AMC1 ACNS.C.PBN.205 RNP system approval ED Decision 2019/011/R For all navigation specifications except RNP 0.3: (a) where the RNP system architecture is based on a stand-alone system, the RNP system should be granted a European Technical Standard Order (ETSO) authorisation against the following ETSO: (1) ETSO-C146c (operational Class 3). (2) ETSO-C190 active antenna. (b) where the RNP system architecture is based on a flight management system (FMS) receiving input from various sources of position, the FMS should be granted an ETSO authorisation against ETSO-C115d and, depending on the type of sources to determine position, these should be granted an ETSO authorisation against the following ETSO or be compliant with the following standards: (1) GNSS position source against ETSO-C196a or ETSO-C145c (operational Class 3); (2) GNSS antenna against: (i) ETSO-C144a passive antenna when an ETSO-C196a GNSS position source is installed, or; (ii) ETSO-C190 active antenna when an ETSO-C196a or ETSO-C145c GNSS position source is installed. (3) DME/DME horizontal position source based on a DME interrogator that has been granted an ETSO authorisation against ETSO-2C66b; (4) barometric altimeter: ETSO-C106 Amendment 1. (c) with reference to [CS ACNS.A.GEN.020](#_DxCrossRefBm573002257), any deviations from the ETSOs should be evaluated against the relevant sections of EUROCAE ED-75D Minimum Aviation System Performance Standard (MASPS). (d) noting that there is no equipment standard for INS/IRU horizontal position source, this equipment should comply with the functionality and performance that is detailed in [Appendix B](#_DxCrossRefBm573002384).
