The route · five legs
Five DGCA papers.
One flight plan.
AIVR CPL splits the entire DGCA syllabus into five legs. Fly the route and every chapter, back question and full-length paper for that subject is waiting at the waypoint. Five more banks sit beyond the route — the ATPL trio, the A320 and airline entrance.
Air Navigation
The full General Navigation question bank — great circles and rhumb lines, convergency and conversion angle, departure, the triangle of velocities, altimetry, the ASI, compasses and gyros, ADF/NDB, VOR, DME, GNSS, chart work and flight planning. Solved numericals carry the formula spelled out, and the navigation page says exactly how many are done.

Five more banks. Same price.
ATPL is examined as three separate subjects, so it is three separate banks with three separate papers — not one combined one. Alongside them sit the A320 type bank and the airline entrance papers, for the interview stage after the licence.

Inside a question
Not a list.
A worked answer.
Most DGCA question banks dump a PDF on you and call it revision. AIVR CPL grades every MCQ, then shows you the formula and the method — so a back question you got wrong becomes a topic you actually own.
- 01Auto-graded MCQs
Pick an option, get instant right or wrong with the correct answer revealed.
- 02Formula box first
The governing formula sits above the working, so you can revise by formula alone.
- 03Numbered method
A solved numerical is worked step by step, written plainly enough for a first-timer.
- 04Source tagged
Each question is labelled with the chapter it came from and whether it is theory or a numerical.
Air Navigation · Convergency
Numerical
The convergency between two positions A (60°N 020°W) and B (60°N 040°W) is:
A10°
B17.3°✓
C20°
D34.6°
Worked solution
Convergency = Change of longitude × sin(mean latitude)
- 1Change of longitude = 040°W − 020°W = 20°
- 2Both positions are on 60°N, so mean latitude = 60°
- 3Convergency = 20 × sin 60° = 20 × 0.866
- 4= 17.3° — option B

Everything a DGCA
exam needs from you.
Three ways to sit a chapter
Practice reveals the answer as you go. Test scores you. Exam is a full-length timed paper with nothing revealed until you submit.
Worked solutions
Formula box plus a numbered method, written for the numericals first — including the ones the printed keys get wrong.
Real paper shapes
Every subject's exam is the paper DGCA actually sets — 50 × 2 or 100 × 1, 100 marks, pass at 70, on the clock.
Theory and numericals tagged
Each question is marked Theory or Numerical and carries its chapter, so you always know what kind of question you just missed.
Mistakes bank you can practise on its own
Every question you get wrong is saved automatically, per subject. "Practise my mistakes" builds a session out of nothing else — so revision spends its time on exactly what you still haven't learned.
Readiness, not percentage
An Item Response Theory model — the family used to score real standardised exams — predicts your mark on a fresh paper instead of counting ticks.
Paged or list view
One question at a time, or the whole paper stacked so you can scan it the way you would on paper. Your choice is remembered.
A navigator that never hides a question
A live grid of every question — answered, flagged, untouched. Windowed in long practice sets, never in an exam, where every cell has to be reachable.
Progress that survives you closing the tab
Chapters tested, test and practice answers counted separately, weak chapters flagged, and the whole record on your account — so a chapter on your phone and a paper on your laptop are the same progress.

Prediction engine
Know if you'll pass before DGCA does.
The bar is not percent-correct. It is a prediction of your mark on a fresh full-length paper, fitted with an Item Response Theory model — the same family used to score real standardised exams. It knows what a guess is worth, how hard each question is, and how much your score should be trusted yet.
- →Guessing is priced in
You score about a third on a three-option question knowing nothing. Raw accuracy reads far too high at the bottom; the model's guessing floor takes it back out.
- →Difficulty is learned, not assumed
Forty easy questions and forty hard ones give the same raw score and mean completely different things. Each question's difficulty comes from how everyone has answered it.
- →Five out of five is not 100% ready
Every estimate carries a margin of error, and the verdict is read off the bottom of it — so a lucky streak can never claim you're ready. Under 40 scored answers it says "provisional" and tells you why.
- →Practice never moves it
Only Test and Exam answers count. Practice still feeds your mistakes bank and the question's difficulty — it just can't inflate your score.

Who's behind it
An AIVR platform, founded and run by a pilot.
AIVR CPL is an independent platform under AIVR — the same team behind AIVR's DGCA RTR training and AIVR CADET's cadet pilot preparation. It is founded and operated by Shruti Singh.
“I built the question bank I wanted when I was studying for these papers — every back question in one place, the numericals actually solved rather than answer-keyed, and nobody charging a student pilot ₹3,000 for a PDF.”

