DGCA CPL syllabus explained subject wise — every paper, topic, marks split and passing criteria for Indian CPL aspirants. Plan your exam prep the smart way.
The DGCA CPL syllabus subject wise comes in six papers, each tested separately at a 70% bar, and each with its own way of catching cadets out. This guide breaks the full DGCA exam syllabus down paper by paper: what’s in it, how it’s tested, which topics carry the most weight, and where most students lose marks. By the end, you’ll know which DGCA CPL ground subjects to clear first and how to plan your prep around the Pariksha calendar.
DGCA CPL syllabus: a subject-wise overview
Before we get into each paper individually, here’s the full picture.The DGCA Commercial Pilot Licence theory exam covers five core papers taken through the Pariksha portal, plus the RTR(A) radio telephony paper, which since November 2025 also sits under DGCA. You need 70% in every paper to pass, with no overall aggregate, so a high mark in one paper can’t carry a fail in another.
Each paper is independent. You can attempt one paper or all five in a single quarterly sitting, and once you clear a subject, the result is valid for five years. The DGCA Pariksha calendar runs every month now, divided between On-Demand and Regular Attempt.
| Paper | Approx. questions | Duration | What it really tests |
|---|---|---|---|
| Air Navigation | ~100 MCQs | ~3 hours | Calculations, chart work, flight planning numericals |
| Aviation Meteorology | ~100 MCQs | ~90 mins | Decoding skill (METAR, TAF) plus systems understanding |
| Air Regulations | ~100 MCQs | ~90 mins | Memorisation of rules, Annexes, and Acts |
| Technical General | ~100 MCQs | ~3 hours | Aircraft systems knowledge, instruments, engines |
| Technical Specific | ~50–100 MCQs | ~90 mins | POH-level knowledge of your trainer aircraft |
| RTR(A) | Practical + written | ~30 mins | Radio phraseology and live communication |
The order in which you take them is your choice, but it shouldn’t be random. Some papers reward memorisation and can be cleared in a few weeks of focused prep; others, especially Navigation and Meteorology, need ongoing practice that takes months to build.
Air Navigation : what’s in the syllabus
Navigation is the most calculation-heavy paper in the DGCA CPL syllabus subject wise breakdown. Roughly 25–30% of questions involve numerical work, and there’s no way to bluff your way through chart problems with surface-level reading.
The syllabus covers:
- Earth and the atmosphere: Earth magnetism, latitude and longitude interpretation, solar time and UTC/LMT conversions, great circle and rhumb lines.
- Chart projections: Lambert’s conformal conic and Mercator projections, scale, departure, D.Long, and convergency calculations.
- Dead reckoning and the wind triangle: wind correction angle, ground speed, true airspeed conversions, ETA calculations.
- Radio navigation aids: VOR, NDB, ILS, DME, ADF principles and limitations.
- Satellite navigation: GNSS, GPS, and RNAV concepts.
- Flight planning: fuel calculations, alternate planning, Equal Time Point (ETP) and Point of No Return (PNR) numericals.
You’ll use the CRP-5 navigation computer through most of the paper. Practising the wind triangle and time-distance-fuel problems on it daily is the single biggest pass-rate lever for this subject. Cadets who only memorise formulas without learning to operate the CRP-5 under time pressure tend to run out of time in the actual exam.
A practical study tip: start chart plotting from week three of your ground school, not week twelve. The chart muscle takes time to build, and there’s no shortcut.
Aviation Meteorology: what’s in the syllabus
Meteorology is half theory and half decoding skill. The textbook material covers everything from atmospheric structure to monsoon dynamics, but the actual paper is dominated by questions that ask you to read a METAR or TAF, interpret a weather chart, or predict conditions based on a frontal description.
The syllabus covers:
- Atmospheric structure: layers of the atmosphere, ISA (International Standard Atmosphere), pressure and altimetry, temperature variations with altitude.
