On This Page — AFA Flying Requirements
1. AFA Flying — Who Is This For?
AFA (Air Force Academy) Dundigal near Hyderabad offers Permanent Commission in the Indian Air Force (Flying Branch) through CDS. It is the most medically demanding CDS entry — the A1G1 standard.
- Medical standard
- A1G1 Flying (AFCAT 02/2023 Appendix C, Sl. No. 1) — same standard as AFCAT Flying
- CDS I 2025 vacancies
- 32 posts
- Education
- Degree from a recognised university WITH Physics AND Mathematics at 10+2 level, OR Bachelor of Engineering
- Commission
- Permanent Commission, Flying Branch (Pilot / Navigator)
- Age (normal)
- 20–24 years (DoB 02 Jan 2002 – 01 Jan 2006)
- Age (CPL relaxation)
- Up to 26 years with valid CPL (DoB 02 Jan 2000)
- Marital status
- Below 25 must be unmarried; above 25 may be married (no married accommodation during training)
2. The A1G1 Standard
A1G1 is the Armed Forces' highest medical fitness grade:
- A1 — highest general physical fitness
- G1 — visual standard Grade 1 (most stringent)
This standard was designed for fighter pilots and trainee aircrew who need to:
- Identify targets at distance in high-glare conditions
- Read cockpit instruments accurately under G-force
- Distinguish aircraft navigation lights from background lights at night
- Operate ejection systems safely (hence anthropometry limits)
3. Vision — NIL Myopia Explained
Full vision table (AFCAT 02/2023 Appendix C Sl. No. 1):
| Parameter | AFA Flying Standard |
|---|---|
| Hypermetropia (max) | +1.5 D Sph |
| Manifest Myopia | NIL |
| Retinoscopic Myopia | NIL |
| Astigmatism (max) | +0.75 D Cyl (within +1.5 D total) |
| Visual acuity | 6/6 (one eye) + 6/9 (other eye) |
| Correctable to 6/6? | Only for hypermetropia |
| Colour perception | CP-I |
What NIL Myopia Means
- Not −0.25 D. Not "just a little". Literally zero myopia.
- Even the smallest minus power (−0.25 D) on either manifest or retinoscopic measurement → unfit
- The retinoscopic test (objective) measures the eye's actual optical power regardless of what you report — it cannot be fooled
- Slight long-sightedness (hypermetropia up to +1.5 D) is allowed because it tends to improve with age and is less likely to progress
Disqualifying Visual Conditions
The following are unfit for AFA Flying regardless of corrected acuity:
- Any degree of manifest squint → unfit
- Keratoconus → unfit
- Night blindness → unfit (Certificate per Appendix D required)
- Nystagmus → unfit
- EEG-triggered visual disturbance → unfit
- Lattice degeneration (as per DGMS criteria) → unfit
4. Colour Perception CP-I
CP-I is tested definitively by the Nagel Anomaloscope — the gold standard for colour vision assessment:
| Test Stage | Method | Pass Criterion |
|---|---|---|
| Screening (SMB) | Ishihara pseudoisochromatic plates | All plates correct |
| Definitive (SMB/AMB) | Nagel Anomaloscope | Full normal trichromacy |
CP-I vs Other CP Grades
| CP Grade | Description | Required For |
|---|---|---|
| CP-I | Full normal colour vision (Anomaloscope) | AFA Flying, AFCAT Flying |
| CP-II | Near-normal colour vision (Ishihara pass) | IMA, OTA, NDA Army |
| CP Pass | Ishihara pass (mild weakness tolerated) | INA Navy, NDA Navy |
Why CP-I Matters for Flying
- Runway threshold lights: green (30° offset from runway axis), red (beyond threshold)
- Navigation lights: red (port), green (starboard), white (stern/top)
- Signal flares: distinct colour recognition critical for distress signals
- Target markers in combat: accurate colour identification prevents friendly-fire errors
5. Height & Anthropometry
AFA Flying has the most detailed body measurement requirements of all CDS entries. These relate to cockpit fit and ejection-seat safety:
| Parameter | Minimum | Maximum |
|---|---|---|
| Standing height | 162.5 cm (≈ 5 ft 4 in) | — |
| Sitting height | 81.5 cm | 96.0 cm |
| Leg length | 99.0 cm | 120.0 cm |
| Thigh length | — | 64.0 cm |
No regional relaxation applies to AFA Flying height requirements.
