What the clearance warning control unit monitors

By monitoring these items, the system recognises how the UMS is controlled.
Monitored data can be stored three times; Event 1 (the last), Event 2 (the last but one) and Event 3 (the last but two). To store the forth data, oldest Even 3 will be erased.
