What position should the anti-skid switch be in when the aircraft is ashore?

The correct position for the anti-skid switch when the aircraft is ashore is "On." This is because the anti-skid system is designed to prevent wheel lock-up during braking, allowing for maximum stopping power while maintaining control of the aircraft. When the aircraft is on the ground, particularly during taxiing or takeoff rolls, the anti-skid system becomes crucial for maintaining stability and preventing accidents caused by skidding.

When the anti-skid switch is on, the system is actively monitoring wheel speed and automatically modulating braking force to avoid any conditions that could lead to wheel lock. This allows for a more controlled and safer operation of the aircraft while taxiing or preparing for takeoff on the ground. Therefore, it's essential to keep the anti-skid system engaged when the aircraft is ashore to ensure safety and control during ground operations.
