@MoateAir: I am afraid the "Fly in France" website should not really be recommended. With all respect this one-person initiative merits, it seems to be out of date. It even still mentions and discusses paper charts from Jeppesen. And it does not mention the all-important info about military low-level flying, or I should have missed it.
Besides, the amount of spelling errors gave me the creeps but it seems I am more sensitive in this area than most people and particularly most English people.
