Diagram showing the path of a driver performing a U-turn.A vehicle with a smaller turning diameter will be able to perform a sharper U-turn. The turning radius (alternatively, turning diameter or turning circle) of a vehicle defines the minimum dimension (typically the radius or diameter) of available space required for that vehicle to make a semi-circular U-turn without skidding.
Two-circle flow will also result in another merge. In two-circle flow, turn radius is of little importance, because what matters is which fighter can get back to the merging place first. Two-circle flow is a turn rate fight, and the angular advantage usually goes to the aircraft with the higher turn rate at its corner speed.
Not all the figures are competition figures, and so some do not have diagrams to accompany the description. Reading the diagrams, a figure begins at the small solid circle and ends at the short vertical line. Inverted flight (negative g) is depicted by dashed red lines. The small arrow indicates a rolling maneuver.

Ackermann geometry. The Ackermann steering geometry is a geometric arrangement of linkages in the steering of a car or other vehicle designed to solve the problem of wheels on the inside and outside of a turn needing to trace out circles of different radii.
We have different kinds of “rotary traffic islands,” including neighborhood traffic calming circles, mini roundabouts, single-lane roundabouts, and multi-lane roundabouts.
One solution to the steering problem is to use two separate drivetrains, each driving one track. This maintains power to both tracks while steering, produces a wide range of turning circles, and even allows one track to be reversed while the other moves forward, allowing the tank to turn in place.
