Flight Procedures
Air Combat Maneuvering
DISPLACEMENT ROLL
If you are rapidly closing on a bandit with lateral separation and low TCA, a displacement roll would
be a better maneuver to choose than a high yo-yo. A displacement roll reduces excessive closure by
displacing your aircraft relative to the bandit’s flight path. Additionally, the maneuver can move your
aircraft to a different plane of maneuvering (lag pursuit) behind the bandit, while maintaining your
energy package.
You will practice this maneuver as a follow-on to a low yo-yo. Initiate the displacement roll from
anywhere in the low yo-yo by attempting to align fuselages on the inside of the bandit’s turn. Failing
to align fuselages will increase your TCA. Raise your nose above the bandit, and roll away from the
inside of the turn toward the bandit’s six. If you do not raise the nose, you will execute a simple
aileron roll which neither displaces your aircraft nor controls your closure. Use rudder and back stick
to keep your fuselage aligned. Adjust your rate of roll to arrive in a firing envelope. If your intentions
are to increase your nose-to-tail while maintaining the preferred lead or pure pursuit, pull the nose
higher in the vertical while increasing your rate of roll, as in Figure 13.
