Abstract: Disclosed is a method for identifying a landing zone and for displaying on a head-up display system onboard an aircraft, a symbol conforming to the landing zone, the aircraft being apt to fly over a terrain and to land on the landing zone of the terrain. The aircraft is a helicopter, a drone or an electric aircraft with vertical take-off and landing. The method includes at least the following steps:—a hovering phase of the aircraft over the landing zone and acquisition of the geographical position of the landing zone;—a flight of the aircraft towards the landing zone and display on the head-up display system, of a symbol conforming to the landing zone at the measured geographic position.

Abstract: The invention relates to a low density two-component structural void filling composition that is preferably based on epoxy chemistry. It is designed for use on interior honeycomb sandwich structures as edge close-out and corner reinforcement, as well as local reinforcement for mechanical fixation or complex gap filling. The composition is compatible with metal and non-metal constructions that are typically found in aircraft interiors. The cured material has excellent fire, smoke and toxicity properties. Further, the composition has excellent processing attributes due to easy storage, handling, extrudability, filling, grinding, and painting abilities.

Abstract: A material comprising an encapsulated component within a shell, a rupture initiator associated with the encapsulated component, and a polymeric matrix material, wherein the encapsulation is adapted to fail upon activation of the rupture initiator allowing the encapsulated component to be liberated to initiate a reaction or increase the reactivity of the material.
