To Park a Plane
An essential part of training is feedback. Users need to know how well they did and how to improve. For this, we created a grading system based on two factors: how close the plane is to where it should be and the angle the plane is at. Ideally, the plane should be straight and land right at the mark, but of course, nothing is perfect so we used a parabolic grading curve that is forgiving of being a few degrees off. Once users receive their score, they can either move on to a bigger plane or retry the current plane. We wanted to make sure that users could not only learn the gestures used for aircraft marshalling, but also be comfortable applying that knowledge to guide an actual plane.
