Pretty much everywhere and under every legislation it is mandatory to fly VLOS in the open categories. But why? While I can understand that rule for drones a decade ago, with unreliable video feeds, no safeguards like RTH on signal loss, auto RTH on low battery, obstacle avoidance, lidar and intelligent flight paths etc., I cannot see why this rule still applies to current drones that have all that. Of course I understand how slow rules change, and that they have to address the smallest common denominator, but what is today the real world benefit of actually seeing the drone and its attitude with my bare eyes? I would say that this is the least followed rule anyway. Why not just just set a minimum of safeguard function to create subgroups in the drone classes that are exempt from VLOS? Ya, politics, and a general tendecy to make flying more and more restricted, but surely there must be an actual reasoning behind VLOS.
Obviously applies to pretty much everywhere as well, but title format demands region.
