Dynamic (tunnel)

Purely indoor discipline. Progression measured in tunnel hours (not jumps): base position → first coded moves → D2W sequences → D4W team → competition. Requires structured coaching and video debriefing.

01 — Context

The discipline in brief

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.

Key gear

Fitted dynamic suit (Tonysuits Tony Dynamic, Deepseed). Technical socks. Mandatory protective helmet. No canopy — flown without skydiving gear.

02 — Prerequisites

What you need to start

Min. jumps
Min. license
Tunnel hours
20h
Risk
Low

No skydiving license needed — dynamic is a standalone indoor discipline. Minimum 15-20 tunnel hours with structured coaching before clean dynamic. Requires tunnel ≥4.3m and speeds ≥280 km/h.

03 — Roadmap

4 milestones in sequence

01
Tunnel hours
Base head-up + head-down — 10 hours

Technical prerequisite: stable position in both postures. Without clean foundations dynamic becomes a search for compensations.

Time
3–9 mo
Cost
6000–12000 €
02
Discipline
Coded dynamic moves

Lines (forward-back), rounds (chamber rotations), moves (vertical acrobatics). Dedicated dynamic coach mandatory.

  • Clean line at speed
  • Complete round on time
Time
3–9 mo
Cost
2000–6000 €
03
Discipline
D2W sequence (2-way)

With a partner, build choreographed sequences of 6-10 moves. Synchronization, timing, partner-reading are new skills compared to solo flying.

Time
6–12 mo
Cost
3000–10000 €

Competition
FAI Indoor World Championship / D4W

The competitive dynamic circuit is now structured. FAI World Championships every 2 years. Top Italian teams train between Aero Gravity Milan, Realfly Sion, and Weembi Lille.
