A light emitting device includes a light source having a light emitting surface, and a light shielding member located above the light source and having an opening. The light shielding member is movable between (i) a first position in which the opening overlaps the light emitting surface of the light source in a top view, and (ii) a second position, different from the first position, in which the opening overlaps the light emitting surface of the light source in the top view. Light emission of the light source is controllable under a first condition when the light shielding member is in the first position, and is controllable under a second condition when the light shielding member is in the second position.

Boundary information associated with a three-dimensional (3D) flying space is obtained, including a boundary of the 3D flying space. Location information associated with an aircraft is obtained, including a location of the aircraft. Information is presented based at least in part on the boundary information associated with the 3D flying space and the location information associated with the aircraft, including by presenting feedback in proportion to the distance between the boundary of the flying space and the location of the aircraft. An intensity of the feedback increases in proportion to decreasing distance between the boundary of the flying space and the location of the aircraft.

Example implementations relate to systems and techniques for intuitive hot spot demarcation along ground surfaces in order to provide alerts that assist pilots avoid potential collisions. An aircraft computing system may receive map and hot spot data for a taxi route for the aircraft. Based on the map and hot spot data, the computing system may display a representation of the taxi route with a graphical overlay that conveys a position of each hot spot located along the taxi route. The computing system may monitor movement of traffic relative to the taxi route based on traffic data. When traffic is detected proximate a hot spot located along the taxi route, the computing system may provide an alert via the display interface. The alert can increase in intensity based on the location of the traffic relative to the hot spot.

Systems and methods are provided for displaying a landing runway extension on an aircraft. A destination airport of the aircraft is identified based on a flight path of the aircraft received from a flight management system (FMS) of the aircraft. A location of the aircraft is determined based on location data received from at least one geospatial sensor of the aircraft. A landing runway at the destination airport is identified. A display is generated for display on an onboard display device system of the aircraft when the location of the aircraft is within a pre-defined distance from the destination airport. The display includes the landing runway and the landing runway extension associated with a desired final approach flight path to the landing runway.
