>>63961984LPI function is precisely about working in passive mode as much as possible; at most, using active scanning on irregular intervals to keep the rwr from picking it up as enemy radar is possible and useful, but can't give an up to date picture.
The main tactic if you are not using awacs is to have the stealth fighters work as a team, one actively scanning for situational awareness while also serving as bait, ready to go dark if attacked while the others counter.
