What minimum altitude is required for a parachute jump?
In the UK it is 2200 feet for a round canopy deployed via a static line, 3000 feet for a RAPS, or square, canopy via static line. Only parachuting students would ever jump a static line, so it’s 2500 feet for licensed jumpers in freefall, but I have seen the rules being bent on particularly bad weather days, and they go from 2000 feet (but it still says 2500 feet on the paperwork). A BASE jump can be done from as little as 200 feet, less than that is not a calculated risk anymore, it’s a lottery with your life.
