Press the STOP button, monitor deceleration to 0 % RPM. At 0 % RPM, select the APU master knob to the OFF position.
[Powerplant] Explain the start sequence of the engine.
After selecting START, verify N2 rotation within 10 seconds and oil pressure rise. At approximately 14% N2, verify ignition on. At approximately 28.5% N2 or 12 seconds after ignition is activated, verify fuel flow and then monitor ITT for light-off (within 10 seconds of fuel flow) and verify N1 rotation. Fuel flow and ITT indications should increase at approximately 31.5% N2. Monitor ITT, N2 and oil pressure throughout the start so as not to exceed normal parameters.
[Powerplant] When positioning the START/STOP selector knob from STOP to START, how long should the knob be paused in the run position prior to start and why should this pause occur?
When positioning the START/STOP selector knob from STOP to START, pause for 2 seconds in the RUN position prior to selecting START. Quickly moving from STOP to START without pausing in the RUN position may be misinterpreted by the FADEC as a shutdown command, thereby triggering an un-commanded, on-ground engine shutdown.
[Powerplant] How is light-off recognized during engine starts?
Light-off occurs when the digital numbers on the ITT indicator increases.
[Powerplant] When should the ignition be placed to on?
If standing water, ice, slush or snow is present on the runway for takeoff During heavy precipitation Takeoff into suspected wind shear Severe (Should be “moderate or greater”) Turbulence When the temperature is below 10 degrees C (Should be 5 degrees C) and the engines have been shut down for more than 90 minutes As directed per the QRH

[Powerplant] What happens when a thrust reverser deploys in flight?
The FADEC reduces the engine thrust to idle, however the thrust lever will not actually move.
[Powerplant] What happens to the engine when the FADEC in control fails?
The other FADEC takes over control of the engine.
[Powerplant] What happens when both FADECs for an engine fail?
An engine shutdown would occur. The engine requires at least one FADEC to operate.
