AMC1 ACNS.C.PBN.610 Source of horizontal position

ED Decision 2019/011/R

As a minimum, the inertial positioning source needs to comply with the criteria of Appendix B. The applicant should, however, demonstrate that circular error of the inertial system supports a safe extraction, as defined in AMC1 ACNS.C.PBN.605 in case of loss of GNSS. This may imply that the design of the inertial position source needs to exceed the performance criteria described in Appendix B.

If the RNP system does not exclude VOR-updating automatically, the applicant should identify any pilot procedures for an aircraft to comply with this requirement.
