Q

If AUTORELIGHT is displayed above N2: [8.70.10]

A
  • Both igniters are running in the continuous condition.
  • The fuel control switch is in RUN and engine speed has decayed to below idle.
17
Q

The thrust ramping feature compensates for high stress loads due to crosswinds or low groundspeeds. What effect does this have on engine operation? [8.70.10]

A

Maximum T/O thrust may not be reached until 65 KIAS.

18
Q

Which statement is correct regarding APU operation? [8.70.30]

A

Electrical power is available when at or below 43,100 ft.

19
Q

When the reverse thrust levers are moved aft to the interlock position, the autothrottles disengage and the auto speed brakes, if armed, deploy. [8.70.10]

True or False?

A

True.

20
Q

Regarding the Engine Oil System: [8.70.10]

A

A. There is no minimum oil quantity limit for operating the engine in flight.
B. Oil is pressurized by an engine-driven oil pump.
C. Minimum oil quantity prior to start is 18 quarts.
D. All the above.

21
Q

When the APU LIMIT EICAS message is displayed: [8.70.50]

A

An APU limit has been exceeded.

22
Q

With the EECs operating in the normal mode, what action will provide maximum available thrust? [8.70.10]

A

Manually positioning the thrust levers to the full forward position.

23
Q

Which statement is TRUE concerning the hard alternate EEC mode? [8.70.10]

A

In the hard alternate mode, the EEC uses N1 as the controlling parameter.

24
Q

Thrust control malfunction accommodation (TCMA) can automatically shut down an engine to protect against idle thrust asymmetry conditions while on the ground. [8.70.10]

True or False?

A

True.

25
Q

In the attended mode, which of the following APU faults allow the APU to continue to operate? [8.70.30]

A

A. High EGT.
B. High Oil Temperature.
C. Low Oil Pressure.
D. All of the above.

26
Q

How many starter/generators are available to start the APU? [8.70.30]

A

Two electric. Only the Right S/G is available for a battery start.

27
Q

The momentary illumination of the APU FAULT during start is indicative of a non- normal condition and the APU should be manually shut down and investigated. [8.70.40]

True or False?

A

False.

28
Q

In flight or on the ground with no engines running or being started, the APU is operating in the unattended mode. [8.70.30]

A

False.

29
Q

The ENG display switch on either DSP, when selected: [8.70.10]

A

Adds or removes the Secondary Engine instruments on EICAS below the Primary instruments.

30
Q

In what Flight Control mode(s) is Thrust Asymmetry Protection (TAP) available? [8.70.10]

A

Normal.

31
Q

Simultaneous engine start requires: [8.70.10]

A

Using both APU generators as the power source.

32
Q

An engine failure during takeoff prior to V1 will generate a time critical warning ENGINE FAIL, in conjunction with illumination of the Master Warning lights and a Warning siren. [8.70.10]

True or False?

A

False.

33
Q

During single engine takeoff or go-around, the EEC may reduce thrust on the operating engine to maintain the required climb performance. This feature is called: [8.70.10]

A

Thrust Asymmetry Protection (TAP).

34
Q

The APU battery is designed to support —- consecutive start attempts. [8.70.30]

A

2

35
Q

The APU is designed to be started and operating in flight at altitudes up to [8.70.30]

A

43,100

36
Q

Starting both engines simultaneously may be accomplished with only one APU starter/generator. [8.70.10]

True or False?

A

False.

37
Q

If an engine fails while in flight, the autostart system will attempt: [8.70.10]

A

Continuous restarts until the engine is started or the fuel control switch is selected to CUTOFF.

38
Q

Thrust Asymmetry Protection (TAP) is automatic and can be verified by: [8.70.10]

A

Observing a thrust reduction on the N1 indicator of the operating engine.

39
Q

Which of the following is true with regard to loss of three starter generators (SGs) in flight? [8.70.30]
