A low-altitude flight guidance system for an aircraft including a warning generator that generates a warning based upon a predicted position. The system further including a first sensor system having a terrain database and a calculation module that determines a current position of the aircraft with respect to terrain stored in the terrain database and that determines a reference altitude h.sub.DB of the terrain at the current position. The system further includes a second sensor system and a module that determines a predetermined flight altitude difference .DELTA.h.sub.F at the predicted position and terrain data in a region U of the predicted position. Moreover, the system includes an altitude prediction module that predicts an altitude and forwards the predicted altitude to the warning generator. The warning is based upon the aircraft reaching, approaching, or exceeding a warning altitude limit, and the altitude prediction module determination for the predicted position is based upon a prediction set point. The instant abstract is neither intended to define the invention disclosed in this specification nor intended to limit the scope of the invention in any way.
