Integrated methodology for ATM procedure design reducing TMA and en-route operations impact Abstract
This report corresponds to the deliverable D4.1 of the H2020 SESAR CREATE project and compiles the outcomes and work done within CREATE work package 4. Two potential SESAR solutions are proposed in CREATE: a comprehensive multi-scale (from the global to micro) multi-pollutant air quality system (Solution 1); and a framework for multi-aircraft environmentally-scored weather-resilient optimised 4D-trajectories in the flight execution phase (Solution 2). The main contribution of this deliverable is to describe this second solution, which aims at the revision and update process of the reference business trajectory, in the particular case of scenarios disrupted by severe weather conditions, and taking into account the environmental impact of the operations.
In this context, an air traffic control (ATC) decision support tool (DST) is proposed in line with the SESAR extended ATC planning (EAP) and integrated network for (extended) ATC planning (INAP) concepts. The goal is to avoid climate-sensitive areas, while restricting the amount of traffic flying through them. It is expected that this solution could help to manage the transition between planning and execution phases in such disrupted scenarios. Different from (on-going) related research – mainly focused in the dispatch of individual trajectories and/or in air traffic flow management enhancements – the main contribution of the proposed solution 2 is the consideration of the following aspects into an unique problem: i) weather-resilient 4D trajectory (re)planning for the flight execution phase, tackling (near) real-time aspects; ii) consideration of network and safety constraints by optimising the overall set of concerned trajectories in the area of interest; and iii) an environmentally-scored decision making algorithm that would run in this hypothetical ATC DST.
This document reviews the current state of the art in weather/climate/environment optimised trajectories and identifies synergies, gaps and opportunities for further research. A review of the SESAR Concept of Operations (ConOps) 2019 is also performed in order to identify the main concepts underpinning the proposed solution, and align it with the SESAR ConOps. Then, the solution is presented in detail, firstly describing the particular concept of operations of the proposed solution and then outlining a software prototype implementing such solution. The scope of the solution 2 aims at both terminal area and en-route operations. Thus, commonalities and differences are identified in this document, along with the two principal use-cases that set the basis for the validation activities that will be performed in a later stage of the CREATE project
