FAA Ground School Practice Test

What is the minimum safe altitude required for a pilot to operate an aircraft over congested areas, except for takeoff or landing?

1. 500 feet above the highest obstacle

2. 1,000 feet above the highest obstacle within a horizontal radius of 2,000 feet

3. 1,500 feet above ground level

4. 2,500 feet within 5,000 feet of congested areas

The correct answer is: 1,000 feet above the highest obstacle within a horizontal radius of 2,000 feet

The minimum safe altitude required for a pilot to operate an aircraft over congested areas, except for takeoff or landing, is set at 1,000 feet above the highest obstacle within a horizontal radius of 2,000 feet. This regulation is designed to ensure a safe operating distance from structures and people on the ground, minimizing the risk of collisions or accidents. By maintaining this altitude, pilots can better avoid any unforeseen emergencies that may arise and still provide a margin of safety to those below. The requirement specifically emphasizes the height of the highest obstacle, as urban environments often have varying structures, such as skyscrapers, towers, and other buildings that could pose a risk. Additionally, the 2,000-foot horizontal radius is structured to create a buffer for the aircraft, ensuring more room for altitude adjustments in response to any potential hazards. Maintaining this minimum altitude is fundamental for the safety of both the occupants of the aircraft and individuals on the ground in populated areas.
