Modernization of Air Traffic Control (ATC) display systems includes increased use of color to code information. While colors can enhance display designs, human factors issues like legibility and salience manipulation are still problematic. Here, we address some of the potential usability issues with integrating traffic and advanced weather information on controller displays. We argue that color palettes that are not specifically designed for layered data and a large number of objects can create legibility and salience problems. We discuss the use of luminance contrast to manipulate salience and present some empirical data showing that air traffic controllers display large individual differences in their preferred brightness settings. We argue that user adjustments of luminance contrast for salience manipulation must be severely constrained in future ATC displays. We present a prototype color palette that uses color-coding to prioritize display information while maintaining good legibility.

<p>Within the context of SINOPTICA (Satellite-borne and IN-situ Observations to Predict the Initiation of Convection for ATM, 2020-2022) project, the preliminary results of the radar analysis on different convective events affecting Italian airports are presented. Three cases of study have been selected for their relevant impact on the international airports of Milan-Malpensa, Marco Polo-Venice and Bergamo-Orio al Serio. Each one of the three cases has been characterised, identifying the best radar approach to obtain valuable information about weather hazard affecting air traffic management (ATM). This provides helpful information for forecasting and tracking convection around the airports.</p><p>The analysis is based on the mosaic radar images provided by the Italian Civil Protection, which included relevant data such as the top of the clouds, vertically integrated liquid (VIL), and VIL density products. Firstly, different zones around each affected airport were selected to monitor the different phases of the event. The proposed early warning system distinguishes four periods: non-storm alert, pre-alert, alert level 1, alert level 2. The proposed domain to be monitored would have a radius of 75 km from the airport.  The storm alert level 2 period would be considered when VIL radar echoes are above 1 mm within an area about 20 km from the airport, considering 1 km<sup>2</sup> spatial resolution and 5 min. temporal resolution (it is to say, maximum values are computed for each variable each 15 min.). The storm alert level 1 period would start two hours before the alert period, covering an area of 500 km<sup>2</sup> with a spatial resolution of 3 km<sup>2</sup> and temporal resolution of 15 min. The pre-alert period would correspond to the period between the first appearance of radar echoes on the Italian radar mosaic until the storm alert level 1 period starts. To monitor this period, the proposed spatial resolution is 5 km<sup>2</sup> and temporal resolution would be 30 min. for the whole radar mosaic.</p><p>This procedure would help to identify and track convective storm structures responsible for ATM difficulties. VIL density variable is considered the most suitable candidate to compare the different episodes since they can occur in different seasons. The application of the proposed methodology to the selected cases has shown good ability to efficiently quantify the severity of the thunderstorms. Additionally, various VIL density thresholds have been tested as severity indicators. Results show that in the three cases, storms developed at certain region past the Alps Mountain range that acts as a natural border north of Italy; then storms moved East and South-East. Maximum VIL density values in the affected region exceed 4 g/m<sup>3</sup>, however, on some occasions, they exceed 8 g/m<sup>3</sup>. VIL density showed a weak seasonal dependency with slightly higher values for summer events. A more detailed analysis comparing impacts and VIL density values is currently ongoing as part of the SINOPTICA project.</p>

Under convective weather conditions, aircraft rerouting in terminal airspace is essential to ensure flight safety and reduce air traffic delays. Traditional air traffic rerouting approaches do not combine convective weather information using radar image recognition with controller workload, additional fuel consumption, delay loss, time cost, and route length at terminal airspace in tactical ATFM phase for exact rerouting decision. In accordance with the safety and economic principles of the route network in terminal airspace and in consideration of the changes in the speed and height of aircraft in terminal airspace, a multiobjective rerouting planning model is established in this study for terminal airspace under convective weather conditions in tactical air traffic flow management phase. Then traffic simulation is conducted to analyze the capacity and delays of the rerouting in the approach path in Shanghai terminal area. Experimental results indicate that this model can increase airspace capacity and operational efficiency of air traffic compared with the traditional air traffic rerouting approaches.
