Flight is only allowed within visual line of sight of the pilot and/or the observer. Someone has to be watching it at all times when it is flying.
The pilot of a commercial UAS, at a minimum, must be an FAA certified sport pilot. This may change some in the upcoming FAA FAR Part 107 release due to release over the summer.
Flight is not allowed at night.
Flight is not allowed over water.
Flight is not allowed over people.
Flight is not allowed within 5 miles of an airport.
The night time flight limitation seems very significant for security applications. Also, the "within 5 miles of an airport" limitation is more restrictive than a lot of people realize when you take into account how many small regional airports are out there.
Logistical and regulation obstacles certainly exist, there is no denying this. Will these obstacles prevent security robotics from changing the face of our industry? They will not, consequently our council to PSA integrators is to pay attention to robotics as related to security.
Aerial, ground based, marine and sub marine security robotics will change our game. it is not a matter of if but when and in this case, when is not far off.
