A method of monitoring engine performance parameters of a gas turbine engine during its operation. The method includes sensing the performance parameters and generating analog sensor outputs, producing digital data by conditioning the analog sensor outputs with at least one hub unit that is mounted sufficiently close to the engine to be subjected to a first temperature in excess of 125EC, receiving the digital data from the hub unit with a collector unit subjected to a second temperature of less than the first temperature, receiving the digital data from the collector unit with a distributor computer unit subjected to a third temperature of less than the second temperature, and processing the digital data with the distributor computer unit to assess the engine performance parameters of the engine. The conditioning step is performed with a control circuit board and at least one signal conditioning circuit board within the hub unit.
