Basic dogfight superiority training & manoeuvres.
“A useful type of out-of-plane manoeuvrer employed to decrease AOT are various barrel rolls called displacement rolls, in order to shift the aircraft laterally from its projected flight path onto a new flight path. By controlling the roll rate the pilot can control the degree of displacement. An attacker following a more manoeuvrable opponent may become stuck in lag pursuit (outside the defender's turn radius), unable to achieve a firing solution.”
“By displacing the turn, the two aircraft's flight paths will eventually cross. The AOT will then decrease until the nose of the attacker's aircraft points momentarily at the defender, and then ahead of the defender. A displacement roll is a good tactic when ever a reduction in turn radius is needed, but a decrease in turn rate is allowed.“
