbound flights : TOT . disruptions . FPL - Airport Schedule consistency checking, Define the timing, trigger and content of the messages, Evaluate the benefits for CFMU, Airports and AOs.

FUM : Flight Update Message LDT The FUM is sent to advise Airport CDM and APP about the modification of ETA and to supply the APP with the new estimated time and FL over the IAF of the STAR or over the last point of the Route. AND With the DPI3 and DPI2 messages issued to the CFMU from the outstation the FUM message may be sent to advise Airport CDM and APP about the modification of ETA before the Off Block Time .

Airport CDM VANTAA & ARLANDA WP2 : Proposals

AIRPORT CDM INFORMATION SYSTEM Taxi Period Study (in & out) Collaborative Procedures . De-icing . Pre-Departure Sequence Post Operation Analysis based on CDM KPIs

TAAM Arlanda Airport Modelling Taxi Time Simulation

TAXI -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.

Airport CDM Malpensa WP2 : Proposals

CDM Project Proposals for Change Item Definition Improve 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,

CDM Project Proposals for Change Item Definition Improve 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.

Post 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 quality On a regular basis, analysis of the results in a meeting with representatives of all airport partners.

Post Operations Analysis Expected Benefits Standard 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.

Airport KPIs Estimates Measurements done at different milestones Comparison prior to CDM and with CDM Evaluate Turn around time Decrease S&G changes Evaluate Security Check-in Period Measure occupancy duration AOBT - AIBT Measure estimates occupancy in /out block EIBT/EOBT and EIBT/ESDT Measure the number of changes in the S&G allocation Measure and compare period between EOBT-EIBT and ESDT-EIBT Measure ESCP (Start check-in time and End check-in time) Compare ESCP and ASCP Improve Punctuality Passengers Information Change ETD information by TOBT information (no ATFM delay) Give ESCP (Start check-in time and End check-in time) information Optimise use of Available Capacity ( S&G, Checking pax and bax ) Optimize S&G occupancy Optimize check-in operations Count flights request to the TWR with earlier off block time (for waiting bay or taxi way) Count flights with earlier off block time (accepted by the TWR) Count number of ESCP end after the start boarding time Increase Efficiency Adapt S&G allocation to : - Airline preferences - Handlers preferences Measure satisfaction rate: airline, handlers Improve Bag service Count number of luggage out of allowed volume and/or weight Count number of delayed flight with handbag problem after the boarding Compare the number of Bag containers and the number of destinations

Airport KPIs Reduce Environmental Nuisance Reduce noise on ground Reduce emission from engines Measure taxi-in and taxi-out periods by runways configuration Measure waiting period by flight at the holding point Improve Safety Reduce Movements Number (trucks, bus,…) Measure number of last S&G changes due to overlapping between arrival and departure after ESDT -20’
