What is the requirement for the area within 200 feet of taxiway centerlines?

The requirement for the area within 200 feet of taxiway centerlines being free of obstacles is crucial for ensuring safe aircraft movement. This distance is a safety zone designed to minimize the risk of collisions and maintain clear paths for aircraft. If obstacles were present in this zone, they could pose a significant hazard during taxiing operations when aircraft are maneuvering at lower speeds and in close proximity to other vehicles and personnel. By ensuring this area is clear, the likelihood of accidents decreases, promoting safer airfield operations.

In contrast, marking the area with cones, fencing it off, or posting warning signs would not provide the same level of safety as maintaining a clear zone. While these measures can help in certain situations, they do not effectively eliminate the potential for obstruction-related incidents.
