The Butler HX-series canopies are our high speed canopies. These canopies were designed to withstand the speeds and weight-loads of modern aircraft. The astronaut on SpaceShip II that parachuted to safety when it failed at 40,000 ft was wearing a High Altitude System equipped with an HX-500. Our HX-series canopies are equipped with a patented Sombrero (dome-shaped) slider to achieve the highest rated performance in the industry.

*Knots equivalent airspeed: the calibrated airspeed corrected for adiabatic compressible flow for the particular altitude.
**Knots indicated airspeed: the speed shown on an aircraft’s pitot-static airspeed indicator.
† FAA certified weight limit which results in a rate-of-descent of 24 ft/sec at sea level.
†† Butler Parachute Systems recommended weight limit which results in a rate-of-descent of 20 ft/sec at sea level in order to reduce the potential for landing injuries.
