GENERATOR SPEED GAUGE
Generator speed is indicated as a percentage of maximum safe operating speed (rpm), from 0 to 120%. If
generator speed exceeds 104% a warning condition occurs.
Figure 3-7 Generator Speed Gauge
ITT GAUGE
The Interturbine Temperature (ITT) Gauge ranges differ for engine off/start and running conditions. Values
between 200 and 1200 degrees Celsius (°C) are shown at engine start; values change to 200 to 900°C when
the engine starts running. When the engine is not running, ‘OFF’ is annunciated above the ITT readout; this
changes to ‘STRT’ upon engine start. No annunciation is shown when the engine is running normally.

Engine Start Normal Engine Off
Temperatures above which warnings occur are indicated by red tick marks along the ITT Gauge. Refer to
comments for the ‘ITT’ CAS message in Table 3-5 for warning issuance criteria.
OIL PRESSURE AND TEMPERATURE GAUGES
Engine oil pressure and temperature are shown along horizontal bar indicators below the engine gauges.
Oil pressure is shown in pounds per square inch (psi) and temperature in degrees Celsius (°C).
