INDEX

EIS information is presented using gauges, horizontal and vertical bar indicators, slide bars, and digital readouts.

Green ranges on the instrument scales indicate normal ranges of operation; yellow and red bands indicate caution
and warning, respectively. During normal operating conditions, an instrument’s title appears in white and the
readout text is green. When an unsafe operating condition occurs, the title and readout color change to yellow
or flash red, indicating a caution or warning. If the sensor data for a parameter becomes invalid or unavailable, a
red “X” is displayed across the indicator and/or readout.

ENGINE PARAMETERS

The PA-46 Meridian’s EIS displays torque, interturbine temperature, propeller speed, and generator speed,

using arc gauges.

TORQUE GAUGE

The Torque Gauge displays values in foot pounds. If torque exceeds the maximum safe operating range a

warning condition occurs.

ITT GAUGE

NOTE:

Refer to the Pilot’s Operating Handbook (POH) for engine operating limitations.

The Interstage Turbine 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 is running. When in start mode the yellow band extends from 770 to 1000° C.
When the engine is running the yellow band extends from 770 to 800° C and the red band is at 800° C.
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.
