In a method for producing a light program (22) for controlling lighting in an interior (80) of an aircraft (82) during a flight, a sequence list (2a, b) of phases of the day (4a-l) for a full day is set, wherein a time of day (6), a phase duration (8) and lighting data (La-l) for the lighting are assigned to each phase of the day (4a-l), the appropriate phase of the day (4a-l) is selected from the sequence list (2a, b) as first program section (14a) of a flight program (10) on the basis of the local time (12a) at which the flight starts and the proportional associated phase duration (8) is assigned to the first program section as section duration (16a), the appropriate phase of the day (4a-l) is selected from the sequence list (2a, b) as last program section (14b-e) of the flight program on the basis of the local time (12b) at which the flight lands and the proportional associated phase duration (8) is assigned to the last program section (14b-e) as section duration (16b-e), the flight program (10) between first program section (14a) and last program section (14b-e) is filled with the phases of the day (4a-l), lying therebetween as per the sequence list (2a, b), as program sections (14b-d) and the associated phase durations (8) are assigned to the program sections (14b-d) as section durations (16b-d), at least one of the section durations (16a-e) is scaled on the basis of a scaling prescription in such a way that the overall duration of the flight program (10) corresponds to the flight duration (TF), the flight program (10) runs in time during the flight on the basis of the elapsed flight time (t), wherein the lighting data (La-l) of the respective current program section (14a-e) are output as light program (22) at each instant of the flight time (t).
