What is the minimum height above the surface for operations in controlled airspace?

• A. Above 1000 feet AGL
• B. Above 500 feet AGL
• C. Above 1500 feet AGL
• D. Above 2000 feet AGL

Answer: (A)

In controlled airspace, the airspace is actively managed to keep drone operations separate from manned aircraft. The minimum height listed for operations in this space is 1000 feet above the surface because flying at that altitude provides a practical safety buffer from most manned traffic and complex approach/departure paths. Lower altitudes would typically require explicit airspace authorization and a defined plan, while higher altitudes can be permitted with authorization but aren’t the minimum. If you need to operate lower than 1000 feet, you’d pursue the appropriate authorization or waivers and follow the specific airspace procedures.
