Does the anti-skid operate when braking is available from the accumulator?

• A. No
• B. Yes
• C. Only when wheel speeds are sensed
• D. Only during manual braking

Answer: (A)

Anti-skid needs active hydraulic pressure that the anti-skid control unit can modulate to prevent wheel lock. When braking is available only from the accumulator, the hydraulic pressure is stored and cannot be dynamically controlled by the anti-skid system. The accumulator can apply braking for a short time, but it cannot provide the modulated pressure changes the ASCU requires to prevent wheel slip. So, anti-skid is not operational in that scenario.
