c. Estimating time, speed, and distance
Plotting a course, including: c. Estimating time, speed, and distance
Bottom line
Dead reckoning is navigation solely by means of computations based on time, airspeed, distance, and direction. The predicted heading takes the aircraft along the intended path and the GS establishes the time to arrive at each checkpoint and the destination. GS, heading, and time for any flight can be determined by using the wind triangle.
