Airport engineering is the branch of aeronautical engineering that applies solid scientific knowledge such as physics, chemistry, materials science, geology and other more specific aspects of the aeronautical-airport sector such as aeronautical infrastructure, theory of structures, airspace management, aerodynamics and flight mechanics, aerospace technology.

It should be noted that although it is true that "airport engineering" is one of the five specialties of aeronautical engineering, it shares a very deep connection with civil engineering given the nature of this career; Therefore, although in Spain this career only qualifies the ing. airports in the design and maintenance tasks of the entire airport facility and infrastructure, this can perfectly be incorporated into the civil engineering labor market around the world.

The aeronautical infrastructure system from the subsoil to space, from ducts and installations many meters deep, to the satellites that rotate with the Earth. It includes two large areas:

At airports, passengers or cargo arriving by car, subway or train are transferred to aircraft or vice versa. The airport is differentiated, in turn, into two areas:
