Quick reference

National legislation: Aircraft Act 1934 and Aircraft Rules 1937

  • Aircraft Act 1934 (Act XXII of 1934) is the parent statute; its preamble covers control of the manufacture, possession, use, operation, sale, import and export of aircraft.

  • The Act applies to the whole of India and, for Indian-registered aircraft, is extra-territorial in effect; foreign aircraft are covered while within Indian territory.

  • Aircraft Rules 1937 are subordinate legislation made by the Central Government under the Act and carry the operational detail: registration, airworthiness, licensing, rules of the air and aerodromes.

  • Hierarchy of norms: Act > Rules > Civil Aviation Requirements (CARs) issued by DGCA > circulars and AIP; a CAR cannot override the Rules.

  • Rule 3 of the Aircraft Rules 1937 is the definitions rule; 'aircraft', 'aerodrome', 'accident', 'incident' and related terms are defined there and govern the later parts of the Rules.

  • Institutional split: DGCA is the licensing, airworthiness and operational regulator; BCAS handles aviation security; AAIB investigates accidents; AERA regulates airport tariffs under the AERA Act 2008.

  • Aircraft (Amendment) Act 2020 gave statutory status to the AAIB (with statutory backing for DGCA and BCAS) and substantially enhanced penalties for contraventions.

  • Indian civil aircraft carry the nationality mark 'VT' followed by a group of letters (for example VT-ABC), entered in the DGCA register of aircraft.

International air law: Chicago Convention, ICAO Annexes, bilateral agreements

  • Chicago Convention 1944 (ICAO Doc 7300) has 96 articles and 19 annexes; Article 1 gives each State complete and exclusive sovereignty over the airspace above its territory.

  • Article 3: the Convention applies to civil aircraft only; state aircraft (military, customs, police) may not fly over or land in another State without special permission.

  • Articles 5 and 6: non-scheduled flights have a right of transit and non-traffic stop subject to State conditions, while scheduled international air services need special permission, normally a bilateral air services agreement.

  • Article 7 (cabotage): a State may refuse a foreign carrier the right to take on traffic for reward between two points within its own territory.

  • Article 12: over the high seas the ICAO rules of the air apply without exception; each State must apply them to its own aircraft wherever they fly.

  • Article 29 lists the documents carried on board: certificate of registration, certificate of airworthiness, crew licences, journey logbook, radio station licence, passenger list and cargo manifest.

  • Articles 32 and 33: licences and certificates are issued or validated by the State of registry and must be recognised by other States if they meet or exceed ICAO minimum standards.

  • Article 38: a State unable to comply with an International Standard must notify ICAO of the difference; Recommended Practices are desirable but not mandatory.

  • Article 90: Annexes are adopted by a two-thirds vote of the ICAO Council and take effect in about three months unless a majority of States disapprove; Article 94 amendments need two-thirds of the Assembly and ratification by two-thirds of States.

  • Nine freedoms exist; bilateral agreements commonly grant 1st/2nd (overflight and technical stop), 3rd/4th (own-country traffic) and sometimes 5th freedom (traffic between two foreign points), while 6th to 9th freedoms are rarely granted.

Personnel licensing, flight crew privileges and ratings

  • ICAO Annex 1 defines the licences (PPL, CPL, MPL, ATPL) plus ratings - type or class, instrument, instructor and examiner - together with medical and language-proficiency requirements.

  • ICAO minimum experience: PPL 40 hours, CPL 200 hours (150 hours in an approved course), ATPL 1,500 hours; minimum ages are 17, 18 and 21 respectively.

  • In India, flight crew licences are issued by DGCA under CAR Section 7 after written examinations, a skill test with an approved examiner and the appropriate medical assessment.

  • Privileges: the ATPL holder may act as pilot-in-command and as co-pilot in commercial air transport; the CPL holder may act as pilot-in-command in non-commercial operations and as co-pilot in commercial air transport.

  • A type rating is required for each multi-pilot or multi-engine type; a class rating covers single-engine aeroplanes; an instrument rating is required to fly IFR in controlled airspace.

  • Recency: three take-offs and three landings within the preceding 90 days (at night for night passenger carriage) before carrying passengers.

  • Medical: Class 1 for CPL/ATPL, Class 2 for PPL; Class 1 validity is normally 12 months, shortened in defined cases such as older pilots in single-pilot commercial operations.

  • English language proficiency at ICAO Level 4 or better is required and is endorsed on the licence with an expiry date.

Airworthiness, maintenance and continuing airworthiness requirements

  • No aircraft may fly unless it holds a valid certificate of airworthiness issued by DGCA and is maintained in accordance with an approved maintenance programme.

  • Type certification: an imported aircraft requires DGCA type acceptance or validation, and modifications or repairs require approved design data before fitment.

  • Airworthiness Directives are mandatory; compliance must be recorded within the stated times, and the aircraft is not airworthy until the directive is embodied.

  • Indian continuing airworthiness structure: CAR 145 for approved maintenance organisations, CAR M for continuing airworthiness management, CAR 66 for certifying staff and CAR 147 for training organisations.

  • A Certificate of Release to Service must be issued after maintenance and before flight; work outside the scope of the approval cannot be released.

  • The MEL, derived from the master MEL with DGCA approval, permits dispatch with specified defects under stated conditions; a defect not in the MEL must be rectified before flight, and the CDL covers missing items.

  • Records - logbooks, task records, AD and service-bulletin status, mass and balance data - must be kept and made available to DGCA on request.