Why Anthropometry Matters
- Ejection seat clearance: Too tall (long torso/thigh) → head hits canopy; long thigh → legs hit instrument panel during ejection
- Reach: Too short → cannot reach all controls in all cockpits
- G-suit fit: Standardised to specific body proportions
- Cockpit field of view: Sitting height determines over-nose visibility for landing
Weight Standards
Separate AFCAT Appendix A (male) and Appendix B (female) weight-for-height charts apply to AFA Flying. For overweight exception: BMI < 27 (more lenient than Army's BMI < 25), waist < 94 cm (male), with normal biochemical parameters.
6. Cardiovascular & ECG
AFA Flying is more stringent on cardiac assessment than ground-based CDS entries:
- Resting ECG is mandatory at SMB
- ECG abnormality → echo + treadmill stress test (ETT/TMT) + specialist review
- Borderline ECG findings reviewed by cardiologist and AFMS aviation medicine specialist
- BP > 140/90 → unfit (24-hour ABPM monitoring done before final decision)
- Sinus bradycardia < 50 bpm in a trained athlete → exercise ECG + Holter monitor before clearing
- Any Wolff-Parkinson-White (WPW) pattern → unfit for flying
- Complete RBBB → aviation medicine evaluation required
- Mitral valve prolapse with significant regurgitation → unfit
7. CNS, EEG & Neurological
EEG (Electroencephalogram) is mandatory for AFA Flying candidates in certain circumstances.
EEG Indicated For
- Family history of epilepsy
- Past head injury
- Past neurological or psychological abnormality
- Deemed necessary by the examining officer
Unfit EEG Findings for AFA Flying
- Focal high-amplitude beta activity
- Hemispheric asymmetry > 2.3 Hz
- Generalised slow waves
- Paroxysmal spikes/slow waves on hyperventilation
- Bilateral synchronous or focal paroxysmal spikes/slow waves persisting in post-photic stimulation
- Hemispheric driving response
Non-specific EEG abnormality → neuropsychiatrist opinion → may be acceptable depending on findings.
Other CNS Disqualifiers for AFA Flying
- Any history of epilepsy (fits after age 5) → rejection
- Migraine severe enough to consult a doctor → rejection; single migraine with visual disturbance → unfit
- Severe head injury / burr holes → unfit for flying
- Repeated heat stroke / hyperpyrexia → bars flying duties
- Stammering (significant) → unfit
- Tic or nail-biting combined with excessive sweating → flagged as emotional instability
8. Respiratory
- Bronchial asthma (any history) → unfit
- Exercise-induced bronchospasm → unfit for flying
- Any significant lung disease → unfit
- X-ray Chest PA view done at SMB; any abnormality → specialist evaluation
Additional Spine X-Rays for AFA Flying
In addition to the Lumbosacral spine X-ray required for all CDS entries, AFA Flying requires:
- Cervical Spine AP & Lateral
- Dorsal Spine AP & Lateral
These screen for spinal anomalies that could cause catastrophic injury during ejection-seat activation (which exerts up to 25G compressive force on the spine).
9. LASIK for AFA Flying
LASIK is permitted for AFA Flying, but with the most demanding conditions of all CDS entries:
| # | Condition | AFA Flying | IMA / OTA |
|---|---|---|---|
| 1 | Age at surgery | > 20 years | > 20 years |
| 2 | Post-LASIK wait | Min 12 months, uncomplicated | Min 12 months, uncomplicated |
| 3 | CCT (corneal thickness) | ≥ 450 microns | ≥ 450 microns |
| 4 | Axial length | ≤ 26 mm | ≤ 26 mm |
| 5 | Pre-op refractive error | ≤ ±6.0 D | Within entry limits |
| 6 | Residual refraction | NIL (Pilot/Observer) | ≤ ±1.0 D |
| 7 | Retina | Normal healthy retina | Normal healthy retina |
| 8 | Corneal topography | Normal, no ectasia markers | Normal, no ectasia markers |
| 9 | Certificate | From operating medical centre — mandatory | From operating medical centre — mandatory |
RK (Radial Keratotomy) → permanently unfit for all CDS entries including AFA Flying.
