Browse aircraft Course Deviation Indicators (CDIs) for precise navigation and flight path accuracy. A Course Deviation Indicator connects to VOR, ILS, or GPS avionics to display lateral guidance, helping pilots stay on course during enroute, approach, and landing. We offer certified CDIs and GPS-compatible Course Deviation Indicators from trusted avionics brands, designed for general aviation, experimental, and commercial aircraft. Upgrade or replace your aircraft CDI for improved situational awareness, reliable navigation, and FAA-compliant avionics performance.
