The blackfoot has had PIP for a while now and it's the smoothest for the highest detail we've seen. I can't tell you how happy I am to see this especially after the change from having it behind the gun.
It offers the pilot an opportunity to see what the gunner is looking at however it isn't really being used to max capability.. The screen currently being used is x2, almost x3 smaller than the digital display that the gunner uses. Due to this the pilot cannot see in the same detail what the gunner is seeing, they may miss things and by comparison of clarity, you need to press 0 or zoom in to have the same clarity.
If you swap between pilot and co pilot, use take controls and observe what you can see through the co pilot versus the pilot then the pilot can see much better period.
