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.

THRUST MANAGEMENT
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 antiice
demands are met.
· Prevent ice accumulation on the fan, on the ground or inflight.
· Ensure that the variable frequency generators stay on line.
Low idle range is commanded when in the forward idle position and the airplane is not in an
approach configuration.
High idle is commanded when in the forward idle position and the airplane is in an approach
configuration.
If the EEC cannot determine whether or not an approach configuration has been set up, then the
EEC will default to high idle.
Forward thrust is set by positioning the thrust levers (manually or automatically). Between idle and
maximum thrust are various thrust levels such as:
· Maximum Takeoff
(MTO)
· Maximum Climb (CLB)
· Flexible Climb (Flex CL)
· Maximum Continuous (MCT)
· Flexible Takeoff
(Flex TO)
Reverse thrust is a manual selection only.
Each thrust lever drives a dual channel RVDT. Each channel in the RVDT is dedicated to an EEC
channel.
