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
