A-CDM Airport Collaborative
Decision Making
Workshop at Rome Fiumicino Airport
May 23, 2013
The implementation of A-CDM is being
actively encouraged by the sector
organizations for airports (ACI Europe),
airlines (IATA) and ATC (CANSO)
The concept is an integral part of SESAR
(Single European Sky ATM Research) project
and is to be introduced as a Eurocontrol
standard working method within Europe as of
2015

Shared data
- ELDT and ETO over last route point for inbound
flights
- Programmed Parking Bays
- Ready to move status for outbound flights
- Minimum Turn-round Time
- Target Off-Block Time = handling finished
- Target Start-up Approval Time
- Actual Start-up Approval Time
- Actual Off-Block Event
- Target Take Off Time

Airport/Network Integration
BENEFITS
- Allows partners at ADES to have a better
knowledge of the traffic into its destination
- Allows Eurocontrol to know local constraints at
airports
- Provides more accurate timing of traffic
enabling automatic processes such as slot
allocation to be more adjusted to the Airspace
Users needs
- Enables Aircraft Operators to get a better view
on their fleet before departure
Benefits
AIRPORT
- Environmental benefits: less noise pollution
and lower emissions of CO2 (climate
change) and of NOx (local air quality)
- More efficient gate and parking bay
planning and management
- Optimized infrastructure usage and
consequently enhanced airport capacity
Benefits
AIRLINES
- Fuel savings and lower CO2 emissions
(fewer ETS emission rights needed)
- Improved flight and fleet planning
- Shorter Taxi Times and waiting times at
holding points; fewer queues at runways
- Improved on-time performance: greater
passenger satisfaction
[Taxi time before/after A-CDM]
Benefits
HANDLING AGENTS
-Better planning and use of resources
(both manpower and equipment)
-Efficient turn-rounds
-Better coordination resulting in
improved customer satisfaction
Benefits
ATC
Better sequence
planning of departing
aircraft
+ predictability =
Fewer regulations
After FCO/Eurocontrol connection
– Will improve visibility on progress of flight at out station
– Will reduce risk of suspension by Flight Activation Monitoring
– Will improve adjustment of CTOT to the TTOT
Benefits
Airlines save on average a total of 800
minutes’ Taxi Time every day:
it means nearly
10 tons of jet fuel/day less
Since the start of the trials, November
2012, airlines have saved around
1,800 tons of jet-fuel and
€ 1.2 million on fuel costs
Benefits at Fiumicino Airport
9.6 tons per day of jet fuel saved mean a
decrease in CO2 emissions
by 30 tons every day
Since the start of the trials, there’s been a
reduction in CO2 emissions of 5,400 tons
A-CDM and the Environment
at Fiumicino Airport
The main priority is a timely and accurate updating of the target off-block time (TOBT) on FAST, the Airport CDM Platform, taking into account the Minimum Turn-round Time of aircraft. The TOBT is automatically processed by ENAV’s pre-departure sequencing tool, according to an algorithm which considers the Variable Taxi Time in place, resulting in a calculated target start-up approval time (TSAT) shared via FAST.
Definitions
TARGET OFF-BLOCK TIME (TOBT)
The time that an Aircraft Operator or Ground
Handler estimates an aircraft will be ready, all
doors closed, boarding bridge removed, push back
vehicle available and ready to start up/push back
immediately upon reception of clearance from the
Control Tower
What is the TOBT? – Take off from Heathrow (ATOT): 10:00
– Estimated flight time: 60 min.
– Estimated Taxi In Time (EXIT): 8 min.
– Minimum Turn-Round Time (MTTT): 40 min.
– Scheduled/Estimated Off-Block Time (S/EOBT):
12:00
TOBT = 11:55
Exercise #1
EOBT -5 min. allowed
What is the TOBT? – Take off from Heathrow (ATOT): 10:20
– Estimated flight time: 60 min.
– Estimated Taxi In Time (EXIT): 10 min.
– Minimum Turn-Round Time (MTTT): 40 min.
– Scheduled/Estimated Off-Block Time
(SOBT/EOBT): 12:00
TOBT = 12:10
No update of EOBT required (delay < 15 min.)
Exercise #2
What is the TOBT?
– Take off from Heathrow (ATOT): 10:30
– Estimated flight time: 60 min.
– Estimated Taxi In Time (EXIT): 10 min.
– Minimum Turn-Round Time (MTTT): 40 min.
– Estimated Turn-Round Time (ETTT): 50 min.
– Scheduled/Estimated Off-Block Time
(SOBT/EOBT): 12:00
TOBT = 12:30
Update of EOBT = 12:30 required (DLA to Eurocontrol)
Exercise #3
TARGET START UP APPROVAL TIME (TSAT)
The time – provided by ATC taking into account
TOBT, CTOT and/or the traffic situation – when an
aircraft can expect start up/push back approval
How are TSATs
allocated?
