In regard to incorporating FLIR into nav, I recall a night flight with a UK police airwing where the crew was given location of the job, which was identified with address and as being near a local power station cooling tower. As we took off the observer, new to the role and to operating FLIR, used FLIR to identify the power station, but was aghast when it became apparent the aircraft was not flying toward it!
A very animated conversation followed. Resolution not helped by having a doc tv crew onboard which was a new experience for the crew. The pilot agreed that the image was the power station but given it was a night flight he said no, he was "sticking to my instruments" and he "had to believe his instruments".
Just as well, as the FLIR had picked up a power station in the next county, rather the one to which they had been dispatched. (another scene to hit the cutting room floor)
