A tyre pressure sensor device (122) for a wheel (112) of an aircraft (102) is disclosed. The device (122) includes a pressure sensor (124) for measuring the internal pressure of a tyre, a temperature sensor (126) for measuring a temperature local to the tyre (116), a memory unit (131) local to the tyre for storing data, and a control unit (128) local to the tyre arranged to record in the memory unit (131) data in respect of multiple readings over time. The data recorded for each reading includes an indication of the time of the reading, the pressure as measured by the pressure sensor and the temperature as measured by the temperature sensor. Multiple successive measurements may be taken and recorded over time, both when the aircraft is on the ground and when the aircraft is in flight. Data may be uploaded to a portable handheld device (140), for example, for analysis when maintaining the tyres in their correctly inflated state. |
