Abstract

A plurality of wireless engine sensors each sense an engine parameter as engine data and transmits wirelessly the engine data regarding the sensed engine parameters and receives data regarding a sampling rate. An engine monitoring module is mounted at the aircraft engine and a wireless sensor transceiver is configured to receive the engine data regarding sensed engine parameters from the wireless engine sensors. A first wireless transmitter is carried by the housing. A memory is carried by the housing. A processor is coupled to the memory, sensor transceiver and the first wireless transmitter and collects and stores in the memory engine data relating to engine parameters and transmits the engine data via the first wireless transmitter.
