Navigating instrument that facilitates steering a steady course
Not to be confused with Grid Compass.
Supermarine Spitfire's grid compass
A grid compass[1] known as well as grid steering compass, is a navigating instrument. It is a design of magnetic compass that facilitates steering a steady course without the risk of parallax error.
The grid compass is the simplest steering compass from the pilot's or helmsman's point of view, because he doesn't need to watch the number (or the division mark) of the wanted course. He has only to steer the craft so that the N/S compass needle lies parallel between the lines of the overlay disc. The principle is similar to the compass-controlled autopilot.[2] Although sophisticated electronics have taken over for commercial navigation, light aircraft, gliders and yachtsmen still use the grid compass because of its simplicity and ease of use.
