fly in france with nppl? yes you can ....
all microlights normally used in a member state of the european community, or party to the airspace agreement of the eec, and identified or registered in that state, are authorised for private flight over french territory, provided that:
(a) the microlight holds a flight authorisation(permit to fly) granted by that state or its delegated authority, on the basis of its compliance with a technical standard for safety.
(b)the pilot holds a valid licence IN THE MICROLIGHTS HOME STATE!!. the microlight must be operated in accordance with the rules and limitations applied by the state of origin, and within the limits of applicable french rules.
But what about us that have an NPPL but do not fly microlights?
