PPI Example

In this example Disable Rule, an Area Check disables another rule. The area is the Radar Area, in blue, and the rule is the Gate Rule. Here, track 166 enters the Radar Approach Area and therefore disables the Gate Rule; a rule which controls access to the Alarm Area (in purple). Track 167 approaches the Alarm Area.

Because the Gate Rule is disabled, track 167 does not trigger an alarm by breaking a rule in the Alarm Area. 

However, the Gate Rule was only disabled for 1 minute. Therefore, nine tracks (on identical paths to 167) and 60 seconds later, the Gate Rule is enabled and track 176 now breaks the rule and triggers an alarm in the Alarm Area.
