Which of the following is a true statement concerning the Global Positioning System?

1. GPS is the only form of navigation necessary for safe flight

2. Navigating by GPS must be integrated with other forms of navigation

3. GPS signals can be affected by terrain

4. GPS is not reliable in urban areas

The correct answer is: Navigating by GPS must be integrated with other forms of navigation

Navigating by GPS must indeed be integrated with other forms of navigation because relying solely on GPS can be risky. While GPS provides accurate positioning information, it functions best when used in conjunction with traditional navigational methods such as pilotage, dead reckoning, and other navigation aids. These methods can enhance situational awareness, particularly in areas where GPS might experience signal degradation or unavailability. For instance, GPS signals can be affected by various factors, including terrain, as outlined in another option, which highlights the need for complementary navigation techniques. In challenging environments, relying on GPS alone could lead to navigation errors. Additionally, integrating GPS with visual references and instruments allows pilots to cross-verify their position, enhancing the safety and reliability of the navigation process. Understanding that GPS is one part of a comprehensive navigational strategy is essential for pilots to maintain situational awareness and ensure safe flight operations.
