ENGINE & AIRFRAME SYSTEMS
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).
Figure 3-11 Oil Pressure and Temperature Gauges
CABIN PRESSURIZATION
Cabin pressurization information (cabin altitude, rate of change, and differential cabin pressure) is shown at
the top of the right EICAS column. Only readouts for cabin altitude and pressure differential are displayed in
Reversionary Mode.
Cabin altitude (ALT FT) is shown on a color-coded scale labeled in 5,000-ft increments with a readout (in
feet) below. Cabin altitude change rate (RATE FPM) is displayed on a scale in terms of 2,000 fpm increments
with a readout (in fpm) below. Cabin pressure differential (DIFF PSI), in pounds per square inch (psi), is
indicated on a color-coded scale with a readout. Selected Cabin Altitude is displayed in the TBM 850 as a digital
readout (in 100 ft increments) with a range from -1,000 to 11,000 feet.
