A/SKID automatically deactivate at what ground speed?

A/SKID automatically deactivate at what ground speed?

• A. 10 kt
• B. 15 kt
• C. 19 kt
• D. Groundspeed less than 20 kt

Answer: (D)

Anti-skid braking relies on wheel-speed sensors to modulate brake pressure and prevent wheel lock. At very low ground speeds, braking actions can be unpredictable and the system isn’t needed for taxiing. To avoid nuisance corrections during slow speeds, the A/SKID is automatically deactivated when ground speed drops under 20 knots. Once you exceed 20 knots, the anti-skid protection engages again and helps control braking. So the intended threshold is that the system goes inactive at speeds less than 20 knots.
