Oil Temperature Indication

 


OIL TEMP Readout
Displays the current oil temperature.
High Temperature Redline
If the oil temperature exceeds 160°C the
OIL TEMP will turn red and will flash (engine
operating).

Low Temperature Redline
If the oil temperature is lower than . 30°C
the OIL TEMP will turn red and will flash.

LOW Temperature Amberline
If the oil temperature is 20°C or less but higher than . 30°C the OIL TEMP will turn amber.

Oil Pressure
The oil pressure transducer provides an indication of the pressure between the oil feed and scavenge lines.

ENGINE VIBRATION MONITORING SYSTEM (EVMS)
The EVMS provides the crew with a means of continuously monitoring any imbalance of the rotating assemblies, N1 and N2. the EVMS is a stand alone system, independent of FADEC.
The system comprises one airframe mounted Engine Vibration Monitoring Unit (EVMU) that processes signals from dedicated N1 and N2 speed probes and vibration transducers. The EVMU provides indication of engine vibration on EICAS.

NOTE
N1 VIB is not displayed unless:

 Core VIB is displayed or,

 L or R N1 VIB is >1.0 in/sec.

N2 VIB Indication
If the N2 vibration monitor readings are greater than 1.2 in/sec then theVIB icon is displayed.

N1 VIB Indication
If the N1 vibration monitor readings are less
1.0 in/sec, then the N1 is displayed green. If N1 is greater than 1.0 in/sec then the readout is displayed amber.

POWER PLANT
 
The EEC uses one of two modes to set steady state power above idle, EPR or N1 mode. Although idle is controlled to a RPM value, an equivalent EPR is also calculated so that the EEC can establish a Throttle RVDT Angle (TRA) to EPR relationship throughout the operating range.
The EEC will control idle to prevent the engine from operating below minimum limits to:
.  
Ensure that cabin bleed and anti-ice demands are met.

.  
Prevent ice accumulation on the fan, on the ground or inflight.

.  
Ensure that the variable frequency generators stay on line.

.  
Ensure cowl anti-ice demands are met on the ground or inflight

.  
Protect against inclement weather by opening bleed valves to aid rejection of water and maintain the surge margin, commanding continuous ignition to maintain combustion, as well as increasing engine speed by an appropriate margin.
