Is the anti-skid able to operate when braking is provided by the accumulator?

• A. No
• B. Yes
• C. Only if a wheel is spinning
• D. Only in flight

Answer: (A)

Anti-skid needs a continuous hydraulic pressure source to modulate brake pressure based on wheel-speed signals. That pressure is normally supplied by the hydraulic pumps; the accumulator only provides a finite stored energy reserve for brief braking, not a sustained, controllable pressure source. So when braking is provided solely by the accumulator, there isn’t enough continuous pressure for the anti-skid system to operate, and it cannot function.
