Except when necessary for takeoff or landing, what is the minimum safe altitude for a pilot to operate an aircraft over other than a congested area?

• A. An altitude of 500 ft AGL, except over open water or a sparsely populated area, which requires 500 ft from any person, vessel, vehicle, or structure
• B. An altitude of 1,500 ft AGL
• C. An altitude of 1,000 ft AGL
• D. An altitude of 200 ft AGL

Answer: (A)

The main requirement is to fly at 500 feet above the surface when you’re over areas that aren’t congested. This height gives you a safety margin to handle an engine failure or other problems and to maneuver to a suitable landing spot without risking people or property on the ground.

There is an exception for open water or sparsely populated areas: in those cases you must also maintain at least 500 feet of horizontal separation from any person, vessel, vehicle, or structure. So the safe altitude remains 500 feet, but you add a rule about staying clear of individuals or assets in those lighter-populated areas.

Options that propose higher altitudes aren’t aligned with the general minimum, and flying as low as 200 feet would not provide the required safety buffer.
