2 Operational Requirements 2.1 General Requirements ADS-B is designed to support numerous applications. Many of these applications are described in this Section and in the Appendices. Since the initial publication of this document, many of the ADS-B Out and ADS-B In applications have undergone a rigorous development of their operational and performance requirements which have been published in other RTCA documents. The high level performance requirements for the ADS-B In applications are summarized in Table 2-7. The high level performance requirements for the ADS-B Out applications are summarized in Table 2-10. This section describes the operational performance requirements for the existing applications and a candidate set of potential future ADS-B applications. A candidate number of scenarios are defined that identify conditions that are driving factors in deriving full capability ADS-B system-wide functional and performance requirements. This candidate set should not be interpreted as a minimum or maximum for a given implementation. Furthermore, all implementations are not required to support all applications. The following key terms are used within this section. � ADS-B Message. An ADS-B Message is a block of data that is formatted and transmitted that conveys the information elements used in the development of ADS-B reports. Message contents and formats are specific to each of the ADS-B data links; these MASPS does not address message definitions and structures. � ADS-B Report. An ADS-B report contains the information elements assembled by an ADS-B receiver using messages received from a transmitting participant. These information elements are available for use by applications external to the ADS-B system. 2.1.1 General Performance 2.1.1.1 Consistent Quantization of Data When the full resolution of available aircraft data cannot be accommodated within an ADS-B Message, a common quantization algorithm shall {242AR2.1} be used to ensure consistent performance across different implementations. To minimize uncertainty, a standard algorithm for rounding/truncation is required for all parameters. For example, if one system rounds altitude to the nearest 100 feet and another truncates, then the same measured altitude could be reported as different values. Unless otherwise specified, whenever more bits of resolution are available from the data source than in the data field into which that data is to be loaded, the data shall (R2.xxx) be rounded to the nearest value that can be encoded in that data field. © 20xx, RTCA, Inc. 13
