The 0.55 pounds (or 250 grams) weight registration threshold for drones is identical in both the Russian and American drone registration laws. Russian law also establishes a minimum of a two-person crew for the drone, which is a step further than the American law. This crew consists of a pilot and an observer, whose job is to watch the drone in flight. The drone pilot has to file flight information, but is allowed to deviate from the flight plan as circumstance requires, so long as they notify the relevant authorities. In addition, the law requires that drone pilots prioritize the safety of manned aircraft.
