In real aviation, the barrel roll is a graceful, low-G maneuver when done correctly. In simulators, practice until the motion feels smooth and the altitude loss is minimal. Never attempt without proper training and legal clearance.
A barrel roll is an aerobatic maneuver where the aircraft follows a helical (corkscrew) path around an imaginary center point. Unlike a simple aileron roll, the barrel roll combines both roll and pitch, resulting in a constant positive G-force and a net change in heading of 90–180 degrees if continued. do barell roll
