What is Lower Traffic Area (LTA) airspace in France?
@mins Has answered the question in his comment above:


  LTA: FL 115 to 195, UTA: FL195 to 660" (Wikipedia). Created in 1992, a LTA is a class-D CTA (E over Alpes and Pyrénées to allow VFR gliders) between and excluding other CTA (airways and TMA), and up to 12 NM of the shoreline. I've highlighted a class-E LTA nearby Perpignan TMA and the Spanish border on this SIA map. Synoptics of the French airspace (source).
