Abstract: A communication system is disclosed herein and includes aircraft equipment and on-ground equipment and uses a collaborative map, which has a graphic user interface that includes digital layers that each display a different interface view, and a digital assistant to optimize missions of the aircraft on ground and in flight. A first instance of the collaborative map and a first instance of the digital assistant are onboard the aircraft for one or more pilots to view and interact with. At least one second instance of the collaborative map and a second instance of the digital assistant are on-ground for one or more operators to view and interact with. Communications are managed to ensure synchronization of the instances of the collaborative map and the instances of the digital assistant.

Abstract: A method for signaling obstacles present in a space surrounding an aircraft. This method comprises: acquiring, with at least one LiDAR obstacle sensor, positioning data in a reference frame of the obstacle sensor, constructing, during said flight, a three-dimensional map of the surrounding space in a mapping reference frame and positioning the aircraft in the map by applying a simultaneous localization and mapping process based at least on the positioning data, and displaying, during the flight, on a display, an aircraft symbol and a two-dimensional representation of at least a part of the map, each point displayed in the representation being displayed according to a graphic charter taking the associated level of risk into consideration.
