Endeavor CRJ900/700 SYSTEMS
(workbook) Powerplant, Fuel, Fire Questions
with Correct Answers
Describe the normal start sequence and indications Start switchlight illuminates
Pneumatic valves open
FADEC opens ATS valve (Engine Start Valve)
L (R) ENGINE START status message
20% N2: Thrust lever to Idle, FADEC: energizes L(R) Auto Ignition
50% N2: FADEC closes ATS valve
What would you do if the starter didn't cutout automatically at 50% N2? Press the Stop
Button and run the Emergency Checklist
You receive a HOT indication on your ITT gauge during start, what does this mean, and what
would you do? Hot Start, FADEC has detected that ITT has hit a specific limit and is
climbing too fast. As a pilot you can put the Thrust Lever to Shut Off and abort the start attempt
,How would the FADEC respond to a HOT START? If FADEC is working correctly, it
will automatically abort the start and shutdown the engine
How would the FADEC respond to a hung start? If FADEC is working correctly, it will
automatically abort the start and shutdown the engine.
What would the FADEC do if you tried to introduce fuel during start with the ITT > 120 C?
FADEC will abort start. Limition is for no trust lever movement from shutoff to idle when
ITT is above 120C on ground and 90C in air.
Describe the FADEC Auto-Relight function: FADEC detects the flameout, energizes
ignition. Pilots receive L/R Auto- Ignition Indication as FADEC is attempting to relight the
engine
What if the engine parameters fall outside the Auto-Relight envelope? FADEC will stop
attempting to relight and gives the pilot a R/L Engine Flameout Caution message.
Which thrust rating(s) would you receive if you advance the thrust levers to the MAX POWER
detent? APR on all working engines
, Which thrust rating(s) would you receive after pressing the HIGH PWR SCHEDULE switchlight
with the thrust levers in the CLB detent? MCT. HIGH PWR is PROHIBITED BY 9E
Which thrust rating(s) would you receive after losing an engine with the thrust levers in the
TOGA detent? APR
Which thrust rating(s) would you receive after losing an engine with the thrust levers in the CLB
detent? MCT
What thrust setting would the FADEC program if you were to lose an engine while operating in
the CRZ range? A proportional Increase
How do we control the thrust reversers? Arming Switches near the quadrant and Thrust
Lever quadrant controls
What creates motive flow? Extra fuel from the engine driven fuel pump
