COCKPIT INTELLIGENCE DELIVERS SAFER, HIGHER CAPACITY ARRIVAL STREAMS
At capacity constrained airports, traffic demand for runway operations can exceed the runway capacity. Airports are looking at ways to improve runway efficiency, especially under adverse weather conditions, by optimising wake turbulence separation between consecutive aircraft.
This SESAR candidate solution builds on work completed in SESAR1 (solution #16) and SESAR 2020 wave 1 (PJ.01-05) developing time-based separation between consecutive arrivals.
The latest research investigates the delegation of responsibility for separation from air traffic control to the flight crew under instrument flight rules (IFR) conditions. It then becomes the role of the flight crew to apply and maintain the applicable wake turbulence separation with the previous aircraft until touchdown. This is carried out using the avionics capabilities and indicators in the cockpit to monitor and maintain the procedure.
The process is expected to contribute to enhanced runway throughput through the use of dynamic data and achieve more accurate separations than those delivered based on separation support-to-ATC tools such as the optimised runway delivery (ORD) tool. There is an additional safety benefit as the procedure would avoid separation falling below the minimum required separation between a specific pair.
