_____ prevents tire skidding and ensures maximum braking efficiency.

• A. Anti-skid protection
• B. Traction control
• C. ABS
• D. Brake assist

Answer: (A)

Anti-skid protection keeps tires from skidding during braking by automatically managing brake pressure so the wheels don’t lock up. It uses wheel-speed sensors and a control system to detect when a wheel is decelerating too quickly relative to the others. When lockup is imminent, the system releases brake pressure on that wheel and then gradually reapplies it, cycling as needed. This keeps the tire in contact with the runway surface, preserving steering control and allowing the braking force to stay near the tire–surface friction limit, which gives you the shortest stopping distance and the most effective braking overall.

Traction control focuses on preventing wheel spin during acceleration, not during braking rollout. Brake assist helps applying a strong braking force quickly during emergencies but doesn’t specifically prevent wheel lock. ABS describes the same basic idea of preventing lockup, but in aviation contexts the preventive, friction-keeping function is commonly described as anti-skid protection.