- Clouds and precipitation: cloud formation, cloud types and their flight implications, fog formation, rain, hail, drizzle.
- Pressure systems and fronts: high and low pressure, troughs and ridges, warm fronts, cold fronts, occluded fronts, stationary fronts, and the weather sequence associated with each.
- Hazardous weather: thunderstorms, icing, turbulence, wind shear, jet streams, mountain waves.
- Indian monsoon patterns: southwest and northeast monsoon, pre-monsoon and post-monsoon systems, regional weather peculiarities you’ll encounter on your training routes.
- Aviation weather products: METAR, TAF, SIGMET, AIREP decoding, significant weather (SIGWX) charts, surface analysis charts.
The decoding questions are where most cadets pick up easy marks if they’ve practised, or lose them if they haven’t. Set aside 30 minutes a day for METAR and TAF decoding from week one of your prep, using real Indian aerodrome reports (VABB, VIDP, VOMM, VOBL). By exam day, you should be able to parse a METAR string in under 30 seconds.
Air Regulations: what’s in the syllabus
Air Regulations is the most memorisation-heavy paper in the DGCA CPL exam pattern. It’s also the one cadets most often underestimate. The textbook is dense, the topics overlap, and the actual paper tests obscure clauses that surface-level revision will miss.
The syllabus covers:
- Chicago Convention and ICAO framework: what ICAO does, the 19 Annexes it maintains, and how India implements them through DGCA.
- Key ICAO Annexes: at least 12 of the 19 Annexes appear in the CPL syllabus, with Annexes 1 (Personnel Licensing), 2 (Rules of the Air), 6 (Operation of Aircraft), and 11 (Air Traffic Services) carrying the highest exam weight (source: industry CPL prep guides).
- Indian aviation legislation: the Aircraft Act 1934, Aircraft Rules 1937, and the newer Bhartiya Vayuyan Adhiniyam 2024 which replaces older provisions.
- Civil Aviation Requirements (CARs): particularly Sections 2 (Airworthiness), 7 (Flight Crew Standards), and 8 (Aircraft Operations).
- Operational rules: personnel licensing, rules of the air, ATC procedures, search and rescue, aerodrome standards.
- Annexes 12, 14, 17, 18: search and rescue, aerodromes, security, and the carriage of dangerous goods.
A useful free starting point is our Air Regulations practice quiz, which mirrors the kind of cross-referenced questions the actual paper asks. Cadets who score well on Air Regulations almost always treat it as a reading subject for two months before they touch a question bank, then drill MCQs for the last six weeks.
Technical General: what’s in the syllabus
Technical General tests your understanding of aircraft systems, instruments, and propulsion at the depth a First Officer is expected to know. The prep material is heavy on diagrams, even though the actual exam is text-only MCQs, so visualisation matters.
The syllabus covers:
- Aerodynamics: forces acting on an aircraft, lift and drag generation, stability and control, stall and spin recovery principles, high-speed flight basics.
- Aircraft structures: fuselage, wings, control surfaces, materials, stress and load factors.
- Powerplants: piston engines (carburetors, magnetos, ignition systems), turbine engines (compressors, combustion, turbines), FADEC, propellers, and engine instruments.
- Aircraft systems: fuel systems and management, electrical (alternators, batteries, circuit breakers), hydraulics, pneumatics, environmental control, lubrication.
- Flight instruments: pitot-static instruments (altimeter, ASI, VSI), gyroscopic instruments (attitude indicator, heading indicator, turn coordinator), magnetic compass errors, modern glass cockpit basics.
- Avionics: autopilot principles, navigation displays, basic radar.
The trap with Technical General is that the syllabus reads like a textbook overview, so cadets revise broadly and don’t drill specifics. The exam, by contrast, tests specific values, failure modes, and limitations. Build a personal cheat sheet of the numbers (red-line speeds, system pressures, electrical voltages) and revisit it daily in the final month before your sitting.
