### The C-17A max design zero fuel weight is _________.

• A.

585,000

• B.

586,000

• C.

170,900

• D.

447,400

D. 447,400
Explanation
The correct answer for the max design zero fuel weight of the C-17A is 447,400. This weight refers to the maximum weight of the aircraft without any fuel on board. It includes the weight of the aircraft structure, engines, systems, and payload, but excludes the weight of the fuel. This value is important for determining the maximum payload capacity of the aircraft.

### To override the #2 and #3 hydraulic aux. pumps for an auto shutdown due to low quantity or overheat, _________.

• A.

Press and hold appropriate Aux pump switch for 5 seconds.

• B.

Press and hold XFER pump switch for 5 seconds

• C.

Press and hold appropriate Aux pump switch for 3 seconds

• D.

Press and hold XFER pump switch for 3 seconds

A. Press and hold appropriate Aux pump switch for 5 seconds.
Explanation
To override the #2 and #3 hydraulic aux. pumps for an auto shutdown due to low quantity or overheat, the correct action is to press and hold the appropriate Aux pump switch for 5 seconds. This will override the auto shutdown and keep the pumps running.

### An automatic shut down override switchlight provides a means to override all APU ECU automatic shutdown signals except _________.

• A.

Over temperature

• B.

Low fuel inlet pressure

• C.

High oil temperature

• D.

Indicated fire or overspeed

D. Indicated fire or overspeed
Explanation
The automatic shut down override switchlight allows for the manual override of automatic shutdown signals from the APU ECU, except in the case of an indicated fire or overspeed. In these situations, it is crucial to immediately shut down the APU to prevent further damage or danger. The override switchlight provides a means to override other shutdown signals such as over temperature, low fuel inlet pressure, and high oil temperature, but it does not override the shutdown signals for fire or overspeed.

### When the APU alert start feature is used, there will be no _______ until the battery bus is powered.

• A.

Fuel flow

• B.

Available power

• C.

Fire detection or protection

• D.

Emergency exit lights

C. Fire detection or protection
Explanation
When the APU alert start feature is used, there will be no fire detection or protection until the battery bus is powered. This means that the fire detection and protection systems will not be operational until the battery bus is activated, which could potentially pose a safety risk in case of a fire. It is important to ensure that the battery bus is powered before relying on the fire detection or protection systems.

### The Battery Direct Bus, the Battery Bus, the AC and DC Emergency Buses, and the AC and DC Transfer Buses comprise the ______.

• A.

Electrical power system

• B.

Battery power system

• C.

External power system

• D.

Emergency power system

D. Emergency power system
Explanation
The Battery Direct Bus, the Battery Bus, the AC and DC Emergency Buses, and the AC and DC Transfer Buses are all components of the emergency power system. This system is responsible for providing power in case of an emergency or failure in the main power system. It ensures that critical functions and equipment can continue to operate even when the main power source is unavailable or compromised.

### Flight rules governing cargo-passenger aircraft require immediate descent to below ________ feet altitude upon complete loss of cabin pressurization.

• A.

10,000

• B.

15,000

• C.

20,000

• D.

25,000

D. 25,000

### If the APU is started and the AVAIL light does not illuminate, the ____ must be cycled from ON to RESET to ON.

• A.

BATT switch

• B.

APU PWR switch

• C.

EMERG PWR switch

• D.

B. APU PWR switch
Explanation
If the APU is started and the AVAIL light does not illuminate, it indicates that there may be an issue with the APU power supply. To resolve this issue, the APU PWR switch must be cycled from ON to RESET to ON. This will reset the power supply and allow the AVAIL light to illuminate, indicating that the APU is now available for use.

### If the Ground Operations Power source is the APU only, the battery switch must be in the ___ position.

• A.

APU

• B.

OFF

• C.

STND BY

• D.

ON

D. ON
Explanation
When the Ground Operations Power source is the APU only, the battery switch must be in the "ON" position. This is because the APU (Auxiliary Power Unit) is responsible for providing electrical power to the aircraft systems when the engines are not running. Therefore, the battery switch needs to be in the "ON" position to ensure that the APU can draw power from the battery when needed.
