Civilian aircraft are planes designed primarily for transporting passengers and cargo rather than for military purposes. They come in various sizes and types, including commercial airliners, private jets, and cargo planes. These aircraft are operated by airlines and private companies, providing essential services for travel and trade. Most civilian aircraft are powered by jet engines or propellers and are built to meet strict safety and regulatory standards. They are often equipped with advanced technology for navigation and communication, ensuring safe and efficient flights. Examples of civilian aircraft include the Boeing 737 and the Airbus A320.
