1. An automatic landing system for an aircraft, comprising:

  • a control device configured to provide positional data for controlling the aircraft;

    a first position or range measuring device configured to detect first positional data of the aircraft;

    a second position or range measuring device configured to detect second positional data of the aircraft; and

    a sensor device configured to detect sensor data from which at least one of a direction in which a landmark is located and a range of the landmark to the aircraft can be determined,wherein the control device is configured to generate a first hypothesis for the determined direction or range of the landmark on the basis of the first positional data and a second hypothesis for the determined direction or range of the landmark on the basis of the second positional data,wherein the control device is configured to either confirm or discard the first hypothesis and the second hypothesis, respectively, using the sensor data detected by the sensor device, andwherein the control device is configured to determine that only positional data, on which a confirmed hypothesis is based, is to be used to control the aircraft.