The syllabus, subject by subject
What the DGCA question
bank actually covers.
Leg 01Air Navigation question bank
The DGCA Air Navigation paper rewards method over memory. The AIVR CPL navigation question bank covers the form of the earth, great circles, rhumb lines and small circles, departure and change of longitude, convergency and conversion angle, the triangle of velocities, time and time zones, the altimeter and pressure levels, the airspeed indicator and the IAS–CAS–TAS chain, direct and remote indicating compasses, gyroscopic instruments, ADF and NDB theory, VOR, DME and radar, GNSS, electronic displays, chart projections and practical flight planning. It is the largest bank on the platform — 5,258 questions across 121 chapters — and the DGCA paper it prepares you for is 100 questions in three hours, marked out of 100 with a pass at 70. Numericals carry a worked solution with the formula written out.
Leg 02Air Regulations question bank
DGCA Air Regulations is a citation paper — you either know which rule says it or you don't. This bank works through the Aircraft Act 1934 and the Aircraft Rules 1937, DGCA Civil Aviation Requirements section by section, ICAO Annexes 1 through 19, the rules of the air and right-of-way, flight crew licensing, ratings, currency and medical requirements, flight duty time limitations, airworthiness and the documents to be carried, aerodrome markings, lighting and signals, altimeter setting procedures, search and rescue, accident and incident reporting, dangerous goods and the AIP India structure. Questions carry their rule or annex reference so revision doubles as a citation drill.
Leg 03Meteorology question bank
Aviation meteorology for DGCA runs from the composition and structure of the atmosphere and the ISA, through temperature, pressure and density, altimetry and QNH, QFE and QNE, wind, the geostrophic and gradient balance, land and sea breezes and mountain waves, humidity, stability and lapse rates, cloud types and formation, precipitation, fog, visibility, thunderstorms and cumulonimbus hazards, airframe and engine icing, turbulence and windshear, jet streams and clear air turbulence, air masses and fronts, the Indian southwest and northeast monsoon, western disturbances, tropical cyclones, and full decoding practice for METAR, SPECI, TAF, SIGMET and station model plots.
Leg 04Technical General question bank
Technical General is the widest DGCA paper. The bank covers principles of flight — aerofoil geometry, lift and the lift equation, drag and the drag curve, lift–drag ratio, stalls, spins and high-lift devices, stability and control in all three axes, manoeuvre and load factor, flight at high Mach — plus airframes and structures, piston engines, carburation and fuel injection, gas turbine engines and their cycles, propellers, fuel, electrical, hydraulic, pneumatic and pressurisation systems, ice and rain protection, landing gear and brakes, flight and engine instruments, weight and balance calculations and aircraft performance including takeoff, climb, cruise, descent and landing data.
Leg 05Technical Specific question bank
Technical Specific is written against the aircraft on your licence, so the bank is organised type by type: limitations and memory items, powerplant and its indications, the electrical system and its buses and generators, hydraulics and flight controls, pneumatics, air conditioning and pressurisation, fuel system and feeding, fire detection and protection, landing gear, brakes and antiskid, the FMS, autoflight and avionics fit, warning and caution systems, and the loading, performance and takeoff data questions DGCA repeats on the specific paper. Six types are live — Cessna 152, Cessna 172 R, DA42 Austro, DA42 Thielert, Piper Archer III DX and Tecnam P2008JC — and each is a separate subject with its own 50-question, 90-minute paper, because a candidate sitting the Cessna 152 paper should never be asked a DA42 question. Back questions are grouped so you can revise one system at a time.
Beyond the fiveATPL, A320 and airline entrance
DGCA examines ATPL as three separate subjects, so AIVR CPL holds them as three separate banks with three separate 100-question papers: ATPL General Navigation, ATPL Meteorology, and ATPL Radio Aids & Instruments. Beside them sit an Airbus A320 type bank of 2,150 questions across 18 chapters, for candidates working towards or already on the type, and an airline entrance bank of 4,878 questions across 74 chapters covering the aptitude, technical and general-awareness ground that Indian carriers test at the hiring stage. All five are open on the same terms as everything else — no separate account, no upgrade, no charge.
How to use itA practice method that works
Start a chapter in practice mode, where the answer and the working are revealed as you go, and use it to build recall rather than to score yourself. When a chapter stops surprising you, run it in test mode — that is what moves your readiness bar. Anything you get wrong lands in the mistakes bank automatically, and "practise my mistakes" builds a session out of nothing else, so your next sitting already knows what to ask you. Once a subject feels solid, sit the full exam paper on the clock with nothing revealed, exactly as DGCA will set it. When your readiness holds above the target line and stops being marked provisional, you're ready for the real paper.
Questions about the questions
FAQ
Is AIVR CPL really free?
