Abstract
The system is provided for controllably monitoring data associated with operational characteristics of an engine. The system determines a maintenance activity requirement based on such characteristics. The system includes a plurality of transducers associated with the engine and connected to a programmable logic device. Signals from the transducers are continuously monitored and stored in an associated storage device. In response to predetermined sets of operational characteristics, an indication of when maintenance is due on the engine is produced by the logic device.
