Complete Guide to NDA medical standards for flying 2026

The Indian Air Force Flying Branch demands the highest medical fitness standards: a minimum height of 162.5 cm, perfect unaided vision (6/6 in both eyes), and strict CP-I colour perception. Candidates must be free from refractive errors, night blindness, and structural deformities to qualify for this prestigious role.

What is the Exam?

The National Defence Academy (NDA) examination is the premier gateway for youth to join the Indian Armed Forces. Conducted by the Union Public Service Commission (UPSC), the NDA exam is a bi-annual national-level test that selects candidates for the Army, Navy, and Air Force. For those aspiring to the Flying Branch of the Indian Air Force, the medical selection process is notoriously stringent, as it requires a level of physiological endurance and sensory precision necessary for handling high-performance aircraft. We at Exam Bhai emphasize that clearing the written exam and SSB is only half the battle; your medical fitness is the final, non-negotiable hurdle.

Key Highlights 2026

• Mandatory Standards: Unlike ground duties, the Flying Branch has zero tolerance for most refractive errors.
• Physical Metrics: Height must be at least 162.5 cm, with weight strictly proportional to height as per official Indian Air Force medical charts.
• Vision Perfection: Vision must be 6/6 in both eyes without glasses, and you must pass the CP-I color perception test.
• Review Process: While some temporary medical conditions allow for a Review Medical Board (RMB), serious conditions like color blindness or permanent structural deficits are grounds for immediate rejection.
• Holistic Evaluation: Examiners conduct thorough checks, including blood tests, X-rays, ECGs, and dental evaluations.

Preparation Strategy

Success in the NDA requires a dual-track strategy. First, master the written syllabus. Second, begin physical conditioning early. We suggest you practice previous year questions for Defence on Exam Bhai to identify your weak areas. Regarding your medical health, do not wait until the last minute. Get a routine check-up to identify minor issues like ear wax, dental cavities, or BMI irregularities, which can be corrected before your medical board.

Cut-Off Trends

Cut-off trends are updated annually by the UPSC. Historically, candidates should aim for at least 350-400 marks in the written exam to feel secure about receiving an SSB call letter. Remember, the final merit list is a combination of written and SSB marks, provided you pass the medical exam.

Frequently Asked Questions

1. Is LASIK surgery allowed for the NDA Flying Branch? No. LASIK or any refractive surgery is strictly prohibited for the Flying Branch because the high-G environment of fighter jets can cause post-surgical complications.

2. What if I am slightly overweight? Weight must be proportional to height. If you are outside the acceptable BMI range, you may be declared 'Temporarily Unfit' and given a short window to reach the required weight, but it is better to maintain an ideal weight year-round.

3. Is color blindness a total disqualification? Yes. For the Flying Branch, you must pass the CP-I standard, which requires perfect color perception. Color blindness is non-negotiable for pilot entry.

4. Can I wear glasses? For the Flying Branch, unaided 6/6 vision is mandatory. You cannot join as a pilot if you require glasses to see 6/6.

5. What is the minimum height for female candidates in the Flying Branch? Female candidates must meet the same height requirement as male candidates for the Flying Branch, which is 162.5 cm.

6. What happens if I am declared 'Temporarily Unfit'? This is not a final rejection. You will be provided with a medical slip explaining the reason (e.g., underweight, high blood pressure) and can appeal to the Review Medical Board (RMB) once the issue is corrected.
