2. Monitors necessary operational parameters, including:

   a. Reduction gear oil supply pressure and bearing temperatures;

   b. Power turbine and gas generator speeds and vibration levels;

   c. Compressor inlet and discharge temperatures and pressures;

   d. Power turbine inlet temperature and pressure;

   e. Gas turbine bearing lube oil temperatures; and

   f. Exhaust gas temperature and pressure;

3. Performs performance calculations and compares results with ideal mapping data; and

4. Determines necessary changes to operational procedures or status.
