The invention relates to a method for adjusting an anchor point of a final leg with respect to a landing entry point for non-precision approach and an avionics computer. The avionics computer includes a processing unit configured to: compare a distance between a first position and a second position, the first position corresponding to a position of an initial anchor point of an initial final leg, and the second position corresponding to a position of a landing entry point of a runway, to a predetermined distance; checking whether the initial and final leg of the virtual path passes through the entrance of the runway; and if the distance between the first position and the second position is less than a predetermined distance and if the initial final leg of the virtual path crosses the entry of the runway, defining the landing entry point as an anchor point for the final leg of the virtual path in the non-precision FLS approach mode, therefore, determining the landing entry point of the final leg of the virtual
