01 — Overview

What it actually is

Dynamic 2-way (D2W) and 4-way (D4W) are the two competitive versions. Two or four athletes execute coded movement sequences — lines (linear counter-flow moves), rounds (chamber rotations), moves (vertical acrobatics) — in the shortest possible time. Exists only as a tunnel discipline; no freefall counterpart. FAI recognized it in 2015 and organizes Indoor World Championships since then.

Editorial note

Aero Gravity (5.2m, 370 km/h) is one of the world's best tunnels for competitive dynamic. Top Italian teams train here and at international events. Many dynamic flyers have never made a real jump.
