Increased Runway and Airport Throughput

Periodic Reporting for period 3 - PJ02 EARTH (Increased Runway and Airport Throughput)

Reporting period: 2019-01-01 to 2019-12-31

The revised wake separation (RECAT- EU) in Charles de Gaulle Airport and the Time Based Separation (TBS) concept supported by a separation delivery tool at London Heathrow Airport have demonstrated significant arrival efficiency benefits. These concepts are now being extended by the project to departure and mixed-mode operations. The project is also developing other complementary wake separation optimisation concepts. Real time simulation results have shown the potential for additional benefit above that already demonstrated for arrivals. The further development of a delivery tool opens greater opportunities for improving runway occupancy time optimisation and efficient management of Enhanced Approach Procedures in heavy traffic environments.
These Enhanced Approach Procedures that aim to reduce noise impact but also increase runway throughput are developed ensuring their compatibility with a large range of aircraft equipment. This move allows maximising the expected effect of these new procedures that might become one of the most efficient runway throughput enhancement solutions of the project for airport with Heavy and Super Heavy traffic.
For airports operating Medium aircraft fleet, the latest progresses in the definition of the minimum radar performance together with the modelling of collision risk in case of surveillance minima reduction also allow for envisaging massive runway throughput increase.
Analysis has allowed refocusing the ongoing work on arrival and departure traffic optimisation to increase capacity, predictability and punctuality as well as fuel efficiency through management of Integrated Runway Sequence or with a combination of Runway configuration management. Runway throughput is also based on Runway Occupancy Time (ROT) optimisation.
The Project also focus on the access into secondary airport in low visibility conditions.
The Project has also developed and analysed new criteria for designing improved rotorcraft non-interfering simultaneous approach/departure procedures, towards achieving the best operational solution to allow rotorcraft -with a high technological avionics- access to a busy airport (FATO) and reduce environmental and noise impact whilst facilitating increased runway throughput.
WP1 has focussed on maturing its four concept, Arrivals, Departures, Wake Risk Monitoring, and Wake Decay Enhancing Devices.
Several real-time, fast-time and live-trial validation activities have been conducted. Results have been documented in solution data pack.
WP2 finalised the operational and technical use cases and requirements for Enhanced Arrival Procedures using CSPR-ST, SRAP, IGS-to-SRAP, IGS, A-IGS.
Several real-time validations took place at ground and board level. Results have been documented in solution data pack.
WP3 worked on developing and validating the concept of reduction of Minimum Radar Separation based on Required Surveillance Performance.
The operational use cases and requirements have been developed and refined. Three Validations were performed, two fast time and one real time simulations.
Requirements for the controller separation delivery tool to ensure the separations in high-density areas were given to WP1. The tool was used in one WP3 RTS validation.
WP4 made significant progress on the concept of Independent IFR rotorcraft operations at airports. The operational use cases and requirements were developed and refined towards finalizing the Solution Data Pack in 2020. The two flight trials performed between end-2018 and first quarter of 2019 closed the validation path planned for this Solution confirming the expected results.
WP5 performed three validation exercises, one real time and two fast time. Results are documented in the solution data pack.
WP6 focused on developing the concept on Traffic Optimisation on Single and Multiple runways up to a V3 Phase. Several real-time and fast-time validation activities have been conducted. Good results have been documented in solution data pack.
Communication and dissemination activities have been performed through visitor’s days at validations, videos, posters, leaflets and meeting with ANS Providers, Airports and Air Space users.
WP7 focused on the enhancement of the terminal area operations considering efficient curved operations for both arrivals and departures. Good progresses were made in order to meet solution final objectives. Focus Group activities took place to further discuss the concept yielding to the consolidation of each Data Pack documents finalising V1 phase. The V1 Data Pack was delivered and approved in September 2019.
The objective of WP1 has been to conduct the validation of concepts revising wake separation minima in order to increase arrival and departure runway capacity, efficiency, predictability and resilience while maintaining or increasing safety. To mitigate the impact on ATCO workload and Human Performance, and to deliver cost efficiency targets. ATC support tools such as Optimised Runway Delivery for arrival and Optimised Separation Delivery for departure have also been developed. WP1 also validated concepts related to wake risk monitoring and enhancing wake decay.
The objective of WP2 has been to conduct validation of air and ground concepts allowing aircraft to perform complex approaches. The solution will enable mitigation of noise (Environmental Sustainability) and allow for reduced wake separation and consequently runway throughput increase (Capacity and Efficiency).
The objective of WP3 has been to conduct validation of the reduction of minimum radar separation from 2.5NM down to 2.0NM on final approach with a direct positive impact on runway throughput (Capacity, Efficiency and Resilience). Application of reduced separation minima will be dependent on the surveillance performance and will be constrained by other factors such as satisfying the Runway Occupancy Time requirements for arrivals.
The objective of WP4 is to assess and validate a means to move rotorcraft operations from the active runway to improve fixed wing aircraft operations and improve rotorcraft operations by deploying (VFR) FATO procedure. The solution target is to improve capacity, predictability, safety and efficiency by removing the need of separations between fixed-wing aircraft and rotorcraft; as a consequence this leads to an improved flexibility, resilience, access and equity.
The objective of WP5 is to conduct validation of airborne and ground aspects of the concepts enhancing availability and accessibility of secondary airports which are suffering from limited infrastructure both from air and ground perspective, to handle more operations in Low Visibility Conditions, and therefore improving capacity.
The objective of WP6 was to conduct validations of traffic flow optimisation on single and multiple runway airports. Focus is to integrate multiple tactical concepts (wake solutions, dynamic adaption of runways) and ROT information in order to optimize runway throughput (capacity, efficiency) and adapt capacity to traffic demand. An Integrated Runway Sequence function together with support of a Runway Manager(system will support controllers to sequence arrivals and departures according to the runway in use.
The objective of WP7 is to conduct V1 validation of a concept enhancing terminal area operation through the application of Global Navigation Satellite System usage extended to the Terminal Manoeuvring Area.
