The minimum distance to remain away from the edge of all taxiways during preflight checks is?

The minimum distance to remain away from the edge of all taxiways during preflight checks is 5 feet. This distance is established to ensure safety by minimizing the risk of accidents or incidents that can occur if personnel or equipment get too close to moving aircraft or vehicles on the taxiways. By maintaining this 5-foot separation, individuals conducting preflight checks can perform their responsibilities effectively while ensuring they are at a safe distance from potential hazards associated with ground operations. This safety standard is important to protect both personnel and equipment, reinforcing the importance of adhering to established safety protocols in aviation environments.
