ACE Aeronautics plans to equip Sikorsky Black Hawk helicopters with Skyryse’s SkyOS software and digital flight controls under a strategic partnership signed between the two companies. Skyryse’s system removes the mechanical helicopter cyclic, collective, and pedal flight controls and avionics and replaces them with a single fly-by-wire control stick and two touchscreen cockpit displays.

Pilots can control the Skyryse-modified helicopter via the displays or using the control stick, with full envelope protection and simplified flight control that prevents pilots from exceeding the helicopter’s limitations. At the same time, the helicopter’s full capabilities are available.

Skyryse and ACE will offer the modified Black Hawks to public safety, search-and-rescue, and other lifesaving service providers, including military operators.

Skyryse’s first project, a similarly modified Robinson R66 helicopter called Skyryse One, is on track to receive an FAA supplemental type certificate next year. The El Segundo, California-based company hasn’t yet revealed the timeline for approval of the Black Hawk modification.

“The Black Hawk helicopter is a proven workhorse that has performed countless missions around the world for almost 50 years,” said ACE CEO Rich Enderle. “We’re excited to partner with the leader in rotorcraft flight controls to enhance the safety and operational capability of the aircraft, and we’re looking forward to seeing SkyOS elevate the experience for our customers.”
