When using the double track error method, what should you do after you know your deviation?

The double track error method is a navigational technique used to correct an aircraft's course based on its deviation from the intended track. Once you determine your deviation, the appropriate action is to adjust your course by doubling the deviation. This correction compensates for the drift and ensures a more accurate return to the desired track.

By doubling the deviation, you account for both the distance lost to the side of the intended route and the angle of correction necessary to regain the intended path. This approach is particularly effective in dynamic flight environments where maintaining the correct trajectory is crucial for safety and efficiency.

Other options may suggest less effective methods of course correction that could lead to further deviation rather than an accurate return to the desired flight path. Therefore, doubling the deviation for your correction enhances navigational accuracy and helps in properly aligning the aircraft back to its intended course.
