Major technological advances have occurred in the form of AMLCDs and electronics facilitating the design of the ultimate set of primary cockpit displays. Increased display design flexibility has led to a divergence, as evidenced in several new primary flight display designs. A set of twelve laws are proposed. The application of these laws will result in more cost-effective, reliable, and universal cockpit displays.
