PRIMARY DISPLAY SYSTEM -EICAS DISPLAY FORMAT
Gear Position Indication
A single landing gear indication shows the condition of the nose, left, and right main gear during normal operation. A white UP shows when all gear are up and locked. A green DOWN shows when all gear are down and locked. When the gear are in transit, a series of white diagonal lines show. The gear display goes blank after the gear UP shows for ten seconds.
During non-normal conditions, a multiple gear indication shows all individual gear positions.
Flap Position Indication
During normal flap operation, a single thermometer style indicator shows for all flap segments. The indicator shows the flap lever detents of 0, 1, 5, 10, 20, 25, and 30 degrees along the scale. Zero is at the top. A horizontal bar and a digital readout show the commanded flap position. The digital readout shows when the flap handle is in detent. The bar and readout are green when the flaps/slats are in the commanded position. Otherwise they are magenta.
The flap position indication goes blank ten seconds after the commanded flap position is 0 and both the flap handle and the flaps are in the 0 detent.
During non-normal conditions, a multiple flap indication shows. The multiple indication shows all individual flap/slat segments for each wing.
Fuel Data
Total fuel quantity and fuel temperature show as white numerical readouts in the lower right corner of the display. TOTAL FUEL and TEMP show in cyan.
During a fuel imbalance condition, a fuel quantity block shows to help the crew balance the fuel in the main tanks.
A low fuel temperature condition causes the fuel temperature readout to change to amber.
During fuel jettison, the fuel temperature readout changes to fuel-to-remain indication.

PRIMARY DISPLAY SYSTEM -SECONDARY ENGINE DISPLAY FORMAT
General
The secondary engine display format shows on the center lower display unit (DU) at power-up. The format shows secondary engine parameters not required for continuous display. The ENG switch on the EICAS display select panel controls the display.
The display shows this information:
*
High pressure rotor speed (N2)
*
Fuel flow
*
Oil pressure
*
Oil temperature
*
Oil quantity
*
Engine vibration
*
In-flight start data.
N2
N2 shows as a digital readout and a round analog scale. The display units are percent RPM. Red lines and color code for exceedance are the same as the N1 display on the EICAS display format.
Fuel Flow
A digital readout shows fuel flow in units of thousands of kilograms per hour for each engine just below the N2 scale. There are no exceedance indications for fuel flow.

Oil Pressure, Temperature, Quantity
Oil pressure shows as a digital readout and filled, moving pointers on a vertical analog scale. Oil pressure has a lower red line limit and an upper and lower amber band limit.
Oil temperature shows as a digital readout in degrees C and filled, moving pointers on a vertical analog scale. Oil temperature has an upper and lower red line limit and a high and low amber band limit.
For both oil pressure and oil temperature, these change colors (white to amber to red) as the parameter exceeds applicable high or low limits:
*
Digital readouts
*
Readout boxes
*
Pointers.
Oil quantity shows as a digital readout in liters. For a low oil quantity condition, the digital readout changes to reverse video and a LO message shows next to the readout.
