Test on Aircraft Landing Gear Systems

Question 1: Some aircraft wheels are equipped with a fusible plug.

A. Ano

B. Ne

Explanation: The study materials mention 'the fusible plug in some aircraft wheels,' which indicates that certain aircraft wheels are indeed equipped with this component.

Question 2: What must be accomplished before inspecting a wheel brake system for hydraulic leaks?

A. Bleed the air from the system

B. Pressurize the system

C. Check the compensator port

D. Deflate the shock strut completely

Explanation: Before inspecting a wheel brake system for hydraulic leaks, the system must be pressurized.

Question 3: Shuttle valves are incorporated into the main pressure line leading directly to the brake booster.

A. Ano

B. Ne

Explanation: Each brake actuating line in a power brake system incorporates a shuttle valve.

Question 4: The shuttle valve keeps the normal and emergency brake systems connected at all times.

A. Ano

B. Ne

Explanation: The shuttle valve's purpose is to isolate the emergency brake system from the normal brake system, not keep them connected.

Question 5: What is the immediate consequence when emergency brake actuating pressure enters the shuttle valve?

A. The shuttle is systematically moved to the opposite end of the valve.

B. Pressure builds up in the brake lines, causing the brakes to drag.

C. The normal hydraulic brake system actuating line remains open.

D. The emergency brake system is isolated from the normal brake system without any shuttle movement.

Explanation: According to the study materials, 'When emergency brake actuating pressure enters the shuttle valve, the shuttle is systematically moved to the opposite end of the valve.'
