- Engage with Technology:
Attendees can get hands-on experience by downloading the ACROWRX app, a platform used by competition and airshow pilots for flight evaluation and improvement.
The app allows you to follow the flights from multiple angles, from the pilot's view to the judge's view, enabling you to score the flights in real-time. Join in the excitement and add your scores to the mix.
ACROWRX APP : How does it work?
When the IAC Demo starts, you'll be able to watch the flights with three different views:- CHASE VIEW — follow the aircraft and rotate around it in 3D
- JUDGE VIEW — the same perspective seen by the official judges
- MAP VIEW — shows the flight path over the aerobatic box
On the screen, you’ll see the Aresti Code — a diagram that represents the maneuver the pilot is flying. Think of it as the "sheet music" for an aerobatic pilot. You’ll be able to score each pilot’s performance. It’s a great way to participate in the demo! You can submit your scores only once.
