Aviation Landing Gear Quiz: Mastering Aircraft Safety and Control

1. Which of the following components are typically part of an aircraft's landing gear system?

Struts and shock absorbers

Brakes and tires

Hydraulic actuators and safety valve

All of the above

All of the components mentioned in the options are typically part of an aircraft's landing gear system. Struts and shock absorbers are essential for absorbing the impact during landing and providing stability to the aircraft. Brakes and tires are necessary for slowing down and stopping the aircraft on the ground. Hydraulic actuators are used to control the movement of the landing gear, and safety valves ensure the proper functioning and safety of the system. Therefore, all of these components are typically included in an aircraft's landing gear system.

2. What is the purpose of the mechanical visual gear down lock indicators in an aircraft's cockpit?

To display tire pressure

To indicate gear position

To control the flaps

To activate the anti-skid

The purpose of the mechanical visual gear down lock indicators in an aircraft's cockpit is to provide a clear indication of the position of the landing gear. This is important for the pilot to ensure that the landing gear is properly extended and locked in place before landing. The indicators allow the pilot to visually confirm the gear position, providing an additional layer of safety during the landing process.

3. When the autobrake operates, it can be disarmed by:

Ground spoilers retraction.

Pressing the Mode pb or losing an arming condition.

Action on 1 pedal in LO, MED or MAX mode.

All of the above.

The correct answer is "All of the above." When the autobrake operates, it can be disarmed by ground spoilers retraction, pressing the Mode pb, or losing an arming condition. This means that any of these actions can disable the autobrake system.

The correct answer is "All of the above." When the autobrake operates, it can be disarmed by ground spoilers retraction, pressing the Mode pb, or losing an arming condition. This means that any of these actions can disable the autobrake system.

4. In case of an emergency, what method can be used to extend the landing gear by gravity?

Engaging the autopilot

Pulling the throttle

Using the hand crank

Activating the APU

In case of an emergency, the method that can be used to extend the landing gear by gravity is using the hand crank. The hand crank is a manual mechanism that allows the pilot or crew to manually lower the landing gear when there is a failure in the normal hydraulic or electrical systems. This method relies on the force of gravity to lower the landing gear, ensuring a safe landing in emergency situations.

5. In flight, with the parking brake set to ON, a message on ECAM shows PARK BRK:

In green

In amber

In blue

In beige.

The message "PARK BRK" on ECAM appearing in amber indicates that the parking brake is set to ON during the flight. The amber color signifies a caution or warning, suggesting that the parking brake may need attention or adjustment. This alert helps the flight crew to be aware of the parking brake status and take necessary actions if required.

The amber color signifies a caution or warning, suggesting that the parking brake may need attention or adjustment. This alert helps the flight crew to be aware of the parking brake status and take necessary actions if required.

6. How many turns are necessary to extend the landing gear by gravity using the handcrank?

Ten turns clockwise

Five turns clockwise

Three turns clockwise

Four turns clockwise

To extend the landing gear by gravity using the handcrank, three turns clockwise are necessary. This indicates that the handcrank needs to be rotated in a clockwise direction for three complete rotations in order to extend the landing gear.

Explanation

To extend the landing gear by gravity using the handcrank, three turns clockwise are necessary. This indicates that the handcrank needs to be rotated in a clockwise direction for three complete rotations in order to extend the landing gear.

7. Which ADIRS's close the safety valve of the green hydraulic supply when speed > 260 kts?

ADIRS 1 and 2

ADIRS 1 and 3

ADIRS 2 and 3

All of these

When the aircraft's speed exceeds 260 kts, ADIRS 1 and 3 close the safety valve of the green hydraulic supply. This action is taken to prevent any potential damage or failure in the hydraulic system due to excessive speed. ADIRS stands for Air Data Inertial Reference System, which is responsible for providing critical information and data to various systems in the aircraft. By closing the safety valve, ADIRS 1 and 3 ensure the hydraulic system remains within safe operating limits during high-speed flights.

8. The braking systems are?

Green with anti-skid, yellow without anti-skid, parking brake.

Green or yellow with anti-skid, yellow without anti-skid, parking brake.

Green with or without anti-skid, yellow without anti-skid, parking brake.

Green with anti-slip, yellow with anti-skid, parking brake.

The correct answer is "Green or yellow with anti-skid, yellow without anti-skid, parking brake." This answer suggests that the braking systems can be either green or yellow and can have anti-skid technology. However, there may be some systems that are yellow without anti-skid. Additionally, all systems have a parking brake.

9. What is the MAX tire speed?

205 kts

195 kts

185 kts

225 kts

The maximum tire speed is 195 kts. This means that the tires of the aircraft should not exceed a speed of 195 knots during operation. Going beyond this speed limit can result in tire failure or other safety hazards.

Explanation

The maximum tire speed is 195 kts. This means that the tires of the aircraft should not exceed a speed of 195 knots during operation. Going beyond this speed limit can result in tire failure or other safety hazards.

10. Are there any mechanical visual gear down lock indicators?

No

Yes

Only 3 are there

2 are present

The given answer "No" suggests that there are no mechanical visual gear down lock indicators. This means that there are no physical indicators in the mechanical system that show whether the gear is locked in the down position or not.
