The A-10 Fuselage components the redistribute loads around cutouts and provide redundant load paths are
- A.
Stingers
- B.
Spars
- C.
Auxillary longerons
- D.
Ribs
Correct Answer
C. Auxillary longeronsExplanation
Auxiliary longerons are fuselage components that help redistribute loads around cutouts and provide redundant load paths. They are additional structural members that run parallel to the main longerons and provide extra support and strength to the fuselage structure. These longerons help to distribute the loads evenly and prevent stress concentrations around cutouts, ensuring the structural integrity of the A-10 fuselage.Rate this question:

To prevent potential tank explosion during combat, the Z-10's integral fuel tanks are filled with
- A.
Rubber
- B.
Ballistic foam
- C.
Polyurethane foam
- D.
Composite materials
Correct Answer
C. Polyurethane foamExplanation
Polyurethane foam is used to fill the integral fuel tanks of the Z-10 helicopter to prevent potential tank explosions during combat. Polyurethane foam is known for its excellent fire resistance and insulation properties. It acts as a barrier between the fuel and the external environment, reducing the risk of ignition and explosion. This foam also helps to absorb impact and reduce the chances of fuel leakage in case of any damage to the tanks. Therefore, filling the fuel tanks with polyurethane foam is an effective safety measure to enhance the combat survivability of the Z-10 helicopter.Rate this question:

The A-10 nose wheel steering is initiated in the commanded direction by the movement of the rudder pedals in conjunction with a steering command signal generated by the
- A.
Steering switch
- B.
Steering collar assembly
- C.
Position transducer potentiometer
- D.
Steering unit
Correct Answer
C. Position transducer potentiometerExplanation
The A-10 nose wheel steering is initiated by the movement of the rudder pedals, which provides the directional input. However, this movement alone is not sufficient to steer the nose wheel. A steering command signal is also required, which is generated by the position transducer potentiometer. This potentiometer measures the position of the rudder pedals and sends a signal to the steering unit, which then activates the nose wheel steering in the commanded direction. The steering switch and steering collar assembly are not directly involved in initiating the nose wheel steering.Rate this question:

If electrical power is lost, the operable A-10 nose wheel steering mode is
- A.
Steering
- B.
Fail-safe
- C.
Auxiliary
- D.
Damper-caster
Correct Answer
D. Damper-casterExplanation
The operable A-10 nose wheel steering mode in the event of electrical power loss is the damper-caster mode. In this mode, the nose wheel steering is controlled by a combination of hydraulic dampers and castering action. The hydraulic dampers provide stability and control, while the castering action allows the nose wheel to freely rotate and follow the direction of the aircraft's movement. This mode ensures that the aircraft can still be maneuvered safely even without electrical power.Rate this question:

- D.
An accumulator
Correct Answer
D. An accumulatorExplanation
In the event of both the left and right hydraulic systems failing, the A-10 relies on an accumulator to provide emergency braking power. An accumulator is a device that stores hydraulic energy, allowing it to be released when needed. In this case, the accumulator would release the stored energy to power the brakes, ensuring that the aircraft can still come to a stop safely even without hydraulic assistance.Rate this question:

- A.
Dual-acting pistons
- B.
Unbalanced pistons
- C.
Balanced pistons
- D.
Tandem pistons
Correct Answer
B. Unbalanced pistonsExplanation
The actuator type A-10 speed brakes use unbalanced pistons. Unbalanced pistons are designed to create an uneven force distribution, which helps in quickly and forcefully retracting or extending the speed brakes.

On the A-10's fire extinguishing system, the fire extinguishing discharge switch is a
- A.
Two-position, single-throw, center-off toggle switch
- B.
Two-position, double-throw, center-off toggle switch
- C.
Three-position, single-throw, center-on toggle switch
- D.
Three-position, double-throw, center-off toggle switch
Correct Answer
D. Three-position, double-throw, center-off toggle switchExplanation
The correct answer is three-position, double-throw, center-off toggle switch. This means that the switch has three possible positions: one in which it is in the center and off, and two other positions in which it can be thrown to either side. The switch is double-throw, meaning it can connect or disconnect two different circuits. In this case, it is used for the fire extinguishing system, so it likely controls the activation and deactivation of the system. The center-off position allows for a neutral state where the system is not active.Rate this question:

The main landing gear strut on the U-2 is constructed of
- A.
Aluminum alloy
- B.
Stainless steel
- C.
Composites
- D.
Titanium
Correct Answer
D. TitaniumExplanation
The main landing gear strut on the U-2 is constructed of titanium. Titanium is known for its high strength-to-weight ratio, making it an ideal material for aerospace applications. It is lightweight, yet strong enough to withstand the forces and stress during landing. Additionally, titanium is highly resistant to corrosion, which is crucial for an aircraft that operates at high altitudes and in various weather conditions. Therefore, using titanium for the main landing gear strut ensures durability, reliability, and optimal performance of the U-2 aircraft.Rate this question:

If total hydraulic failure occurs on the U-2, the number of full brake applications the emergency brake accumulator supplies hydraulic pressure for is
- A.
Three
- B.
Five
- C.
Seven
- D.
Nine
Correct Answer
B. FiveExplanation
The emergency brake accumulator on the U-2 supplies hydraulic pressure for a total of five full brake applications in the event of a total hydraulic failure.Rate this question:

During normal landing gear extension on the U-2, the main landing gear actuator pressure buildup is delayed until the uplock acuator has unlocked the gear by a(n)
- A.
Check valve
- B.
Orifice valve
- C.
Control valve
- D.
Selector valve
Correct Answer
B. Orifice valveExplanation
The correct answer is orifice valve. During normal landing gear extension on the U-2, the main landing gear actuator pressure buildup is delayed until the uplock actuator has unlocked the gear by an orifice valve. This valve restricts the flow of hydraulic fluid, causing a delay in the pressure buildup, which allows the uplock actuator to unlock the gear before the pressure is applied. This ensures that the gear is fully unlocked and ready to extend before the pressure is applied, preventing any potential damage or malfunction during landing.Rate this question:
