Hello Ashvin,
As you are doing diploma in EEE, I suggest you to go for aeronautical engineering after your Diploma. By this way you can be an aeronautical engineer. Secondly, you can do aviation management courses but by that way you can only join the ground force. So its better for you to go for aeronautical engineering.
