Engine

  1. What happens when the ignition switch is selected to override?
    Activates both igniters on the ground or in flight
  2. Can the igniters Be turned off during flight?
    The switch may be turned to the off position, but the FADEC disregards the command.
  3. What controls the engine?
    The FADEC
  4. What controls engine starting and provides hung start, hot start and no light off protection?
    The FADEC
  5. Does the FADEC provide engine start protection?
    Only on the ground, HOT, HUNG, NO LIGHT OFF
  6. Is there protection for HOT or HUNG starts during an in flight start?
    No
  7. How are engine thrust ratings controlled?
    By the FADEC
  8. What does the cyan line on the N1 gauge represent during the approach? When does it appear?
    • Min N1 req for icing conditions
    • Configured when anti ice is ON
  9. How is the N1 limit indicated on the EICAS?
    Red tick mark on N1 gauge.
  10. What sources are available for engine starting?
    • APU
    • Ground source
    • Opposite engine
    • Windmill start
  11. Where is external air for an air start connected? Will crew have an indication that the external air is connected?
    • Lower section of the wing fairing area.
    • Duct pressure on mfd synoptic page.
  12. What happens after 3 over speed detection events within 30 sec?
    FADEC will not relight the engine
  13. What does WML mean on the engine indication?
    • Windmilling engine
    • The FADEC has detected a flame out and the auto relight system is actuating to restart the engine.
  14. Where can the crew check the engine oil qty?
    On the MFD synoptic page
  15. What is ATTCS.? What controls it?
    • Automatic takeoff and thrust control system
    • Provides max thrust reserve according to current rate previously selected via the mcdu on the TO DATASET page
    • Controlled by the FADEC
    • Engagement only happens when the thrust levers reach the TOGA set position.
  16. What will trigger an ATTCS event?
    • N1 difference greater than 15% between the engines
    • Engine failure during TO or Go around
    • Wind shear detection
  17. How can the pilot command RSV power?
    By moving the thrust levers to the max position whenever the ATTCS is armed.
  18. When is thrust reverse available?
    Wow
  19. Thrust reverser must be stowed below what altitude?
    60 KIAS
  20. When is the thrust reverser displayed and what do the colors mean?
    • Whenever thrust reverser is not stowed
    • Green is fully deployed
    • Amber is in transition
    • Red means that there is a discrepancy between indicated and actual positions
  21. What position must the thrust lever be in to enable the thrust reverser trigger?
    Idle
  22. If the thrust reverser is placed in the MAX rev position and then released, what happens?
    It is spring loaded back to the Min rev position
  23. What happens when a thrust reverser inadvertently deploys?
    The FADEC limits the respective engine to idle.
  24. Can you deploy the thrust reverser on an engine that has failed on the landing roll?
    Yes, up to 30 sec. then it is locked out
  25. What is FLEX to?
    Reduced thrust takeoff based on assumed temp
  26. What is the max flex allowed?
    25%
  27. If you input a flex of 34,then change it to 39 how will it affect N1 target?
    It will drop your N1 target
  28. Use of reduced to procedures is not allowed on?
    • Runways contaminated with standing water, slush, snow or Ice.
    • Wet runways unless wet numbers to account for increased stopping distance are obtained
  29. Can you FLEX with WSHR advisory in affect?
    No
  30. FLEX to is prohibited when?
    • Runway is contaminated
    • Windshear advisories are in effect
    • Runway performance doesn’t allow for FLEX to
  31. Do Wet numbers take into account the increased stopping distance which occurs on wet runways?
    Yes
  32. If you turn the START/STOP to stop in flight, will the engine shutdown?
    Not until thrust lever is idle
  33. When is a cross bleed start used and what happens?
    When APU bleed is not available, bleed air from one engine starts the other
  34. What happens to bleed pressure during a cross bleed start?
    Bleed pressure will drop.

    It is not required to advance the throttle if this occurs
  35. Before apply TO thrust, allow the engines to warm up for a minimum of how many mins?
    2
  36. How long must an engine cool down prior to shutting it down?
    2
  37. What are the EICAS engine limit display markings?
    • Red is Min and Max limits
    • Amber is caution
    • Green is normal
  38. Memory item for ENGINE ABNORMAL START
    # START/STOP. ............ STOP
