People who choose this direction are first required to pass specific courses in one of the military or cargo passenger pilot trends. It should be noted that, contrary to what people think, piloting is not only for passenger planes; there are also pilots who are in charge of directing cargo planes. The high importance of this tendency (cargo direction) is due to the fact that about 35% of industrial products in the world are moved through air routes. However, this tendency is unknown to the majority of people. The important point is that the type of aircraft is common for passenger and cargo airlines because both use fixed-wing aircraft. A military or fighter pilot is also a person who serves in the Air Force and is trained for combat air or ground purposes.
