Aeronautical engineer is the one who designs aircraft. In the olden days before the inception of aeronautical engineer profession, aircraft designs were prepared by civil engineers. This is the main reason why old aircraft design employed many trusses in the structures because of such they were heavy. One modern design principle is the so called weight-to-strength ratio which contemplates the balance of the aircraft weight and structural strength. Thus, a good aircraft must be lightweight and at the same time structurally strong.
