The complete group of theoretical subjects passed under an EASA Aeronautical Authority may be accepted provided that these materials are in force and duly certified.

Currently, the following options are considered provided that the requirements established for each case are met and accredited: 

• Through a Training Course in an Authorised Training Organisation (ATO or DTO)
• Through the acceptance of ratings of type or class entered in license of a third country ICAO 
• Through the recognition of national military licences

The following options are currently envisaged provided that the requirements are met and accredited in each case, as applicable: 

• Through a Training Course in an Authorised Training Organisation (ATO or DTO)
• Through the conversion of license of a third country ICAO 
• Through the recognition of national military licences

An authorisation is an official authorisation that must be entered into force in the PART FCL license for the exercise of its powers. A rating may grant you additional privileges or allow you to do something you can't do without it, such as flying at night or flying on a different class of aircraft. 

The PART FCL licenses consist of at least: 

• Aeronautical medical certificate in force. 
• Type or class rating in force 
• Attributions of radiotelephony and language competence in force

Currently, both for obtaining a PART FCL flight licence and a rating are the following training organisations that must be authorised in force by the Aeronautical Authority of an EASA Member State

• ATO approved training organisation
• Training organisation declared DTO 

The difference between the two is established at the training level in relation to the typology of courses that can be taught

Currently, the modalities of: 

• Modular training course where you will previously be the holder of a PPL license 
• integrated course or ab initio.

Licenses can be classified according to whether they comply with international standards of ICAO, the International Civil Aviation Organisation, or if they do not comply with them. The licenses they comply with are known as ICAO licenses and those that do not are known as non-ICAO licenses. Licences that do not belong to ICAO are not fully recognised internationally and are therefore only valid for use within certain states or Europe; for example, the LAPL license is only valid in EASA Member States.

Some aircraft are still regulated by individual national authorities issuing national licences such as ultralight aviation licences.

They are those licences that are issued in accordance with European standards and are equally valid and recognised throughout Europe. These are known as EASA (European Aviation Safety Agency) licenses and include the following: LAPL; PPL SFCL,BFCL,CPL, MPL, ATPL
