Air Combat Maneuvering
disadvantage is that it causes greater speed and energy loss. Starting the roll below 275 KIAS may leave
you too slow and unmaneuverable at the completion. Or even worse, you may not have enough speed to
complete the maneuver and find yourself defenseless as the bogey saddles in for a shot.

Figure 25: HIGH-G ROLL UNDERNEATH
If you have to use a high-g roll and your airspeed is less than 275 KIAS, execute the roll underneath,
(Figure 25), ensuring that your altitude is at least 2,000 ft above the deck, and the bogey is within the
1,500-ft range. To execute the high-g roll underneath, attempt to force an overshoot the same as you
would if you were going over the top: increase back stick, reduce power, and extend your speed brakes.
Continue your defensive pull until you have generated the highest possible angle off and closure. Roll in
the direction of the defensive turn while maintaining back stick and apply full bottom rudder throughout the
roll. When your lift vector starts above the horizon (halfway through the roll), maintain 19-20 units AOA
while adding full power and retracting speed brakes. Continue rolling to wings level, neutralize your rudder
to stop the roll, and maintain back stick to achieve a nose-high attitude, while checking for the bogey’s
position.
The advantages of the high-g roll underneath are that gravity assists in the early stages and speed loss is
reduced, providing for better maneuverability. The tradeoff is that it results in considerable loss of altitude.
Regardless of the type of high-g roll, if the bogey overshoots outside the turn, continue to pull up and into
the bogey in order to increase AOT. Attempt to force the bogey into a scissors as you look for
opportunities to disengage. If the bogey is inside the turn, continue to pull into the bogey, attempting
another maneuver to prevent a guns solution.
Jink-Out
Another last-ditch maneuver, a jink-out destroys a guns solution by maneuvering out-of-phase while
retaining the potential either to neutralize a follow-on maneuver by the bogey or to seek an opportunity to
disengage. As the bogey approaches a medium-to-low angle, in-close firing solution, increase your turn to
create an overshoot. Assuming an overshoot does not occur and the bogey begins to pull lead, apply
negative g to push your aircraft out of the bogey’s predicted tracking solution. Maintain this negative g for
approximately 2 seconds. During this negative-g extension, the bogey will be reducing his g to reacquire
sight, which will eliminate his lead pursuit. Immediately follow this with a positive-g break turn for 2 to 4
seconds back into the bogey’s position, which should establish an out-of-phase overshoot. Repeat as
necessary.
