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.

The AvStats user guide explains how to use the system and submit data.

You will need to use the new AvStats templates when you make a data submission.

There are guidance notes for each form that explain;

  • the data that needs to be input in each column
  • how the data should be formatted/presented

When submitting data there are a number of mandatory fields and these have been highlighted on the templates provided.

Fields requiring prescribed values are case sensitive - in the template, headings show the permitted values parenthesised and in the appropriate case.

You can submit data in one of three file formats; CSV, XLSX or (for certain forms) XLM.

The time required to process your data will vary depending on submission size and could take up to one hour.

The AvStats system will time out if there has been no activity after two hours.

Make sure you download the latest valid reporting codes using the links below.

Please be aware that the ICAO and IATA codes in our reference lists may not always correspond to those published in other sources. It is important that you use the codes published on this website as they will be the ones that AvStats will accept

For Airline Quarterly Hours And Flights Suppliers please remember that the field "Aircraft Code Type (ICAO)" (Column D) should just contain the text “ICAO” and not the aircraft code itself.

Please see our guidance notes for more information.

Reporting on cancelled flights

Aircraft registrations

Aircraft registration is a mandatory field and the system will require a response for this field to enable an initial load and system verification.

If no code exists in your own records then please enter any registration that matches the aircraft type and operator being reported.

Please do not use generic “XXX” codes.

AvStats uses a lookup to the UK register which checks that the registration matches the aircraft type being reported and is owned by the Operator shown. We will be in touch once a permanent solution has been found.

Reporting on airport terminals

Please report a terminal building how it is known at the airport.

LGW have the North Terminal and South Terminal. For anything else please report as 1.

For example, Sumburgh Airport, with ONE terminal would be recorded as Terminal = 1.

Rejected data

If your file is rejected with the reason “Invalid File Format” it is possible that the headings in your file have been changed.

We’d recommend that you download a new template and paste your data into it without changing the header row.