10. Age, Marital Status & CPL Relaxation
Source: CDS 2025 Notification para 3(b)(iii), page 7.
| Category | Age Window | DoB Window (CDS I 2025) | Marital Status |
|---|---|---|---|
| Normal eligibility | 20–24 years | 02 Jan 2002 – 01 Jan 2006 | Must be unmarried (below 25) |
| CPL relaxation | 20–26 years | 02 Jan 2000 – 01 Jan 2006 | May be married if above 25 (no married accommodation during training) |
Education Requirements
- Option A: Any degree from a recognised university WITH Physics AND Mathematics at 10+2 level
- Option B: Bachelor of Engineering (B.E./B.Tech)
Why AFA Minimum Age is 20 (Not 19)
Unlike IMA/OTA which start at 19, AFA Flying requires candidates to be at least 20 years old. This is because all candidates must be legal adults for the entire duration of flying training, and the AFCAT/DGCA flying training framework requires adult status from day one of pilot training.
11. Frequently Asked Questions
Can I join AFA Flying through CDS if I wear glasses?
Only if your glasses are for hypermetropia (plus power) up to +1.5 D Sph. Any myopia (minus power) — even −0.25 D — makes you unfit for AFA Flying. There is NO myopia allowance for the Flying branch.
If you have mild myopia, LASIK may help — but it must result in NIL residual refraction and requires 18+ months of planning (minimum 12 months post-LASIK wait, plus time to confirm stable NIL refraction, plus scheduling the SMB).
What is the minimum height for AFA Flying via CDS?
The minimum standing height is 162.5 cm (approximately 5 ft 4 in). No regional relaxation applies to AFA Flying.
In addition: sitting height must be 81.5–96.0 cm, leg length 99–120 cm, and thigh length must not exceed 64 cm. These anthropometric limits relate directly to cockpit fit and ejection-seat safety.
I failed AFCAT medical for colour blindness. Can I apply for AFA via CDS?
No. AFA Flying via CDS uses the identical A1G1 medical standard as AFCAT Flying — including CP-I (full normal colour vision on the Nagel Anomaloscope). If you were assessed as less than CP-I at an AFCAT medical board, the same outcome will occur at a CDS AFA medical board.
There is no treatment or correction for congenital colour vision deficiency. It cannot be corrected by LASIK, glasses, or medication.
Is EEG mandatory for AFA Flying?
EEG is indicated (not universally mandatory) for candidates with: family history of epilepsy, past head injury, past neurological/psychological history, or when deemed necessary by the examining officer.
Abnormal EEG findings — especially paroxysmal spikes, hemispheric asymmetry > 2.3 Hz, or slow waves on hyperventilation — result in an unfit assessment. Non-specific abnormalities may be cleared with a neuropsychiatrist opinion.
I have Physics and Maths at 10+2 and a BCA degree. Can I apply for AFA via CDS?
BCA (Bachelor of Computer Applications) is not a degree in Engineering and does not constitute a B.E./B.Tech. However, the AFA educational requirement is either (a) any degree WITH Physics AND Maths at 10+2 level, or (b) a Bachelor of Engineering.
A BCA from a recognised university may satisfy the "any degree" condition — but you must separately verify that your 10+2 included both Physics and Mathematics as full subjects. If it did, you qualify educationally.
What happens if I have a slight ECG abnormality at the AFA SMB?
An ECG abnormality at SMB leads to temporary rejection and a specialist review — echo (echocardiogram) + treadmill stress test (ETT/TMT). Benign findings such as incomplete RBBB or juvenile T-wave inversion are common in fit young adults and can often be cleared by a cardiologist.
More serious findings (WPW pattern, complete RBBB, significant valve pathology) require aviation medicine specialist evaluation. Do not accept a rejection without a proper cardiologist evaluation.
I am 25 years old with a CPL. Can I apply for AFA Flying via CDS?
Yes. Candidates with a valid DGCA-issued CPL can apply for AFA Flying up to age 26 (born after 02 Jan 2000 for CDS I 2025). Candidates above 25 years may be married.
However, during AFA training they will not be provided married accommodation and cannot live with family outside the academy. The CPL relaxation is only for age — all medical standards (NIL myopia, CP-I, anthropometry) remain exactly the same.
Why does AFA Flying require additional spine X-rays (cervical and dorsal)?
Cervical Spine AP & Lateral and Dorsal Spine AP & Lateral X-rays are mandatory for AFA Flying, in addition to the Lumbosacral spine X-ray required for all CDS entries.
This is specifically to screen for spinal conditions that could lead to catastrophic injury during ejection-seat activation. Ejection exerts enormous compressive force on the spine — up to 25G. Any pre-existing vertebral anomaly, block vertebra, disc disease, or spondylolysis could result in spinal fracture during ejection — hence the additional images are non-negotiable.
