In a loss of braking condition, what is the first corrective action?

• A. Reverse thrust to MAX
• B. Parking brake short and successive applications
• C. A/SKID OFF...ORDER
• D. Brake pedals release

Answer: (D)

When braking action is lost, the first move is to release the brake pedals. This quickly relieves pressure in the brake system, allowing the anti-skid/pressure regulators to reset and preventing further heat buildup or potential wheel lock. With the brakes off, you give the system a chance to reinitialize so braking can be re-applied more effectively and safely, using light, progressive pressure as needed. Reapplying the brakes after the system has reset helps you regain control and determine if braking performance has returned. Reason the other options aren’t the first action: increasing thrust to maximum isn’t a reset of the braking system and can create unintended handling or control issues. Turning anti-skid off removes a critical protection that helps prevent wheel lock, so it’s not a prudent first step. Repeatedly using the parking brake during a loss of braking can cause wheel skidding, wear, or damage and isn’t how you restore normal braking.
