Traditional ICAO approach: Define the signal in space for various technical systems to ensure interoperability and leave to States to decide which system (s) should be implemented in their airspace. PSR (not standardized) SSR (Mode A/C and/or S) ADS-B (ES, VDL M 4 or UAT) MLAT (being standardized) What is the decision based on?

Sensor characteristics Operational requirements Regional agreements Cost considerations Aircraft equipage Other factors

An ideal situation? Operational scenario Identification of application (s) Determination of Performance requirements Other factors Regional issues Choice of surveillance system (s)

The decision process requires a welldefined required surveillance performance (RSP). In other words, we need to define what we mean by “Performance” in the context of surveillance. Work on RSP has started in ICAO (by the Aeronautical Surveillance Panel (ASP)) A framework for RSP has already been defined.

The RSP framework shows a set of RSP values (e. g. from A 1 to A 10) each of which is associated with set figures for: Accuracy Availability Integrity Latency Update rate Continuity Coverage

Work on RSP faces challenges like; * How would RSP fit in the overall picture? * How does it relate to RNP, RCP and RTSP? * Would it be sufficient to set an RSP value for a given airspace/application? * What other work needs to be undertaken (by ICAO and States) to make meaningful use of RSP? * How is the work on RSP affect the standardization of new surveillance systems?

Conclusions * RSP is much desirable * Work on RSP is in its early stages * Significant operational input is required to progress the work * Setting an RSP value is not enough! (Other studies are needed as well) * Safety and interoperability (e. g. over contiguous FIRs) must be ensured
