There are a whole lot of institutes that provide the requisite training to qualify anyone to become a pilot. Pilots are highly trained professionals, who either fly airplanes or helicopters to carry out a wide variety of tasks. Except on small aircraft, two pilots usually make up the cockpit crew. The most experienced pilot, the captain is in command and supervises all other crewmembers. The pilot and the co-pilot often called the first officer, share flying and other duties. These duties include communicating with air traffic controllers and monitoring instruments. Some large aircraft have a third pilot depending on the need. However, because new technology on aircrafts can perform many tasks that a third pilot used to do, they have been eliminated.
