The Belly to Back barrel roll is the first “transition” you will learn during your flight progression. It is important to note that no transitions should be performed without careful discussion with your instructor on the safety requirements and specific technical details required.

The primary objective is to be able to safely and successfully start in a neutral Belly Fly body position in the center of the tunnel and perform a half-barrel roll transition from your belly to your back, ending in a neutral Back Fly position, still in the center of the tunnel, and at the same altitude that you started.
