USPA Skydiving B License Practice test

Ground speed in skydiving specifically refers to the speed at which a skydiver is approaching the ground. It takes into account both the vertical speed of the skydiver as they descend and any horizontal movement caused by wind or their body position. Ground speed is critical for a variety of maneuvers during landing, as it helps skydivers gauge their descent rate and the appropriate timing for deploying their parachute, as well as ensuring they land safely and accurately.

The other options, while related to skydiving, denote different aspects of the experience. The speed of a falling jumper in freefall would refer to their vertical fall speed rather than their speed relative to the ground. The speed of the aircraft is pertinent to the skydive operation but not to the ground speed of the jumper. Lastly, the speed required to deploy the parachute pertains to the necessary conditions for a safe deployment but does not define ground speed. Understanding these distinctions helps a skydiver ensure safe practices and effective landing procedures.
