I would also agree Furious that the report load would be worse than annoying if the system only gave automatic reports every 3 minutes. Not much point in a report about bogeys at 20 miles when you are engaging half a dozen at a thousand yards.
So, a possible solution would be to have both an automatic report mode, and a manual report request mode where there are no reports until the pilot clicks a key to request one. Maximum reporting in auto is a report every three minutes or so. Currently you have to pull up the clipboard to see the DAR, which is similar to a manual request. Or you can leave the clipboard up all the time, which would be like automatic report mode.
The system could also be configured not to continue to report contacts that get within visual range, 3-4 miles?, or that you acknowledge with a click.
Again, I wouldn't envision this system replacing DAR in the MA.
