Air Operator Certificate (AOC)

The certificate an operator needs to fly commercial air transport or public transport. A genuine cost-shared flight does not need one.

Also called: AOC, Air Operator's Certificate

CAP 1590 (guidance), para 5 states:

If a flight is CAT or PT, the operator must have an Air Operator’s Certificate (AOC); the pilot must hold at least a Commercial Pilot’s Licence (CPL); and the aircraft must be certificated and maintained in accordance with the appropriate airworthiness requirements.

The cost sharing rules exist so that private pilots can share the direct costs of a flight without any of that. A flight that meets NCO.GEN.102 (Part-21 aircraft) or ANO 2016 art. 13 (non-Part-21 aircraft) is treated as non-commercial, so no AOC is needed.

If the conditions are not met, for example because passengers pay more than their equal share or the flight is run by a company, the flight falls back into CAT or PT. The ANO lists the related offences in Schedule 13 Part 3:

Article Subject matter
101(1) Aircraft not to fly for public transport without AOC
103 Aircraft not to fly on a commercial air transport operation except under a Part-CAT AOC
104(1) Offering commercial air transport and public transport flights without AOC

Offences in Part 3 are punishable under ANO art. 265(7), and art. 265(1) deems both the operator and the pilot in command to have contravened a provision broken in relation to an aircraft. See cost sharing vs charter for where the line sits.
