Delco Carousel

From Wikipedia, the free encyclopedia

The Delco Carousel was a popular INS-based navigation automation system for aircraft developed by Delco Electronics. Before the advent of sophisticated flight management systems, the Carousel allowed pilots to automate navigation of an aircraft along a series of waypoints that they entered via a control console in the cockpit. The Carousel used an INS as its position reference for navigation. Many aircraft were equipped with dual or triple Carousels for redundancy.
