As you approach closer to a VOR station, what happens to the corrections needed to keep the CDI centered?

As you approach closer to a VOR station, the corrections needed to keep the Course Deviation Indicator (CDI) centered become smaller. This phenomenon occurs because the VOR system provides information about your position relative to the selected radial. When you are far from the VOR, even a slight deviation from the radial can result in a larger CDI deflection, requiring more significant corrections. However, as you get closer to the station, the angle of deviation decreases, and you become more sensitive to your position in relation to the radial. Thus, only minor adjustments are necessary to keep the CDI centered, making the corrections smaller as you get nearer to the VOR. This understanding is crucial for effective navigation, particularly during the final stages of an approach to the station.
