What does dead reckoning navigation rely on?

Dead reckoning navigation relies on computations based on ground speed, track, and elapsed time. This method involves determining one's current position by using a previously determined position and advancing that position based on known or estimated speeds over a certain time interval. By calculating how far the aircraft has traveled and in what direction, pilots can maintain an estimated position even when other navigational aids, such as landmarks or signals, are not available.

This method is particularly useful in situations where visual navigation is not possible or when flying in areas without radio navigation aids, making it a fundamental skill in aviation navigation.
