CAA ORS9 Decision No. 1

EFFICIENT DEPLOYMENT SOLUTION

The surveillance system should meet the performance requirements that are necessary to support the provision of air traffic services (ATS). Therefore, before commissioning a new or modified surveillance system, air navigation service providers (ANSPs) should develop a business case to demonstrate that the proposed surveillance system is the most effective solution that safely supports the required operations and among other elements considers efficiency issues (e.g. through-life cost (TLC) and the 1030/1090-MHz radio frequencies (RF) band usage).

One option for the business case would be the use of ADS-B data. When comparing options regarding the 1030/1090-MHz RF band usage, ANSPs should consider the impact not only on their own surveillance systems but also on neighbouring ones.
