An aerial light show system includes aerial vehicles configured to move along paths consisting of positions while emitting light beams to present an aerial light show of a virtual 3D scene. Each aerial vehicle includes a light source configured to project multiple light beams in multiple specified directions, respectively, wherein the brightness and/or color of each of the multiple light beams is independently controllable. The aerial light show system includes a control system configured to control the movement of the aerial vehicles, to modify the brightness and/or color of (e.g., dim or turn off) a light beam of each aerial vehicle at each position projected in a specified direction that is occluded by the virtual 3D scene, and to not modify the brightness and/or color of a light beam of each aerial vehicle at each position projected in a specified direction that is not occluded by the virtual 3D scene.

There is provided a method of mounting equipment to an aircraft having an empennage. The method comprises mounting equipment to a mounting structure for mounting to the aircraft; removing an access panel from the outer skin of the empennage of the aircraft to reveal an access panel opening into the empennage; and attaching the mounting structure to or within the access panel opening such that at least a portion of the equipment extends beyond the outer skin of the empennage. The shape of the mounting structure at least partly conforms to the shape of the access panel opening. The method also comprises covering the mounting structure and the equipment mounted thereon with a cover, and attaching the cover to the mounting structure or the empennage. An assembly, structure, tailplane and aircraft are also provided.

An aircraft with a safety distance display apparatus that is configured to display a visual indication on an obstacle for representing a current distance between the aircraft and the obstacle, wherein the safety distance display apparatus comprises a first light source that emits a first light signal in a first predefined direction, and a second light source that emits a second light signal in a second predefined direction, and wherein the first light signal crosses the second light signal at a predetermined safety distance from the aircraft.

Techniques and architecture are disclosed for array of light emitting diodes. For example, the array may comprise a plurality of stages, each stage comprising a plurality of light emitting diodes (LEDs) connected to a floating switch, respectively. The LEDs may be arranged substantially linearly on a circuit board in a plurality of clusters, where a distance between adjacent LEDs within a cluster is smaller than a distance between LEDs in adjacent clusters. Adjacent clusters contain LEDs from different stages and each stage contains LEDs in different clusters. The array may be incorporated in a lighting system. The light system may have a closed loop feedback mechanism which directly detects light emitted from a subset of the LEDs and a controller which controls the array based on the detection.
