What is High-Speed Yo-Yo maneuver

What is High-Speed Yo-Yo maneuver

When the attacker realizes that he is unable to stay on the inside of the defender’s turn, he relaxes his angle of the bank a little, then pulls high.

As he comes over the top he is inverted, looking down at his opponent through the top of his canopy. His speed falls due to the climb, and this diminishes his radius of the turn.

The Ig of gravity is utilized by turning in the vertical plane, which reduces the radius of turn still further. The attacker should then be well placed to slide down into a firing position.

The high-speed yoyo is a very difficult maneuver to perform well and demands perfect timing and precise execution. If it is commenced too early, the defender can counter by pulling up into the attack.

If started too late, the attacker is forced to pull up at an excessively steep angle to avoid overshooting. This allows the defender to disengage by diving away. A common fault in executing the high-speed yoyo is not pulling the nose high enough.

This can result in the attacker ending directly above the defender. Some pilots find that they obtain better results from a series of small yoyos than one large one. A variant on this maneuver, used to prevent overshooting or to reduce the angle-off, is rollaway.

What is Split S maneuver

In this the defender rolls inverted and dives away vertically, pulling out in a direction opposite to that of his opponent.

Most defensive maneuvers are designed to counter an attack coming from astern, mainly by forcing an attacker to overshoot. What are the attacker’s needs?

Much depends on whether he is planning a missile or gun attack. As we saw in the attack phase, a missile attack should be fast, deadly, and conclusive.

But, as World War, I German Chief of Staff von Moltke observed many years ago: plans rarely survive contact with the enemy.

The fighter pilot should be prepared for his attack to fail and know precisely what he will do next, either disengage or enter into maneuvering combat.

If his attack is from head-on, much will depend on the maneuver potential of the two opponents.

The more maneuverable fighter will have the edge in a turning fight. (The more maneuverable fighter at this stage is frequently the one traveling slowest rather than the most aerodynamically capable.) If this is the attacker he should endeavor to pass wide of his opponent to give himself turning room.

If there is any doubt about relative maneuver potential he should pass close to deny his adversary turning room, then pull high in the turn. In either case, he should pass down-Sun so that his next change of direction forces his opponent to look into the dazzle.

If after a head-on pass both aircraft pull high vertical ascending scissors may result.

A missile attack from astern is normally made at a high closing speed. If the attack fails the attacker must zoom climb to dissipate his excess speed if he wishes to continue the fight, although it is easier and probably safer to disengage at this point.

A gun attack should be made with an overtake speed of about 50 knots (just under 90 feet, 2 7m) per second). This gives time to track the target in the sight, minimizes the risk of overshooting and retains an energy advantage for maneuvering combat.

The defensive maneuvers described earlier place much stress on forcing an attacker to overshoot It is obviously important to avoid overshooting, so how is it done?

An overshoot is caused by one or two factors. The first is an excessively large angle subtended between the fuselages of the respective aircraft. The second is excessive closing speed. This is difficult for the attacker to spot until he is fairly close in.

Either way, the attacker is faced with overshooting. His first remedy is the high-speed yoyo.

The Split S is a time-honored method of disengaging from combat. Known to the Royal Air Force as the Half Roll and the Luftwaffe as the Abschwung, it uses maneuver in the vertical plane to evade an attack.

  1. I used to LOVE History Channels “Dogfights”!!! Have it on DVD. I like that you included to help explain the High Speed Yo Yo and the Split S (very helpful). Good stuff, even if you’re riding on the “Dogfights” TV show’s coat tails here. Wish someone would bring that back, they never did an episode about the Navy’s F-14 Tomcat even though they showed the Tomcat in the opening credits.
