How should a GPS unit be utilized in navigation?

Utilizing a GPS unit as a companion navigational aid alongside pilotage and dead reckoning is the best approach because it integrates multiple methods for improved situational awareness and accuracy in navigation. GPS technology provides precise position information, which can enhance the pilot's ability to navigate, but it should not be relied upon solely.

Integrating GPS with traditional methods such as pilotage, which involves navigating using visual landmarks, and dead reckoning, which relies on estimations of speed, time, and direction, creates a comprehensive navigation strategy. By using the GPS as a supplemental tool, pilots can cross-check their position against visual references and calculated routes, thus enhancing safety and preventing over-reliance on any single navigation method.

Incorporating these diverse techniques helps to build a more robust understanding of the aircraft's location and intended flight path, especially in cases where GPS signals may be unreliable or unavailable. This balanced approach encourages situational awareness and promotes the skills necessary for effective navigation.
