What Does CDI Stand For?
CDI stands for Course Deviation Indicator
The Course Deviation Indicator (CDI) is an essential navigational tool used in aviation and marine applications. It displays the user's current position relative to a designated flight path or course, indicating whether the vessel or aircraft is on track or deviating from the intended route. The CDI aids pilots and mariners in maintaining accurate navigation by providing visual feedback on course corrections needed to return to the desired trajectory.
