"No aircraft shall fly above a town or any inhabited district except at such an altitide that, in the event of the failure of its means of propulsion, it can land outside the town or inhabited district, or upon an aerodrome open to public use." In order that this regulation may be clearly interpreted, the following amplifying rules have now been applied by the French Government:— (i) No inhabited district, no matter what its size, may be flown over at an altitude of less than 500 metres (1,640 feet) (ii) Towns of 10,000 to 100,000 inhabitants may not be flown over at an altitude of less than 500 metres (1,640 feet) in the case of multi-engined machines, and less than 1,000 metres (3,281 feet) in the case of single-engined machines. (iii) Towns of more than 100,000 inhabitants may not be flown over at an altitude of less than 1,000 metres (3,281 feet) in the case of multi-engined machines, and less than 2,000 metres (6,562 feet) in the case of single-engined machines. 2.
