ECHNICAL BRANCH
ENGINEERING KNOWLEDGE TEST (EKT)

Note: The model question paper only offers a broad overview and does not purport to represent either the syllabus or the pattern of questions that would appear in the Engineering Knowledge Test

SCHEME AND SYLLABUS: Engineering Knowledge Test is a common test aimed at testing the Basic Engineering knowledge of the candidates applied for Aeronautical Engineering Courses. EKT has two parts, namely

  • Part A - General Engineering: 40 Questions | Duration: 1 Hour
  • Part B - Specialist Paper for each Engineering discipline: 35 Questions

Engineering Knowledge Test is pitched at pre-final to final year engineering level. The test consists of two parts viz General Engineering and Specialist subjects for the two streams of Technical Branches i.e Aeronautical Engineering (Electronics) and Aeronautical Engineering (Mechanical). The specialised papers are in Mechanical Engineering, Aeronautical engineering, Electronics and Communication engineering, Electrical and Instrumentation engineering and Computer Engineering.

The questions are objective type in nature and duration of test is approximately one hour. It is mandatory for the candidates to pass in both General and Specialist papers to qualify for AFSB interview.
