What is the correct course of action if your CDI shows full deflection after passing the VOR?

When the Course Deviation Indicator (CDI) shows full deflection after passing a VOR, the appropriate response is to adjust your course towards the CDI indication. This occurs because the CDI indicates that you have deviated significantly from your intended course to the VOR.

By adjusting your course towards the CDI indication, you are effectively re-establishing a path that will bring you back on course. The CDI's full deflection shows you're either flying away from the VOR or not maintaining your intended radial. Correcting your heading towards the indication aligns your aircraft back toward the VOR, allowing you to regain navigation and maintain situational awareness.

Other approaches, such as returning to the VOR or performing a circular maneuver, may not be efficient or necessary at this point. Continuing on the current heading would only exacerbate the situation, leading you further off course. Thus, the best action is to realign your heading directly towards the CDI for effective navigation.
