Abstract: An on-board computing apparatus and associated methods that process aircraft data gathered from aircraft, such as during flight of these aircraft, to pair aircraft during at least portions of a flight route. This enables collaborative airspace management. In certain cases, paired aircraft may be controlled to fly in formation, e.g. flown to maintain a defined separation distance within two- or three-dimensional space over a given period of time. Formation flying in this manner, with pairs of lead and follower aircraft, can allow a follower aircraft to take advantage of a vortex generated by the lead aircraft.

Abstract: An assembly includes a bag and of a composite panel exhibiting a damaged region to be repaired by polymerization of a repair piece using the bag. The bag includes a sheet intended to be laid over the panel. When the panel and the sheet are laid one atop of the other, the sheet exhibits regions capable of absorbing heat emitted by radiation onto it in a proportion that is dependent on the polymerization temperature needed for that region of the panel that corresponds to it, the radiation being partially absorbed by suitable colouration of the sheet in the region concerned. Determining those regions of the panel in which radiation is less well absorbed than in others means that the heating can be adapted to suit the needs of polymerization in terms of repair and that even polymerization can thus be obtained over the entire damaged region, thereby consolidating the repair.
