How much room is needed for a 180 Degree Turn?

• A. 75 Feet
• B. 70 Feet
• C. 80 Feet
• D. 65 Feet

Answer: (A)

To perform a 180-degree turn on the ground, you must have enough space for the aircraft to describe a full turning arc without its wings or tail sweeping into obstacles. The required space is essentially the turning diameter—the distance across the circle the aircraft follows during the turn. For a CRJ-550, the turning radius is about 37.5 feet, so the full 180-degree sweep needs roughly 75 feet of clearance. This ensures the wingtips and tail stay clear of surrounding pavement, markings, and any nearby equipment throughout the maneuver. While you could imagine needing more space in tighter conditions, 75 feet represents the standard minimum needed for a safe, complete 180-degree ground turn.
