Test cases: 1. Target is not threatened. The IP should be placed on a direct heading from the origin to the target at the max ingress distance, or very near the origin airfield if the airfield is closer to the target than the IP distance. 2. Unthreatened home zone, max IP between origin and target, safe locations available for IP. The IP should be placed in LAR at the closest point to home. 3. Unthreatened home zone, origin within LAR, safe locations available for IP. The IP should be placed near the origin airfield to prevent backtracking more than needed. 4. Unthreatened home zone, origin entirely nearer the target than LAR, safe locations available for IP. The IP should be placed in LAR as close as possible to the origin. 5. Threatened home zone, safe locations available for IP. The IP should be placed in LAR as close as possible to the origin. 6. No safe IP. The IP should be placed in LAR at the point nearest the threat boundary.
