True or False: Dead reckoning uses known landmarks to maintain course, whereas ground reference navigation relies on direction and speed of travel.

The statement that "dead reckoning uses known landmarks to maintain course, whereas ground reference navigation relies on direction and speed of travel" is misleading, making it correct to choose false.

Dead reckoning is a navigation technique that calculates one’s current position based on a previously determined position, using speed, elapsed time, and course direction without relying on external cues or landmarks. It’s focused on estimating where one is by progressing from a known position rather than using visual references.

Conversely, ground reference navigation typically involves using identifiable landmarks to determine and maintain one's course. This method relies heavily on visual cues from the ground to navigate effectively, contrasting with dead reckoning, which does not incorporate sighting landmarks at all.

Thus, the statement conflates the two distinct navigation methods, leading to the conclusion that it is indeed false.
