Abstract:
1. An aircraft tank system comprising: a plurality of tank cells for receiving fuel, a fuel line connecting the plurality of tank cells to a fuel inlet connection, a shut-off valve, an aeration/deaeration line connecting the plurality of tank cells to the shut-off valve, which leads to an environment outside the tank cells, wherein the shut-off valve is adapted in an open position to connect the plurality of tank cells to the environment and adapted in a closed position to isolate the plurality of tank cells from the environment, and a control device that is adapted during filling of the tank cells with fuel to maintain the shut-off valve in the closed position, wherein there is connected to the aeration/deaeration line an exhaust air outlet connection, which during filling of the plurality of tank cells with fuel is connectable to an aeration/deaeration connection of a storage tank of a refueling unit in order during filling of the plurality of tank cells to convey exhaust air from the tank cells into the storage tank of the refueling unit, wherein the shut-off valve is maintained in the closed position as long as the exhaust air outlet connection is connected to the aeration/deaeration connection.
