Implementation plan 

• CFMU10.0 

- parsing and processing of FUM/DPI info 

- update profile with CDM info: taxi-time/SID 

- analyse data, evaluate (simulations) 

- prototype CASA update with DPI info 

- feed back to CHMI (CIAO, CITO, CIFLO) 

• Transfer into operation: 

CFMU10 CFMU10.0, 0 CFMU11 CFMU11.0 0 and beyond

FUM: Flight Update Message 

The FUM is sent to advise Airport CDM about the modification of ELDT 

and with the new estimated time and FL over the last point of the Route.

E-DPI DPI : Estimated Departure planning information 

AT EOBT - 3hours : E-DPI 

Objective j of the E-DPI message g 

- Compliance of EOBT and Airport schedule (SOBT) 

- Provide a first Taxi-time and SID for ATFM Slot calculation 

⇒Incentive for the AO to ensure consistency of the 

Flight plan EOBT with SOBT 

⇒Incentive for AOs to cancel ghost flights and 

duplicates

DPI and FPL Consistency 

Consistency of DPI messages with Flight plan and ICAO 

rules for management of updates must be ensured 

Principle for consistent A-CDM and FPL data 

- DPI and FPL are sharing g Off Block Time and Aircraft type. yp 

- Inform all users about discrepancies through CFMU terminal 

Aos 

T Towers 

FMPs 

- start-up p clearance denied if discrepancy p y is not resolved 

- Make flight plan updates via CHG/DLA compatible with A-CDM 

i.e no disadvantage to Aos filing DLA/CHG but in contrary: 

- CCreate t iincentives ti ffor AO AOs tto kkeep FPL updated d t d in i 

accordance with ICAO rules and in line with A-CDM Information. 


9 07/10/2008

Service Level Agreement 

Data Consistency between DPI messages and Flight plan 

according to ICAO rules must be part of the SLA 

- Bilateral OPS EVAL for each A-CDM 

- Minimum quality of information required according to predefined 

standards before transfer into ops. 

- Included in A-CDM SLA with predefined quality objectives 

- start-up clearance denied if discrepancy is not resolved

The Aircraft Operator Target Take-Off time can be : 

Provisional 

or 

Confirmed 

The The confirmation confirmation of of the the Target Target is is made made by by the the AOC AOC 

or by an authorised person mandated by the AO either 

via CFMU terminal 

or 

using T-DPI message: 

-ATTOT -TO 0900 -STATUS c 


15 07/10/2008




Objective of the T-DPI message 

- Update CASA with TOBT 

- Create incentives for AOs to update 

the flight plan information: DLA, CHG

Tower Departure list 

Objective of the Tower departure list 

In circumstancies where the AO/Handling Agent is fullfilling its contract: 

flight is delivered time or flight is ready early enough for ATC to 

ensure compliance with the CTOT 

but 

later events on taxiways/holding points make it impossible 

provide a solution to ATC to seek changes to the CTOT resolving the problem

Expected benefits for ATFM operations 

- Adherence to the ATFM F slots 

- Increase the reliability of the EOBT and ETOT information 

- Suppress duplicated flight plans and ghost flights. 

- Keep ETFMS updated with the changes of the Take-Off Time for regulated 

flights as well as for the non regulated flights 

- increase the anticipation p of the Take Off Time ==> decrease the 

number of late changes 

- Creates incentives for AOs to keep p flight g plan p information updated p
