The CAS is moved to a window on the right side of the display. CAS messages are treated in the same way as they are during normal display. Messages are prioritized by criticality.

EIS information is presented using horizontal and vertical bar indicators 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 or green and readout text is green. Refer to each instrument description for additional details on display behavior.
When an unsafe operating condition occurs, the pointer and readout color change to indicate a caution (yellow) or warning (red). If the time limit for an unsafe condition is exceeded, the color of the sliders, pointers, and digits may change to denote an increase in priority level, even if the parameter is still within in the lower priority condition range. If sensor data for a parameter becomes invalid or unavailable, a red “X” is displayed across the indicator and/or readout.

Engine Stagetagetage Rotationotationotationotation Speeds (N1 and N2)
The N1 display (Figure 3-6) indicates the engine fan rotation speeds while the N2 readouts (Figure 3-7) show the engine high pressure turbine rotation speeds. Both are shown as percentages. The N1 and N2 displays are shown in the same format in reversionary mode.
The N1 display ranges from 20 to 110% of maximum rotational speed. Values and limits are obtained from the Full Authority Digital Engine Controller (FADEC). When the N1 values of the engines are synchronized, ‘SYNC’ appears in green between the readouts below the scale. If N1 drops below 20%, the sliders are removed from the scale while the readouts remain displayed below.
An N1 target based on the indicated Thrust Mode is shown for each engine by a bug along the scale. The readout in the box at the top of the scale is the minimum N1 target value for both engines. When the Thrust Lever Angle (TLA) position corresponds to the indicated Thrust Mode (Table 3-1), the indication is shown in green; otherwise, the indication appears in white.

The N2 readouts are located beneath the ITT display. At engine start, the readouts appear in white. Once normal operating conditions are reached, the readouts change to green.

Oil Pressure and Temperatureemperature
The oil pressure and temperature for each engine are shown below the N1 display under normal display operating conditions. Oil pressure is shown in pounds per square inch (psi) and temperature in degrees Celsius (°C). When oil pressure and temperature are in the normal operating range, no readout is provided. When an abnormal operating condition occurs, the readouts appear in the corresponding color. In reversionary mode, only the readouts are shown.
Figure 3-8 Oil Display (Normal Mode)
Fuel Displayisplay
The fuel display is located beneath the oil indicators and shows the fuel quantity in pounds (lb) and fuel flow in pounds per hour (pph) for each engine, the total fuel quantity, and the fuel tank temperature in °C. Fuel information is provided primarily by the Fuel Quantity Signal Conditioner (FQSC), which has a fuel quantity processor for each tank. Fuel display can also be configured for display in metric units.
