Commercial aircraft are large airplanes designed to transport passengers and cargo over various distances. They are typically operated by airlines and can accommodate anywhere from a few dozen to several hundred passengers. These aircraft are built for efficiency, safety, and comfort, featuring advanced technology for navigation and communication. The most common types of commercial aircraft include narrow-body and wide-body planes. Narrow-body aircraft, like the Boeing 737, are often used for short to medium-haul flights, while wide-body aircraft, such as the Airbus A380, are used for long-haul international travel. Both types play a crucial role in global transportation.
