Which of the following is NOT a general rule for drone flying?

The statement "Fly at no more than 200 mph" represents a guideline that is not typically part of the general rules for drone operation. In practice, most regulations do not specify an exact maximum speed for flying drones; instead, they emphasize safety and adhering to altitude limits and operational practices. Common guidelines concern maintaining a visual line of sight, yielding to other aircraft, and avoiding flying directly over people, particularly in crowded areas, to ensure safety and compliance with aviation regulations. These rules are designed to prevent accidents and ensure that drone operations are conducted responsibly within the broader airspace system. Consequently, because speed limits are not uniformly established or enforced in drone operations, this choice stands out as not being a standard rule for flying drones.
