An aircraft light unit comprising: a mounting portion, which is configured for mounting the light unit to an aircraft; and at least one light source (40a, 40b), which is configured for emitting light; wherein the light unit is configured: to emit at least one first output of white light into a predefined first spatial sector, which, when projected onto a horizontal plane, extends over a range of 30° to 40° from a line extending through the light unit on a first side of said line; and to emit at least one second output of white light into a predefined second spatial sector, which, when projected onto the horizontal plane, extends over a range of approximately 120° from the line on an opposite second side of said line; wherein the mounting portion is configured for mounting the light unit to the aircraft in a predefined orientation, in which the line extends in a direction which is parallel to a longitudinal axis of the aircraft so that the predefined first spatial sector, when projected onto the horizontal plane, extends in an area located between a fuselage of the aircraft and the line; and the predefined second spatial sector, when projected onto the horizontal plane, extends from the line to the outside and/or rear of the aircraft; characterized in that the light of the at least one first output of white light comprises a first percentage of radiation having a wavelength that is shorter than a predefined threshold; and the light of the at least one second output of white light comprises a second percentage of radiation having a wavelength that is shorter than the predefined threshold; and the first percentage of radiation is smaller than the second percentage of radiation. a mounting portion, which is configured for mounting the light unit to an aircraft;
