What is auto-relight?

Auto-relight provides flameout protection by activating both ignitors.

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

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

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

Correct! Wrong!

What malfunction, during ground start, will cause the auto-start system to abort the start?

Broken fan blade.

Hot start.

High oil pressure.

Low oil pressure.

Correct! Wrong!

How many in-flight starts does the Auto-start system attempt?

Continuous attempts until the engine starts or the pilot moves the engine fuel control switch to CUTOFF.

Correct! Wrong!

What does the ENG REV LIMITED R EICAS message mean?

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

The right engine reverse thrust indication is not valid

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 engine bleed air.

Right engine bleed air.

Centre hydraulic system.

Left hydraulic system.

Correct! Wrong!

What does the ENG OIL TEMP L EICAS message mean?

Engine oil temperature is high.

Engine oil pressure is high.

Engine oil temperature is low.

Engine oil pressure is low.

Correct! Wrong!

When does the EEC select approach idle?

When wing anti-ice is ON.

When the engine bleed air valve is open.

When the flaps are commanded to 25 or greater.

When the flaps are out of the UP position.

Correct! Wrong!

Which statement is true concerning the alternate EEC mode?

Overspeed protection is not available in the hard alternate mode.

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

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

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

Correct! Wrong!

The oil system provides pressurized oil to lubricate and cool the engine main bearings, gears and accessory drives. The oil system also provides automatic fuel heating for fuel system icing protection.

False.

True.

Correct! Wrong!

The EECs do not control thrust limits during reverser operation.

False.

True.

Correct! Wrong!

The EECs also control thrust limits during reverser operation.

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

False.

True.

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.

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.

False.

True.

Correct! Wrong!

When does automatic continuous ignition activate?

When flaps are out of the UP position or engine anti-ice is on.

When the landing gear is down.

When the thrust levers reach idle or the landing gear is down.

When thunderstorms are detected on the weather radar.

Correct! Wrong!

What does the ENG FUEL VALVE L EICAS message mean?

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.

The engine fuel valve on the left engine is closed.

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

Correct! Wrong!

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

Both engine EECs are now in the soft alternate mode.

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

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

The auto throttle automatically disengages.

Correct! Wrong!

Where is engine oil quantity displayed?

The primary engine indications.

There is no flight deck display for engine oil quantity.

The status display.

The secondary engine indications.

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!

Which engine parameters the does the auto-start system not monitor and abort the start sequence?

No N1 rotations.

Starter shaft failure.Hung start.

Oil pressure and temperature.

Hung start.

Correct! Wrong!

The engine failure alert system provides alerts when actual engine performance is less than commanded engine performance during a part of the takeoff and for other phases of flight. A red ENG FAIL is displayed on the PFD if actual thrust is less than commanded thrust during takeoff with airspeed between ______ prior to V1.

50 knots and 2 knots

65 knots and 6 knots.

80 knots and 5 knots.

30 knots and 5 knots

Correct! Wrong!

The PFD display is accompanied by the voice annunciation ENGINE FAIL and the Master WARNING lights illuminating.

The autostart system does not monitor engine oil pressure but it monitors engine temperature.

False.

True.

Correct! Wrong!

The autostart system does not monitor oil pressure and temperature.

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

Yes.

No.

Correct! Wrong!

What does the ENG OIL PRESS R EICAS message mean?

Engine oil temperature is high.

Engine oil temperature is low.

Engine oil pressure is high.

Engine oil pressure is low.

Correct! Wrong!

With auto start ON, when do you move the FUEL CONTROL switch to RUN?

After the engine stabilizes at idle.

After reaching maximum motoring speed.

After 18% N2 has been reached.

After START has been selected on the START/IGNITION selector.

Correct! Wrong!
