The registration status can either be Registered or De-Registered. If the status is de-registered please note that any details relating to ownership will be as they were at the date of de-registration and no updating will occur beyond that date.

Reason

If the aircraft is de-registered the de-registration reason is given, if the record is blank it means that the historical record concerned is not yet computerised. The reason for de-registration, along with other information can be found on a copy of the historical register entry for the aircraft, please see View Registration History.

Current reg date

This is the date the aircraft was registered to the registered owner displayed on the particular record. This is not necessarily the date of first entry on the Register, please see View Registration History for earlier entries.

De-reg date

This is the date the registration under this mark was cancelled.

To

If the mark is de-registered comments about the subsequent fate of the aircraft are entered here.

Registration

This the nationality and registration mark that was valid during the date ranges specified.

Reference

Issue date

This the date the particular registration entry was valid from.

End date

This is either the change of registered ownership date or the de-registration date for the particular registration entry.

Ownership status

This indicates whether the individual aircraft was registered to the current registered owner as owned or as chartered by demise. The information is applicable to this entry as at the End Date for the particular entry.

Registered owners

This is the registered owner(s) for the individual aircraft as at the End Date for the particular entry according to the information supplied to, and maintained by, the CAA. Please note that the UK Register of Civil Aircraft is not a register of legal ownership, and registration does not confirm legal title.

Notes

This indicates the reason for the change to this particular register entry as at the End Date.

Pre 1986

If historical Register entries are available they will be displayed here as a link to a separate PDF document.

Manufacturer

This is the full title of the manufacturer of the individual aircraft.

ICAO 24 bit aircraft address

The ICAO 24 bit address allocated to the aircraft. Binary, hexadecimal and octal versions are shown.

This address is used for various purposes such as Mode S transponders and emergency locator transmitter equipment. The existence of an address for a specific aircraft does not mean that the aircraft is actually fitted with any equipment that uses the address.

If an aircraft owner or operator intends to use this address on a transponder or ELT please refer to ICAO 24-bit aircraft addresses.

ICAO aircraft type designator

This is a two, three or four-character alphanumeric code for those aircraft types which are most commonly provided with air traffic service (ATS) as issued by ICAO, see ICAO document 8643 for details.

Insurance evidence verified date

If the CAA has requested details of the insurance on a particular aircraft, this date confirms when the details were verified as being in accordance with Article 6 of the Civil Aviation (Insurance) Regulations 2005 and Assimilated Regulation (EU) 785/2004, or no information is available this will display "No Details". If the field is blank, this is because the "No flight" declaration has been made. See below.

Date of "no flight" declaration

If an aircraft is not currently insured and the registered owner has made a declaration to the CAA that the aircraft will not be flown until evidence of insurance has been supplied to the CAA, the date of the declaration is displayed here. If no declaration has been received then "No Details" will be displayed.

If the field is blank this is because the insurance details have been verified, see above.

Maximum (declared or maximum passengers carried)

Either the design maximum number of passengers for the aircraft type or the maximum number of passengers carried as declared by the operator or air carrier.

Additionally, the design maximum number of passengers for hot air balloons is based on a calculation using the notional per person weight of 96kg as the type certificates for hot air balloons do not specify an exact maximum number of passengers. As such, the calculation may over or underestimate the actual maximum number of passengers carried in some circumstances.

Maximum (take-off mass)

This is synonymous with the maximum take off weight authorised (in kilograms) for the individual aircraft. Some data may not have been verified by the CAA.

Exchange rate

The exchange rate from Special Drawing Rights (SDR) to Pounds Sterling (GBP) as taken from the International Monetary Fund website. In cases where insurance details have been provided to the CAA in currencies other than Pounds Sterling the estimate is given in the relevant currency.

Exchange rate (effective date)

The date the exchange date referred to above was last updated, the details are taken from the IMF website.

Minimum cover (combined single limit) for non-commercial operations

As there are different levels of cover required depending on whether the aircraft is used for commercial or non-commercial operations two separate estimates are included.

It should be noted that the estimate is based on a calculation which takes into account the following variable items:

• The maximum take-off mass of the aircraft - taken from the details held by the CAA from the aircraft's flight manual or from another CAA derived source.
• The number of passengers carried - either the number declared by the operator or air carrier (if supplied), or the design maximum number of passengers for the aircraft.
• The exchange rate from SDR's (Special Drawing Rights) to Pounds Sterling taken from the IMF website on the date given.

It should be noted that no estimate of the minimum requirements in respect of cargo is given as no centrally held data concerning cargo capacity is held. For aircraft in commercial operations the minimum requirement is 17 SDR's per kilogram.

It should also be noted that as the estimates given are based on a number of variable items, if any of the items used in the calculation are incorrect then this will affect the amounts quoted.

In particular, as the estimate is based on a fluctuating exchange rate between SDR's and Pounds Sterling the operator or air carrier must ensure that they have adequate cover at all times.

For the purposes of this calculation if the Maximum take-off mass of the aircraft is less than 500kg it is assumed that the aircraft is used for non-commercial purposes or local flight instruction which does not entail crossing international borders. As such no estimate for the minimum required cover for risks of war or terrorism is given. If the aircraft has been declared as being used for commercial operations then an estimate of the minimum required cover risks of war or terrorism is displayed.

Minimum cover (combined single limit) for commercial operations

As there are different levels of cover required depending on whether the aircraft is used for commercial or non-commercial operations two separate estimates are included.

For details of how the calculation is made, please see the entry above.

Minimum cover (risks or war or terrorism)

For details of how the calculation is made please see the entry for Minimum Cover (Combined Single Limit) for Non-Commercial Operations.

Non-commercial operations

As different levels of cover are required for commercial on non-commercial operations this field identifies whether the registered owner has declared that the aircraft is used exclusively for non-commercial operations. If no such declaration is made the field will show "Not Declared".

State aircraft

State aircraft are exempt from the requirements of Regulation (EU) No 785/2004 as retained (and amended in UK domestic law) under the European Union (Withdrawal) Act 2018, if the registered owner has declared that the aircraft is used exclusively as a state aircraft the details will be shown here.

A state aircraft is one that is used exclusively in military, customs and police services.

Noise level, limit and margin

Noise levels are measured differently for different classes of aircraft and the results are displayed here. For aircraft certificated to Chapter 3 and Chapter 4 additional information on the noise limit for the particular aircraft is also given as is the difference between the actual noise level and the noise limit. The difference is displayed in the Margin field.

Cumulative margin

For Chapter 3 and Chapter 4 aircraft this figure is the sum of the three noise level measurements and the amount they are below the maximum permitted for the aircraft in question. For further information see the ICAO noise database.