  • The certificate of airworthiness lapses on expiry, on failure to comply with maintenance or ADs, or after major damage; DGCA may suspend or revoke it where safety is affected.

Air operations: AOC, operating procedures, flight and duty time limitations

  • An Air Operator Certificate is issued by DGCA under the Aircraft Rules 1937 and CAR Section 3 after assessment of organisation, aircraft, manuals, training and proving flights.

  • The operator must hold DGCA-approved operations manual, MEL, training programme and a safety management system, with documented quality and occurrence-reporting processes.

  • The flight and duty time limitation scheme under CAR Section 7 Series J must be approved and reflected in rosters; records of flight time, duty and rest are retained.

  • Flight time limits: 8 hours in any 24 hours for a two-pilot crew (9 hours with three pilots, 10 hours with four), 100 hours in 30 consecutive days and 1,000 hours in 365 days.

  • Fuel policy: taxi, trip, contingency, destination alternate where required, and final reserve - 30 minutes holding at 1,500 ft for turbine aeroplanes, 45 minutes for piston aeroplanes.

  • Take-off, landing and alternate minima must be published in the operations manual; descent below minima requires the specified visual reference, otherwise a go-around or diversion follows.

  • Before flight the operator must complete the load sheet, confirm mass and balance limits, and ensure passengers are briefed on emergency equipment and procedures.

  • Occurrences, accidents and serious incidents must be reported under the mandatory occurrence reporting scheme and to AAIB/DGCA as applicable.

Rules of the air and air traffic services

  • India applies ICAO Annex 2 through the Aircraft Rules 1937 and the AIP; an ATC clearance does not relieve the pilot-in-command of responsibility for compliance and safe separation from terrain.

  • Right of way: converging aircraft - the one with the other on its right gives way; head-on - both turn right; overtaking - the overtaken aircraft has right of way and is passed on the right.

  • Landing: an aircraft on final approach or landing has right of way over aircraft on the ground; the lower aircraft has right of way but must not cut in ahead of another on final.

  • Semicircular cruising levels: magnetic track 000–179° uses odd thousands, 180–359° even thousands; VFR adds 500 ft; the transition altitude in India is generally 4,000 ft.

  • Speed: 250 kt IAS below 10,000 ft in airspace classes C to F unless ATC authorises otherwise; ATC may impose lower speeds.

  • SSR codes: 7500 unlawful interference, 7600 radio communication failure, 7700 general emergency.

  • Vertical separation: 1,000 ft below FL290; 2,000 ft at and above FL290 without RVSM; 1,000 ft within the RVSM band FL290–FL410.

  • Emergency: the pilot-in-command may deviate from the rules to the extent necessary, must inform ATC as soon as practicable and submit a report afterwards.

  • Airspace classes A to G: Class A is IFR only with all aircraft separated; Class C separates IFR from VFR and VFR from VFR; Class G is uncontrolled with no separation service.

Accident and incident investigation and reporting

  • Annex 13: the State of Occurrence institutes the investigation; the States of Registry, Operator, Design and Manufacture may appoint accredited representatives.

  • Accident: an occurrence between boarding and disembarking in which a person is killed or seriously injured, the aircraft sustains substantial damage or structural failure, or the aircraft is missing or inaccessible.

  • Serious injury: an injury requiring hospitalisation for more than 48 hours, starting within seven days of the injury, or involving fracture, serious laceration or comparable damage.

  • Incident: an occurrence, other than an accident, associated with the operation of an aircraft that affects or could affect the safety of operations.

  • In India the AAIB, statutory since 2020 and independent of DGCA, investigates accidents and serious incidents; the sole objective is prevention, not apportioning blame.

  • The State of Occurrence notifies ICAO of accidents involving aircraft over 2,250 kg maximum mass and sends a preliminary report within 30 days of the accident.

  • Flight recorders are protected and read out at approved facilities; cockpit voice recorder content is not used for disciplinary purposes except where safety requires.

  • Mandatory occurrence reporting by operators and pilots supplements accident reporting and feeds safety recommendations to regulators and operators.

Aviation security, dangerous goods, facilitation and environmental rules

  • Annex 17: each State establishes a civil aviation security programme; India's NCASP is administered by BCAS, with airport security provided through the aviation security group arrangements.

  • Security measures include screening of passengers, cabin and hold baggage, cargo and mail, access control to security restricted areas, and protection of aircraft and navigation facilities.

  • Annex 18 and the ICAO Technical Instructions govern dangerous goods; the operator needs a dangerous goods manual and training programme, and the shipper signs a Shipper's Declaration.

  • Dangerous goods classes: 1 explosives, 2 gases, 3 flammable liquids, 4 flammable solids, 5 oxidisers and organic peroxides, 6 toxic and infectious substances, 7 radioactive, 8 corrosive, 9 miscellaneous including lithium batteries.

  • Hidden dangerous goods must be declared by the shipper; items such as certain lithium batteries, matches, self-heating substances and aerosols are restricted or forbidden in baggage.

  • Annex 9 (Facilitation) sets standards for clearance of aircraft, passengers and cargo at borders while preserving effective customs, immigration, health and quarantine controls.

  • Annex 16 Volume I covers aircraft noise certification (chapters by aircraft type), Volume II engine emissions, Volume III CO2 certification and Volume IV the CORSIA offsetting scheme.

  • Indian-registered aircraft must meet the applicable noise certification requirements and operators must hold noise documentation and follow airport noise abatement procedures.
