Dear Praveen, yes ofcourse you can do M.E/M.Tech in Avionics. M-Tech/M.E in Avionics is also known as Masters in Aeronautical Engineering. The course enables the candidate to explore in depth the field of study concerning aircraft structural components and focuses on developing talented engineers in the field of new aircraft technologies and business management skills.
The duration of M-Tech Avionics is 2 years, which is divided into 4 semesters. Candidates can get admission to this course through GATE in some colleges like IIT Madras, Mumbai etc., and through entrance exams in other private colleges. Candidates with a first-class bachelors degree in Aeronautical Engineering, Electrical Sciences etc. may apply for the same.
Major organisations like TCS, Mahindra, DRDO, ISRO etc. hire these students and the average salary for avionic engineers ranges between INR 35,000 to 50,000 per month.
All the best
Hope this helps
