What does "chop" refer to during a skydive?

"Chop" during a skydive specifically refers to a sudden loss of lift or an unexpected change in canopy performance. This term captures the essence of an abrupt and potentially hazardous situation where the parachute may behave unpredictably, leading to a decrease in lift. This can create challenges for the skydiver as they approach landing or maneuver through the air.

Understanding this concept is critical for skydive safety, as it emphasizes the importance of being aware of the canopy’s behavior and recognizing shifts in performance that could affect control. Proper training and experience teach skydivers how to respond to such situations calmly and effectively.

The other options might refer to different aspects of skydiving but do not encapsulate what "chop" specifically means. For example, a gradual increase in altitude or a decrease in speed during freefall relates to aspects of ascending or descending under different conditions, while control over canopy direction pertains to steering and maneuvering during flight, rather than addressing the sudden changes described by "chop."
