Snap rolls also have to be flown normally on a straight line. A snap roll is similar to a horizontal spin. It is an autorotation with one wing stalled. Figure 1 shows the symbol for a regular snap roll.  Figure 4 for an outside snap. In the regular snap, the plane has to be stalled by applying positive G forces. In an outside snap, the plane is stalled by applying negative G. In both cases rudder is then used to start autorotation just like in a spin
