Regarding flight control for planes, there exist 3 axes: roll, pitch, and yaw. Something that I've been curious of recently is the ability to control a plane without direct yaw control. Let's go for an extreme example, imagine you only have control over a plane's pitch and roll. Although you would typically use the yaw to assist in turning a plane left and right, couldn't you accomplish turning left and right simply by rotating the plane by it's pitch and roll axis? Could you not roll the plane 90 degrees, and then use the pitch control, and then roll the plane back 90 degrees? This could indirectly steer the plane left or right, correct? In most scenarios, you would never roll the plane 90 degrees, but you could roll it less than 90 degrees and then alternate the pitch back and forth to the keep the plane level. I attempted to search for this concept but came up empty handed... For those of you experienced with planes, is this something that is ever done, or is it much easier to add a rudder for direct yaw control?
