What is the upside-down compass?

The upside-down compass is a navigational tool used primarily in aviation and maritime contexts, designed to maintain a consistent orientation regardless of the aircraft's or vessel's pitch. Unlike traditional compasses that rely on magnetic north, the upside-down compass provides a heading reference that remains stable, even during maneuvers. This helps pilots and sailors avoid confusion and maintain accurate course information under varying conditions. Its unique design enhances safety and efficiency in navigation.
