I done diploma in E&C after 10th and completed b-tech in correspondence. am i eligible for aeronautical jobs if not suggest me what can i do
You are not eligible for aeronautical jobs. This is because the education requirement to qualify for this job is a bachelors program in aerospace or aeronautical engineering. See details at http://education-portal.com/articles/Aeronautical_Engineer_Educational_Requirements.html. Some of the jobs that you can get with b-tech in correspondence are a scada engineer or a design engineer.
