To strike my missiles at them before their flare cooldown is done. On average, missile flight takes 4-5 seconds for 4km and 3-4 seconds for 3km. (Aircrafts) In this close strike requires aircraft maneuvering to avoid their AA guns. And your full throttle maneuvering makes their AA missiles take more time to strike you. The result is you can earn 0.5-1 seconds to make your flare cooldown done. So I'm always do maneuvering. Not just for cool.
