Written history records human efforts and ambitions for flights and flying, at least 2000 years since. Ancient mythologies are filled with flying gods and floating heavens. No wonder, human always felt a deep connection with skies and envied birds and other flying objects for their ability to fly. Our forefathers envisioned wings on their back and flying high, borderless. For them flying was personal, emotional and meant freedom.
Flight, as they comprehended, is not only about defying earth’s gravity to stay afloat, but also gathering direction to the flight, adding control and speed. Three major streams that equipped human achieve this dream, revolves around engineering and technology.
- Aerospace Engineering
- Aeronautical Engineering
- Astronautical Engineering
Prima facie each of the above domains may seem different and unrelated to few, or identical to some; each of them are very much interconnected and mostly rooted on the same basic flight principles, yet, application level very much different, poles apart. They deal with design and development of technologies for achieving flights. Aerospace engineering is the overall domain where flights are achieved both in earth’s atmosphere and beyond. Aeronautical engineering handles the flight in earth’s atmosphere and astronautical engineering deals with flight beyond earth’s atmosphere.
For the flight to be successful, it has to be controlled. Avionics helps in achieving that purpose through high end engineering application of electronics in aviation.
Aviation and aviation management are interrelated fields that surrounds flight and aircraft industry in matters beyond engineering. Management and business related aspects are dealt with greater concern here.
Aerospace (Engineering):
It is the primary field of engineering concerned with the development of aircraft and spacecraft. Or, the domain can be precisely summarized as engineering of flights both in and beyond earth’s atmosphere. Aerospace engineering has two major sub-domains – Aeronautical engineering and astronautical engineering.

Aeronautics (Engineering):
This is the study, design, and manufacturing of air flight–capable machines, and the techniques of operating aircraft and rockets within the atmosphere.

Astronautics (Engineering):
Astronautics or cosmonautics is the theory and practice of travel beyond Earth’s atmosphere into outer space.

Avionics (Engineering):
Avionics systems include the auto-pilot, navigation, communication and flight instruments. Avionics is a field derived from Aviation and Electronics domains. Application of high end engineering in flight control is the the main objective here. While aviation part deals with activities surrounding mechanical flights, electronics includes physics and application of electrons for this purpose.

Aviation & Aviation Management:
In aviation activities surrounding mechanical flight and the aircraft industry are performed. Major sub domains here are Civil Aviation, Military Aviation and Aviation Safety.

Aviation management includes study of airlines, airports and business related to the aerospace industry. It is the domain where managing the operations of the aviation department and ensuring all the maintenance, safety, and scheduling operations are executed properly.

Summary Table:
Sl. No. | Domain | What is? | Courses |
1. | Aerospace (Engineering) | Aerospace is often studied and pursued as a field in engineering. It is the design and development of new technologies in aviation, space, and defense systems.
