Īny failure affecting the ability to execute RF legs shall be annunciated in the pilot’s primary field of view. The guidance/flight control system combination shall achieve the required accuracy using at least “roll-steering” capability.

The guidance systems are required to be capable of commanding up to 30 degrees of bank above 400 ft agl for RNP procedures and also up to 8 degrees below 400 ft agl for RNP AR procedures. If this is not feasible, pilot training to identify and avoid RF legs is also accepted.

The avionics shall not allow selection of a procedure that the aircraft is not capable of executing (e.g.: selection of a procedure containing RF legs, if the aircraft is not approved for such an operation).
