Hello Bhoomika,
You have completed your Diploma in Computer Science and now is eager to join an aviation course. Right? You have not mentioned what type of Aviation course you are interested but I suppose it could be the course for 'aviation maintenance engineer'. Correct? The eligibility for this course is 12th pass with PCM and as you have completed your Diploma I am sure it should be treated as equivalent to 12th and you should be able to seek admission. Presently in India the Civil Aviation market is growing at an annual rate of about 15% and hence the placements after passing all are very good. Best wishes to you.
