The FAA will soon release new rules on the use of drones in the US, and they might be more restrictive than the current ones, potentially making the use of a flying robot much more difficult. Drone pilots will need a license, will only be able to fly during the day, and can only operate below 400 feet, and in the operator’s line of sight, according to a Wall Street Journal report published on Monday. The FAA is reportedly also going to group all unmanned aerial vehicles under these rules, meaning that flying a small toy drone will be subject to the same restrictive rules as flying a bigger commercial one.
