RENDEZVOUS: A maneuver where the formation aircraft are maneuvered into a position
where a join-up may be performed.
SHAKE OFF: A visual signal (negative head shake) given by the Wingman to indicate he is not
prepared to execute the next maneuver or required action.
STACK: A visual checkpoint on the T-6A, referring to the trailing edge of the exhaust stacks.
STEPDOWN: The vertical distance between the lead and wing aircraft.
SUCKED: A condition in which the Wingman is positioned aft of a designated bearing line.
TAIL CHASE: An exercise designed to demonstrate the concepts of lead lag and pure pursuit
while dynamically maneuvering the section.
TERMINATE: A radio call (normally initiated by the flight Lead) to terminate an exercise or
maneuvering. This differs from the Knock-it-off call in that it is anticipated/expected (i.e., after
cruise maneuvering). The terminate radio drill (if initiated by Lead) will be conducted as
"(Tactical Call sign), Terminate... (Tactical Call sign)-1, Terminate"
"(Tactical Call sign)-2, Terminate"
TRAIL: A formation pattern where the wing is directly behind the lead aircraft.
UNDERRUN: A maneuver utilized to allow the wing aircraft to pass below, behind, and outside
the lead aircraft's radius of turn in the event that the rendezvous becomes unsafe.
