Statement 1: “In case of failure of an anti-skid system the auto-brake system takes over the regulation of the slip ratio”
Incorrect because the anti-skid system is only active if the auto-brake system is active, these are two separate systems. So the auto-brake system on its own cannot take over the regulation of the slip ratio.

Statement 2: “Careful brake application by the pilot in case of anti-skid failure can achieve the same performance as a properly functioning anti-skid system”
Incorrect, a pilot will never reach the same performance as a properly functioning anti-skid system. The anti-skid system senses when a brake starts to skid and will reduce braking pressure to avoid the wheels from skidding, a pilot won’t come close to the same performance.
