Advanced RNP allows for the design of optimised routes (E.g. spaced parallel routes) and is further enhanced by on-board performance monitoring and alerting.

Description of the exercises

A validation exercise will be undertaken to assess the operational and technical maturity of Performance-Based Navigation (PBN) in an en-route phase of flight. The analysis will seek to identify outstanding issues for this functionality, as well as for the use of tactical parallel offset instructions rather than radar vectoring by air traffic controllers - a functionality which is expected to reduce controller workload and enhance safety.

Expected benefits

• Enhanced safety
• Reduced controller workload
