Flight schools: approved training organisations (ATO) and declared training organisations (DTO)

All organisations that wish to obtain an approved (flight) training organisation (ATO) certificate or a declared (flight) training organisation (DTO) certificate must apply to the Directorate of Civil Aviation (Direction de l'Aviation Civile – DAC).

Who is concerned

All organisations that wish to:

  • obtain an ATO certificate; or
  • be declared a DTO.


To be eligible to obtain an ATO certificate in Luxembourg, or to file a declaration as a DTO, organisations must have their permanent establishment in Luxembourg.


For approval of an ATO or approval of an additional course, organisations applying for the certificate must pay a tax and a fee by wire transfer to the bank account of ALSA S.A., and the transfer must mention the appropriate reference information as listed in the table below.

Account holder: Luxembourg Aviation Safety Agency (ALSA S.A.)
Bank account: IBAN LU77 0019 3655 1997 3000 (Swift Code: BCEELULL)
Re: "Reference: xx" (mentioning the reference of the procedure as listed in the table below)

The amount of the fee for the approval and ongoing annual oversight of an ATO is determined based on time spent processing and analysing the applicant's case within the limits set forth in the table below.

For the approval of an additional course, a EUR 106 tax, plus a fee based on the amount of time spent, will be charged.

Before the application is filed, an advance payment is due. This payment corresponds to half of the minimum amount due. The payment is non-refundable and will be put towards the total fee.

Proof of payment must be enclosed with the application.
