Now you made me insecure lol. Long time since i was on F4AF, but im sure there was a warning on incoming threats. I know newer F16's have a spherical missile warning system that detects threats all around. Isnt there a warning when a SAM or a AMRAM is locked to you in a F16? Must be, but i just dont remember in what way, sound or visual it was.
Anyway, it cant be all silent and dark when someone locks/fires a missile at you, or pilots wouldnt stand a chance up there. Maybe i didnt get your answer correct either However an incoming threat sound would be great as now (on all original aircrafts in arma) you just die with no chance to flare (dont have flares but... you know what i mean) or do an evasive maneuver.
