The Civil Aviation Authority (CAA) is the statutory corporation which oversees and regulates all aspects of civil aviation in the United Kingdom. Its areas of responsibility include:

  • Supervising the issuing of pilots' licences, testing of equipment, calibrating of navaids, and many other inspections (Civil Aviation Flying Unit).
  • Training of Air Traffic Engineers to maintain airport and en-route telecommunications (CAA College of Telecommunications Engineering).
  • Managing the regulation of security standards, including vetting of all personnel in the aviation industry (Directorate of Aviation Security).
  • Overseeing the national protection scheme for customers abroad in the event of a travel company failure (Air Travel Organisers' Licensing – ATOL).

The CAA is a public corporation of the Department for Transport, liaising with the government via the Standards Group of the Cabinet Office.


The CAA directly or indirectly regulates all aspects of aviation in the UK. In some aspects of aviation it is the primary regulator; in other areas, where the responsibility for regulation has passed to the European Aviation Safety Agency (EASA), the CAA acts as EASA's local office, implementing the regulations. Representatives from the CAA sit on EASA's advisory bodies, taking part in the Europe-wide regulation process.

The UK government requires that the CAA's costs are met entirely from its charges on those whom it regulates. Unlike many other countries, there is no direct government funding of the CAA's work. It is classed as a public corporation, established by statute, in the public sector. The connection it has with the government is via the machinery of government and the Standards Group of the Cabinet Office.


The CAA regulates (approximately):


The CAA also oversees the Air Travel Organisers' Licensing (ATOL).

By law, every UK travel company which sells air holidays and flights is required to hold an ATOL, which stands for Air Travel Organiser's Licence.

If a travel company with an ATOL ceases trading, the ATOL scheme protects customers who had booked holidays with the firm. It ensures they do not get stranded abroad or lose money.

The scheme is designed to reassure customers that their money is safe, and will provide assistance in the event of a travel company failure.


The CAA was established in 1972, under the terms of the Civil Aviation Act 1971, following the recommendations of a government committee chaired by Sir Ronald Edwards.[1] Previously, regulation of aviation was the responsibility of the Air Registration Board. The current main Act of Parliament regulating aviation in the UK is the Civil Aviation Act 1982. Responsibility for air traffic control in the UK passed to NATS in the run-up to the establishment of its public-private partnership in 2001.

From 1 April 2014, the CAA took over a number of aviation security functions from the Department for Transport. The new Directorate of Aviation Security within the CAA now manages rule-making and compliance to deliver proportionate and focussed regulation for UK aviation to ensure the highest standards of security across the civil aviation sector. The CAA also manages all national security vetting for the aviation industry.

Air Safety Support International, a subsidiary of the CAA, is responsible for air safety in the British Overseas Territories.[2]

The CAA head office is located in CAA House on Kingsway in Holborn, London.[3] The CAA Safety Regulation Group is in Aviation House in Gatwick Airport in Crawley, England.[4] The CAA is a public corporation of the Department for Transport.[5]

GA regulation

General aviation is an official category that covers a wide range of unscheduled air activity such as flying clubs and training establishments. In 2013 the CAA announced a new approach to regulating GA which will be more proportionate. A new dedicated GA unit was established in 2014 www.caa.co.uk/ga

CAA Flying Unit

The CAA was also responsible for the calibration of navigation and approach aids until the Flight Calibration Services group was privatised and sold to Flight Precision Ltd in 1996.

The history of the Civil Aviation Flying Unit (CAFU) can be traced back to the Air Ministry's Civil Operations Fleet founded in 1944. The CAA and its predecessors have operated 49 aircraft of 13, primarily British, aircraft types including de Havilland Tiger Moths, Avro Ansons, Airspeed Consuls, Percival Princes, de Havilland Doves,[6] Hawker Siddeley HS 748s[7][8] and Hawker Siddeley HS 125s.[9][10]

The roles performed by CAFU aircraft included:

  • Calibration and testing of radio/radar navigational aids in the UK and overseas
  • Flight testing of candidates for the initial issue of commercial pilots' licences, instrument ratings and instructor ratings
  • Training and testing of authorised instrument and type-rating examiners
  • Carriage of Government Ministers, MEPs and other officials
  • Charter flights for Dan-Air Services Ltd
  • Radar target flying for the College of Air Traffic Control
  • Ordnance Survey photographic flights
  • Airport lighting inspections
  • Aerodrome categorisation and evaluation flights
  • Trials of new equipment and procedures, e.g. Microwave Landing Systems, ground proximity warning systems, Extended Range Twin-engine Operations (ETOPS)
  • Refresher flying for Flight Operations Inspectors and other staff
  • Educational flights for local schools,[11][12][13]

Beyond the privatisation of the calibration service in 1996, the Civil Aviation Authority operated two HS 125-700 aircraft successively up until 2002, providing conversion and continuation flying for professional CAA pilots, conducting radar trials for National Air Traffic Services (NATS) and serving the CAA, NATS and Highlands & Islands Airports Ltd (HIAL) in the communications role.

Previous to the privatisation, Stansted Airport had been the home of Flight Calibration; however, in 1996 the department was moved to Teesside Airport in the North East of England with the photographic laboratory services contracted out to a local company, HighLight Photographics.

CAA Signals Training Establishment (STE) – Bletchley Park

Based mainly in 'A', 'B' and 'E' Blocks and with further Navigation Aid and Radar classrooms on the northwest corner of the park (now occupied by housing), the STE trained technicians to maintain airport and en-route telecommunications and navigational aids for UK airport and en-route services, including telecommunications, navigational aids and radar.

A two-to-three-year locally domiciled apprenticeship trained technicians who were then posted to airports or en-route centres for on-going employment. STE also provided training facilities for existing technicians to keep up to date with technological developments or to enhance their skills on a broader range of equipments.

Apprentices had exclusive use of the 'AT Club' (Apprentice Technicians Club) and also to the Bletchley Park 'Radio Shack' with a call-sign of 'G4BWD' – 'Golf Four Building Works Department', able to access the 2-metre band.

In 1974, STE developed a newer training course, reducing training to a one-to-two-year period for higher-qualified ('A'-level and beyond) entrants, nicknamed 'Super-ATs' or 'Super-Techs'.

CAA College of Telecommunications Engineering (CTE) – Bletchley

In 1975/1976, the 'Signals Training Establishment' was renamed the 'College of Telecommunications Engineering', with 'Apprentice Technicians' being re-badged as 'Engineer Cadets', no longer passing out as 'Radio Technicians' but as 'Air Traffic Engineers'.
