Subject to EASA’s agreement, where the RNP system does not support the execution of VA, VM, and VI path terminators, the applicant may demonstrate that the aircraft and flight systems allow the flight crew to manually fly the aircraft on a heading to intercept a course or to go direct to another fix after reaching a procedure-specified altitude. The manual execution of VA, VM and VI terminators should be supported by a flight crew workload assessment.

Subject to EASA’s agreement, where the RNP system does not support the execution of CA and FM path terminators, the applicant may demonstrate that the RNP system allows the flight crew to readily designate a waypoint and select a desired course to or from a designated waypoint. The manual execution of CA and FM terminators should be supported by a flight crew workload assessment.
