Collaborative Decision Making
@ Brussels Airport
What is new for A-CDM at Brussels Airport?
Information
Brochure
June 27 2011
Version 1
From June 27th 2011 onwards the new TOBT-tolerance window will be EOBT-10’/+15’. As long as the value of TOBT lays between
EOBT-10 minutes and EOBT+15 minutes no update of the flight plan is required to receive start-up.
E.g. If EOBT = 10.30 than no update of EOBT is necessary as long as the TOBT-value remains in the window from 10.20 till 10.45.
Why not EOBT-15’/+15’ ? Flights without a CTOT may ask start-up from TSAT-5’ till TSAT+5’. If TSAT would be equal to TOBT 10.20
(earliest case) then the pilot may request start-up at 10.15 which is still within the validity of the Flight Plan. See example below.

What if TOBT is outside this tolerance?
If TOBT is outside the tolerance window: following CDM08-alert will be sent via e-mail to the registered operational CDM e-mail contact
with the specific request to update the EOBT of the flight plan.
Subject : CDM alert: “Callsign” DEP 27-Jun-11 LT CDM08 - TOBT/EOBT discrepancy

BRU/EBBR
TOBT : 10:50 UTC is not within the tolerance window of EOBT: 10:30 UTC
Align EOBT with the TOBT in collaboration with your handler
Primary Alert: Start-up will be refused as long as the discrepancy persists.
This message was sent automatically; replies will not be handled
What to do if your flight is restricted by a CTOT?
If you standby for CTOT-improvement nothing should be done and TOBT will remain within the EOBT-tolerance.
However, if it is decided to delay the TOBT outside the EOBT-tolerance, e.g. to embark the passengers at a later time or the flight would
not be ready as foreseen, then the EOBT should be brought in line again with TOBT.
No recalculation of CTOT will happen as long as “newEOBT = TOBT” since CFMU already took into consideration the delayed TOBT.

Should you require any further information on CDM, please contact
Via this address you can request:
1. To obtain free access to the tool “Staff Pages CDM” for your CDM monitoring centres. This web application will allow you to consult,
locally and remote, the status of your flights at any time during the turn-round process at BRU. In addition an extensive CDM-library is
also available (CDM-Info);
2. An additional CDM-Information Session for your operational staff. These 2 hour-sessions are composed of practical Q&A’s to explain
CDM.
3. To register and maintain your operational CDM e-mail contact.

Status CDM-airports
CDM Topics & Highlights
To date there are 4 CDM-airports: Brussels - Frankfurt - Munich and Paris (CDG). Other leading airports are preparing for implementation
by the end of 2011. By then, it is expected that a total of 7 airports will be fully CDM-certified.
Remember: What do we expect from you, Aircraft Operator ?
1. Check if your flight has a valid airport slot
2. Be sure that the initial EOBT (=STD) of your FPL is the same as your airport slot
3. Update your Flight Plan after receipt of a movement message from your Handling Agent or delegate this task (via SLA) to him. When
the Handling Agent delays the TOBT outside the EOBT-TOBT tolerance of -10’/+15’ the EOBT must be updated as well. The sending
of a TOBT is not the equivalent of a Delay Message!!! The obligation to update your EOBT of the FPL remains.
4. Communicate known or expected delays to your Handling Agent and the Airport Partners well in advance, keeping in mind the
EOBT-TOBT tolerance of -10’/+15’.
5. Restricted flights should not update their EOBT/TOBT when a CTOT or an update thereof is received. See also the exceptions Page 1:
“What to do if your flight is restricted by a CTOT?”
6. React onto the alerts. Reply via email is not required.
7. Start-Up Approval, for flights without a CTOT, will only be granted from TSAT-5’ till TSAT+5’. Restricted flights may expect start-up at
TSAT to avoid unnecessary holding and fuel burn at the runway.
8. If you want to leave earlier than EOBT: Update TOBT to maximum EOBT-10’ and check for your TSAT which is sequenced on TOBT.
No early start-up shall be received if the TOBT is not indicating the early readiness. See also “Earliest Case” on Page 1.
If your flight expects to be ready before EOBT-30’: CNL your FPL and refile a new FPL.
9. If you call after TSAT+5’: The Pilot must contact its OCC or accredited Handling Agent to update the flight plan. The Handling Agent
can un-couple the pushback during peak period since TSAT was not respected and no update of EOBT was received.
The resulting IATA-delay code becomes “code 61”!
10. The Flight Plan validity for VFR-flights departing from EBBR (= controlled aerodrome) is also EOBT +/- 15’.
11. Your TSAT can be obtained via voice (Delivery frequency 121.950Mhz) from TOBT-10’ onwards. This is very useful for flights at stands
not equipped with a Docking Guidance System (e.g. Abelag, General Aviation, Brucargo, etc.)..
12. Brief your Staff (Pilots, OCC, etc.).
CDM-results
1. If adherence is measured by compliance EOBT/TOBT at TSAT within tolerance, we conclude that over the first months of CDM-ops the
adherence increased from 97% up to 99,4%..
2. For environmental and economical reasons, Brussels Airport decided to absorb delay as much as possible at the gate and no longer at
the runway. In doing so and thanks to your collaboration an annual saving of 5400 ton of fuel, 17022 ton Co2 and 22 ton NOx were
realized (compared to 2007).
3. The average reduction in outbound taxi time is nearly 3 minutes (or 25% of the total taxi out period).
4. Several OCC-Managers confirm that the volume of “On Time ATFM-slots” increased considerably as well thus reducing the total delay.
Coming Up Next
An update on “CDM under Adverse Conditions” will be done before the start of the next winter season.
