Pilot Language Proficiency

Information on language proficiency requirements for pilots

Aeroplane, helicopter, powered-lift and airship pilots required to use the radio telephone must have a language proficiency endorsement on their licence in either English or the language used for radio communications involved in the flight.

The endorsement shall indicate the language, the proficiency level and the validity date.

Further details of specific requirements can be found in CAP804, section 4, Part M, FCL.055


The applicant for a language proficiency endorsement shall demonstrate, at least an operational level of language proficiency both in the use of phraseologies and plain language.

Further details of specific requirements can be found in CAP804, section 4 – Acceptable Means of Compliance and Guidance Material

If you are the holder of an existing UK issued Flight Crew Licence which has not already been converted to a Part-FCL licence, then this licensing action is likely to result in the compulsory conversion of your existing licence to a Part-FCL licence, for which an additional application form / information will have to be submitted, and additional requirements may have to be met. 

As such, please refer to the conversion information available on our website in addition to the information on this page.


The fee that you need to pay will depend on your circumstances; for example:

  • whether you already hold a UK licence, and whether that licence has already been converted to an EASA-FCL licence,
  • whether your application will be made at the same time as applying for something else. 

To assist in the interpretation of the scheme of charges a Fee Calculator has been developed, which derives the fee for this application type for your particular circumstances.  

Processing time

We endeavour to process applications in 10 working days from receipt.

Validity period

EASA-FCL licences have no expiry date and are therefore valid for the holder’s lifetime.

You will need to provide

Application form SRG1199 and supporting material as applicable for your circumstances and the type of application; as per the guidance attached to each application form.

Associated rules and regulation

How to apply

Once all of the requirements above have been met, the application should be submitted by post or in person to:

Licensing Department,
Licensing and Training Standards,
Aviation House,

What to expect

A desk based assessment from a Flight Crew Licensing Officer or Assistant.  

Following an acceptable assessment your licensing application will be processed signed and despatched.

  • We will contact you if we have any queries regarding your application and may keep your application pending whilst any additional requirements are met.
  • An assessment and refund fee may be charged if the assessment results in the rejection of your application.  This will also be applied if you choose cancel your application.

In some circumstances an applicant for a conversion of an existing licence to an EASA licence may also require a national licence to fly Annexe II aircraft (Aircraft not on the EASA Type List).  This process is undertaken by the Licensing Officer who assesses your application.
