What does the term "dead reckoning" refer to?

The term "dead reckoning" refers to a navigation method that involves estimating one’s current position by using calculations of direction and distance from a known point. It typically includes tracking speed, time, and heading, allowing pilots to navigate without the immediate aid of landmarks or reliance on external visual references. In essence, dead reckoning provides a systematic way to calculate a path between points based on a previously known position, which is crucial for pilots in various flight conditions, especially where visibility may be limited.

This technique is fundamental in aviation, as it helps in maintaining orientation and ensuring that the aircraft remains on course, even when GPS or other navigational aids are unavailable or unreliable. Understanding dead reckoning is essential for pilots when planning and executing flights, as it reinforces the importance of basic navigational skills alongside more advanced technology.
