At what airspeed is anti-skid inoperative on the CRJ 200?

The anti-skid system on the CRJ 200 becomes inoperative at an airspeed of 10 knots. This limitation is crucial for pilots to understand, as it ensures the safe operation of the aircraft during landing and rollout. Below this airspeed, the anti-skid system is designed to disengage due to its reliance on wheel speed data to function effectively.

Once the aircraft is below 10 knots, the potential for skidding increases with a lack of anti-skid protection, particularly during wet or slippery runway conditions. Recognizing this limitation helps pilots to anticipate the handling characteristics of the aircraft as they slow down on landing or taxiing.

The other speeds listed do not represent the point at which the anti-skid becomes inoperative, making them irrelevant in this context. Therefore, knowing that 10 knots is the critical airspeed enhances situational awareness during landing operations.
