AMC6 CAT.OP.MPA.126 Performance-based navigation ED Decision 2016/015/R ALERTING AND ABORT (a) Unless the flight crew has sufficient visual reference to continue the approach operation to a safe landing, an RNP APCH operation should be discontinued if: (1) navigation system failure is annunciated (e.g. warning flag); (2) lateral or vertical deviations exceed the tolerances; (3) loss of the on-board monitoring and alerting system. (b) Discontinuing the approach operation may not be necessary for a multi-sensor navigation system that includes demonstrated RNP capability without GNSS in accordance with the AFM. (c) Where vertical guidance is lost while the aircraft is still above 1 000 ft AGL, the flight crew may decide to continue the approach to LNAV minima, when supported by the navigation system.
