An aircraft comprising a plurality of fuel storage chambers located within said aircraft, at least one of said fuel storage chambers being located within a wing of said aircraft, said wing having an outward portion associated with the wingtip and an inward portion, each of at least two of the fuel storage chambers being provided with a venting conduit for permitting fluid communication with a venting chamber of a venting chamber system, wherein the venting chamber is located inwardly of said at least one fuel storage chamber and has a venting outlet for permitting fluid communication between the venting chamber and the exterior of the aircraft,
- the aircraft comprising a venting chamber conduit provided between the venting outlet of the venting chamber and an overflow chamber, the overflow chamber being provided with an overflow venting outlet for permitting fluid communication between the overflow chamber and the exterior of the aircraft, the overflow chamber being located in the outward portion of the wing.
A fixed-wing aircraft with two anhedral wings, said aircraft comprising a plurality of fuel tanks located within said aircraft, each of said wings having an outward portion associated with the wingtip and an inward portion, each of at least two of the fuel tanks being located within mutually different wings of the aircraft and being provided with a venting conduit for permitting fluid communication with a venting chamber of a venting chamber system,
- wherein the venting chamber is disposed within a fuel tank located centrally relative to the wings of the aircraft and is located inwardly of said at least two fuel storage tanks and has a venting outlet for permitting fluid communication between the venting chamber and the exterior of the aircraft, wherein the aircraft further comprises two surge tanks, the surge tanks being located in the outward portion of mutually different wings of the aircraft, a venting chamber conduit being provided between the venting outlet of the venting chamber and each surge tank, each surge tank being provided with an overflow venting outlet for permitting fluid communication between the surge tank and the exterior of the aircraft.
