1. ADS-B in APAC and ADS-B Benefits The Global Voice of ATM

2. Background
In July 2008, CANSO agreed to conduct a Cost Benefit Analysis for the ADS-B project over the South China Sea involving Indonesia, Vietnam and Singapore.
The study was conducted with the support of IATA and CANSO members (FAA and CAAS) and completed in 2009.

3. Objectives
To determine the benefits & costs of ADS-B implementation for the project
As an example of good governance in developing a business case for the project
To promote regional collaboration and harmonisation among ANSPs and users

7. Study Assumptions ADS-B data sharing across FIRs
Provision of VHF communications to adjacent ANSPs when required
Provision of radar-like separation in restricted airspace
Analysis based on extrapolation of CAAS traffic data and IATA’s demand projections
Estimated infrastructure cost

8. Traffic Demand Forecast
Given the recent economic downturn and the volatility of projections, we conducted a sensitivity analysis based on the following scenarios:
Low: 3% growth
Medium: 5% growth
High: 7% growth
Note: The medium and most probable growth rate for air traffic is set at 5% based on IATA’s Forecast AAGR ( ) for APAC which is 5.9% for pax and 5.4% for freight.

9. Aircraft Equipage
Information presented at SEA ADS-B WG/1 in 2007 showed that about 60% of aircraft in the area were transmitting ADS-B data although this does not take into account the certification or accuracy of the data.
A review of flights operating in the area from Jul- Oct 2008 reinforced this point, where 61.9% were assessed to be ADS-B capable.
25% of the remaining were assessed as retrofit ready (during scheduled maintenance)

10. Aircraft Equipage New aircraft delivered are all ADS-B capable
Fleet retirements due to economic climate will enhance capabilities
Retrofit timelines would be encouraged by an effective mandate
With an effective mandate, more than 85% of aircraft would be ADS-B (Out) capable

12. Benefits - Capacity Increase
Examine delays due to limited capacity vs. the demand forecast.
Examine hourly demand vs. hourly capacity and run a queuing model to estimate delay difference between baseline capacity and new ADS-B enabled capacity
Monetize delay savings benefit in terms of reduced Aircraft Direct Operating Costs and Passenger Value of Time
Example of Hourly Demand

15. Results of Cost Benefit Study (For a 5% medium traffic growth scenario)
Annual savings of nearly 3 million lbs of fuel burn
Annual reduction of 10 million lbs of CO2 emissions
Total Economic savings of over US $ 4m annually
IRR of 22%

16. Other Benefits
Improved safety – enhanced tracking of aircraft, weather deviations etc
Improved surveillance facilitates Search and Rescue efforts
Environmental benefits – greater operational efficiency leading to lower carbon emissions
Improved flight data collection for analysis and planning

17. Recommendation of SEA/BOB ADS-B WG/7
“ADS-B Out” based surveillance applications as modules be included in the Aviation System Block Upgrade Document. These modules should include:
- Improved air traffic operations through provision of surveillance (using ADS-B or radar);
- Improved access to optimum flight levels through climb/descent & cruise using ADS-B or radar; and
Improved safety, efficiency and seamlessness using shared surveillance services across FIR boundaries.
Post Meeting:
ICAO Headquarters accepted this and agreed that an amended ASBU B0-85 Module would be developed to take this into account.
