Use the chart to estimate your freefall time according to your approximate terminal velocity and the distance in freefall.Subtract your opening altitude from your exit altitude to determine the length of your freefall.Determine your approximate terminal velocity by taking actual measurements of jumps with known exit and opening altitudes (this can be done by timing video tapes, by having someone on the ground time the skydive, or using a recording altimeter). Welcome to Skydive Cross Keys A premier destination for skydiving in New Jersey, Skydive Cross Keys is known for high safety standards and a warm friendly vibe.To determine the approximate amount of freefall time to expect on a jump and to log a realistic amount of freefall time for a jump, use the following procedures:.50 mph (73.3 feet per second) for wing-suit jumps.160 mph (235 feet per second) for vertical head-down or standing orientation.120 mph (176 feet per second) for belly-to earth orientation.But once you hit 5,000 feet above the ground, your tandem instructor will deploy your main parachute. This is when your only support is your drogue chute and you are enjoying the fastest speed of your entire freefall. The chart lists freefall times based on three different typical terminal velocities and provides an exit altitude reference for 3,000-foot openings. Depending on your jumping altitude, skydivers typically enjoy 30 to 90 seconds of freefall.skydiving discipline, e.g., vertical orientations.total weight of the jumper including equipment.Many factors affect the rate of fall or terminal velocity in freefall.The amount of freefall time logged for each jump should be actual time.Each skydiver should log every jump made, including the amount of freefall time experienced.The following table will assist in estimating the approximate amount of freefall time to be expected from a given altitude and in logging the correct amount of freefall time for a given jump.Hazards Associated with Movement JumpsĦ-3: Freefall Rate of Descent and Time Table A.
Training for unintentional water landings People also often lose perspective for time. This is because they don’t know how it feels, and they rely on someone else to bring them down safely. For first-time jumpers, skydiving can be scary.
