Abstract

A monitoring system for an aircraft engine includes a plurality of wireless engine sensors that sense engine parameters based on an engine sampling algorithm. The wireless engine sensors receive a new engine sampling algorithm to change the engine parameter sensing and generate engine data based on the new engine sampling algorithm. An engine monitoring module is mounted at the aircraft engine and collects and stores in a memory the engine data and transmits the engine data over a wireless communications signal into the aircraft and receives a new engine sampling algorithm and transmits it to the wireless engine sensors. A wireless LAN is within the aircraft and receives the new engine sampling algorithm from a ground based control center and transmits the new engine sampling algorithm to the engine monitoring module.
