The eligibility criteria for a Diploma in Aeronautical Engineering are the completion of 10th standard, or SSC with equivalent examinations from a recognized board. Students must have studied core subjects like Mathematics, Science, and English. They need a minimum aggregate of marks, which can range from 50-60%, depending on the institution. Some colleges may consider students who have completed their 12th standard with a background in science as well. Not always, however. Besides this academic qualification, entrance exams or even state-level entrance tests are some criteria for entrance to certain institutions. A student's interest in aviation, good problem-solving abilities, and a passion to work with technology and machinery are valuable traits for potential students.
Age limits are usually between 15 to 21 years, though this can vary by institution. It’s important to check the specific requirements of the college or university you’re applying to, as they may have additional criteria such as interviews or aptitude tests.
