What is the minimum distance to keep from obstructions when taxiing without a wing walker?

The recommended minimum distance to maintain from obstructions while taxiing without a wing walker is 25 feet. This distance is crucial to ensure safety and prevent any potential collisions with other aircraft, vehicles, or fixed objects. Maintaining this distance gives enough clearance to account for the wingspan of the aircraft and any movement that might occur during taxiing. This safety measure is particularly important in crowded or busy airport environments where obstructions can pose significant risks. By adhering to this guideline, pilots can minimize the chances of accidents and ensure a safer operational environment.
