Abstract: Embodiments are directed to systems and methods for providing light communication (LC) for an aircraft. An LC transmitter is mounted on an aircraft fuselage and is configured to broadcast light signals within a defined region outside the aircraft. An LC receiver mounted on the aircraft fuselage is configured to receive light signals broadcast by a remote LC device. A controller is configured to manage LC signals in the aircraft, and an interface is provided between the controller and an aircraft data network. The light signals may be in a visible light spectrum, an invisible light spectrum, or both. The remote LC device may be, for example, a ground station, an aircraft, a ground vehicle, a ship, a building, or a portable transmitter.
