What is the primary use of an artificial horizon in aviation?

The primary use of an artificial horizon in aviation is to depict the aircraft's pitch and bank angles. This instrument, also known as an attitude indicator, provides critical information to pilots regarding the orientation of the aircraft relative to the earth's horizon. It helps pilots maintain proper control of the aircraft, especially in conditions of poor visibility where natural references are not available. By showing whether the wings are level and if the aircraft is climbing, descending, or in level flight, the artificial horizon aids in ensuring safe navigation and maneuvering. Understanding pitch and bank angles is essential for performing turns and climbs correctly, which is fundamental for maintaining control during flight.
