Thanks for the replies. So I'm taking it that by messing with QFE, I can get the CCIP display to come up on a non specific target mission.
This question came about with running the Cold Start NTTR mission. At WP3, you have the mock airfield with the MiGs lined up. I've been trying to bomb them, but when following the procedure, the CCIP reticule never appears. So I'll adjust QFE more and see.
