APKWS can be used to engage airborne targets with TPOD in AG or AA mode nothing stopping you. Only thing can't do is have the HUD in AA mode with APKWS selected, it reverts back to CCIP mode when selecting the rockets. Not sure if there's a way around this although it's easy enough to switch back to AA mode.
The HMCS display is always right in the middle of your screen, it does not actually move with the headtracker. The more your head moves physically away from the center of the screen the more difficult it can be to use. For widescreen and ultrawide displays in particular it can be annoying for some. What we need is a way to "uncage" the HMCS display from the center of the screen and have it move independently of screen center and in sync with the headtracker instead. This feature has been asked for a few times, but there's no way to do it today that I know of.
A couple things you can do:
1) Increase the sensitivity of your headtracker so you are physically moving your head less to get the same range of virtual head movement. This keeps your head more toward the center of the screen when you're looking around which makes it easier to use the HMCS. Downside is the increased headtracking sensitivity comes with its own problems.
2) Another thing you can do is increase the size of the HMCS display "box" a little bit I find this very helpful and highly recommend it. To do that you'll need to make a little tweak to the Scorpion HMCS .lua file make sure you save a backup of the file if you go this route!!!
File to update is HMCS_definitions.lua located in your main DCS install folder, here's where mine is:
C:\Program Files\Eagle Dynamics\DCS World\Mods\aircraft\A-10C_2\Cockpit\Scripts\Scorpion_HMCS\Indicator\HMCS_definitions.lua
The two values you want to change in this file are in bold here:
HMCS_horizontal_sz_mil = 26 * degToMil
HMCS_vertical_sz_mil = 20 * degToMil
I change the above to the following values to increase the HMCS display box to 1.5x of default size and still maintain the correct 13:10 aspect ratio.
HMCS_horizontal_sz_mil = 39 * degToMil
HMCS_vertical_sz_mil = 30 * degToMil
I've experimented with larger sizes, you can size it to fill the whole screen if you want, but go too big and there are some drawbacks. Things like occlusion for example get funky if make it too big. I find the small tweak to 1.5x is just right for me.
Good luck
