• Goal is to move the wing from the parade position on one side to the other to meet operational maneuverability requirements
  • Used to:
    • Minimize wings exposure to sun
    • Area management
    • Breakup and rendezvous
    • Returning to base (overhead maneuver)
  • The maneuver is performed slowly to control movement
  • No faster than a walking pace
  • Throttles control nose-to-tail
  • Nose controls step-down
  • Angle of bank controls crossing rate
  • Two Types:
    1. Box
    2. V
  • As with parade position, all corrections should be "3 part power corrections"
Cross-under Signal
Figure 1: Cross-under Signal


  1. After receiving the cross-under signal from lead the wingman will acknowledge
  2. Reduce the power slightly and increase step-down
  3. Box:
    • Move straight back to achieve 10' of nose-to-tail and 15' of vertical separation
    • You will be looking down the leading edge of the vertical stabilator
  4. V:
    • Move back at an angle while descending to establish 10' of nose-to-tail and 15' of vertical separation
    • You will see the front portion of the MDC cord on the underside of leads intake or the canopy bow on the wing line
  5. Add power early before you reach the desired position
    • Box: stabilize and move to the opposite side
    • V: stabilize in column
  6. Add power and increase power as you maneuver back to the other side
    • Project yourself outside of leads wingtip to avoid driving too close

  • On div form, cross-unders are done when looking up the previous aircraft's leading stabilator edge

T-34C Procedure:

  • LEAD: "Wingman in position, area clear, cross-under signal,"
    • (hold for 2 count)
  • ICS: "Ready... down,"
  • LEAD: "Ready...look"
  • WING: "Cross-under signal, acknowledge when they look,"

  1. Wing will acknowledge the signal with a head-nod
  2. Wing will step down 20'
    • Simultaneously reduce power and apply forward stick
    • Leads exhaust stack will be tangent to the leading edge and the ventral point directly over the cutout
    • Add that power back in once reaching the step down to avoid being sucked
  3. Wing will then move in a straight line across with the same 20' nose-to-tail clearance
    • The wing will dip slowly to the left and power adjustments may be necessary to ensure you move straight
    • Power increase should be expected and should take at least 5 seconds to cross
  4. Wings nose should never be under leads tail, EVER
  5. Wing will arrest motion with a right wing dip on the other side bearing line
  6. Wing will then move up into parade position
    • Using slight power increase and back stick pressure
  7. Reference points are the same just on the other side
