1. A fixed-wing aircraft, at least comprising
at least one vortex generator movable through an outer surface of the aircraft between a retracted state and a fully extended state by at least one electric motor, the at least one electric motor being exclusively adapted to actuate the at least one vortex generator, and comprising
an electronic control unit adapted to control operation of the at least one electric motor for actuation of the at least one vortex generator,
wherein the aircraft comprises multiple vortex generators on each wing,
wherein multiple propeller propulsion units are attached at each wing, sets of at least one vortex generator each are positioned on the wings behind at least two propellers, and the vortex generators of a set located in a given propeller slipstream are actuatable differently from sets located in different propeller slipstreams.
