Abstract:

The existing surveillance-based air traffic control system has been effective in preventing midair collisions, especially those involving air carrier aircraft. Improvements in this effectiveness can be achieved, in the short-term, thorugh mandatory carriage of altitude-encoding beacon ATCRBS transponders. To achieve the desired major improvements in collision prevention for public air transportation requires the addition of an independent backup capability to the primary ground-based system and a new capability beyond the limits of its surveillance coverage. These can be best achieved in the mid-term by an airborne BCAS system based on the mandatory carriage of altitude-encoding transponders. The BCAS design should permit a longerterm upgrading to the compatible DABS transponder and implementation of IPC in at least the dense traffic areas.
