Why this classification
The logic behind this classification is simple: to be able to fly in the atmosphere we need to know the environment and the physics of the flight (1A). Then, a skeleton has to be considered to carry all: payloads and the devidces qe need to fly (1B). Propulsion is needed at least to take off (1C), then Equipments and Systems with their connections (1D) and control will allo top keep the flight path (1 E) and, aircrafts must be designed and validated as a whole (1F). The air traffic must be controlled (1G) and adequate airports must be provided (1H). Human factors must always be taken into account (1 I) Innovative aerial systems are continuously developed (1J) Nowadays we are specially involved in development of unmanned systems (1K). Digitalization of industrial processes is crucial also in aeronautics (1L)
