Monitoring the pressure of an aircraft tyre 3-8 by taking two or more tyre pressure readings from a respective pressure sensor 3a-8a and calculating a deflation rate based on the pressure readings. Each pressure reading may be normalised by the temperature of the tyre or the load applied to the landing gear 2. The pressure data may be transmitted to a cockpit computer (13, figure 3) via a wired or wireless connection. The time for the tyre to deflate to one or more reference pressure levels can be estimated from the calculated deflation rate. A warning may be provided if the estimated deflation rate exceeds a threshold value. A computer may be provided to calculate the deflation rate or estimated time(s) and these may be displayed, for example on a display (21, figure 4) in the cockpit of an aeroplane. The deflation rate may be estimated using least-squares fitting of a straight (or curved) line 30. The method and apparatus may be used for in-flight monitoring of the aircraft tyre pressure.
