What does a right course deviation indicator (CDI) deflection indicate when tuned to a VOR?

A right course deviation indicator (CDI) deflection when tuned to a VOR indicates that the aircraft is off course to the right. The CDI shows the relationship between the aircraft's current position and the desired course to the VOR station.

When the aircraft is correctly aligned with the desired VOR radial, the CDI will remain centered, indicating that it is on course. If the indicator deflects to the right, it means that the aircraft's current flight path is to the right of the intended radial, signifying that it needs to turn left to intercept and follow the correct course.

This information is crucial for pilots, as it helps ensure that they can navigate accurately and maintain situational awareness while flying.
