UK Civil Aviation Regulations

These are published by the CAA on our UK Regulations pages. EU Regulations and EASA Access Guides published by EASA no longer apply in the UK. Our website and publications are being reviewed to update all references. Any references to EU law and EASA Access guides should be disregarded and where applicable the equivalent UK versions referred to instead.



Before you apply for an AOC it is essential that you understand what type of AOC you need.

You should consider:

  • the types of aircraft you intend to operate
  • what area and routes you wish to fly
  • whether you need an all weather operation or one which is limited to flights by day, or by night only

Types of Air Operator Certificate (AOC)

A to B AOC

Also referred to as a "full" AOC, it enables operators to fly from point A to point B. The conditions attached to a full AOC will be determined by the competence and ambitions of the organisation.

  • The AOC operating area may restrict flights to remain within the UK, or may permit operations to the near continent or be fully global.
  • Operations may be conducted in all weather, or may be restricted to day only, day and night under Visual Flight Rules (VFR).
  • Flights may be run as scheduled services, or as ad hoc charter.
  • An operating licence is required.

  • Flights must be day VFR only.
  • Only applicable to aircraft not exceeding 5,000 kg Maximum Take-Off Weight (MTOW).
  • Flights are restricted in radius of operation of not more than 50 nautical miles (aeroplanes) or 25 nautical miles (helicopters) from the aerodrome. Application to operate outside of this area may be considered and is likely to incur additional costs.

PAOC - Police Air Operator's Certificate

A specialist National AOC granted to organisations operating in the Service of a Chief of Police.

This AOC requires similar procedures to those of the full AOC; however the very nature of police operations necessitates the provision of 'easements' from the standard regulations.

AOC charges

The CAA charges for an AOC. The cost of an AOC is based upon the type and weight of aircraft you intend to operate.

The charge for the initial issue of an AOC is determined by the planned scope and scale of the operation.
See the CAA Scheme of Charges – Air Operator and Police Air Operator Certificates for more details.

There is no charge for the AOC Application pre-meeting.
