Commercial pilots are trained professionals who fly aircraft for various purposes, including transporting passengers and cargo. They must obtain a commercial pilot's license, which requires extensive flight training, knowledge of aviation regulations, and passing written and practical exams. These pilots work for airlines, charter companies, and cargo carriers, among others. They are responsible for ensuring the safety of their flights, navigating the aircraft, and communicating with air traffic control. Commercial pilots often work irregular hours and may spend long periods away from home, depending on their flight schedules and routes.
