MAXIMUM CRUISE TORQUE BUG
For normal cruise flight when prop RPM is between 1600-1900, a
maximum cruise torque "bug" is included on the arc. This indicates
maximum allowed cruise torque per the cruise performance and
maximum torque charts in Section 5, Performance. The blue maximum
cruise torque bug located on the EIS torque indication is not to be used
as the primary means of setting cruise torque. Always refer to the
appropriate performance chart in Section 5 of the POH/AFM.

PROPELLER RPM INDICATIONS

The PROP RPM is indicated numerically below Gas Generator Ng %
RPM indicator. The digits are white with RPM between 0-1599 RPM,
green between 1600-1900 RPM, and white numerals on a red
background when RPM is greater than or equal to 1910 after a 20
second delay. The instrument is electrically operated from the propeller
tachometer-generator which is mounted on the right side of the front
case.

ITT INDICATION

Interstage Turbine Temperature (ITT) is indicated below torque gage
and is round dial gage with a white pointer. This instrument displays
gas temperature between the compressor and power turbines. With the
engine off, or during start, ITT indicator displays a green band from
100°C to 870°C and a redline at 871°C. The gage is graduated at 100
degree intervals from 600°C to 1100°C.
With the engine running, a green arc indicates normal operating range
from 100°C to 825°C, an amber caution arc from 826°C-849°C and a
redline at 850°C. The gage is graduated at 50 degree intervals from
600°C-950°C.
During any temperature exceedance, the digital readout will reverse to
white digits on a red background and the moving pointer will turn red.
