Understand the terminology of drone ideally called something else however ICAO have not yet define proper terminology as the only document doc 10019 is RPAS (Remotely Piloted Aircraft System) which specifically written for unmanned. Once it is manned then can be called aircraft or ornihopter etc, to eye catch reader, I intentioally name it manned drone, or may be something else once the ICAO or other regulatory authority agreed on new terminology. The idea is to identify various aspects especially when it is Remotely controlled within VLOS (visual line of sight).or C2Link (command and Control) equipped. which operate BVLOS (beyond visual line of sight). I am concern on reliability, controllability if something goes wrong at least have to be overidden by pilot on initial design phase or under experimental category either (fixedwing or rotary wing design concept CS23/CS27) , the issue is certification specification or requirement that is not in place to protect public on safety aspects.
