Compasses

Compasses are navigational instruments used to determine direction relative to the Earth's magnetic poles. In aviation, compasses are essential for navigation and maintaining heading control. There are two main types of compasses used in aviation: magnetic compasses and gyroscopic compasses. Magnetic compasses use the Earth's magnetic field to determine direction, while gyroscopic compasses use a spinning rotor to maintain a stable heading. Compasses are subject to errors caused by magnetic deviation and variation, as well as aircraft interference. Pilots must be trained to recognize and correct for these errors to ensure accurate navigation and safe flight.
