Abstract
An apparatus is disclosed for monitoring the load on at least one part of an aircraft landing gear during landing of the aircraft. The apparatus comprises a housing containing a sensor which senses a parameter indicative of the load in the part of the landing gear, a processor which receives signals from the sensor and processes the signals to produce data representative of the parameter measured by the sensor, a battery which provides electrical power to the processor, a memory for storing measurement data from the processor, and a wireless transmitter which is controlled by the processor. The wireless transmitter is arranged to transmit at least some of the measurement data from the processor to a remote device located outside of the housing.

24. A method for monitoring the load on at least one part of an aircraft landing gear during landing of the aircraft, said method comprising the steps of:
-
monitoring output from a landing gear deployment sensor for a first indication indicating that the landing gear of an aircraft has been deployed; obtaining strain measurements from one or more parts of said landing gear in response to said first indication until one or more of said strain measurements exceeds a first predetermined strain threshold indicating a landing event having occurred; storing data representing the peak strain measurement if said peak strain measurement exceeds a second predetermined strain threshold indicating that said landing event represented a hard landing; and enabling wireless transmission means in response to said storing of said peak strain measurement data for transmitting said peak strain measurement data from said aircraft to an external device. - View Dependent Claims (25, 26, 27, 28, 29, 30, 31)

32. Apparatus for monitoring the load on at least one part of an aircraft landing gear during landing of the aircraft, said apparatus being operable to:
-
monitor output from a landing gear deployment sensor for a first indication indicating that the landing gear of an aircraft has been deployed; obtaining strain measurements from one or more parts of said landing gear in response to said first indication until one or more of said strain measurements exceeds a first predetermined strain threshold indicating a landing event having occurred; store data representing the peak strain measurement if said peak strain measurement exceeds a second predetermined strain threshold indicating that said landing event represented a hard landing; and enable wireless transmission means in response to said storing of said peak strain measurement data for transmitting said peak strain measurement data from said aircraft to an external device. - View Dependent Claims (33, 34, 35, 36, 37, 38, 39)
