Introduction
Aeronautical engineering and aerospace engineering are closely related fields. Aeronautical engineering focuses on designing, developing and maintaining aircraft operating within Earth’s atmosphere. In contrast, aerospace engineering focuses on designing aircraft and spacecraft within and out of the Earth’s atmosphere, but both share a similar understanding of aircraft and spacecraft. In this blog, you will explore in-depth knowledge of aeronautical and aerospace engineering, their key differences, career openings, and many more. You will be able to choose the field that best suits you.
What is the Difference Between Aeronautical and Aerospace Engineering?
| Aspect | Aeronautical Engineering | Aerospace Engineering |
