Thus, HPL is used to format NIC integrity bounds, HFOM is used to format NAC accuracy bounds and SIL indicates integrity level, that is, the probability of being out of NIC radius. The NACp can be obtained from the operational status message, message frame bits 7780 (or ME bits 4548). Abstract: A new system based on GPS Integrity Beacons (low-power pseudolite marker beacon transmitters situated underneath the approach path) has been developed to provide the highest possible performance (including accuracy, integrity, and availability) for Category III precision landing using the Global Navigation Satellite System (GNSS). With NACp, the 95% horizontal and vertical accuracy bounds can be determined. Total latency is the total time between when the position is measured and when the position is transmitted by the aircraft. Interested parties may refer to United States Code of Federal Regulations (CFR), Part 11, General Rulemaking Procedures, which describes a formal means to petition for exemption. Preamble. However, Type Code and NIC no longer have a one-to-one mapping relationship. (3) The aircraft must transmit its position and velocity at least once per second while airborne or while moving on the airport surface. Navigation Integrity Category (NIC) specifies an integrity containment radius around an aircraft's reported position, as defined in TSO-C166b and TSO-C154c. was granted because multi-frequency/multi-constellation GPS navigation receivers suitable for transport category aircraft that meet the ADS-B Out Rule requirements were not available for purchase or installation in sufficient quantities until closer to 2020. imposes certain conditions, limitations and additional pre-flight responsibilities on the operators. With each evolution of the ADS-B versions, these parameters have been renamed and redefined. The definitions are: The values related to SIL remain the same as shown in Table 1.10.

Integrity is a measure of trust in a sensor's information, and has been used for decades to guarantee safety in life-critical aviation systems. It corresponds to a position containment radius (R C) 10 Larger NIC values indicate better GNSS performance. NICa and NICc number (0 or 1) Return type (int, int) pyModeS.decoder.adsb.nic_b (msg) [source] Obtain NICb, navigation integrity category supplement-b. The Electronic Code of Federal Regulations (eCFR) is a continuously updated online version of the CFR. Comments or questions about document content can not be answered by OFR staff. Processes which address the integrity of staff training must be defined, documented and maintained. In general, there are three types of data quality indicators: Uncertainty indicators: These indicators are introduced in the ADS-B version 0. System Design Assurance (SDA) indicates the probability of an aircraft malfunction causing false or misleading information to be transmitted, as defined in TSO-C166b and TSO-C154c.
