Changi Air Traffic Movement
1) Continuous traffic growth
2) Apron Congestion in 2011
• Increase in length of aircraft queue at Runway Holding Point
(generally 8-10 aircraft at the morning peak) caused airlines to burn
additional fuel
• Increase in arrival holding in air between 3pm to 7pm due to apron
congestion
We started thinking about adding new capacity
T5 T4
But this will take time…
In the mean time, we need to optimise current
capacity utilization
Lack of awareness for departure readiness which
result in inefficient stand planning (unnecessary
buffer has to be provided for)
Flight may not depart from the stand at optimal
timing, which result in long queue at holding point.
Under current “First Come First Serve”
planning, we are facing several
challenges:
Motivation to introduce A-CDM “Best Plan Best
Serve” into Changi
• More predictable traffic and better pre-departure sequencing to reduce apron congestion
• Improve flight punctuality and quality of service to passengers
• Efficient utilization of resources including infrastructures and manpower
• Common situational awareness in managing turnaround activities
Journey of Changi A-CDM
The whole A-CDM journey started with a series
of events to create awareness (2012-2013)
IATA workshop on A-CDM in March 2013
ACI Airport CDM in October 2013
Inaugural A-CDM workshop with airlines in September 2013
Next step was to set up core project team
among airport stakeholders (Nov’13)
A-CDM project team consist of
• Changi Airport Group
• Civil Aviation Authority of Singapore
• Hub Carriers
• Main Ground Handlers
External Support:
Together with core team, we worked in 3 work streams for
A-CDM implementation (Dec’13 – Sep’15)
Procedure Systems
Communication
A-CDM is not just a system project Technology is a key enabler for A-CDM
A-CDM is about partnership, communication help to achieve that.
3 work streams for A-CDM
implementation
1st work stream: Procedural Development
• Define 16 A-CDM milestones including
towing
• Define the responsibility of TOBT
submission
• A detailed A-CDM handbook was released
to stakeholders in May 2015.
2nd work stream: System Implementation
Gate Hold Rooms
Operations Control Centers
• view TOBT and TSAT
• update TOBT
• view TOBT and TSAT
• update TOBT
Ramp side
Air Traffic Control Tower
• view TOBT and TSAT
• view TOBT and TSAT
• generate TSAT
Changi
A-CDM
Systems
3rd work stream: Communications
a) 4 A-CDM workshops to engage airlines
on the adoption of procedures and
system development
b) Numerous one-to-one engagement
sessions
c) Periodic A-CDM posters helped to
promote A-CDM awareness.
d) Aeronautical Information Circulars
for pilots
3rd work stream: Communications
Phase 1
• Conducted from July 2014 to December 2014
• TOBT trial with Hub Carriers
• Manual input of TOBT
Phase 2
• TOBT trial with All Airlines
• System generated TOBT + manual change of TOBT if needed
Phase 3
• TSAT trial with pilots
• Sub phase: off peak period -> peak period -> full date
Changi A-CDM full implementation in Q1 2016
Concurrently, Changi is conducting trial in phases to
validate the procedures and systems. (Jul’14 to Feb’16)
Phase 1 trial result:
99.6% Flights with TOBT
manual input
75.4% TOBT updated at -20
min are accurate
80.3% TOBT updated at -10
min are accurate
Observed benefits from phase 1 trial
TOBT was submitted and set up as common
target to achieve for all operational staffs,
hence, less delays were observed.

Lessons Learned Thus Far
A-CDM is not just a system project. Getting partners to
adopt and follow a set of robust procedures is important.
Agreeing on TOBT ownership is critical and the toughest
part.
Transparent and intensive communication with airlines
that were not directly involved in the procedural discussion
is needed, in order to get effective buy-in.
System implementation could be the bottleneck if it was
not driven from the beginning.
Lesson learned
Moving Forward
Linking A-CDM to Multi-Nodal ATFM in Asia
Multi-Nodal
ATFM
• Plans to link ATFM and A-CDM
frameworks, through the
application of CTOT, to create
seamless air traffic flow operations
within Changi Airport
• Participating Airports share local
A-CDM information such as
TOBT/TSAT to each other for
advanced traffic planning.
• Accords greater flexibility to
airspace users to manage delays
through collaboration and
negotiation with ANSPs and
Airport Operators within existing
ATC procedures and constraints
