An aeronautical light aid for a vertical takeoff and landing (VTOL) flying object is provided. The aeronautical light aid includes a plurality of first lighting portions buried in a takeoff and landing port and configured to radiate light in a vertically upward direction, a plurality of second lighting portions provided on an outer side of the takeoff and lighting port and configured to radiate light in an externally upward direction, and a landing guide provided at the center of the takeoff and landing port.

An aircraft light comprises a housing, at least one light source to be cooled, the at least one light source being arranged in the housing, a heat sink element thermally coupled to the at least one light source and defining a cooling surface exposable to a cooling airstream for the cooling airstream to flow along the cooling surface in a flow direction. The cooling surface extends between upstream and downstream end portions spaced apart in the flow direction and means for generating a pressure difference between the upstream and downstream end portions of the cooling surface. Due to the pressure difference, a cooling airstream flowing along the cooling surface is created.

A cable distribution assembly is operable to reel in and pay out a cable through a bore. The alignment of the cable in relation to the cable distribution assembly adjusts to restrict contact between the cable and the bole edge. In this manner, friction between the cable and the bore edge, which may damage the cable, is restricted. A base positions adjacent to the bore, aligning the cable in relation to the bore edge. The base includes a concave contour that enables the cable to pass next to the base from a roller that carries the cable through the bore. A shaft drives the roller. Shaft regulators adjustably move horizontally and vertically along a shaft slot in a sidewall to dictate the position of the shaft and the roller that carries the cable. Fasteners secure the shaft regulator into place. A monitoring device provides information on the use of the assembly.

Helipad and helipad illumination system The invention relates to a dynamic helipad illumination system (2) for dynamically illuminating a floor surface or supporting deck of helipad (1) at least partly in order to enable communication of information regarding one or more current local conditions of, at and/or near the helipad. The dynamic helipad illumination system comprises one or multiple illumination elements (3). The system is arranged to bring at least a part (2a) of said one or multiple illumination elements from a first illumination state, in which at least a part of the floor surface or support deck of the helipad is at least partly illuminated by at least a number of said at least part of the one or multiple illumination elements such that at least a part of the floor surface or support deck radiates a first visual appearance which may correspond to at least a first message to be communicated to a helicopter crew or a pilot, into a second illumination state, in which at least a part of the floor surface or support deck of the helipad is at least partly illuminated by at least a number of said at least part of the one or multiple illumination elements such that at least a part of the floor surface or support deck of the helipad radiates a second visual appearance which may correspond to at least a second message to be communicated to the helicopter crew or the pilot.

A system and method for capturing an unmanned aerial vehicle includes a net configured to receive the unmanned aerial vehicle, an infrared emitter arrangement including a plurality of infrared emitters arranged around the net, an infrared sensor mounted to the unmanned aerial vehicle and configured to detect the infrared emitter arrangement, and a processor that is in communication with the infrared sensor and configured to adjust an azimuth and elevation of the unmanned aerial vehicle based on the detected infrared emitter arrangement in a field-of-view of the infrared sensor.

A precision approach path indicator (PAPI) employs an LED light source with first and second arrays of LEDs or other efficient light sources, disposed one above the other and emitting their respective color lights along an optic axis to a collimating lens of focal length f. First and (optional) second aperture plates positioned along the optic axis, each being a respective frame with a cut-out defining a horizontally elongated aperture for light passing along the optic axis. Intermediate aperture plate(s) can be positioned between the first and second aperture plates. The first frame is positioned between the light source and the collimating lens at the focal distance f from the lens. The optional second aperture plate is positioned at the collimating lens and covers top, bottom, and side edge portions of the lens. A planar blade extends from the light source to the first frame and has a distal edge extending across the aperture of the first aperture plate, substantially at the focus of the collimating lens, dividing the beam into white and red sectors. The intermediate aperture plate(s) can be adjusted for optimal separation. The PAPI can be considered to have an illumination portion formed of the light source(s), blade, and first frame; and an imaging portion formed of an enclosure and a lens positioned at its focal length distant from the front frame aperture and edge of the blade.
