### From which tanks will fuel gravity feed ?

• A.

Outer cell of the wing tanks , inner cell of the wing tanks , and / or center tank.

• B.

Inner cell of the wing tanks , and center tank.

• C.

Outer cell of the wing tanks , and inner cell of the wing tanks .

C. Outer cell of the wing tanks , and inner cell of the wing tanks .
Explanation
Fuel gravity feed occurs from the outer cell of the wing tanks and the inner cell of the wing tanks. This means that fuel can flow naturally from these tanks without the need for a pump or additional assistance. The center tank is not mentioned as being part of the fuel gravity feed system, so it does not contribute to the flow of fuel in this manner.

Rate this question:

• 5.

### What precaution should you observe when gravity feeding fuel ?

• A.

Operate the aircraft bellow 15,000 feet.

• B.

Use center tank first.

• C.

Open the crossfeed when above FL250.

A. Operate the aircraft bellow 15,000 feet.
Explanation
When gravity feeding fuel, it is important to operate the aircraft below 15,000 feet. This precaution is necessary because gravity feeding relies on the force of gravity to transfer fuel from the tank to the engine. At higher altitudes, the reduced atmospheric pressure can affect the fuel flow and potentially disrupt the gravity feeding process. Therefore, operating the aircraft below 15,000 feet ensures a consistent and reliable fuel transfer.

Rate this question:

### Which of the following would cause the fault light to illuminate on the MODE SEL push button ?

• A.

Fuel is being burned out of sequence.

• B.

Crossfeed push button is ON.

• C.

Center tank pumps do not stop after slat extension.

A. Fuel is being burned out of sequence.
Explanation
If fuel is being burned out of sequence, it means that the fuel is not being burned in the correct order or sequence. This can lead to issues with the engine performance and can potentially cause damage to the engine. The fault light on the MODE SEL push button would illuminate to indicate that there is a problem with the fuel burning process.

Rate this question:

### During normal operation when should the fuel transfer valves open ?

• A.

When low level is sensed in either inner wing cell .

• B.

When a low level is sensed in either outer wing cell.

• C.

When a low level is sensed in the center tank.

A. When low level is sensed in either inner wing cell .
Explanation
The fuel transfer valves should open during normal operation when a low level is sensed in either inner wing cell. This means that when the fuel level in either of the inner wing cells becomes low, the valves will open to allow fuel transfer from other tanks to maintain a sufficient fuel supply. This ensures that the aircraft has a balanced and continuous fuel flow for optimal performance and safety.

Rate this question:

• 8.

### The wing fuel transfer valves are :

• A.

Are electrically held closed.

• B.

Manually controlled and open when the MODE SEL push button is selected to MAN.

• C.

Open automatically at the start of the refueling .

A. Are electrically held closed.
Explanation
The wing fuel transfer valves are electrically held closed, meaning that they are kept closed by an electrical mechanism. This implies that they will remain closed unless an electrical signal is received to open them. The other options mentioned, manual control and automatic opening during refueling, are not applicable to the wing fuel transfer valves in this case.

Rate this question:

• 9.

### The APU fuel system :

• A.

Obtains fuel from either center tank pump.

• B.

Uses it´s own dedicated DC powered fuel pump.

• C.

Obtains fuel from the left fuel manifold via the left side fuel pumps or if needed the APU fuel pump.

C. Obtains fuel from the left fuel manifold via the left side fuel pumps or if needed the APU fuel pump.
Explanation
The APU fuel system obtains fuel from the left fuel manifold via the left side fuel pumps or, if necessary, from the APU fuel pump. This means that the APU can draw fuel from the left fuel manifold, which is connected to the left side fuel pumps. However, if additional fuel is required or if there is a problem with the left side fuel pumps, the APU can also use its own dedicated DC powered fuel pump to obtain fuel.

Rate this question:

### The FAC´S primary control which control surface ?

• A.

Elevator.

• B.

Rudder.

• C.

Aileron .

B. Rudder.
Explanation
The primary control surface controlled by the FAC (Flight Augmentation Computer) is the rudder. The rudder is an aircraft control surface located on the vertical tail fin and is responsible for controlling the yaw motion of the aircraft. The FAC, which is a computer system, provides inputs to the rudder to ensure proper aircraft stability and control during flight.

Rate this question:

• 15.

### If both FAC´S fail ,what happens to the rudder limiter ?

• A.

It immediately assumes the low speed position .

• B.

It freezes at its present position and assumes the low speed position when flaps 1 are selected.

• C.

Maximum rudder deflection can be obtained after slats extended.

B. It freezes at its present position and assumes the low speed position when flaps 1 are selected.
Explanation
When both FACs (Flight Augmentation Computers) fail, the rudder limiter freezes at its current position. This means that it will remain in its current position and will assume the low-speed position when flaps 1 are selected. The rudder limiter is a safety feature that limits the maximum deflection of the rudder based on the aircraft's speed and configuration. In the event of a FAC failure, the rudder limiter will not be able to adjust its position dynamically and will remain in its current position until flaps 1 are selected, at which point it will assume the low-speed position.

