Abstract: A system for purging an aircraft fuel reservoir includes a body (48) configured to be assembled on the aircraft fuel reservoir (16) and a valve (50), received in the body (48), and having a released configuration of an outlet channel (70) and a tight closed configuration of the outlet channel (70). The system further comprises a transport pipe (44) secured to the body (48), the transport pipe (44) being configured to be fluidly connected to a fuel supply pipe (20) configured to supply an energy producing device. The transport pipe (44) extends at least between a fuel suction inlet (52) and a discharge outlet (54), the suction inlet (52) being configured to emerge in the aircraft fuel reservoir (16) and the discharge outlet (54) being configured to emerge in the supply pipe (20) when the body (48) is mounted on the aircraft fuel reservoir (16).

Abstract: Aircraft fuel tank, which has a visual control system inside the tank, includes at least a side wall (12), an upper wall (14) and a lower wall (16), the tank (10) comprising a visual inspection system (22) inside the tank (10). The visual inspection system (22) includes an inspection eyepiece (24) arranged in one of the walls (12, 14, 16), a light inlet (26) arranged in one of the walls (12, 14, 16) and configured to allow light from an artificial light source (30) situated outside the tank (10) to enter the tank (10), and a light guide (28) protruding inside the tank (10) from the light inlet (26) to guide the light produced by the artificial light source (30) to the inside of the tank (10).
