military dork missing the joke mode: to use chaff effectively, combine it with flares and fire in large bursts, and then maneuver such that the flare/chaff cloud is between you and the missile. if you don't couple the chaff with flares and with the appropriate maneuvers (placing the cloud between you and the missile), the missile will ignore them and focus on the biggest heat source - your engine (jet exhausts specifically i think)

sometimes i think you can also use the sun to confuse missile lockon but that seems like something they would have fixed by now. the thing about missiles is that they have less fuel and less wing surface than a jet, so the jet can raise altitude easier and for less fuel, and can maneuver more easily. the missile is faster for a short time, but if you increase altitude (it costs more fuel for the missile to go up) and keep it to your 3 or 9 clock position (it costs more fuel and reduces speed to turn) you can outmaneuver it and waste its fuel. if the hostile missile is moving straight and not turning you are doing it wrong.
