A Commercial Pilot is a professional pilot who is authorized to fly aircraft for commercial purposes. This means that they are permitted to fly aircraft for a living, such as for airlines, charter companies, cargo operators, or any other aviation-related business. Commercial Pilots may fly a variety of aircraft, including airplanes, helicopters, and other types of flying machines, depending on their training and certification. Commercial Pilots must have extensive knowledge of aviation regulations, navigation, weather patterns, and aircraft systems.
