The people who are in charge of guiding the plane during the flight are the pilot, the co-pilot and the flight engineer. In the past, because the planes were not advanced, there was also a fourth person in the flight cabin, who was called the navigator or director.

pilot or lieutenant; This person is responsible for directing and controlling the aircraft, and he is the main decision-maker regarding flight matters. The co-pilot is the person who sits on the right side of the pilot, he helps the pilot in this serious and sensitive matter, usually if he sees the smallest change, defect, etc., the co-pilot informs the pilot of the flight and takes necessary actions by the co-pilot at the command of the pilot. The pilot takes place to fix the defect or a new phase of the flight.

A third person, called the flight engineer, sits behind the co-pilot. The flight engineer is responsible for controlling the basic parts of the aircraft from a technical point of view, including the engine, navigation devices, cooling systems, aircraft electricity and ventilation, but today, with the increasing progress of computer science and its entry into the aviation industry, flight engineers have lost their jobs. and their duty is handled by the co-pilot with the help of an advanced computer installed in front of him. In the past, the navigator served as the fourth assistant on the plane, but it has been removed from the captain for some time.
In order to become a pilot, people need to pass special courses that pass the entrance exams and medical examinations, which are very important. Students begin their work by passing the P.P.L. course, which requires obtaining a personal pilot’s license.

In the mentioned course, people get acquainted with the basic principles of flight and airplanes, the duration of which is about 300 hours, and in this course, they get to know the basic structure of the airplane and the engine, how the wings of the airplane work and the main parts of the flight, followed by practical flight training. also begins and after the introductory course, the student gets to know the principles and regulations of aviation, which are mostly included in the annexes and appendices of the International Civil Aviation Organization (ICAO).
