Every back question from every important book, for all five DGCA papers — Air Navigation, Air Regulations, Meteorology, Technical General and Technical Specific — plus the three ATPL subjects, the A320 type bank and airline entrance papers. 21,278 questions across 436 chapters, with worked solutions, full-length timed exam papers and a readiness engine that predicts your score. Free for life.
The route · five legs
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.
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. Every numerical carries a worked solution with the formula spelled out.
Aircraft Act 1934 and Aircraft Rules 1937, DGCA Civil Aviation Requirements, ICAO Annexes 1 to 19, rules of the air, licensing and ratings, flight crew duty limits, airworthiness and documents, aerodrome markings, search and rescue, accident investigation and AIP India — written the way DGCA asks it.
Aviation meteorology end to end — the atmosphere and ISA, pressure systems and altimetry, wind and the geostrophic balance, clouds and precipitation, thunderstorms, icing, turbulence, windshear, jet streams, the Indian monsoon, tropical systems, and full METAR, TAF, SIGMET and station-model decoding practice.
Principles of flight, aerofoils, lift, drag and the drag curve, stability and control, high-lift devices, stalls and spins, airframes and structures, piston engines, gas turbines, propellers, fuel, electrical, hydraulic and pneumatic systems, instruments, weight and balance and aircraft performance.
Type-specific technical practice for the aircraft on your licence — limitations and memory items, powerplant, electrical, hydraulic, pneumatic and pressurisation systems, flight controls, fire protection, FMS and avionics, plus the performance and loading questions DGCA repeats on the specific paper. Six types, and each one is its own subject with its own paper — a Cessna 152 candidate is never served a DA42 question.
Beyond the five legs
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
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.
Pick an option, get instant right or wrong with the correct answer revealed.
The governing formula sits above the working, so you can revise by formula alone.
Every numerical is solved step by step, written plainly enough for a first-timer.
Each question is labelled with the chapter it came from and whether it is theory or a numerical.
The convergency between two positions A (60°N 020°W) and B (60°N 040°W) is:

The engine
Practice reveals the answer as you go. Test scores you. Exam is a full-length timed paper with nothing revealed until you submit.
Formula box plus a numbered method on the numericals — including the ones the printed keys get wrong.
Every subject's exam is the paper DGCA actually sets — 50 × 2 or 100 × 1, 100 marks, pass at 70, on the clock.
Each question is marked Theory or Numerical and carries its chapter, so you always know what kind of question you just missed.
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.
An Item Response Theory model — the family used to score real standardised exams — predicts your mark on a fresh paper instead of counting ticks.
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 live grid of every question — answered, flagged, untouched. Windowed in long practice sets, never in an exam, where every cell has to be reachable.
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
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.
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.
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.
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.
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
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 Rohit Yeligeti.
“I built the question bank I wanted when I was studying for these papers — every back question in one place, every numerical actually solved, and nobody charging a student pilot ₹3,000 for a PDF.”
The syllabus, subject by subject
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 — 6,986 questions across 155 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.
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.
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.
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.
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.
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.
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.
