What is it called when you roll without yawing or pitching? My instructor made me do an exercise that consists of banking the sailplane left and right around 30 degrees without moving from the axis. I need to aim for a specific point, and start with the exercise. This is a coordination exercise but does it have a name? It's like a dutch roll but I need to stay in the roll axis without moving.
In the aerobatic community we would call that the beginning of an Aileron Roll.

It's harder than it looks.
