According to the invention, the production or calculation of the ground surface is based on measurement data, produced during the approach, from an aircraft-based 3D sensor, with both the production of the 3D measurement data of the ground surface and the definition of the landing point being provided with reference to the same aircraft-fixed 15 coordinate system.
