In a fixed wing aircraft including at least one main fuel tank (14) in the wing and an associated surge tank (16), an aircraft fuel tank inerting system comprises a source (20) of inerting fluid, a flow passage (22) for supplying said inerting fluid to said tank and discharging it into said tank through at least one discharge outlet (24), and said flow passage (22) includes a pressure relief arrangement (26; 36) adapted to discharge into said surge tank (16) if the pressure in said main fuel tank (14) exceeds a predetermined threshold. |
