Separation management from AMU-LED project perspective.

23 July 2021


Air Mobility Urban – Large Experimental Demonstrations (AMU-LED) is an SESAR VLD project that aims to develop a comprehensive concept of operations and definition of urban air missions and verify and validate this concept through simulations and a vast real-flight demonstration campaign. For this purpose, AMU-LED project counts on academic partners with vast background in aeronautic research and industrial partners including drone manufactures, operators and pilots, U-space service providers and communication, navigation and surveillance system manufactures.

For all the above, BUBBLES consortium considers that the AMU-LED provides an interesting framework where test some of the components of the BUBBLES ConOps for separation management. Therefore, when AMU-LED team contacted us to propose to collaborate to apply the BUBBLES model to AMU-LED, we accepted enthusiastically.

When setting up the collaboration framework, BUBBLES team took the opportunity to ask Mr. Ventas-García, from ITG, one of the AMU-LED project partners his opinion about BUBBLES ConOps for separation management. His answer confirmed our thoughts:

The Separation management concept will play a crucial role in the future of urban air mobility. It will be a key enabler for defining tactical deconfliction techniques but also to determine how many drones can be safely accommodated it in our skies. In that sense, AMU-LED see BUBBLES as a promising solution to address those challenges and set the pillars of future mobility.


We find particularly interesting the work that BUBBLES is carrying out to determine the collision probability between drones and between them and manned aircraft. In the coming months, Europe will elaborate a new version of the EU U-space Concept of Operations (ConOps) using the feedback received from all the different SESAR projects. In the case of AMU-LED CONOPS, we propose a layered airspace structure within the Very Low Level (VLL) Airspace to procedurally separate vehicles flows depending on their performance level. In order to define the size of these layers and the safety buffers, it is essential to have specific tools that allow to simulate and calculate the risk of collision. This is where BUBBLES is a reference and this is why AMU-LED is looking forward to collaborate with BUBBLES consortium in the short term. During our collaboration, we will use AMU-LED flight scenarios and BUBBLES expertise and tools to simulate and define the minimum safety distance between in order to support the development of the future Urban Air Mobility ecosystem”.
