What is the maximum altitude a drone can fly above the ground in uncontrolled airspace without FAA authorization?

• A. 200 ft
• B. 400 ft
• C. 600 ft
• D. 800 ft

Answer: (B)

In uncontrolled airspace, you can fly a small drone up to 400 feet above the ground without FAA authorization. This limit keeps operations in the lower airspace where there’s typically less manned traffic, reducing the risk of conflicts with airplanes and helicopters. If you need to fly higher, you must obtain FAA authorization or a waiver, or operate in airspace where higher limits are allowed. The other altitudes listed exceed or fall short of the standard limit for unapproved operations, so 400 feet is the correct ceiling.
