HALA¡ celebrated its 5th Summer School at La Granja (Spain)
Sponsored by SESAR, this year’s Summer School on “FUTURE AIR TRAFFIC SYSTEMS BASED ON 4D TRAJECTORY MANAGEMENT” aimed, by combining theory sessions with practical ones, to understand what it is 4D trajectory planning and to analyse the reasons behind the paradigm shift on air traffic management: from a traditional management based on the division of airspace towards an airspace management based on trajectories. Moreover, the course wished to determine the costs and benefits of 4D trajectory, to identify the challenges of 4D trajectory management, to define variables and agents involved in planning of trajectories and finally to frame the 4D trajectory management within the SESAR concept. The course combined theoretical sessions with practical sessions of group work and simulation exercises.
The summer course, celebrated between July 13th and July 16th, served as grounds for bringing together young researches and people from the industry and academia and was a platform to discuss the concept of 4D trajectories and future developments in the field. A group of 31 students from different countries, backgrounds and institutions – academia, research centres, and industry companies (Imperial College, DLR, Deep Blue, UPM, UPV, URJC, UC3M, UPC, CRIDA, INECO, ISDEFE, SENASA, AIRBUS) - attended the course.
One of the interesting aspects of the course was the practical sessions, where the students were divided in 5 different groups and had to discuss several issues proposed by the presenters. Practical sessions were planned for different days of the course. During the first two days, the students participated in brainstorming exercises in groups were they discussed why 4D trajectories are needed and they identified possible benefits and cost of 4D trajectory management. These activities were complemented by several exercises where students simulated the ATCo activities on a simulator. On the third day students worked together in the preparation, definition and execution of a business trajectory by using Jeppesen Jetplan with the objective of defining an optimal trajectory in a given route.
The lectures and tutorials were conducted by relevant experts in the field from different areas of the industry belonging to different companies and institutions (EUROCONTROL, SJU, CANSO, NLR, Deep Blue, CRIDA, Air Europa, AEP, AEMET, ENAIRE, INECO, BRTE, AIRBUS) and academia (UPM, ITU). After the concept of trajectory and 4D trajectory within SESAR was presented, different visions of stakeholders (pilot, AOC, ATCo, Airport, industry, meteo) on requirement for 4D trajectories were introduced. To finalise the course the roadmap for R&D on 4DT was analysed and discussed by students and speakers.
