According to new regulations in The Netherlands, from August 2021, the mandatory GENDEC for General Aviation flights must now be submitted digitally and at least two hours prior to departure to the Dutch Authorities (Royal Netherlands Marechaussee).

Gendec.EU (originally Gendec.NL) has been created by CloudAviation to minimize the additional administrative burden for General Aviation pilots. This website allows you to create and submit GenDecs or GARs in a user friendly and electronic way, without compromising your privacy, and without the need of figuring out the routing of your GenDec or GAR. We offer you a personalized environment to store your own aircraft, passenger and crew details for re-use, and manage submitting the GenDec or GAR, once completed.

This website can be used (at the moment) to create, as required:

  • General Declarations (GenDecs) for General Aviation flights from a non-Schengen country to The Netherlands, or flights departing from The Netherlands to a non-Schengen country. See link for more information on Schengen countries (opens new window).
  • General Aviation Reports (GARs) for General Aviation flights to or from the United Kingdom (required for UK border crossing flights)
(Note: This site is not limited to only flights between NL and the UK.)
In both cases, these documents/information will be distributed electronically to the relevant Competent Authorities (like Border Police or Customs). In case of a flight between two countries that both require this information, both Authorities will be informed simultaneously.

Due to an arrangement with Dutch Border Police (KMAR), we were able to agree to a procedure of 'linking' your submitted General Declaration to your mandatory Flight Plan. This means there is no need to change or cancel the submitted GenDec once your flightplan changes or is cancelled. Simply delaying or cancelling your Flight Plan will keep border police informed.

For a delay or cancellation of your flight to the UK however, cancelling your submitted GAR (and submitting a new one in case of a delay) is still mandatory!

For your personal records, you can download a copy of the submitted GenDec and GAR, and we strongly advise you to bring a paper copy along on your flight. You can be asked to show the document.

In the future, gendec.eu will extend to other countries with similar requirements.


According to the European law , more specific the Schengen Borders Code (EU 2016/399), a General Declaration is a mandatory immigration document for flights leaving or entering the European Union and/or the countries of the Schengen Treaty. The information provided with a General Declaration allows for effective immigration and border control. The Dutch Border Police (Royal Netherlands Marechaussee) requires a notice in advance for such flights for General Aviation traffic (both inbound and outbound). This notice must be provided at least 2 hours prior to take-off by means of a submitted General Declaration (hereinafter referred to as GenDec).

The Schengen Treaty allows free travel of persons between the countries that signed the Treaty (which is a subset of countries of the European Union). However, there are some exceptions:

  • United Kingdom and Ireland are part of the EU, but not part of the Schengen zone, therefore a GenDec is required for the Netherlands (both inbound and outbound), as well as a General Aviation Report (GAR) for the UK, when entering.
  • Norway and Switzerland are not part of the EU, but are participating in the Schengen zone, so no GenDec is required.
