Mark.... the costs are relatively trivial. The ULM manual required for the ULM theory test is 39 Euros and to register/sit the exam was either free or no more than 50'ish Euros. No on-site flying course is required.
I can see no reason why the english ops manual can't be translated and submitted to the DGAC. I have attached the MANUEL D’UTILISATION ET D’ENTRETIEN and the DOSSIER TECHNIQUE that we submitted to the DGAC for my old F550... these were completed to their format and provided the info they requested..... they give a flavour what was required then and still might be the case.
I stress that I went through all this a couple of years back.... I assume, like in most geographies, much has changed for commercial UAV flying in France. Without a ton of research that I don't have time for at the moment I suspect that I am out of date and it may be that the DGAC have streamlined/simplified the process given the demand for UAV flying in the intervening years. However, I hope I have been able to provide a flavour of what is required here in France.
I also attach a doc that I have just downloaded from the DGAC website (
Quelle place pour les drones dans le ciel français ? - Ministère de l'Environnement, de l'Energie et de la Mer) that outlines most of the requirements... this was released in August (2016).
I do not confess to being a current expert or up-to-date so some of what I have detailed here may now be out-of-date/ incorrect. Please do not take everything I have written as the gospel truth! ..... but if you want to make the jump and get certificated in France I would be happy to offer some further help.
