HUD mode SPI question
Hi, when I'm using the Lightening pod to target and then designate a SPI (w TMS fwd long), then when I'm done attacking, I want to go back to steer point SPI. So I set HUD as SOI and do a TMS aft short, the HUD SPI descriptor sometimes says IFFCC and I can't seem to get back to stpt w/o resetting a few modes. It's not a huge issue, I'm just curious as to what's going on when that happens.
Thx!
