Aviation statistics are collated from various sources and published by the Department for Transport (DfT) in a number of compendium publications. Sources include the Civil Aviation Authority (CAA) and the UK Airprox Board.
Information is collected from UK airports and UK airlines by the Civil Aviation Authority (CAA). The CAA is the UK's specialist aviation regulator and publishes a range of information on UK airlines, airports and punctuality. Statistics are published on the CAA website.
An AIRPROX is a situation in which, in the opinion of a pilot or controller, the distance between aircraft as well as their relative positions and speed have been such that the safety of the aircraft was or may have been compromised. AIRPROX can occur between various combinations of commercial, military and private aircraft.

Air transport movements other than scheduled services.
All revenue and non-revenue travellers on air transport movement flights.
Those performed according to a published timetable, including those supplementary thereto, available for use by members of the public.
All travellers joining or leaving an aircraft. A passenger travelling on a domestic flight (between two reporting UK airports) is counted twice, once at each airport. A passenger who changes from one aircraft to another, carrying the same flight number is treated as a terminal passenger, as is an interlining passenger.
Travellers who arrive and depart at an airport on the same aircraft. Each transit passenger is counted once only and not both on arrival and on departure.
