Who wouldn't be interested in building large spacecraft, ships, or rockets?

Many Indian students aspire to work as aviation or aerospace engineers. However, individuals make the wrong decisions or do something else due to insufficient knowledge. They don't understand the differences and parallels between aerospace and aeronautical engineering.

Although there are notable differences, aeronautical and aerospace engineering design planes, missiles, and other aircraft.

Our obligation as instructors or career counsellors is to advise those pupils and help them choose the correct professional path.

Let's take advantage of this opportunity to learn about aerospace engineering and aeronautical engineering and how they differ.


What is the definition of aeronautical engineering?

Students interested in building, designing, and repairing airplanes are drawn to aeronautical engineering. In the early nineteenth century, Sir George Cayley coined the term aeronautics to denote the science of flying (who invented the conventional configuration of the airplane). The Wright Brothers eventually comprehended this principle, going on to develop the first aeroplane and becoming the first aeronautical engineer.

In a nutshell, aeronautical engineering is concerned with the invention, building, and administration of transportation vehicles such as aircraft, guns, helicopters, observatories, and other similar vehicles.


What is the definition of Aerospace Engineering?

Aeronautical engineering is concerned with studying aircraft that operate within the atmosphere, whereas aerospace engineering is concerned with studying spacecraft that function both within and outside the environment. Aerospace engineering encompasses the development of airplanes and spacecraft and covers a wide range of topics.

This topic of study encompasses a broader component of engineering that includes several minor fields.

Difference Between Aerospace and Aeronautical Engineering

"Aeronautical Engineering is the study of aircraft that operate both inside and beyond the earth's atmosphere," according to the definition, while "Aerospace Engineering is the science of aeroplanes that operate both within and beyond the earth's atmosphere."

Aeronautical engineering is a subgroup of aerospace engineering, to put it another way.

Apart from this primary distinction, there are a few other distinctions between the two professions. Let's go through each one again to make sure we're on the same page.


Perspectives in India and Overseas

Aeronautical Engineering:

India is on track to become the third-largest civil economy of the world. With over 131 million passengers, our country needs qualified and professional aeronautical engineers to strengthen its aviation business. This means that in the next few years, the scope of aviation engineering will broaden. As a consequence, students should think about this career path if they want to have a great career.


The core profile offers greater prospects outside of India because it is still emerging. There are several high-tech space centres there. They provide cutting-edge educational and working methods. As a result, the aeronautical engineering of other countries is more diversified.


Aerospace Engineering: 

India is on its path to becoming the world's third-largest civil aviation market, as previously stated. The aerospace industry has a budget of over $1.5 billion. Furthermore, India has the global record for the most satellites deployed in a specific mission, and its main space agency, the ISRO, is rated sixth in the world. As a result, India offers various opportunities for aerospace engineers.

There are several opportunities in aviation engineering in nations such as the United States, France, the United Kingdom, Germany, and others.

Set of skills required

Aeronautical Engineering: This field necessitates a high level of technological knowledge and sophisticated abilities. You may read more about the abilities here:

  • Analytical abilities, speed, and accuracy
  • Work focus and meticulous attention to detail
  • Acceptance of responsibility
  • More on alertness and mental presence.



Aerospace Engineering is a highly specialised technical field requiring exceptional mathematical and observational abilities. In this subject, research takes years to finish. Therefore, candidates should be resilient and persistent in their pursuit of the profession. A competent Aerospace Engineer should also possess the following abilities:

Outstanding Science academic background 

  • Strong mathematical, logical, and analytical skills 
  • Ability to work for long periods with intense focus 
  • Scientific knowledge
  • Focus on Details, among other things.


Eligibility Criteria for Aerospace Engineering: 

There are some requirements for this four-year program. To enrol in the course, students must meet the following requirements:

  • Students need have a minimum of 60% in Science (55 percent for SC/ST) to be eligible for Aerospace Engineering (PCM).
  • Students must have a bachelor's degree (BE/B Tech or similar) with at least 60% (55 percent for SC/ST) to be considered for admission to the Aerospace Engineering post-graduate programme.
  • The National Aeronautics and Space Administration (NASA) in the United States advises a degree in Biomedical Engineering, Ceramic Engineering, Metallurgy, Chemistry, Oceanography, Industrial Engineering, Optical Engineering, and Materials Engineering among other fields. For NASA, a PhD is highly recommended.


Eligibility Criteria for Aeronautical Engineering: 

Aeronautical engineering ambitious candidates need to fulfil the eligibility criteria to choose for this four years study. Here are the eligibility requirements in detail:

  • Students in Class 12 should have an average of 70-75 percent in PCM.
  • They must pass JEE Main and JEE Advanced. Their JEE scores are required for acceptance.
  • This career is also open to holders of an Aircraft Maintenance Engineering diploma.
  • Students should complete their bachelor's degree in Aeronautical Engineering before enrolling in post-graduate or certificate courses.
  • A student must pass the GATE exam to obtain a post-graduate degree from institutes like IITs, IISc, and scientific research institutions.


Aeronautical Engineering Salary: 

As a fresher, an Aeronautical Engineer may expect to earn between 5 and 11 lakhs per year (LPA).


Aerospace Engineering Salary: 

As a newbie, an Aerospace Engineer may expect to earn between 6 and 12 lakhs per year (LPA).


The study of aircraft design is available in both aerospace and aeronautical engineering. The main distinction is that aerospace engineering is concerned with aircraft and spacecraft both inside and beyond the atmosphere, whereas aeronautical engineering is concerned with those within. Nevertheless, both are effective in their respective roles. Aerospace engineering, on the other hand, offers many employment options.
