It's inconsistent. Sometimes it works exactly as expected and you can move the hud cursor and the tgp moves with it. Other times, hud cursor doesn't move. Others, you can move both, but they aren't slaved. I did it over and over again with the exact same steps and got different behavior, seemingly at random.
There should be some method to target within the hud fov, like the old boresight. The current SP, being fixed a specific distance, no matter the roll or pitch of the jet, is virtually useless unless you align your nose, set it, then slew the pod upwards. That's needlessly cumbersome compared to how the Lightening pod works on every other aircraft.
Additionally, if you change the steerpoint, that location you just worked to find is GONE. Unless you WRITE down the coordinates shown on the tgp display and make a new steerpoint with them, there is no way to go back to that location again.
Lat/Long on the display and TTI is nice and all, but the new pod, unless used on a nice fixed steerpoint against stationary targets, is absolute garbage compared to yesterday. That doesn't even touch the issues with adding in the visual changes without giving tuning capabilities to actually have things stand out from the surroundings.
Horrible choices on implementation.
