Abstract: A method of developing a flight path for precision flying over an area of interest, the method including, in an electronic processing device, determining coordinate and elevation data relating to an area of interest, using the coordinate and elevation data to determine a flight path including precision paths corresponding to precision flying trajectories and non-precision paths interconnecting at least some of the precision paths, and generating path data at least partially indicative of the flight path, the path data being useable in generating control signals for at least partially controlling operation of the aircraft, in use.
