Advantages and Limitation of Map Reading Advantages • The best means of checking dead reckoning • No fix is more precise than a positive identification of an accurately mapped landmark. Limitation • It cannot be used when the ground is obscured by clouds or when flying over water • Landmarks cannot always be readily identified on a chart such as at night or if the chart is incomplete or inaccurate.
