Please note that the "Registration" search will return both registered and de-registered aircraft. The other search fields will only return currently registered aircraft unless the "View de-registered aircraft" box is checked in which case only the de-registered aircraft will be returned. The "Registration" search will retrieve all records that begin with the phrase entered whereas the "Serial Number", "Aircraft Type/Name", "Owner" and "ICAO 24 bit aircraft address (hex)" will return all records containing that phrase. For instance, searching "Owner" with smith might return Paul Smith, Smith and Co and Peter Smithson.

You can also use * as a wildcard. For instance, searching "Aircraft Type/Name" with BEECH 200 will only return BEECH 200, however searching on BEECH*200 will return BEECH 200 and BEECH B200. Data can also be entered in any combination of the search fields to further refine your search.

The "Aircraft type/name" search field simultaneously searches on the manufacturer, full type name, popular name and generic name of the aircraft. If you are unsure of the designation of an aircraft put in the simplest description of the aircraft (generic name), eg PA34 for a Piper PA-34-200T, a single line listing of all examples will appear. From the information displayed you will be able to refine your search to reduce the number of records retrieved.

Alternatively enter the popular name for the aircraft, eg Citation for a Cessna 500, a single line listing of all examples will appear. From the information displayed you will be able to refine your search to reduce the number of records retrieved.

The "ICAO 24 bit aircraft address (hex)" searches on the hexadecimal version of the ICAO 24 bit aircraft address. This address is used for various purposes including Mode S transponders and emergency locator transmitter equipment.
