A full needle deflection of the CDI means the aircraft is ___ degrees or more off course?

Explanation:
A full-scale deflection on the CDI means you are at the outer limit of what the instrument can display for deviation from the selected course. For a standard VOR/LOC CDI, that outer limit corresponds to about 12 degrees off course. So, when the needle is fully deflected, the aircraft is roughly 12 degrees or more off the desired course. If you see full deflection, you should re-establish and re-intercept the course and use cross-checks with other navigation sources to confirm your position.
