Max 0 to 55 m depending on take-off altitude, forbidden in places
Floor published as an altitude (AMSL), not a height above ground: the flyable height depends on the terrain elevation.
You may fly below 832 m altitude (AMSL). The corresponding height above ground depends on the terrain elevation at your position.
How to read this value
AMSL = altitude above mean sea level. "m above ground" (AGL) = height measured from the terrain.
Zone floor: aerodrome reference altitude (802 m AMSL) + regulatory height (30 m, French decree of 3 Dec 2020) = 832 m AMSL.
Across the zone (ground between 777 and 1103 m altitude), the available height goes from 0 to 55 m depending on where you are. In places the floor reaches the ground: no flight there without an agreement.
