How to Study DGCA Air Regulations: A Topic Map to the Real Source Documents (2026)
Air Regulations frustrates many DGCA CPL students because it feels like a long list of rules to memorise. It is easier than that. Almost every topic in the syllabus comes from a small number of source documents. Once you know which document a topic comes from, you know where to look, how the rule is worded and why it exists.
This guide maps the official CPL Air Regulation syllabus to its sources. It also explains a change many study materials haven't caught up with: India's main aviation law changed on 1 January 2025, and the rules made under it are being replaced.
Important 2026 update: the law is changing
The current DGCA CPL Air Regulation syllabus was issued in 2011. It still lists the Aircraft Act 1934 and the Aircraft Rules 1937 under "National law". Here is what has happened since:
1 January 2025: the Bharatiya Vayuyan Adhiniyam, 2024 came into force and replaced the Aircraft Act 1934. Section 43 of the new Act keeps existing rules, licences, approvals and orders in force as long as they are not inconsistent with it.
July 2025: the Ministry of Civil Aviation published the draft Bharatiya Vayuyan Niyam, 2025. These draft rules propose repealing the Aircraft Rules 1937, Part IX of the Aircraft Rules 1920, and other rules.
August 2026: while hearing a petition about airfares, the Supreme Court gave the government three weeks to finalise the rules.
16 October 2026: the government told the Supreme Court that the rules had been finalised and approved, and would be published within two weeks.
What this means for your exam (as of 17 October 2026): DGCA's examination guidance still states that flight-crew exams are held under Rule 41A of the Aircraft Rules 1937, so the 1937 Rules remain the framework for now. Most Air Regulations content comes from ICAO standards, which don't change when Indian law is renumbered. The parts most likely to change are the national law items: rule numbers, licence requirements and penalties. Check DGCA and the Ministry of Civil Aviation for the final notified rules, and don't rely on old notes alone.
Where Air Regulations come from
Think of aviation regulation as a ladder. Each rung puts the one above it into practice:
The Chicago Convention (1944) created ICAO and obliges member states to follow its standards as far as practicable.
The ICAO Annexes (1 to 19) contain the Standards and Recommended Practices (SARPs).
PANS and other ICAO Docs give detailed procedures, for example Doc 4444 for air traffic management and Doc 8168 for aircraft operations (PANS-OPS).
India's Act, now the Bharatiya Vayuyan Adhiniyam 2024, gives the government power to make rules.
Rules made under the Act, currently the Aircraft Rules 1937 and other rules.
DGCA's Civil Aviation Requirements (CARs) set out the detailed requirements.
AIP India, AICs and NOTAMs, published by the Airports Authority of India's aeronautical information service, give the operational detail.
When India departs from an ICAO standard, the difference is published in AIP India, section GEN 1.7. Syllabus item 1.15 specifically asks about national law "and differences to relevant ICAO Annexes and CARs", so GEN 1.7 is worth reading.
The syllabus-to-source map
The CPL Air Regulation syllabus (CAR Section 7, Series B, Part IV, Appendix C) has 15 main items. Here is where each one comes from:
Syllabus item | Topic | Primary source | Indian layer |
1.1 | International agreements and organisations | Chicago Convention; Warsaw, Tokyo, Hague and Montreal conventions | DGCA's organisation; the Act |
1.2 | Airworthiness of aircraft | ICAO Annex 8 | CAR Section 2 |
1.3 | Nationality and registration marks | ICAO Annex 7 | Aircraft Rules (registration and marking) |
1.4 | Personnel licensing | ICAO Annex 1 | CAR Section 7; Aircraft Rules Schedule II |
1.5 | Rules of the air | ICAO Annex 2 | AIP India ENR 1 |
1.6 | Procedures for air navigation: aircraft operations | ICAO Doc 8168 Vol I; Doc 7030 | AIP India procedures |
1.7 | Air traffic services | ICAO Annex 11; Doc 4444; Doc 7030 | AIP India GEN 3.3, ENR 1–3 |
1.8 | Aeronautical information service | ICAO Annex 15 | AIP India itself |
1.9 | Aerodromes | ICAO Annex 14 | CAR Section 4 |
1.10 | Facilitation | ICAO Annex 9 | — |
1.11 | Search and rescue | ICAO Annex 12 | AIP India GEN 3.6 |
1.12 | Security | ICAO Annex 17 | — |
1.13 | Aircraft accident investigation | ICAO Annex 13 | Aircraft (Investigation of Accidents and Incidents) Rules 2025 |
1.14 | CARs | — | CAR Sections 2, 7 and 8 |
1.15 | National law | — | The Act, Aircraft Rules and other listed rules |
The accident investigation rules have already changed. The Ministry of Civil Aviation notified the Aircraft (Investigation of Accidents and Incidents) Rules, 2025 under the new Act, replacing the 2017 Rules made under the Aircraft Act 1934.
