Abstract

A high lift system for an aircraft with at least one high lift flap arranged on each of the main wings of the aircraft. The high lift system includes an input device for the generation of flight phase-related requirements for the high lift flap. The high lift system further includes a control device, with a conversion function with which the flight phase-related requirements are converted into setting commands for the actuation of a lift device for the adjustment of the high lift flap. The conversion function is configured such that from a take-off requirement, a setting command to the drive device is generated with which the leading edge flap of the high lift flap is arranged in a set state in which a gap exists between the leading edge flap and the main wing with a gap width of between 0.1% and 0.4% relative to the local wing chord.
