Question from the peanut gallery: What sort of visibility or situational awareness does the tower have of proper runway alignment? Other than reports from the crew landing and those waiting (and ducking) on the taxiway? Any thoughts about camera systems lined up with the runway? A plane on proper alignment could be seen as straight on, while one heading for the taxiway would appear to be drifting left.
There is some discussion of using remote ATC for smaller (GA only?) airports. One of the advantages mentioned is that camera feeds sent to the remote facility could provide points of view not available to a traditional tower.
Or would cameras just be another maintenance headache that would end up restricting operations if inop?
