I can't remember all the flight details but I think (!) with one engine inoperative you are restricted to a crew ferry flight only, No Pax. At one point you had to have had the training but things may have changed since I was last involved.
A "Failed Engine Ferry Kit" may be needed, probably at vast expense, to prevent engine rotation depending on the possible cause of the failure i.e. if the failure affected the mechanical condition. So the fan has to be locked and the HP stage by removing the Start/Gen.
It really isn't that simple if done by the book, but I have seen it done not by the book!
The AFM limitations were
VFR
Dry Runway
Antiskid must be operative
Icing Conditions not permitted
Flight over densely populated areas on T/O and Approach not permitted
Crosswind limitation depending on 1 or 3 engine inoperative
Training to be approved by the relevant Authority
I don't remember Dassault permission being required.
Depending on the failure location it was usually easier just to bring someone in!!!
