Diploma

Hello Khazi,
Diploma in Aeronautical engineering is different than aircraft maintenance course. Former is controlled by AICTE while later is controlled by DGCA.
You will have to beseech your college to get some training. You will not be allowed to touch any commercial aircraft till you do not have liscense from DGCA.

Generally you cannot apply after a diploma, you must complete the first year of a Bachelor's degree in India.You can check DAAD DELHI website and check and also get in touch with them to study in Germany.

Hi S R,
Since, Indian diplomas are not accepted you cannot directly apply now. You can apply only after completing the first year of a Bachelor's degree program or by clearing JEE Advanced.For rest of the University specific requirements you can check DAAD Delhi website.

Hi Jyoti,
Yes, you can apply.You can write to the universities yourself about your IELTS score which seems low for a PG course but they have bridge courses which you can take.

Fee varies depending on the modules you select.
The best way to understand which options are best for you is by visiting us and getting counselling. Have you been counselled yet?
In the (free) counselling session (about 45 minutes), our counsellor will tell you about the course, show your student work, give you a campus tour, and you can even meet students or faculty if you wish.
After you have done this you will be in the best position to see if we are the right institute for you and if so, which course options (modules, length, etc.) you would like to take.

No academic qualification is necessary to join our courses so yes, you can join if you are above 15 years of age.
