Civil Aviation Act 1990

The primary New Zealand statute establishing the Civil Aviation Authority, the Minister's powers, and the legal basis for making Civil Aviation Rules. It sets out offences, enforcement powers, and safety obligations applying to pilots and operators.

Civil Aviation Rules (CARs)

The subordinate legislation made under the Civil Aviation Act, numbered by Part (for example Part 91, Part 61, Part 121). Each Part prescribes binding requirements for operations, licensing, airworthiness, or airspace use.

Related: Civil Aviation Act 1990, Advisory Circular
Advisory Circular (AC)

Non-binding guidance published by the CAA explaining an acceptable means of complying with a Civil Aviation Rule. Following an AC is one way to show compliance but is not itself a legal requirement.

Related: Civil Aviation Rules
Part 91

The Civil Aviation Rule Part containing general operating and flight rules that apply to most aircraft operations in New Zealand unless a more specific Part overrides them. It covers pre-flight, in-flight, and emergency requirements.

Related: Part 61, Part 121
Part 61

The Civil Aviation Rule Part governing pilot licences and ratings, including eligibility, experience, flight-test, and currency requirements for CPL, PPL, and associated ratings such as instrument and instructor ratings.

Related: Commercial Pilot Licence, Medical certificate
Part 121

The Civil Aviation Rule Part for air operations by large aeroplanes (above a specified passenger or weight threshold) in regular air transport. It imposes stricter crew, training, and operational control requirements than Part 91.

Related: Part 91, Air operator certificate
Air operator certificate (AOC)

A certificate issued by the CAA authorising an operator to conduct specified air operations, subject to the operator's exposition, training, and safety-management arrangements meeting the relevant Civil Aviation Rule Part.

Related: Part 121, Exposition
Exposition

A documented set of procedures, policies, and instructions describing how an operator or certificate holder conducts its activities in compliance with its Civil Aviation Rule Part. It forms the basis of CAA certification and ongoing oversight.

Related: Air operator certificate, Part 121
Commercial Pilot Licence (CPL)

A pilot licence permitting the holder to act as pilot in command of aircraft in commercial operations and to receive remuneration, subject to the privileges, ratings, and currency requirements set out in Part 61.

Related: Part 61, Medical certificate
Medical certificate

A document issued by a CAA-approved medical examiner confirming the holder meets the health standards for the licence or rating held. Its class and validity period depend on the privileges being exercised.

Related: Commercial Pilot Licence, Currency
Currency

The requirement that a pilot has completed specified recent experience, such as take-offs, landings, or instrument approaches within a defined period, before exercising particular privileges. Lapse may require a check flight.

Related: Medical certificate, Part 61
Rating

An authorisation added to a pilot licence permitting specified additional privileges, such as an aircraft type rating, instrument rating, or instructor rating. Each rating has its own eligibility and renewal requirements.

Related: Commercial Pilot Licence, Currency
Certificate of airworthiness (C of A)

A certificate confirming that an aircraft conforms to an approved type design and is in a condition for safe operation. It remains valid only while maintenance and airworthiness requirements continue to be met.

Related: Maintenance control, Airworthiness directive
Airworthiness directive (AD)

A mandatory instruction issued to correct an unsafe condition on aircraft of a particular type. Compliance is required within the stated timeframe for the aircraft to remain airworthy.

Related: Certificate of airworthiness (C of A), Maintenance control
Maintenance control

The system and personnel responsible for planning, recording, and certifying maintenance so that an aircraft remains airworthy. It tracks scheduled inspections, defects, and directives, and releases aircraft to service after maintenance.

Related: Airworthiness directive, Certificate of airworthiness (C of A)
Logbook

A record in which a pilot or aircraft owner records flight time, maintenance, and defects as required. It provides evidence of experience for licence purposes and of airworthiness compliance for the aircraft.

Related: Currency, Maintenance control
Controlled airspace

Airspace of defined dimensions within which air traffic control service is provided and in which some or all aircraft require an ATC clearance. It is classified into classes A to E with differing rules and requirements.

Related: Special use airspace, Clearance
Special use airspace

Airspace designated for activities that restrict or prohibit other traffic, such as military operating areas, restricted areas, or danger areas. Pilots must check status and comply with any access conditions before entering.

Related: Controlled airspace, Mandatory broadcast zone
Mandatory broadcast zone (MBZ)

Airspace in which pilots must make specified position and intention radio broadcasts on the designated frequency, whether or not a control service is provided. It improves traffic awareness in areas of higher activity.

Related: Special use airspace, Unicom
Clearance

An authorisation from air traffic control for an aircraft to proceed under specified conditions. It does not relieve the pilot in command of responsibility for terrain clearance, wake turbulence separation, or safe operation.

Related: Controlled airspace, Readback
Readback

The pilot's repetition of safety-related elements of an ATC clearance, such as altitude, heading, frequency, and route, to confirm correct understanding. It is required for clearances and amended instructions.

Related: Clearance, Squawk code
Squawk code

A four-digit code set in the aircraft transponder to identify the aircraft on secondary surveillance radar. Codes may be assigned by ATC or selected from prescribed special-purpose codes.

Related: Readback, Clearance
Unicom

A designated radio frequency used for position broadcasts and traffic coordination at aerodromes without a control tower. Pilots use it to announce intentions and build situational awareness with other traffic.

Related: Mandatory broadcast zone, Aerodrome traffic circuit
Aerodrome traffic circuit

The prescribed pattern of flight around an aerodrome used for arrivals and departures, with specified legs and turn directions. Pilots must conform to the published circuit direction and report positions as required.

Related: Unicom, Right of way
Right of way

The rules determining which aircraft has priority when converging, such as the lower aircraft giving way and aircraft on the right having priority. Aircraft in distress and landing aircraft have special priority.

Related: Collision avoidance, Aerodrome traffic circuit
Collision avoidance

The pilot's duty to maintain a vigilant lookout and take action to avoid other aircraft, regardless of any clearance or traffic information received. It includes using see-and-avoid techniques and onboard traffic alerts.
