AIR FORCE T-38 TRACK INTERMEDIATES
Unlike the High Yo-Yo, which is designed to slow closure and decrease aspect, the Low Yo-
Yo (Figure 5-7) is used to create closure by momentarily increasing aspect (lead pursuit) and
diving in the vertical to gain airspeed. A Low Yo Yo situation typically occurs when the
formation is separated, such as at the end of extended trail maneuvering or after a Breakout/Lost
Wingman exercise and Lead commands a Turning Rejoin away from Wing.
Command a Turning Rejoin.
(1) Observe the wing rock and add max power while initially turning toward Lead.
If Lead is turning away, execute a Low Yo-Yo.
(2) Pull lead pursuit on Lead by maneuvering your aircraft to point ahead of Lead.
Your choice of lead pursuit angle should be commensurate with your range from Lead. Pull no
farther than a 9 aspect. If you need to pull more lead later, roll out to drive to less than a nine
aspect then pull lead again.
(3) With sufficient lead pursuit, roll out and lower the nose to gain airspeed. You
are essentially cutting across the circle of Lead's turn.
(1) Command a Turning Rejoin in your choice of direction by rocking the wings
three times. The first wing rock should be in the direction of the Turning Rejoin. The magnitude
of the wingrock should be in accordance with how far Wing is away from Lead. As a guideline,
make the wingrock so there is no doubt Wing can see it.
(2) Maintain 30 degrees of bank, on altitude, 150 knots. You can be off any of
these parameters, but do so for a reason. For example, you can command a Turning Rejoin while
you are climbing; just let Wing know what your airspeed is.
(1) Observe the Turning Rejoin signal and pick the appropriate pursuit curve to get
on the rejoin line. High Yo-Yo, Low Yo-Yo if appropriate.
(2) Maintain lead slightly above the horizon and maintain the 45-degree rejoin line
(45 aspect) use power, altitude, and pursuit curves to control and angle-off. The visual reference
should be Lead's horizontal stabilizer bisecting the opposite wing. Plan Angle-Off to be near
zero as you get close to the Route position on the inside of Lead's turn.
(3) Make an expeditious, controlled Rejoin on Lead, stabilize in the Route position.
This will look like the position in Primary Forms where you cannot get a T-34 between you,
right before you "go down like a V" during the "Break-up and Rendezvous."
From Route position, ease into Fingertip.
