The CAA's regulatory policy work has four core functions:
- economic regulation of the two designated airports (Heathrow and Gatwick) and NATS;
- enforcement of consumer legislation - for example, to protect consumers in instances of flight cancellation and denied boarding, and protect people of reduced mobility when they fly;
- providing expert policy and economic advice and analysis across CAA, to government and others on airports, airlines and air traffic services; and
- collecting and analysing aviation statistics and survey responses.
