JA1 Pulse
Standing tail-sitter biplane; first responder
Jump Aero's JA1 Pulse is a single-seat, all-electric biplane tail-sitter that flies a paramedic or first responder, not a patient, to the scene. Jump lists a 150 kg payload, a 250 kt dash, and an operational radius of about 50 km. Flight time is not published. Launch is in under 60 seconds, with eight cross-linkable 11 kWh batteries and a ballistic airframe parachute. It is trailer-portable without disassembly. In August 2025 the founder said a subscale demonstrator had transitioned on the full-scale flight computer and the full-scale prototype was midway through its build, with first hops expected around 2026. Jump plans to operate it as a light-sport aircraft under Part 91. Customers include Falck and Electro Ventures, and it has five US Air Force contracts. Not certified; no price.
