Flight phase descriptors
| Descriptor | Definition |
| Flight time | Duration (ms) elapsed between jockey losing seat (which they are unable to recover) and sustaining the first contact/impact |
| Fall height: subjective assessment of the height at which the jockey’s fall/unseating occurs | Low: fall/unseat occurs from a height that does not exceed that of an average adult human |
| Moderate: fall/unseat occurs from the height of a full-sized horse (height of the horse’s withers) | |
| High: fall/unseat occurs from the height of a full-sized horse in flight/jumping and exceeds that observed within the low-moderate ranges | |
| Direction of fall: the direction by which the jockey falls from the saddle | Anterior |
| Lateral | |
| Posterior | |
| Anterolateral | |
| Posterolateral | |
| Flight/fall rotation (vertical axis): the amount of rotation that occurs upon the vertical axis (where observed) during the flight phase of the jockey’s fall | ≤90° |
| 91°– 180° | |
| 181°– 270° | |
| 271°– 360° | |
| Direction of rotation (vertical axis) | Clockwise |
| Counterclockwise | |
| Flight/fall rotation (mediolateral axis): the amount of rotation that occurs upon the mediolateral axis (where observed) during the flight phase of the jockey’s fall | ≤90° |
| 91°– 180° | |
| 181°– 270° | |
| 271°– 360° | |
| Direction of rotation (mediolateral axis) | Forwards |
| Backwards | |
| Flight/fall rotation (anteroposterior axis): the amount of rotation that occurs upon the anteroposterior axis (where observed) during the flight phase of the jockey’s fall | ≤90° |
| 91°– 180° | |
| 181°– 270° | |
| 271°– 360° | |
| Direction of rotation (anteroposterior axis) | Clockwise |
| Counterclockwise |
