Note 18: Gas producer speed as shown under “Engine Limits” are maximum permissible speeds. The gas producer
speed for rated power output varies with individual engines and must be determined during engine
calibration and stamped on the engine data plate.
Note 19: The rated gas producer speed shown on the temperature limit placard installe d on the instrument panel must
correspond to the engine data gas producer speed. Gas producer speed limits also vary with the schedule as
