Joint Analysis System

Any planned DCA flight which doesn’t have a scheduled orbit, launch time or TOT is on alert. So which ones are Alert 1 and which are Alert 2? There’s really no easy way to tell, though ATO instruction numbers may provide a hint. Since the Alert 1 flights are planned first, followed by scheduled DCA flights (Specified or Block), and finally followed by Alert 2, the first group of ATO instruction numbers will be Alert 1, followed by groupings for planned DCA flights, then the remaining Alert 2’s.
