For nonmountainous terrain, what is the minimum altitude?

• A. 1200 feet
• B. 1000 feet
• C. 1800 feet
• D. 900 feet

Answer: (B)

Minimum altitude is set to guarantee enough clearance from terrain and obstacles, and it changes with the type of terrain you’re flying over. In flat, nonmountainous areas, you should be at least 1000 feet above the highest obstacle or terrain in the vicinity. That’s why 1000 feet is the minimum for nonmountainous terrain—the lower numbers wouldn’t guarantee safe clearance, and higher numbers aren’t the required minimum for this terrain category. In mountainous areas, the standard is higher to account for taller terrain, typically increasing the minimum clearance above the highest obstacle.
