A non-rigid airship or hybrid air vehicle has a pressure-stabilised envelope (100) that includes at least one ballonet (102, 103). A system is provided for measuring the geometry of the lifting gas enclosure (101) within the pressure-stabilised envelope (100). The system comprises a plurality of sensors (104, 109) located outside the ballonet(s) but inside the envelope, for measuring the geometry of the enclosure. Some of the sensors (104) are arranged to measure an internal surface of the pressure-stabilised envelope (100), and others of the sensors (109) are arranged to measure an external surface of the at least one ballonet (102, 103).
