[p7p8]

1. Add approach trigger attached to target
- on page 2 select object: player submarine
- on page 3 set duration for long time (ex: 10 hours)
- on page 3 set radius 20 nmi

2. Make second "automatic" trigger
- on page 2 check "Use Doctrine Language"
- on page 3 select "FirstFailedCriteria" for first (approach) trigger

3. Make attached destination trigger for tracked sub
- on page 3 check "Use Doctrine Language"
- on page 3 set radius (ex: 2 nmi)
- on page 4 set NOT CompletedTrigger2

Of course this solution doesn't test sonar detection. Its only for testing range
