AMC1 ACNS.C.PBN.210 Position source ED Decision 2019/011/R If other horizontal position sources are available, they may be used to complement the GNSS-computed position, provided that the output position continues to meet the required performance. If the position is no longer available from a GNSS position source and if additional sources are available, the system should revert to the best available source (e.g. the source that can provide the best computed position in terms of accuracy and integrity). Installation of equipment with an ETSO authorisation against ETSO-C115d satisfies the requirement. [Reference: ED-75D § 3.7.3.1.2] [Issue: CS-ACNS/2]
