FAA Part 107 Drone Practice Test

What is the floor of controlled airspace around Sandpoint Airport?

1. 700 feet MSL

2. 2,831 feet MSL

3. 2,131 feet AGL

4. 1,500 feet AGL

The correct answer is: 2,831 feet MSL

The floor of controlled airspace around Sandpoint Airport is specified as 2,831 feet MSL (Mean Sea Level). This altitude indicates the vertical limit at which drone operators must maintain their operations outside of controlled airspace, where specific regulations and air traffic control protocols apply. Knowledge of these altitudes is critical for drone pilots to ensure safe flight operations and to avoid entering airspace that could conflict with manned aircraft. Controlled airspace is typically structured into different classes, each with its own set of rules and regulations, particularly concerning altitude limits and the necessity for communication with air traffic control. The specified floor of 2,831 feet MSL establishes that below this altitude, drone operations could be more constrained, and thus understanding this limit is essential for compliance and safety. Familiarity with such specifications allows drone operators to plan their flights accordingly and ensure they’re flying legally and safely within the airspace system.
