OBJECTIVES

To meet the challenge of ensuring excellence in engineering education, the issue of quality needs to be

addressed, debated and taken forward in a systematic manner. Accreditation is the principal means of

quality assurance in higher education. The major emphasis of accreditation process is to measure the

outcomes of the program that is being accredited.

In line with this, Faculty of Institute of Aeronautical Engineering, Hyderabad has taken a lead in

incorporating philosophy of outcome based education in the process of problem solving and career

development. So, all students of the institute should understand the depth and approach of course to be

taught through this question bank, which will enhance learners learning process.
