- Q18715687 abstract "A grid compass known as well as grid steering compass, is a navigational instrument that provides a reference direction (relative to north) in the horizontal plane and allows setting a course (horizontal angle respect to this point), by means of a lockable rotating limb and then, follow that course with a simple sight, by keeping the cross axle within the grid's parallel lines.The grid compass beats all other types of compasses from the pilot's point of view, because he doesn't need to "observe constantly" the number (or the division mark) of the wanted course. He just has to be concerned to control that the N/S compass needle lies parallel between the two lines of the central grid. It uses a "working principle" similar to the "compass controlled autopilot".".
