I can understand what you are saying but you must have that 20-30 sec to land a UAV by your own that shouldn't be a problem.
Another problem is if there's an autoland function for the Grayhawks that the UAV Operator let the UAV land and blocks then entire runway
for other air vehicles and forget what he has done.
That's exactly the problem with the Carrier at the moment that UAV Operators let the Sentinel land and leave it there till a jet requests the UAV Operator
to clear the runway.
Sorry for the bad english.
