What is the significance of pilotage in navigation?

Pilotage is significant in navigation because it involves finding one's way by using visual references on the ground, such as landmarks, terrain features, and navigational aids. This method relies on the pilot's ability to see and interpret these visual cues in conjunction with maps or charts, allowing for a more direct and often more intuitive form of navigation, particularly in areas where other forms of navigation might be less effective.

In contrast, the other options pertain to different aspects of navigation. Automated flight control pertains to using technology to manage aircraft systems without pilot input, which does not directly involve pilotage. Instrument navigation relies on readings from cockpit instruments and does not require visual references outside the aircraft. Lastly, while GPS technology can enhance navigation's accuracy, pilotage specifically emphasizes visual confirmation of position, which does not depend on electronic systems. Thus, pilotage remains an essential skill for pilots, especially in situations where instrument navigation is not feasible or during visual flight rules (VFR) operations.
