AFCAT exam preparation, from the written test to CPSS

The Air Force Common Admission Test is the main door into the Indian Air Force as an officer for graduates. If you want the flying branch, AFCAT is only the first hurdle: after it come the Air Force Selection Board and the CPSS, a pilot aptitude test you can sit only once in your life. Here is how each stage works and how to prepare for it properly.

The route to the flying branch

The sequence is the same every cycle. You clear the AFCAT written exam, you are called to one of the Air Force Selection Boards (AFSB) for several days of testing, flying candidates take the Computerised Pilot Selection System (CPSS) there, and those recommended go on to a medical examination before the merit list.

For the 2026 cycles, flying branch candidates had to be 20 to 24 years old (relaxable to 26 for holders of a valid DGCA commercial pilot licence), with at least 50% in both Physics and Maths at 10+2 plus a qualifying degree. These rules are revised from time to time, so read the notification for your own cycle before you apply.

The AFCAT written exam

It is a computer-based test of 100 multiple-choice questions in 2 hours, for 300 marks. Each correct answer gives +3, each wrong answer costs 1 mark, and an unattempted question gives zero. Candidates for the ground duty technical branch also take a separate Engineering Knowledge Test, which flying candidates do not need.

General awareness (25 questions)

History, geography, polity, sports, culture, defence matters and current affairs. This is pure knowledge: newspapers, a good current affairs digest and steady revision over months.

Verbal ability in English (25 questions)

Comprehension, error spotting, sentence completion, synonyms, antonyms, idioms and phrases. Reading English daily helps more than memorising word lists the week before.

Numerical ability (20 questions)

Decimals and fractions, percentages, ratio, averages, profit and loss, time and work, speed-distance-time, simple and compound interest. The level is school maths. What makes it hard is doing it quickly, without a calculator, while the clock keeps running.

Reasoning and military aptitude (30 questions)

The largest section, with verbal and non-verbal reasoning: number and letter series, analogies, coding, odd one out, figure completion, hidden and embedded figures, mirror images, and spatial questions such as cubes, dice and counting blocks. This is the part of AFCAT closest to the aptitude tests you will meet later at the AFSB.

Cut-offs change every cycle with the number of vacancies and candidates, so aim to be comfortably above recent figures, not just at them. With negative marking, a wild guess loses more often than it helps; guess only when you can eliminate two options.

When is AFCAT 1 2027?

There are two cycles a year. For reference, AFCAT 01/2026 was notified in early November 2025, applications closed on 19 December 2025 and the exam was held on 31 January 2026. AFCAT 02/2026 was held on 8 August 2026. If the usual pattern holds, the AFCAT 01/2027 notification is expected around November 2026, with the exam expected in late January or February 2027. These dates are a forecast, not an announcement: rely only on the official notification.

The AFSB stage

Candidates who clear the written exam report to an Air Force Selection Board. Stage I is a screening: an Officer Intelligence Rating test (verbal and non-verbal reasoning, again) and the Picture Perception and Discussion Test, where you write a story about a picture and discuss it in a group. Many candidates are sent home the same day.

Those screened in stay for Stage II: psychological tests (thematic apperception, word association, situation reaction, self-description), group tasks with a group testing officer, and a personal interview. Flying branch candidates also take the CPSS during this stage, usually towards the end of the board.

CPSS, the test that replaced PABT

CPSS was developed by two DRDO labs, the Defence Institute of Psychological Research and the Aeronautical Development Establishment, and it replaced the older Pilot Aptitude Battery Test (PABT). It is installed at the selection boards in Mysuru, Varanasi and Dehradun. DRDO describes it as assessing information processing speed and accuracy, coordination, visualisation and time-sharing, with candidates performing several tasks at once.

Part 1: the cognitive battery

A series of short computerised tests. Candidates who have sat it describe instrument comprehension (reading dials such as the altimeter, airspeed and attitude indicator to work out what the aircraft is doing), along with reasoning, basic maths, pattern matching and spatial tasks. You must clear this part to go on to the next one.

Part 2: the psychomotor test

You sit in a cockpit-style station with a joystick, rudder pedals and a throttle-type lever, in front of a screen. The tasks are tracking and coordination exercises, some with secondary tasks added on top. Candidates report several attempts per task with the best one counted, but that is from candidate accounts, not an official rule.

Once in a lifetime

This is the part to take seriously. AFCAT notifications state that a candidate who has failed CPSS or PABT in an earlier attempt is not eligible for the flying branch. You can retake AFCAT; you cannot retake CPSS. That is why CPSS preparation deserves weeks of work, not a few videos the night before.

A preparation plan

1. Months before the exam: knowledge. Start general awareness and English early, a little every day. They cannot be crammed, and nothing in an aptitude app replaces them.
2. Eight to ten weeks out: speed maths and reasoning. Fifteen minutes of mental arithmetic and series a day, timed. Learn your squares, common fractions as percentages, and the speed-distance-time shortcuts until they are automatic.
3. Spatial work twice a week. Cube nets, block counting and rotated figures improve fast with practice, and they appear in AFCAT, in the OIR and in CPSS.
4. Full mock tests in the last month. Two hours, 100 questions, real marking. Review every wrong answer and every guess.
5. After the result: CPSS work. Learn to read the six basic flight instruments, then train tracking and divided attention daily until the board. Keep the sessions short and regular rather than long and occasional.

Common traps

Spending too long on one hard maths question and losing three easy ones at the end. Treating negative marking as a reason to leave half the paper blank. Preparing for AFCAT and the interview but walking into CPSS cold. And in the psychomotor test, over-correcting: chasing the target with big joystick movements makes things oscillate, while small steady corrections score better.

How Brain Preflight can help

Brain Preflight has an "Indian Air Force: AFCAT / CPSS" program built from short daily exercises: number and logic series, a mental arithmetic grid, cube nets, block stacks (spotting the mirror image of a rotated stack of cubes), 3D objects for mental rotation, psychomotor tracking, Airways for multitasking, and a 2-back memory task. It trains the same kinds of abilities these tests measure. It does not reproduce the actual AFCAT or CPSS, and it does not cover general awareness, English, the psychological tests, the group tasks, the interview or the medical. Use it alongside your books and mock tests, not instead of them.

Brain Preflight is an independent training app with no link to the Indian Air Force or DRDO. Free tier, works offline. We build it; this guide is part of the same project.
