How far must an aircraft stay from any person, vessel, vehicle or structure when not over congested areas?

• A. 500 feet
• B. 1,000 feet
• C. 2,000 feet
• D. 3,000 feet

Answer: (A)

The idea being tested is the safety margin you must keep from people and structures on the surface when you’re not over a congested area. The reason 500 feet is the right choice is that regulations require you to stay at least 500 feet away from any person, vessel, vehicle, or structure on the surface when you’re not over a congested area. This buffer gives you room to handle unexpected situations and protects people on the ground from potential hazards. When you are over a congested area, the rules demand a higher level of clearance—typically 1,000 feet above the highest obstacle within a 2,000-foot radius—reflecting the greater risk to densely populated areas.
