• ED Decision 2016/015/R found in: Air Operations (965/2012) Part-ARO Part-ORO Part-CAT Part-SPA Part-NCC Part-NCO Part-SPO (Feb 2025)

AMC7 CAT.OP.MPA.126 Performance-based navigation ED Decision 2016/015/R CONTINGENCY PROCEDURES (a) The flight crew should make the necessary preparation to revert to a conventional arrival procedure where appropriate. The following conditions should be considered: (1) failure of the navigation system components including navigation sensors, and a failure effecting flight technical error (e.g. failures of the flight director or autopilot); (2) multiple system failures affecting aircraft performance; (3) coasting on inertial sensors beyond a specified time limit; and (4) RAIM (or equivalent) alert or loss of integrity function. (b) In the event of loss of PBN capability, the flight crew should invoke contingency procedures and navigate using an alternative means of navigation. (c) The flight crew should notify ATC of any problem with PBN capability. (d) In the event of communication failure, the flight crew should continue with the operation in accordance with published lost communication procedures.
