When the engine bleed air valve is open.

Correct! Wrong!

What does the ENG FUEL VALVE L EICAS message mean?

Both the spar and the engine fuel valves on the left engine are commanded to the same position.

The engine fuel valve on the left engine is closed.

The spar or engine fuel valve on the left engine has not reached its commanded position.

The fuel/oil heat exchanger valve is not functioning.

Correct! Wrong!

What does the ENG OIL PRESS R EICAS message mean?

Engine oil pressure is high.

Engine oil pressure is low.

Engine oil temperature is high.

Engine oil temperature is low.

Correct! Wrong!

With the engine EECs manually selected to the alternate mode, which statement is true?

Positioning the thrust levers to the full forward position will cause the engine limit to be exceeded.

The auto throttle automatically disengages.

The EEC schedules N2 as a function of thrust lever position.

Both engine EECs are now in the soft alternate mode.

Correct! Wrong!

The EICAS caution message ENG FAIL (L or R) is displayed if an engine unexpectedly decelerates to less than idle speed.

True.

False.

Correct! Wrong!

The EECs do not control thrust limits during reverser operation.

True.

False.

Correct! Wrong!

The EECs also control thrust limits during reverser operation.

What does the ENG OIL TEMP L EICAS message mean?

Engine oil pressure is low.

Engine oil pressure is high.

Engine oil temperature is high.

Engine oil temperature is low.

Correct! Wrong!

What does the ENG REV LIMITED R EICAS message mean?

The right engine reverse thrust indication is not valid

The right engine reverser will provide maximum reverse thrust for a limited time

The right engine reverser will not deploy or will be limited to idle

The right engine reverser will not deploy.

Correct! Wrong!

What powers the left engine thrust reverser?

Left hydraulic system.

Centre hydraulic system.

Right engine bleed air.

Left engine bleed air.

Correct! Wrong!

What is auto-relight?

Auto-relight provides hung start protection by deactivating the ignitor.

Auto-relight provides flameout protection by activating the auto start system.

Auto-relight provides flameout protection by activating both ignitors.

Auto-relight opens the start valve automatically if the engine fails to start.

Correct! Wrong!

If the required signals are not available to operate in the normal mode, the EEC automatically uses the alternate mode. In the alternate mode, the EEC schedules N1 as a function of thrust lever position.

True.

False.

Correct! Wrong!

Where is engine oil quantity displayed?

There is no flight deck display for engine oil quantity.

The secondary engine indications.

The status display.

The primary engine indications.

Correct! Wrong!

The EGT indication has a maximum continuous limit represented by a red band.

True.

False.

Correct! Wrong!

The EGT indication has a maximum continuous limit represented by an amber band. The maximum continuous limit does not apply during takeoff or go–around.

Which statement is true concerning the alternate EEC mode?

Engine thrust limit protection is provided in both the normal and hard alternate modes.

In the hard alternate mode, the EEC used N2 as the controlling parameter.

Overspeed protection is not available in the hard alternate mode.

If a fault occurs in the normal mode, control is automatically transferred to the soft alternate mode.

Correct! Wrong!

Can Thrust over-boost occur in EEC Alternate mode when the thrust levers are in full forward position?

No.

Yes.

Correct! Wrong!