The ICAO Annexes you need to know by number
Exam questions often test which Annex covers what. Thirteen of the nineteen Annexes appear in the Air Regulations syllabus. Annexes 1, 2, 7, 8, 9, 11, 12, 13, 14, 15 and 17 appear directly; Annexes 6 and 18 appear in the operational procedures section of the same appendix.
A useful way to remember them is in groups:
People and aircraft: 1 (licensing), 7 (registration), 8 (airworthiness).
Flying: 2 (rules of the air), 6 (operation of aircraft), 11 (ATS), 15 (AIS).
Ground and emergencies: 9 (facilitation), 12 (SAR), 13 (accident investigation), 14 (aerodromes), 17 (security), 18 (dangerous goods).
DGCA's Civil Aviation Requirements
DGCA publishes CARs in sections. Each section is divided into Series and Parts. The syllabus names Sections 2, 7 and 8.
The CPL syllabus itself is a CAR: Section 7, Series B, Part IV. Reading it directly is the quickest way to see exactly what DGCA expects you to know.
Finding your way around AIP India
AIP India follows the ICAO format: GEN (general), ENR (en route) and AD (aerodromes). For Air Regulations, the most useful sections are:
GEN 1.7: differences from ICAO standards.
GEN 3.3 and GEN 3.6: air traffic services, and search and rescue.
ENR 1 to ENR 3: general rules, ATS airspace and routes.
ENR 5: prohibited, restricted and danger areas.
AD 2: information on individual aerodromes, with charts under AD 2.24.
Always use the edition currently in effect, and check supplements and NOTAMs.
International agreements: freedoms and conventions
The five freedoms of the air
Freedom | Right |
1st | Fly over another state without landing |
2nd | Land in another state for non-traffic purposes (fuel, maintenance) |
3rd | Carry traffic from your home state to another state |
4th | Carry traffic from another state to your home state |
5th | Carry traffic between two foreign states, on a service starting or ending in your home state |
The first two freedoms come from the International Air Services Transit Agreement. All five appear in the International Air Transport Agreement, which the syllabus calls "the five freedoms". Both were signed at Chicago in 1944.
The conventions in the syllabus
A memory hook: Tokyo = on board (offences and the commander's powers), Hague = hijack (unlawful seizure), Montreal 1971 = sabotage (unlawful acts against safety). Warsaw and Montreal 1999 deal with an air carrier's liability, not security.
Worked example: tracing a question to its source
Question: An aircraft has been cleared to land but fails to land within five minutes of its estimated landing time, and communication cannot be re-established. Which emergency phase applies?
Syllabus item: 1.7, Air Traffic Services, "Alerting service".
Source: ICAO Annex 11, Chapter 5 (Alerting service).
Answer: the alert phase (ALERFA).
Indian layer: AIP India GEN 3.6 for search and rescue arrangements.
Answering from the source means you also learn the surrounding rules. Here, that includes the 30-minute uncertainty triggers, and the distress triggers of fuel considered exhausted or a forced landing. Related questions are then much easier.

Note the Indian layer: CARs, AIP India and GEN 1.7 differences.
Write your own questions from the source text.
Test yourself with practice papers, then go back to the source for anything you got wrong.
Common mistakes
Mistake | Fix |
Saying the Aircraft Act 1934 is still in force | It was replaced by the Bharatiya Vayuyan Adhiniyam 2024 on 1 January 2025. |
Assuming the Aircraft Rules 1937 have been repealed | As of 17 October 2026 they still apply. The replacement rules are finalised but not yet published. |
Mixing up Annexes 7 and 8 | 7 = nationality and registration marks. 8 = airworthiness. |
Confusing Tokyo, Hague and Montreal | Tokyo = on board, Hague = hijack, Montreal 1971 = sabotage. |
Confusing the 2nd and 5th freedoms | The 2nd is a technical stop with no traffic. The 5th carries traffic between two foreign states. |
Learning only from question banks | Questions without their source teach you answers, not rules. Trace each one back. |
Ignoring national differences | Read AIP India GEN 1.7. Syllabus item 1.15 asks about it. |

FAQs
Is the Aircraft Act 1934 still in the DGCA syllabus?
The 2011 syllabus document still lists it, but the Act itself was replaced on 1 January 2025. Know what replaced it and when, learn the core content, and check DGCA's current guidance for any syllabus revision.
Have the Aircraft Rules 1937 been replaced?
Not yet, as of 17 October 2026. The government told the Supreme Court on 16 October 2026 that new rules had been finalised and would be published within two weeks. DGCA's exam guidance still refers to Rule 41A of the 1937 Rules.
Do I need to read every ICAO Annex in full?
No. Use the syllabus to target the chapters it names, such as definitions, applicability and specific procedures, and read those sections properly.
What is the difference between a CAR and the Aircraft Rules?
Rules are made by the central government under the Act. CARs are detailed requirements issued by DGCA under the powers those rules give it.
Why does AIP India matter for a theory exam?
It is where ICAO standards meet Indian practice. The syllabus refers to it directly (items 1.8 and 1.15), and GEN 1.7 lists India's differences from ICAO.
