A newer design, the vertical card compass significantly reduces the inherent error of the older compass designs.
It consists of an azimuth on a rotating vertical card, and resembles a heading indicator with a fixed miniature airplane to accurately present the heading of the airplane.
The presentation is easy to read, and the pilot can see the complete 360° dial in relation to the airplane heading. This design uses eddy current damping to minimize lead and lag during turns.
