UNDERSTANDING PCAS12
The detection window surrounding your aircraft in flight can best be visualized by imagining a “Bubble of Awareness”
surrounding your aircraft. XRX will display any aircraft within this detection window. The “bubble of awareness” can be
shaped to meet the needs of your current flying situation.
The width of the bubble represents and is defined by range; the height is defined by altitude. Both the altitude limits and
range limits can be set independently of each other by the pilot.