Technical Specific: what’s in the syllabus
Technical Specific is the one paper in the DGCA CPL syllabus subject wise list that varies by cadet. It tests detailed knowledge of the aircraft type you trained on, usually a Cessna 152 or 172, a Diamond DA40, or a Piper Seneca or DA42 if you went multi-engine.
The syllabus, derived from the Pilot’s Operating Handbook (POH) of your trainer aircraft, covers:
- Aircraft general: dimensions, weight limits, certification basis.
- Powerplant specifics: engine model, power output, RPM limits, fuel grade.
- Performance: takeoff and landing distances, climb performance, cruise data, range and endurance.
- V-speeds: Vne, Vno, Vfe, Va, Vs, Vx, Vy, and what each does in flight.
- Systems specific to your aircraft: fuel system layout and capacity, electrical schematic, brake and undercarriage systems.
- Emergency procedures: engine failure drills, electrical fire response, alternator failure, landing gear malfunction.
- Limitations: weight, balance, manoeuvring, and operational limits.
The best preparation is the POH itself, read cover to cover at least three times during your ground school. Don’t rely on summary notes for this paper. Examiners often pull questions from sections (servicing intervals, exact fuel capacities) that summary guides skip. If you trained on a multi-engine aircraft, your paper will include additional content on asymmetric flight and engine-out procedures.
RTR(A): the sixth paper now under DGCA
The Radio Telephony Restricted Aeronautical licence, RTR(A), was administered by the Wireless Planning and Coordination Wing under the Department of Telecommunications for decades. Since November 2025, it now sits under DGCA along with the other CPL papers, which means you register for it through the same Computer Number and follow the same Pariksha workflow.
The RTR(A) syllabus and exam structure cover:
- Written test: radio regulations, radio principles (transmission, reception, propagation), VHF operating procedures, and radio telephony rules.
- Practical exam: from January 2026, the practical uses scenario-based simulated flight communication, where you’re given a flight scenario and expected to handle the radio work end-to-end: ATC calls, position reports, emergency calls, weather queries.
- Phraseology: standard ICAO phraseology, callsign rules, distress and urgency signals, readback requirements.
The practical is the part most cadets stumble on, not because the material is hard, but because they haven’t rehearsed live radio work under pressure. Pair up with another cadet and run mock RT sessions twice a week from your ground school’s mid-point. Treat it like a language paper. Fluency only comes with speaking, not with reading.
Subject-wise difficulty: which DGCA CPL papers to clear first
Not every paper deserves equal study time, and the order you attempt them changes how quickly you finish. Here’s a rough difficulty mapping based on what cadets and DGCA coaching institutes consistently report.
| Paper | Difficulty | Best time to attempt | Why |
|---|---|---|---|
| Air Regulations | Medium (memorisation) | First sitting | Builds confidence; rewards focused reading |
| Technical General | Medium (broad recall) | First sitting | Sits well with Air Regs prep style |
| Technical Specific | Easy to Medium | Soon after flight training | POH knowledge is freshest then |
| Aviation Meteorology | Hard (decoding + theory) | Second sitting | Needs daily decoding practice to build speed |
| Air Navigation | Hardest (calculations) | Second or third sitting | CRP-5 fluency takes 8–12 weeks to build |
| RTR(A) | Medium (practical-heavy) | Anytime; bundle with above | Practical needs live RT rehearsal |
A common strategy: clear Air Regulations and Technical General in your first quarterly sitting, take Technical Specific while your trainer aircraft is fresh in your head, then put Navigation and Meteorology in a later sitting after you’ve had two to three months of focused calculation and decoding practice.
The five-year validity window means there’s no rush to bunch everything into one quarter. Cadets who split their attempts strategically often clear all six papers faster than those who try to clear everything in one go and end up re-sitting two.
