I’m holding off judgement until the first weekend of January. I then plan to ask multiple pilots at the 76th Ops Desk Saturday morning when I meet with them to discuss the flying day their opinion on the HUD in DCS with pictures. personally I don’t recall having any issue seeing info in the HUD while performing Ops Checks over my career but I’ve also been in Production now for 5 years (meaning I run the flightline now).
Then on Sunday I’m flying the A-10C simulator at Moody AFB, this will be my second time flying this simulator and I know for a fact that has zero issues seeing the entire HUD display. This also leads me to believe that if truly truncated in the real jet they would have the same in the simulator.
Lastly the below picture Wags posted is not from the pilots eye view. That view would be looking up slightly from the level of my chest when I sit in the cockpit.
This one is closer but IMO is a little higher than eye level.
