GENERAL
The airplane is powered by two fuselage-mounted Rolls-Royce
turbofan engines. Engine denominations, thrust (installed, static sea
level) and flat rates are as follows:

NOTE: - Max T/O thrust and flat rate values for AE3007A1P and
AE3007A1/3 are based on T/O RSV thrust.
- Max T/O thrust and flat rate values for AE3007A1E are
based on E T/O RSV thrust.
The AE3007 is a high bypass ratio, two-spool axial flow turbofan
engine. The main design features include:
−
A single stage fan,
−
A 14-stage axial-flow compressor with inlet guide vanes and five
variable-geometry stator stages,
−
A 2-stage high pressure turbine to drive the compressor,
−
A 3-stage low pressure turbine to drive the fan,
−
Dual, redundant, Full Authority Digital Electronic Controls
(FADEC),
−
Accessory gearbox,
−
Air system for aircraft pressurization and engine starting.
Each engine is controlled by redundant FADECs. The FADECs also
provide information to the EICAS, although some parameters signals
are provided directly from engine sensors. All powerplant parameters
are indicated on the EICAS, which also provides warning, caution and
advisory messages.
The cockpit control stand incorporates two thrust levers, one for each
engine, and four buttons for engine thrust rating selection.
Controls for ignition, FADEC, takeoff data setting, takeoff rating
selection and engine Start/Stop are located on the overhead panel.
