AFCAT EKT Syllabus 2026: Mechanical & Electrical Topics

The AFCAT EKT syllabus for Mechanical and Electrical branches evaluates core engineering fundamentals. Mechanical covers Thermodynamics, Fluid Mechanics, Manufacturing Technology, and Machine Design. Electrical covers Network Theory, Control Systems, Power Systems, and Electrical Machines. Both branches require solving 50 objective questions worth 150 marks within a 45-minute technical test duration.

What is the AFCAT EKT Exam?

The Engineering Knowledge Test (EKT) is a specialized technical assessment conducted by the Indian Air Force (IAF) alongside the Air Force Common Admission Test (AFCAT). While AFCAT assesses general aptitude, verbal ability, numerical ability, and reasoning, EKT specifically tests the technical competency of candidates applying for the Ground Duty (Technical) branch.

Candidates opting for technical roles must possess an engineering degree or equivalent qualification in streams such as Mechanical Engineering, Electrical Engineering, Electronics Engineering, or Computer Science. The test ensures that officers entering the IAF Ground Duty (Technical) stream possess the foundational engineering concepts necessary to handle advanced aeronautical, electrical, and mechanical systems powering military aircraft, radar networks, and weapon systems.

Key Highlights 2026

Understanding the foundational parameters of the test helps aspirants streamline their preparation schedule. The table below outlines the primary highlights for the technical entry assessment:

Syllabus 2026

The syllabus for EKT is divided into General Engineering subjects (common to technical branches) and Specialist Engineering subjects specific to Mechanical and Electrical streams.

Mechanical Engineering Syllabus

The Mechanical Engineering stream tests fundamental concepts across thermal sciences, fluid dynamics, manufacturing technology, and mechanical design.

Electrical Engineering Syllabus

The Electrical Engineering syllabus covers core concepts from basic circuit analysis to advanced power generation and control automation.

Exam Pattern

The EKT question paper consists of 50 questions worth 3 marks each. The test is conducted immediately after the main AFCAT paper for candidates who opt for Ground Duty (Technical).

Candidates must aim for accuracy because incorrect responses incur a negative marking of 1 mark per wrong answer. Unattempted questions carry zero marks. To evaluate your speed and accuracy under strict time constraints, candidates can practice free mock tests for CDS 2027 on ExamBhai to build exam stamina.

Eligibility Criteria

Eligibility parameters are strictly governed by guidelines released on official portals such as afcat.cdac.in.

Age Limit

• Ground Duty (Technical): 20 to 24 years at the time of course commencement.
• Relaxation in upper age limit applies as per official IAF notifications for candidates holding valid Commercial Pilot Licenses issued by DGCA.

Educational Qualification

• Candidates must have scored a minimum of 60% marks in Mathematics and Physics individually at the 10+2 level.
• Must possess a minimum 4-year graduation degree in Engineering/Technology (B.E./B.Tech) from a recognized university, OR must have cleared Section A and B examination of Associate Membership of Institution of Engineers (AMIE) or Aeronautical Society of India with a minimum of 60% marks.

Application Process

Applying for AFCAT and EKT involves a single online registration process:

1. Visit the official C-DAC AFCAT portal (afcat.cdac.in).
2. Click on 'Candidate Login' and complete the basic registration using a valid email ID and mobile number.
3. Fill in personal details, educational qualifications (ensuring 10+2 physics/maths marks exceed 60%), and preferred branch choices.
4. Select Ground Duty (Technical) to opt for the EKT paper in your relevant stream (Mechanical or Electrical).
5. Upload scanned copies of photograph, signature, and thumb impression in the specified format.
6. Pay the online examination fee and submit the application form. Save the confirmation receipt for future reference.

Preparation Strategy

Preparation for EKT requires balancing core conceptual clarity with rapid problem-solving skills due to the strict 45-minute timeline for 50 technical questions.

1. Master Fundamental Engineering Concepts

Focus heavily on basic engineering principles. EKT tests fundamental concepts rather than long, multi-step derivations. Revise basic formulas from Strength of Materials, Thermodynamics, Network Theory, and Control Systems daily.

2. Time Management and Speed Building

With less than 1 minute per question, solving speed is critical. Develop formula cheat sheets and practice rapid numerical solving. Aspirants preparing for combined defense technical exams should regularly attempt specialized quizzes and take CDS 2027 online test series on ExamBhai to improve test-taking pace.

3. Subject-Wise Focus Areas

• For Mechanical: Prioritize Thermodynamics laws, Rankine cycles, Stress-Strain diagrams, Shear Force/Bending Moment concepts, and basic fluid equations.
• For Electrical: Focus on Kirchhoff's Laws, Thevenin/Norton Theorems, Transformer equivalent circuits, DC machine characteristics, and Control System stability criteria.

4. Practice Previous Years' Question Papers

Solve at least 5 to 7 years of previous EKT question papers to understand recurring topic patterns and difficulty levels. Candidates can access CDS 2027 preparation tools on ExamBhai for structured topic wise practice.

Cut-Off Trends

Official cut-off marks are published on official portals including afcat.cdac.in. EKT carries a separate qualifying cut-off in addition to the main AFCAT written exam cut-off.

Historically, maintaining a target score of 45+ marks out of 150 in EKT provides a safe margin above official cut-off thresholds.

Frequently Asked Questions

Q1: Is EKT mandatory for all AFCAT candidates?

No. EKT is mandatory only for candidates who apply for Ground Duty (Technical) branches. Candidates applying exclusively for Ground Duty (Non-Technical) or Flying branches do not need to take the EKT.

Q2: What is the negative marking scheme in AFCAT EKT?

Each correct answer awards +3 marks, while each incorrect answer results in a deduction of 1 mark. Unattempted questions incur no penalty.

Q3: Can I choose my EKT stream during registration?

Your EKT stream (Mechanical, Electrical, or Computer Science) is determined based on the engineering discipline of your qualifying degree during application filling.

Q4: Is EKT conducted on the same day as AFCAT?

Yes. EKT is conducted immediately after the AFCAT main exam on the same day at the assigned exam center.

Q5: What is a safe score in EKT to clear the technical cut-off?

While historical EKT cut-offs range between 18 and 30 marks out of 150, aiming for a safe score of 45 to 50 marks ensures a comfortable qualification margin.

Q6: What degree percentage is required to apply for EKT?

Candidates must have secured a minimum of 60% aggregate marks in their 4-year B.E./B.Tech degree along with at least 60% marks each in Physics and Mathematics in Class 12.
