ENGINE & AIRFRAME SYSTEMS
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 pointer appears in white and the
readout text is green. When data is out of the range of the indicator or gauge, the pointer moves to the end of the
scale; readouts display as “___”.
When an unsafe operating condition occurs, the pointer and readout color change to yellow or flash red,
indicating a caution or warning. If a cautionary time limit is exceeded, the sliders, pointers, and digits may flash
red, even if the parameter is still within in the cautionary range (refer to each display description for details). 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 TBM 850’s EIS displays torque, propeller speed, generator speed, and interturbine temperature using arc
gauges.
TORQUE GAUGE
The Torque Gauge displays values from 0 to 130% of maximum safe torque. If the torque remains above
121.4% for more than 5 seconds or exceeds the value indicated by the red tick mark, a warning condition
occurs. The maximum climb torque is displayed as a white triangle (bug) while the optimum cruise range is
displayed as a white band on the Torque Gauge.

PROPELLER RPM GAUGE
Propeller speed is shown in revolutions per minute (rpm) from zero to 2200. If propeller speed slows
to where the gauge pointer enters the yellow range, a caution is issued. A propeller overspeed warning is
indicated if propeller speed exceeds the maximum safe operating speed.