Step-by-step subject-wise study plan
Here’s how to structure a four-to-six-month prep cycle across the DGCA CPL subjects:
- Weeks 1–2: Foundation. Read the Air Regulations text cover to cover. Set up your CRP-5 and start basic navigation problems (latitude/longitude, time conversions). Start daily METAR decoding (10 reports a day from Indian aerodromes).
- Weeks 3–6: Build the technical base. Move into Technical General, focusing one week each on aerodynamics, engines, electrical, and instruments. Continue Navigation chart work in parallel. Add fronts and weather charts to Meteorology study.
- Weeks 7–10: Subject specifics. Read your trainer aircraft’s POH twice. Start Air Regulations MCQ drilling. Tackle wind triangle and ETP/PNR calculations in Navigation.
- Weeks 11–14: Mock test phase. Do one full mock test per subject per week. Identify weak areas. For each wrong answer, write the correct answer plus a one-line explanation in a revision notebook.
- Weeks 15–18: RTR(A) and final polish. Start RT mock sessions twice a week. Bunch Air Regulations and Technical General into your first Pariksha sitting.
- Post first sitting: Second-round prep. Use the next two months to push Navigation and Meteorology preparation deeper before your second sitting. Practise RTR phraseology daily until your practical date.
Adjust the schedule if you’re juggling flight training abroad or working full-time. The principle stays the same: front-load reading subjects, build the calculation-heavy subjects slowly, and keep mock testing weekly from the midpoint onwards.
Frequently asked questions
Q: How many subjects are in the DGCA CPL syllabus? A: The DGCA CPL syllabus subject wise covers five core papers (Air Navigation, Aviation Meteorology, Air Regulations, Technical General, and Technical Specific) plus the RTR(A) radio telephony paper, which has been under DGCA since November 2025. Each is examined and passed independently at a 70% mark, with no overall aggregate.
Q: Which DGCA CPL subject is the hardest? A: Air Navigation is widely considered the hardest because of its calculation load, with roughly 25 to 30 percent of questions involving numerical work on the CRP-5 flight computer. Aviation Meteorology comes a close second due to its weather chart and METAR/TAF decoding demands. Most cadets clear Air Regulations and Technical General first to build momentum before tackling Navigation.
Q: How long does it take to study the full DGCA CPL syllabus? A: Most cadets cover the full DGCA CPL syllabus in four to six months of focused ground school, with an additional 3 to 5 hours of personal study per day. Fast-track options can compress this to three months, but they only work for cadets with a strong science background. Plan around the quarterly Pariksha calendar rather than a fixed end-date.
Q: Is the RTR(A) paper still separate from DGCA exams? A: No. Since November 2025, RTR(A) has been under DGCA along with the other CPL papers. You register for it through the same Computer Number and Pariksha portal workflow. It still has its own written and practical components, but the regulator is now DGCA, not the WPC.
Q: How are DGCA CPL papers marked? A: Each paper is multiple-choice with 50 to 100 questions depending on the subject, marked at a 70% pass. There is no negative marking, so always attempt every question. Marks aren’t published nationally, so any coaching institute claiming a specific pass-rate percentage should be asked for batch-level evidence before you enrol.
Q: Can I take the DGCA CPL syllabus subjects in any order? A: Yes. You can choose which papers to attempt in each quarterly Pariksha sitting and in what order. A common sequence is Air Regulations and Technical General first, then Technical Specific while your trainer aircraft is fresh, then Aviation Meteorology and Air Navigation after building decoding and calculation speed. Once you clear a paper, the result stays valid for five years.
Final thoughts
The DGCA CPL syllabus subject wise looks intimidating until you break it into pieces. Then it becomes a study plan you can actually execute. Treat Air Regulations and Technical General as reading subjects, Navigation and Meteorology as skills you build over months, Technical Specific as a POH reading exercise, and RTR(A) as a spoken-language paper that needs live rehearsal. Plan around the Pariksha calendar, not around a fixed graduation date.
