hmm you’re trying hud/hmd markpoint in NAV mode…
I don’t know is it possible, … there is in manual , probably under Markpoint section, a table in which Mode allows taking which type of markpoint … eg. AA mode 0fly , AG mode - GM markpoint … etc.
See if that helps.
Other then that, yes, in HUD mode need DMS-up to activate HUD targeting , then TMS-up to cursor stabilize , then move cursor over object and again TMS-up to place.
For HMD , after DMS-up , long press TMS-up to switch SOI to HMD , move head then TMS-up over object… not 100% but I did it once or twice to test it , it works.
This means you’ve deleted (or lost) your IFF keys , by turning off IFF mode switch or power loss , or damage. - so no more IFF for you , enter emergency IFF mode
… but friendly AI won’t shoot at you anyway, but also, you can’t identify friendlies anymore.
If you printed IFF keys before mission , there’s a slim chance to make it operating again , if you didn’t … tough luck 🙂
