*5.2.4. Path following algorithm*

Path-following algorithm is an advanced concept than all other algorithms because it requires significant computation power. In this method, a path developed by the flight when moving over terrain with the offset being the set clearance. Path-following algorithm generates flight path by tracking and correcting the offsets as the plane travels over the region. The pathfollowing algorithm shown in **Figure 4d** [4, 8, 9].
