What are the minimum altitudes?

• A. 1000 feet in nonmountainous; 2000 feet in mountainous
• B. 2000 feet in nonmountainous; 1000 feet in mountainous
• C. 1500/1500
• D. 500/500

Answer: (A)

Minimum safe altitudes are set to ensure obstacle clearance depending on the terrain. In mountainous areas, you must stay at least 2000 feet above the highest obstacle within 2000 feet of your position. In nonmountainous terrain, the requirement is 1000 feet above the highest obstacle within 2000 feet. These values reflect the greater clearance needed in rugged terrain. The other options don’t match this terrain-based rule, since they either swap the numbers or propose a lower altitude that wouldn’t guarantee sufficient clearance. Remember these are minimums; real-world flying also depends on weather, performance, and airspace rules.
