What is one of the primary purposes of traditional magnetic navigation?

The primary purpose of traditional magnetic navigation is to determine direction using magnetic compasses. This form of navigation relies on the Earth's magnetic field, allowing pilots to ascertain their heading and navigate accordingly. Magnetic compasses provide real-time feedback on a pilot's orientation relative to magnetic north, which is essential for piloting, especially in areas where visual references may be limited.

In aviation, knowing the correct heading is crucial for maintaining course and ensuring safe flight operations. While other functions like locating airports or managing passenger limits might be important in their own right, the core aspect of magnetic navigation revolves around understanding direction through magnetic means. This foundational principle enables pilots to navigate accurately across diverse flight paths.
