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

DPI: Departure Planning Information (new-TTOT)

17. INCENTIVE TOBT Procedure Rules: Airline ATC Organisation
Slotted aircraft get a higher priority than non slotted aircraft
TOBT-H transmitted between 60’ and 40’ before estimated take off time (ETOT) or
40’ and 20’ before estimated off block time (EOBT)
Without slot, TOBT-H is used to enter the flight into the pre departure sequence
Without TOBT-H, flight will be treated as today
Issue of a new TOBT-H results in a new TWR sequencing (S, R or D)
At TOBT-S +2’, no taxi or no start-up request or no actual off block time (AOBT)
the flight will be re-sequenced at the end of the queue
ATC
The sequenced TOBT (S, R or D) will follow within 5’ after TOBT-H
TWR sends a TOBT-X in case of re-sequencing due to the airport conditions
TWR evaluates a standard taxi out period according to stand position and the period of the day
TWR calculates a HOPS time

18. Airport CDM CFMU WP3 : New Messages FUM, DPIs

19. 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.

20. 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 .

21. DPI : Departure Planning Information
TOT
CFMU : - use Take Off Time instead of ( Off Block + Taxi Time )
CDM Airport : - identified like a CFMU partner : CDM-A
DPI : - are Informative Messages from CDM-A to CFMU
. do not re-compute the SLOT
. system to system message
. triggered by system events
. sent automatically
DPI DATA : Take Off Time belongs to CDM-A
The consistency between FPL / DPI is the responsibility of the CDM-A
DPI : For all flights (regulated or not)
TTOT : Target Take-Off Time SXOP : Standard Taxi-Out Period

26. 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.

27. Airport CDM Malpensa WP2 : Proposals

28. 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,

29. 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.

30. Post Operations Analysis
Objectives (WP 4 preparation)
Definition of CDM KPIs (at the Airport Level) acknowledged by all airport partners,

31. 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.

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

33. 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’
