Both the inside and outside loop are sometimes casually referred to as a 'loop the loop'. Outside loop A vertical circle entered from straight and erect level flight, canopy pointing out of the loop. Loop can be above or below the straight and level entry altitude, from erect or inverted attitude. (Draws extreme negative G) English bunt
The Aresti Catalog is the Fédération Aéronautique Internationale (FAI) standards document enumerating the aerobatic manoeuvers permitted in aerobatic competition.Designed by Spanish aviator Colonel José Luis Aresti Aguirre (1919–2003), each figure in the catalog is represented by lines, arrows, geometric shapes and numbers representing the precise form of a manoeuver to be flown.
The train reaches a max speed of 57 miles per hour (92 km/h) and heads through a negative-g stall loop, a one-of-a-kind inversion. This inversion is similar to a Norwegian loop, except the train enters a non-inverted dive loop followed by a sidewinder before exiting in the opposite direction. The train moves through a corkscrew and a cutback.
A flight envelope diagram showing V S (Stall speed at 1G), V C (Corner/Maneuvering speed) and V D (Dive speed) Vg diagram. Note the 1g stall speed, and the Maneuvering Speed (Corner Speed) for both positive and negative g. The maximum “never-exceed” placard dive speeds are determined for smooth air only.
The aircraft will rotate on all three axes and perform three end-over-end negative "g" tumbles, each tumble being at about 45° to the plane of the last. [1] The maneuver ends when the aircraft runs out of momentum and begins falling with enough speed for the airflow past the control surfaces to stop the tumbling. Neutralising the controls then ...

In modern aerobatics, this maneuver, if executed pre-stall with a non-zero turning radius at the top of the climb, is known as a wingover. If the rudder turn is executed right at the initiation of the stall, the resulting yaw occurs around a point within the aircraft's wingspan and the maneuver is known as a stall turn or hammerhead.
Zero-G (where the net vertical G-force is 0) is achieved when the downward acceleration of the train is equal to that due to gravity; where the downward acceleration is greater, negative Gs arise. [citation needed] The zero-gravity roll is a roll specifically designed to create the effect of weightlessness and thereby produce air time.
