True or False?
True.
Regarding the Engine Oil System: [8.70.10]
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.

An APU limit has been exceeded.
With the EECs operating in the normal mode, what action will provide maximum available thrust? [8.70.10]
Manually positioning the thrust levers to the full forward position.
Which statement is TRUE concerning the hard alternate EEC mode? [8.70.10]

How many starter/generators are available to start the APU? [8.70.30]
Two electric. Only the Right S/G is available for a battery start.
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?
False.
In flight or on the ground with no engines running or being started, the APU is operating in the unattended mode. [8.70.30]
False.
The ENG display switch on either DSP, when selected: [8.70.10]
Adds or removes the Secondary Engine instruments on EICAS below the Primary instruments.
In what Flight Control mode(s) is Thrust Asymmetry Protection (TAP) available? [8.70.10]
Normal.
Simultaneous engine start requires: [8.70.10]
Using both APU generators as the power source.
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?
False.
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]
Thrust Asymmetry Protection (TAP).