### Mechanically backed up control surfaces :

• A.

Are mechanically connected to the cockpit controls.

• B.

Required hydraulic power for actuation .

• C.

Both A and B .

B. Required hydraulic power for actuation .
Explanation
The correct answer is "Required hydraulic power for actuation." Mechanically backed up control surfaces are control surfaces that can be operated manually in case of hydraulic system failure. This means that they are mechanically connected to the cockpit controls and do not rely solely on hydraulic power for actuation. Therefore, option A, "Are mechanically connected to the cockpit controls," is incorrect. Option B, "Required hydraulic power for actuation," is the correct answer as it accurately describes the function of mechanically backed up control surfaces.

Rate this question:

• 18.

### Which of the following will automatically reset after landing ?

• A.

Rudder trim.

• B.

THS.

• C.

Both A and B.

B. THS.
Explanation
The THS (Trimable Horizontal Stabilizer) is a control surface on an aircraft that can be adjusted to change the pitch trim. It is designed to automatically reset to a neutral position after landing. On the other hand, the rudder trim is used to adjust the yaw trim and it does not automatically reset after landing. Therefore, the correct answer is THS.

Rate this question:

• 19.

### Which of the following statements are correct concerning the side stick takeover push button ?

• A.

If the takeover push button is depressed for more than 40 seconds , the onside system will retain priority after the push button is realeased.

• B.

The last pilot to depress the push button has priority.

• C.

Both A and B

C. Both A and B
Explanation
If the takeover push button is depressed for more than 40 seconds, the onside system will retain priority after the push button is released. This means that even after releasing the push button, the system that was initially in control will continue to have priority. The second statement states that the last pilot to depress the push button has priority. This means that whichever pilot was the last to press the button will have control over the system. Both statements A and B are correct.

Rate this question:

• 20.

### Which of the following control surfaces can be mechanically controlled ?

• A.

Speed brakes and flaps.

• B.

THS and flaps

• C.

THS and rudder.

C. THS and rudder.
Explanation
The correct answer is THS and rudder. The THS (Trimmable Horizontal Stabilizer) and rudder are control surfaces that can be mechanically controlled. The THS is used to control the pitch of the aircraft, while the rudder is used to control the yaw. Speed brakes and flaps, on the other hand, are not mechanically controlled surfaces but are instead operated hydraulically or electrically.

Rate this question:

• 21.

### Mechanically backed up control surfaces ?

• A.

Are mechanically connected to the cockpit controls .

• B.

Require hydraulic power for action.

• C.

Both A and B .

B. Require hydraulic power for action.
Explanation
The correct answer is "Require hydraulic power for action." This means that the control surfaces, which are mechanically backed up, need hydraulic power in order to move or function properly. This suggests that the control surfaces are not solely reliant on mechanical connections to the cockpit controls, but also require hydraulic power for their operation.

Rate this question:

• 22.

### Which of the following statements are correct concerning the side stick takeover push button?

• A.

If the takeover push button is depressed for more than 40 seconds . the onside system will retain priority after the push is released.

• B.

The last pilot to depress the push button has priority.

• C.

Both A and B

C. Both A and B
Explanation
If the takeover push button is depressed for more than 40 seconds, the onside system will retain priority after the push is released. This means that if the button is held down for more than 40 seconds, the system will continue to prioritize the onside pilot even after the button is released. Additionally, the statement that the last pilot to depress the push button has priority is also correct. This means that whichever pilot presses the button last will have control over the aircraft. Therefore, both statements A and B are correct.

Rate this question:

### When ground spoilers deploy automatically :

• A.

All ten spoilers panels fully deploy .

• B.

Four spoiler panel on each wing deploy.

• C.

All ten spoiler panels deploy half way.

A. All ten spoilers panels fully deploy .
Explanation
When ground spoilers deploy automatically, all ten spoiler panels fully deploy. This means that all of the spoiler panels on the aircraft, including the four panels on each wing, extend fully to their deployed position. There is no mention of the spoiler panels deploying halfway or only four panels deploying, indicating that the correct answer is that all ten spoiler panels fully deploy.

Rate this question:

### Which of the following controls and monitors flaps and slats ?

• A.

Wing tip brakes.

• B.

One slat flap control computer (SFCC)

• C.

Two slat flap control computers (SFCC´s )

C. Two slat flap control computers (SFCC´s )
Explanation
The correct answer is "Two slat flap control computers (SFCC's)". These computers are responsible for controlling and monitoring the flaps and slats on an aircraft. Flaps and slats are movable surfaces on the wings that help to increase lift and improve the aircraft's performance during takeoff and landing. The SFCC's receive inputs from various sensors and adjust the position of the flaps and slats accordingly to optimize the aircraft's aerodynamic characteristics. Having two SFCC's provides redundancy and ensures that the flaps and slats can still be controlled even if one of the computers fails.