Yes — the DGCA question bank is free for everyone, for life. The complete bank, every worked solution, every mock test and the prediction engine are open with no paywall, no trial timer and no card required. There is no paid tier of the question bank to upgrade to — see how that compares to the other DGCA question banks. AIVR CPL also sells optional video classes that teach a paper chapter by chapter — two chapters of the Meteorology course are free to watch — but nothing in the question bank is ever locked behind them.
Which DGCA subjects does the question bank cover?
All five written papers — Air Navigation, Air Regulations, Meteorology, Technical General and Technical Specific — plus the three ATPL subjects, the Airbus A320 type bank and airline entrance papers. Because Technical Specific is sat on one aircraft type, each of the six types is its own subject with its own paper. That is 15 subjects, 21,793 questions and 457 chapters live right now.
What are "back questions"?
Back questions are the previous-year and repeated questions that DGCA has asked in earlier papers — the ones every pilot is told to work through before the exam. AIVR CPL reproduces them question for question from the standard reference books and past papers, with the answer key resolved and the numericals solved.
Do the numerical questions come with solutions?
Many of them do, and the number is growing every week — each subject page prints exactly how many of its numericals are solved. A worked solution is a highlighted formula box with the governing equation, then a numbered method that takes you from the given data to the answer. Where a printed answer key is aeronautically wrong, the solution teaches the correct method and flags the discrepancy instead of repeating it. The ones still being written carry the question and the resolved answer key, and they are free too.
Is this for CPL or ATPL?
Both. The five written papers overlap heavily between the DGCA CPL and ATPL syllabus, and ATPL also gets its own three banks — General Navigation, Meteorology, and Radio Aids & Instruments — each with its own 100-question paper, because DGCA examines ATPL as three separate subjects rather than one.
How does exam mode work?
Exam mode is a full-length timed paper for one subject, with nothing revealed until you submit — no right-or-wrong as you go, no answer key. Every paper is 100 marks and passes at 70: Navigation, Technical General, the ATPL subjects and the A320 are 100 questions in 3 hours; Meteorology and Air Regulations are 50 questions worth 2 marks each in 2 hours; each aircraft type is 50 questions in 90 minutes. A paper never asks the same question twice, and every wrong answer lands in your mistakes bank when it's marked.
Do I need to create an account?
You can open the question bank and start practising immediately. An account exists only so your progress, mistakes bank and weak-chapter list follow you between devices — it is never used to gate content.
How does the pass prediction work?
It predicts your mark on a fresh full-length paper rather than counting how many you got right. An Item Response Theory model estimates your ability from your whole scored history, weighted towards your recent answers, using each question's learned difficulty and a guessing floor. The verdict is read off the lower bound of that estimate against the 70 pass mark — so it can't be fooled by a short lucky run — and it stays marked provisional until you have enough scored answers for it to mean anything.
Who built AIVR CPL?
AIVR CPL is an independent platform under the AIVR brand, founded and operated by Shruti Singh — the same team behind AIVR's DGCA RTR training and AIVR CADET's cadet pilot preparation.
Does it work on a phone?
Yes. AIVR CPL runs in the browser on phones, tablets and laptops with no app to install, and your progress is saved as you go, so you can practise a chapter on a phone and finish a mock test on a laptop.
How does AIVR CPL compare to EATPL?
EATPL is a paid DGCA question bank of roughly 20,000 MCQs, sold by subscription. AIVR CPL is comparable in size — 21,793 questions across 15 subjects and 457 chapters — and is free for life with no card and no trial. The difference beyond price is the scoring: AIVR CPL runs full-length timed papers to the real DGCA shapes and reports a readiness percentage with a confidence interval, so it tells you whether you would pass today rather than what you scored last time. Details of any other platform change often; check theirs before deciding.
How does AIVR CPL compare to PilotSphere?
They solve different problems. PilotSphere sells a preparation platform with an AI study assistant, live mentor sessions with line pilots and voice-graded RTR practical scenarios — none of which AIVR CPL offers, and which are worth paying for if that is what you need. AIVR CPL is a free question bank built on depth and honest scoring: Air Navigation alone is 7,751 questions across 176 chapters, against the 1,400+ Navigation MCQs PilotSphere lists, and every subject carries full-length timed papers and a readiness estimate. RTR training lives separately at aivr.in.
Is there a free alternative to the paid DGCA question banks?
AIVR CPL is one. The whole bank is open — 21,793 questions, 15 subjects, timed mock papers and the readiness engine — with nothing held back for a paid tier, because the platform is funded by AIVR's RTR courses rather than by selling the question bank. There is no guest time limit: practise for as long as you like without an account. Signing in with Google is free and is what saves your progress and readiness score across devices, and it is needed for Test mode and a full-length Exam paper because both are marked against an account. See how it compares to the other DGCA question banks.
