ENGINE INDICATION SYSTEM
INTERSTAGE TURbINE TEMPERATURE
The Interstage Turbine Temperature (ITT) Gauge is displayed at the top of the EIS. This gauge differs for
engine start and running conditions. Values between 200 and 1200 degrees Celsius (°C) are shown at engine
start; values change to 200 to 800° C once the engine has stabilized. A red triangle is displayed at 1090° C
during engine start as an aide to not exceed maximum starting temperatures. This is available in both normal
and reversionary modes.

TORqUE
The Torque Gauge displays engine workload in foot-pounds and is located beneath the ITT gauge. The values
range from 0 FT-LB to 1600 FT-LB If the torque remains above 1315 FT-LB for more than 2 seconds or exceeds
the value indicated by the red tick mark, a warning condition occurs.
