I am doing this as RIO, Pilot saw them blinking as well. We would have targets that are 50+ nm out and when TWS auto would target them, they would be blinking. Based on what I read in the manual, they should blink when they are within 8 seconds of impact, see snip from manual below. I feel like I am missing something. Can someone please explain why the contact symbol is blinking when trying to lock them with TWS auto, also when an AM-54 was launched, it would not start a countdown or track the target at all. I would really appreciate some clarity, I hope it is something that I missed when reading the manual.
