Roll Trainer: Test Your Aerobatic Judging Skills

As a longtime aerobatic pilot and judge, I’ve always been fascinated by how difficult it is to accurately assess roll angles during a flight. The difference between a 90-degree point and an 80-degree point can be subtle from the ground, but those degrees matter in competition scoring. That’s why I created the Roll Trainer.

What is Roll Trainer?

Roll Trainer is a browser-based game that puts you in the judge’s seat. Watch an aircraft perform rolling maneuvers and try to identify the exact roll angle. It’s a fun way to practice the visual assessment skills that aerobatic judges develop over years of experience.

Why Roll Angle Matters

In aerobatic competition, precision is everything. A competitor might perform a roll that stops at what they think is 90 degrees, but from the judge’s perspective, it looks like 85 degrees. That five-degree error results in a deduction. Experienced judges develop an eye for these angles through countless hours of practice.

For pilots, understanding how judges see their maneuvers can help them adjust their sight picture and improve their competition scores. For aspiring judges, it’s a way to sharpen their assessment skills without needing to be at an actual contest.

A Training Tool for Judges and Pilots

Whether you’re:

• An aspiring judge looking to develop your eye for roll angles
• A competition pilot wanting to understand the judge’s perspective
• An aviation enthusiast curious about what goes into aerobatic judging

Roll Trainer offers a simple, engaging way to test and improve your skills.
